MAJOR DESIGN FLAW?:  ----  IPAD in car connected to 12V outlet

i have my usb power cord plugged into a device which converts the 12V to usb power.
When I do this the IPAD works fine except for audio output. There is a loud buzzing on the audio.
When I play audio and it is not hooked up to car usb, no buzzng.
Since very cheap electronics can use car power to produce clean sound, why does not the $800+ 64GB 3G do it?
Seems like a major design flaw if I cannot plug it into the car and listen to music during long trips.

One way to suppress engine noise/digital hash - which is very common and getting worse in cars as more computers, upwards of 100 in some cars as well a multiple networks connecting them in - is to place a ferrite choke on the cable powering the device. Some USB cable have them built in. They look like a cylinder perhaps 2 inches long and 3/4 inch in diameter molded onto the cable.
They can also be externally used which is probably the only way with the USB to iPad connector cable.
Radio Shack has them see [*this link*|http://www.radioshack.com/product/index.jsp?productId=3012599] for example. Their web site says they are available in most stores.

  • Content Server News Portlet major design flaw ?!

    I ran into a Content Server 6.1 issue which is really frustrating me. I am wondering if I am doing something wrong or if it is a design flaw: 1. I created a content server news portlet "out of the box" and added it to my MyPage.2. I created and published 2 news articles.3. I edited the 1st article and just saved it. I did NOT PUBLISH it.4. I edited the 2nd article and PUBLISHED it. The news index is re-published automatically to reflect the changes of the 2nd article which has been published. But the index now displays the changes of BOTH articles, even the unpublished! Furthermore the 1st article can't be opened from the index anymore if the name property has been changed. As the published file name changes with each version and especially when the name is updated, the news index links to the new published file name - but it has never been created as I didn't publish the 1st article! I understand why this is happening: The index content item holds a list of all article content items and is published whenever an article is published / deleted / expired. But until now I thought that content server is holding the last published version and includes this into the list until a new version is published. That's not the case! Imagine this on a production environment with workflow activated: one article was approved and published while the other still needs to be reviewed, but it's (unreviewed) index data like headline etc. is already displayed in the index?! And in worst case the article can't even be opened. You just get the server error "page not found". Many of my content items for a current big project follow the idea of the news template, e.g. HR Staff Overview (persons = articles, overview = index), so I am kind of stressed by what I found out. Has anybody made similar a experience and found a workaround for this? Perhaps one of the support people could explain how the news portlet is intended to be used with this severe behaviour? Am I expecting too much? Is updating an already published article not possible? But why are version mechanisms included for content items then? I appreciate your comments. Thanks.

    Thanks for the quick reply.
    We are using Content Server 6.1 with all Hotfixes installed and we are not planning to upgrade to G6 at the moment.
    As far as I understood the 'filtered.published' property contains the date the content item was published the last time. So it will always be 'true' if the item has been published in the past, no matter if it's currently published or not.
    The index template with the code snippet you sent will display the currently not published (but changed) item properties whenever another item was published. Have you changed the design in 6.2 so that properties of an item in a list property of another item are just copied and not linked?
    As a workaround I now compare the 'modified' property with the 'published' property and if it is greater or equal I don't display it in the index. But that's not the way Content Server was designed to behave, is it? With this solution I can suppress the item in the list if it has been modified after the last publishing, but of course I rather want to have the data of the last published version.
    Isn't that possible? Is it possible in 6.2? Is there any way to update Content Server to 6.2 without acquiring G6?

  • Mpg 4 in cover flow/column view major design flaws

    before leopard tiger had the ability to play in column view different parts of the song. you could navigate with the mouse to start it again from the beginning.
    you cant do this in leopard . unless im a jerk this is one of the most rediculous flaws or omissions. i have to click on the arrow but it doesnt start at the beginning once clicked. this is horrible!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    you need the old system back. and there is no whay to play songs in coverflow
    so what is going on here????????????????????

    mine starts at the beginning too
    but once its started and you stop it
    it will not return to the beginning without that slider
    where is apple man at????????????????????????

  • W530 drive bay design flaw - drive slide out of connectors​?

    Hi, I recently purchased a W530 with a hard drive bay and I've been experiencing trouble with the bay.
    The problem is that there is no mechanism in the drive bay to keep the drive "in bay" - i.e. connected. Because of a small gap between the drive and the wall of the bay the drive will slide out of the connector when the laptop is put in the bag vertically.
    this seems to me like a major design flaw in the drive bay, and I'm wondering if others are experiencing the same issue and know about any workarounds.

    First, you buy the right 12.7mm-high UltraBay HDD caddy adapter that is compatible with the W530. Second, you put the HDD in the hollow space of the caddy adapter and secure the HDD with the four tiny screws that are provided as part of the caddy adapter. Finally, you plug the whole thing (caddy **bleep** drive) into the UltraBay until the secure latch "clicks" and the caddy bezel flushes evenly with the right side of the chassis.
    There are no "rubber rails" involved.
    There are NO screws supplied with the Lenovo 12.7mm UltraBay caddy. The caddy presumes that you are using a Lenovo supplied HDD with the drive tray and the rubber rails Look at the diagrams on the flexible cover on the caddy. The Newmodeus caddy uses screws only (supplied) and does not need the rubber rails nor the drive tray.

  • E90: physical design flaws (but good features)

    I come from owning and using the 9500 Communicator and I recently 'upgraded' to the E90. I don't know how I managed to get one, what with all the 'production' issues of this model and the lack of stock, but I have had the 'low baseline' E90 for a few days now. I would like to make some comments and see if anyone else agrees/disagrees (and if Nokia is listening...)
    The Major Design Flaws are:
    1. Silvery, shiny bits that get scratched and worn.
    Why? The Communicator is a niche market that is going to only appeal to previous Communicator owners or techs who need computing power in a PDA. So why make it with shiny bits when we are all boring geeks? Within a couple of days I have scratches everywhere and reports of the inner cursor pad being badly worn... I've had the 9500 for over 2 years and it look pretty new. A colleague has the 9300 for the same amount of time and it looks pretty dog-eared!
    2. Camera lens is in primary place for a finger to smudge it.
    Why put it there or why put the inner cursor pad there when anyone using the cursor will have their finger wrapped around and touch the lens?
    3. What with all the problems of the keys scratching the inner screen why reduce the baseline?
    With the baseline reduced the two inner pads in the corner do nothing as they do not touch the (reduced) profile - and hence the screen scratch problem (?)
    4. Minor manufacturing problems?
    Uneven feet (it rocks!) and microphone/speak buzz problems?
    The good points are the new features (although not some changes especially when they were so perfect and useful in the 9500!)
    1. Big outer screen.
    2. Good resolution of screens.
    3. Quad band. 3G, etc.
    4. GPS. Maps, etc.
    5. Better media facilties and support.
    6. Better browsing and WLAN support.
    7. Better camera.
    8. Good hinge.
    Last thing, how is Nokia going to compete with Apple (iPhone in particular) if Nokia 'PC' suite is not available for the Macs?Message Edited by son_t on 31-Aug-200709:08 PM

    Really I respect you but I really cannot stand such low technical cultured objections.
    Well, I am not an MD in Mechanical Engineering, but I am looking at the facts. 9300i was much lighter than E90 and so is the SE p990i. If it is not a material problem, maybe it is a design problem. Maybe they put too much dead weight in. As an example, I think that, if Nokia used the same keyboard as on 9330i, the keyboard would have been much better and the phone a little lighter.
    I did not want to be offensive..
    I argue on solidity of 9300, personally I had 9300 and 9300i..
    The first also had a crack starting from an inner edge. The plastic used was not so good for me. The external cover soon became worn at the corner...but was lighter.
    The keyboard of 9300 was good..really good, but E90 is better: you can also retro illuminate it!
    Dead weight??? You have to know the weight optimization is one of the thing a designer perform. This process take not so much time, using Finite Element Analysis Software. It is a iterative process. It seems you miss the E90 has some metallic parts (it is a plus) and the plastic and the finishing is at highest level.
    Considering what is inside the E90 I found the overall dimension and weight are a great success!
    Let's see reliability of the finish, let's see reliability of the keyboard..time will give us the answers.
    I only agree about some minor design faults like the pad touching the inner screen.

  • IPad line-out design flaw - really!!!

    I just bought a cable that uses the line out of the ipad to use with my car stereo (Kensington 2-in-1 Charger and Audio Cable for iPhone/iPod)
    I first tested the cable by plugging it into some external computer speaker ... hissssss. Then into my nice NAD stereo amp .... hisssss and finally in the car ....... hissssssssssssssss.
    I then investigated the hissssssssing problem further and IT APPEARS TO BE A DESIGN FLAW WITH IPADS ! I ordered another cable from Amazon and got the same hiss. I even went to the Apple store and myself and a Genius even tried another iPad with this cable and still got a hiss. To top it off WE USED THE OFFICIAL IPAD DOCK with the line out (using another cable with mini plugs) and still got a hiss.
    So peeps, it appears that there is a major problem with the line out on the ipad. Perhaps these cables are at fault but how can you explain using a standard line out cable with mini plugs with the official Apple dock and still getting the same hiss. It's not a very loud hiss but definitely noticeable and renders the ipad line-out useless for anyone who wants to use this device to get better sound quality than the standard headphone out jack on home and car stereo units.

    Michael Morgan1 wrote:
    I plug an audio cable between the iPad the the home theater inputs and it sounds fine. And do the same to the powered speakers in the bedroom, and it sounds fine. Or connect a different cable from the iPad to the car radio's AUX to play audiobooks on the road, which sound great. And, of course, headphones sound fine too.
    I use my iPod the same way and I expect to use the iPad that way also.
    However, about a year ago I drove a rental car that had a USB connection to the sound system. According to the car user manual, that allowed the sound system to pick up sound from the iPod but also allowed the sound system to control the iPod via user inputs. Unfortunately, it required that the iPod have MS formatting and mine has Apple formatting so I never had a chance to play with it.
    Having said all that, I suspect (but can't prove) that the OP's problem is that, with ONLY the sound out function being accessed, the noise is reasonable. The cable includes other wires that are unterminated in this configuration. Unterminated wires are a good antenna. The antenna is picking up random noise (hiss) and transferring it to the audio.

  • I am U.S. iPhone 4S user traveling in China.  Data speed is too slow to be usable.  Verizon says that it because iPhone 4S connects to strongest signal even if slowest.  Any work arounds for this design flaw?

    I am U.S. iPhone 4S owner traveling in China.  Data speed is too slow to be usable.  Verizon says that is because iPhone 4S connects to strongest signal, even if slowest (virtually non-existent) data network.  Does anyone know how to work around this design flaw?

    I spent 2 months in china with my old iphone 3gs.  Both China Unicomm and China Mobile were accessible through my US phone.  (for you other users, yes my phone bill was sky high, but it's a small price to pay when you get instant access to your wife while you are gone... and to be able to use the google translate app).  I had a GSM phone (obviously) and had the ability to choose what carrier I wanted my phone to connect to (the same thing was available when I was in italy as well). 
    it was under
    general-> network> then there was a new field (that does not normally show up when in the US) that listed the available networks to connect to.  my phone always attempted china unicomm first, and switched to china mobile only when unicomm was unavailible. 
    but if wjosten is correct (and i imagine he is), cdma phones may not be able to choose what network to connect to. 

  • Design flaws in Apple iPad (mini)

    Broken screen in the bottom right corner holding it in portrait mode. Was just holding it and it snapped with my thumb. For sure i know this is a design flaw and Apple refused to replace it. If they do not fix this with the people it will turn for the worse. Not buying another Apple product until this is resolved.
    Just wondering what others' experiences are like? I know people are complaining about this same issue but I want my voice heard.

    Call AppleCare and ask to be transferred to Customer Service and talk to them. You might want to have your written proof available to fax or email to them proving that this is a design flaw, it will bolster your argument.

  • Design Flaw in Twin Frozr fans

    So, I'm finally creating a thread about this.
    There's been reports over the last few years about fans making rattling noises, grinding noises, high pitched whines, whether on cold boot, idle, high RPM, or constantly, and quite frankly I'm tired of MSI ignoring the issue.
    There is a design flaw with the Twin Frozr fans.
    MSI needs to publicly acknowledge this.
    Currently, the only way to get a replacement fan is to send your ENTIRE card in for repair.  Other more reputable companies will send you out an entirely new fansink attachment at no cost.  As one poster said it; "That would be like sending my car to Nissan every time I blow a tire"
    My personal experience with Twin Frozr started with Twin Frozr 2 on my GTX 460 Hawks.  The Talon Attack edition started to make a bad grinding noise on cold boot or if it actually got cold enough during idle operation.  When the card warmed up, the noise stopped.  Speeding up the fan to 100% sometimes also caused it to get rid of the noise, but that was only temporary unless the card stayed warm.
    My non-hawk exhibited rattling as well, but to a lesser extent.  No grinding noise on cold boot, just a low rattling.
    My next card was a GTX 670 PE with Twin Frozr 4.  Surely they fixed the issue by now right?  Wrong!  Within 30 days I started having fan issues.  This fan doesn't rattle, but there is a high pitched whine when the fan is in operation.  The faster the RPM, the louder the whine.  Most people don't even know they have this issue because of the subtle tone of the whine and it being muffled by the fan's air sound at higher RPMs.
    That's 3 separate graphics cards all exhibiting an issue with their fans.
    There's one thing in common with these issues; it's only caused by the fan closest to the I/O.  This boggles my mind.  Surely if there was a problem with the fan design itself it would affect both fans, right?  I just don't understand it.  This leads me to believe it's a design flaw with the Twin Frozr design.
    Some people seem to have an issue with the other fan, but it appears to be rare and not the same type of problem the majority of people are reporting.
    Seeing as they want you to lose your card (and $10+ to ship it) for weeks at a time to 'fix' an issue which will no doubt happen again, something needs to be done about this.  Their 'warranty' policy for this issue is completely unacceptable, as is the fact that the fans start acting up within a month of ownership.

    I don't think we have a MSI office in Portugal, most brands don't.
    Some stores are not reliable they buy from EU retailers some even from Asia retailers and usually they don't give proper support. In Lisbon you have stores like Globaldata, Nanochip, Chiptek and AquaPC they are in business for years, have good customer support and have also good prices.
    I'm probably not going to buy any MSI product from now on , for obvious reasons.
    Trying to contact a support shoudn't be this hard from a client , at this point I assume anyone that's doesn't want to lose time will just give up.
    As a consumer I was forced to RUN and TRY to find msi support , MSI support mail doesn't event exist , since I made this thread it still hasn't been changed.
    I really liked MSI ( I still have my 875P MSI neo here with my p4 and the NX6800 working ) it's like saying goodbye to an old friend that has been by my side since P4 times.
    I'll buy msi products in US , or in another country maybe , but never MORE in portugal.
    This is not cause of the shops , I recommend everyone to buy in the shops listed !!
    In fact most of the portuguese shops tried to help me find msi support ( even though they weren't the stored that sold me the card ).
    I really don't want ppl to get this mixed up, the problem here is MSI not acknowledging a problem that is simple to fix, having a non-existant email on their webpage as support for over 4 months and the fact that as a consumer I was forced to jump trough loops to actually contact MSI itself !
    Every portuguese shop I contacted was super nice and really helpful pointing me to the new msi email
    And actually the fix ( hot needle fix forum post link ) came from a shop reply.
    US support was always super nice and helpful !
    I was forced to fix my fan with the help of users.
    If right now my MSI gpu is working is thanks to guru3d and hardwareoc and simillar forums ( thanks to everyone that posted Twin Frozn fixes , this may not mean much , but really .. thanks for helping me out ! )
    MSI didn't help or even try to help me , I had to go out of my way to get help , and I never did.
    I know some of those stores , they have great prices , but if I buy anything in portugal I'll buy other brands for obvious reasons. ( it was actually one of those shops that helped me pinpoint the "real" msi email )
    I am a customer , I should be treated as such , I was joked and pushed around emails , found emails that don't even exist , I was ignored and left looking at a card going dead.
    Maybe for some of you it's easy , you just buy another one .... and maybe that's the custommer MSI wants. But that's not me.
    Pointing me to places to buy MORE is almost insulting at this point. I wont buy more ... I would be stupid of I did.
    I just hope some other person that has MSI and is having this problem with Twin Frozn fans ( that msi refuses to acknowledge as THEIR problem !! ) can fix them themselves or take some info from my posts and others to at least understand what is happening.
    From my pov , the fan eventually has some sort of lubrication problem , and due to that it starts to wobble , after that the coils heat up to a point it wobbles even more.
    Due to the high temps the fan either "looses" enough to dump all the lubing out.
    At some point the fan will heat up so much the plastic IS REALLY hot to the touch and fells that it can be actually moldable ( so I assume this is really bad )
    This leads to the start-stop problem , the fan tries to kick itself on , but just makes things worse.
    This leads to a fan that fails in 2-3 years.
    MSI should either had a way to put oil in the fan OR just start to be ready to replace them.
    The fact that IS an ebay market for Twin Frzn fans is just flabbergasting .
    I wish I had a better view on this , but seriously looking at this thread,  and seeing all the steps I have done , to find there are others like me that have a failing fan and that the ones that aren't ignored like me have to RMA a card for a simple fan doesn't give me any sort of confidence in this brand.
    MSI has one of the best gpu coolers  , honestly it's so god that after all this mess I stand as a testimony for it being one of the BEST gpu coolers around ! All my MSI products so far have been great ... but this experience was just ... weird ..
    I wish MSI would contact the ppl that are in my position and help them , it's just a fan  , it's an easy fix and it's easy to replace.
    There are lots of ppl right now with fans starting to fail , just take their card , replace the fan and send them back , and MSI will have happy customers , HAPPY cause the brand CARED !
    I'm only 1 client , MSI hardly "fells" me leaving ... I really like MSI ... so I wish this won't ever happen again to no one !
    I have been ignored in mailing for TDR problems , after that about the 12h+ card artifacting being fixed with cold boot ( I assume this was an nvidia problem )
    After using certain drivers that didn't TDR my card ( I have enough PSU for it so ... it's not the PSU ) and having been 2 years finding my own "solutions" to problems ... being ignored and just struggling to get help from MSI for a stupid FAN a cheap part and being hard just to contact them to get no answer .... and getting help from other users while MSI ignores me ? ... I'm thinking on leaving the brand ...
    The fans are now working 100% , I'll post info when and if they fail ( if I see my "fix" stopped working ) .
    It has now been a long time since 2011 and my first reports , and its been almost 6 months since I contacted msi about the portuguese email listed not existing.
    The email is still there , that non-existent email is STILL listen in MSI website RIGHT NOW after me being emailing them about it for 4+ months ,as a customer,  I can only assume they either ignore people , or they have a terrible communications internally .
    Again after all this mess , I would be kinda stupid to support or try to buy another product from this brand , MSI support was always great and was the main reason I bought msi products, all this posts are from a person that was truly SHOCKED in everything that is happening and the feeling that no one cared.

  • Who needs apple to make the bezels for the macbook pro? Lets get together and tell apple they must! It is a design flaw.

    I love my pro. I paid 2700. for it 4 years ago. I did that because I know they are meant to last. I could have purchased a regular laptop but they don't last. Until recently I was ecstatic with it. Then one day I opened it up and my screen seemed really floppy. I didn't pay much attention. Then I noticed there were two cracks on the bezel toward the bottom of the screen. It is where the stress point lies from opening and closing. A very important location. I have read up on this, it is definitely a design flaw. I know the bezels are only work 10-15 dollars if produced. But because of the lack of availability of them they sell for 80 and up. I went to an Apple store with my friend. She purchased an IPAD 3 months ago, it fell out of her car, and the screen broke. Strangely enough, they replaced her IPAD when clearly it was customer fault, although she maintained it was a weak point. Me? The genius looked at mine and said I would need a new screen and it would be 700. Then another solution for 300. I asked why they couldn't just order a bezel. He said they don't make them. Apple does not make computer parts for their own computer? Unfortunately they gave me the rude runaround (Sherman Oaks,Ca manager Gabe Nava) and treated me like I was being unreasonable when I pointed out it was a design flaw with Apple!. Now i have a computer that could last a good 2-3 more years, but with this flaw the life will be shortened. Apple is this how u treat the customers that purchase you most expensive product versus the one that purchases the low/med price product? Let me know pro owners.....lets demand apple make these bezels. They should be replaced for free, but if it were available for 15. and then 50 labor...that I can live with. The best I could get outta Gabe was 150.00 and they keep my computer for a week! I live 120 miles away from the nearest store. I know your out there folks....lets make Apple make this right.

    There are online Mac reaper shops that will fix your bezel, it's nothing really.

  • Slow attachments - imap design flaw or poor Sun implementation?

    I struggled with very slow downloads of email attachments until I found another article on this website which said to set the fetchsize property to something bigger than the default of 16k. I set mine to 256k and I was able to approach 200kb/sec download speeds of attachments from my imap server.
    I looked at the code and read the imap RFC briefly, and it appears that you can fetch the message in chunks and I think that's what the sun implementation is doing. But if you have to turn around a TCP connection all the time you will see major performance hits, just as we're seeing. Bumping up the size to 256k improves the situation but it's still a lot slower than I would expect, plus the sun code seems to allocate and then free 256k buffers on a regular basis as a result of this. That's probably OK since this is the client side of the equation, but my question is, Does it have to be done this way?
    Why, for example, isn't it possible just to request the entire attachment (or message body) in one go? My interface to it is an input stream, why does it have to be broken up into little pieces? Is it just a side-effect of the sun implementation, with its request/response objects?
    I was thinking I'll turn off the partialfetch boolean (not really knowing what that means) and see if that helps, but I am worried that the Sun implementation might just allocate a big array and load the whole attachment into it.
    Meanwhile, at first I thought it was a poor base 64 decoder that might be at fault, but should have know it wasn't that because my CPU was not pegged. Still, I decided to rewrite it in what I think is a much simpler and hopefully faster approach. Would there be any interest in seeing the code?

    Thanks for the reply.
    I think what your answer means is, It's an imap design flaw. And it's because the data and the command connection are one in the same, unlike FTP, which had separate channels.
    Isn't there something called pipelining with HTTP/1.1 where you can request the next piece before you finish receiving the current one? Would something like that work? It would require that the server has a thread for reading and one for writing, and the application would have to risk reading ahead a little bit. The thing to be avoided is the complete and utter stopping of the connection while the client turns around to ask for the next part.
    I don't know what I am talking about. Can you tell?

  • Is there a way to create albums on iPad 2 without connecting to a computer? I heard the iPad 1 did that? It's rather stupid that they don't have that function built in.

    Is there a way to create albums on iPad 2 without connecting to a computer? I heard the iPad 1 did that? It's rather stupid that they don't have that function built in.

    If you are referring to photo albums no you can't create them on the iPad with the current iOS software. You could not do it on the iPad original either as stated above.
    You can purchase third party apps that allow you to do so. One app that I know of is called Photo-Sort. I am sure there are others available in the app store if you care to search.

  • Design flaw in Macbook Pro late 2013?

    Hi,
    Looks like Macbook Pro late 2013 has a weakness, due to a design flaw. Let me explain:
    My Macbook Pro late 2013 (13inch, Model: A1502) developed a dent (see attachment) and an Apple Store (Genius Bar) technician told me that this is a result of "excessive pressure" on the bottom case. He also mentioned that because the case is made of soft aluminium and it is only supported around the border (about where the screws are located), any "excessive" pressure in the middle may result into the aluminum case being damaged by the internal components; in this case  the damage appears to have been caused by an internal bracket.
    There is no sign of the bottom case being pushed inwards, there hasn't been any accident and I haven't stepped, or sat on, or otherwise mistreated my laptop, so I very surprised! Most of the time, it's sitting flat on a desk and only carried insider a padded pouch, inside a laptop-grade (padded) backpack! As you'll notice in the photo (and I can provide more photos, if needed), there is absolutely no other sign of damage, the curves look perfect, and the back plate is flat.
    This is just a cosmetic damage and replacing the bottom case is the obvious solution but I still need to better understand the circumstances; I need to understand what went wrong and, if possible, how to prevent this from happening in the future .
    I visited iFix it web site and carefully looked at the internals of the laptop, here:
    https://www.ifixit.com/Teardown/MacBook+Pro+13-Inch+Retina+Display+Late+2013+Tea rdown/18695
    It looks like the bottom base is only supported around its border. The middle of the bottom case has no backing to support it. While Apple could have designed a support structure around the battery cells and over the motherboard (logic board) and the back case, there is no support structure at all. Hence, pressing on the back of the laptop uniformly (e.g. while in a loaded backpack) will probably result to the back case being pushed inwards and, while aluminium does have some degree of elasticity, it can get damaged when hitting on a sharp object, such as an internal bracket. Hence, I guess the Apple technician is right, this is what probably happened to my laptop and I think this may have happened only in my backpack. But, how “excessive” can the pressure be on a Macbook Pro inside a high-quality, padded backpack?
    If there are other MBPr users who have experienced this problem under normal everyday use, i.e. not due to an accident, could you please let me know?
    I'd be grateful if Apple:
    * Looked into this and provided a workaround, e.g. a more durable bottom case.
    * Considered replacing our damaged cases for free.
    * Published some numbers, to inform prospective customers about the durability of the laptop's case, e.g. in N/cm^2
    * Took our experience into consideration when designing their new laptops.
    Kind regards.

    " I need to understand what went wrong and, if possible, how to prevent this from happening in the future"
    So what's underneath the area w/ the "blister"?
    "It looks like the bottom base is only supported around its border. The middle of the bottom case has no backing to support it."
    That's pretty much been the case w/ every MBP I've ever had apart. Nothing past 2012 however.
    " While Apple could have designed a support structure around the battery cells and over the motherboard (logic board) and the back case, there is no support structure at all"
    In earlier versions of the MBP there is a "separator" between two areas of the upper case but it doesn't supply any support to the bottom case.
    So here's my take on this; Apple has made these MBPs thinner and thinner. In the MBPs I've taken apart 2008 - 2012. In the 2010 I have here the bottom case is very thick and judging by tapping on it is definitely tempered (or heat hardened or stress hardened). I don't have the proper caliper but the edge reads .044 Inch.
    There have been other issues on these communities that relate to the thinness of the top or the bottom cases in these newer machines.
    Never seen a newer machine but my feeling is judging by the issues seen around here is that the materials are much thinner and probably not as hardened or tempered.
    " how “excessive” can the pressure be on a Macbook Pro inside a high-quality, padded backpack?"
    To help prevent this from happening again and if this were my MBP I would use/make a hardened case just for the laptop. Say two sheets of 1/4" hardboard w/ a 1/4" separator of  high density foam. Wait I'm describing a high quality laptop case.
    As Ogelthorpe says, backpacks are not the most delicate way of transporting a laptop. I've seen damage worse than this to laptops, iPads, iPhones, Kindles etc. Especially at the school where I was the main tech. I would say: "What happened to this?" and the kid would say: "I dunno it was just in my backpack".
    I've watched backpacks fall from shelves, get stuck in lockers and get smashed into each other in the hallway.
    I'm sure you're much more delicate w/ your MBP but as the saying goes ".... happenes!"

  • IPad will not connect to my Torch 9850 hotspot

    Before upgrading to iOS6, my iPad would connect hit and miss to my 9850 hotspot connection.  Had to play with it a lot to get it to connect sometimes.  Since upgrading to iOS6, my iPad has not connected to my 9850 hotspot since.  My hotspot does appear to connect to all other devices (several laptops, couple of android phones, etc.).  It just will not connect to my iPad.  I went to the Apple Store and found that their iPad behaved the same.  What was odd was that we did get some connections to my 9850 hotspot inside the Apple Store, but not outside the store, in the mall, in the car, etc.
    This appears to be very strange.  I would like to blame all this on the iPad, but I am wondering if I really can.  Has anyone else had any problems connecting their 9850 hotspot to their iPad, especially since upgrading to iOS6?
    For reference, I am running BB OS v7.1.1737.  I have restored my iPad to factory and retested, and not long ago, I completely restored my 9850 using Desktop Software, after the over the air upgrade flaked out.
    Any suggestions would be appreciated.
    Thank you all...

    Try a reset on both devices. Press & hold the Power and Home buttons simultaneously, ignoring the red power off slider, until the Apple logo appears. Then release both buttons. This should not affect any content on the iPad, it is similar to rebooting your computer.

  • Bug or Design Flaw?: Multiclip

    I'll put headings on this posting because it's gonna be long and you may want to skip parts.
    *Executive Summary*
    Multiclips do not retain modifications. So far I've tried adding markers and adjusting levels to a multiclip in the Viewer and after switching angles and switching back, the markers disappear, the levels revert to default.
    *What I'm Attempting*
    I've got hours of two-camera interviews. Cam A is subject, Cam B is host. Clips are several questions/minutes long. I spent a day and a half syncing and multiclipping and then was ready to screen and pull selects. Or so I thought.
    _Approach 1._ My thinking was the most logical workflow would be to watch the interviews then subclip bits I like. We have neither time nor budget for transcripts nor the man-hours to read and highlight them. And even if we did, I'd still need to isolate those parts.
    It turns out +you can't subclip multiclips+. Modify>Make Sublcip is grayed out and if you try to subclip by extending a marker and then making a subclip from that you get a new clip with a length identical to the original full clip, but with the name of the marker appended to the head of its original name and the original clip also now has this modified name and there seems to be no way of changing that name back.
    Still with me?
    _Approach 2_. OK, so I'll put markers where I find a sound bite I like, name them by subject matter and then, at least, I'll be able to find my selects in my Interviews bin by turning down the disclosure triangles next to the relevant clips. Not as good a solution, but it's what I've got.
    Not.
    +Multiclips do not retain modifications.+ Put a multiclip in your viewer, apply a marker (or adjust audio level), play, switch angles, play, switch back. Your marker (or level adjustment) is gone. They're just gone.
    *Corporate Response*
    I got on with Apple Care Enterprise. My tech guy reproduced my problem exactly. He then put me on hold and went to an upper level tech. When he came back he told me that's the way it's supposed to work. Multiclips have a sync relationship established by the mere fact that they are multiclips so markers are superfluous. I told him I thought markers served several purposes and he started to get a little testy with me. I laughed a little (not derisively, I swear), said thanks and he hung up without even saying goodbye. I was hurt.
    *Why I Care*
    I've got hours of these two-camera interviews and no script. I need to find what I like before I can build it into a show. I need to have access to both cameras as I screen because I can't hear the host on the subject's mic nor vice versa.
    *Less Than Satisfying Workaround*
    Here's the best I've got so far. I make a sequence out of each multiclipped interview, I then mark in and out points when I find a bit I like and I make a sublclip (sub-sequence, really) of it. Let's say I make a 10 second sub-sequence of a soundbite I like. When I'm ready to work with it I drag it to the Viewer and I have a fullscreen image of either the host or the subject. I'm now into the cutting and I know precisely which part of this subclip I want. I mark an in and an out, I cut it into my show, I'm good. And if I want the host and the subject is showing in the Viewer I simply hit SHIFT 1 or SHIFT 2 to get the other angle.
    Here's the downside of this process (besides the extra steps). If I do choose to switch angles in the Viewer, the Viewer reverts to a copy of the original full-length multiclip with a Media Limit set at the In point. If, now that I'm cutting, I find I want to include the host's question with this response I can't without another workaround.
    How many workarounds does it take to screw in a light bulb?
    *If You've Made it This Far and Have a Better Solution I Would Be So Grateful*
    And don't think I'm just looking for problems; this is going to be a huge issue for me on this project.
    Rant
    More and more often I'm finding FCP simply isn't designed for long-form editing, especially long-form documentary where organization, searchability, flexibility and general versatility are essential... No, at best, I've only got one person still with me. No sense in ticking you off too.

    I'm sorry. I didn't mean to raise such ire. Let me respond briefly in turn.
    Zebulun wrote, "How would you go about this if you were in a linear suite with tape machines and a switcher? Lotsa logging."
    I didn't come from tape editing, but rather film editing where you could pull selects. Then for most of the past 15 years I've been cutting on Avid products that work in the manner to which I've become accustomed. I could group then subclip or add locators (markers in FCP) that would not disappear. I've come to realize in FCP I have to change (not lower, simply change) my expectations and my post was in pursuit of direction.
    "...who said editing was easy?" Certainly not me, but any editor worth his or her salt finds ways to eliminate pointless impediments.
    +Patrick Sheffield+, your posting was very helpful and the link to your other posting was so good I've already passed it on. I will say that a long stringout of preferred soundbites, while I may resort to it, is hardly as manageable (for me, for me, we all have our own approach) as a nice bin where every subclip is named by its particular subject. Still that may well be the way I go.
    +David Bogle+: "It's not even a design flaw. But you knew that..." Well then why does it allow me to apply markers and change audio levels if it isn't going to maintain those modifications? I hate to believe after two feature-length and several shorter projects on FCP I still don't understand its fundamentals to such a degree. But perhaps I don't.
    " You say you don't have time or money to do this properly so you appear to be attempting to blame the software product you have chosen as your editing platform."
    Who said there's one proper way? Jeez. I came on to this project as editor and post-producer after a lot of key decisions were made and most of the money spent. I am trying to view the material for the first time and pull what appeals to me as I go. I've reread my original post and, with the possible exception of my rant it just didn't seem harsh enough for this sort of response; I was pointing out something that appeared to not be working or which I didn't understand and looking for a solution. Isn't that what this site is for?
    "I decide what I need to tell the story and then I work on it. That is, I'd select the sound bites and then figure out how to edit the multiclips later"
    Perhaps I wasn't clear. I can't tell what the host is saying while watching the subjects camera nor vice versa. And both sides remarks are important. I had no say over how they shot this show so I have to live with that. This show will be almost entirely a series of dialogues between the host and various other people. And it is part of my job on this project to find the interesting conversations and mold them in to something worthwhile. Yes, I can watch the host's camera until the subject speaks then load the subject's clip and listen to that until the host speaks again and then go back to his clip. I was hoping for something a little more elegant.
    "...this is easily corrected by cutting and pasting the tracks together and merging the new clip's tracks or nesting and exporting."
    Thanks David, this is what I will probably resort to. I am sorry if I offended you or anyone else who replied or merely read my original post. I have no desire to get into one of those 'FCP vs. Avid' dialogues that are so common on these sites. Avid is blowing their market share, my clients and prospective clients are moving to FCP and it is on me to learn to love this application. I am in no way out to alienate those who would guide me.
    Regretfully,
    Martin
