What are the symptoms of the  capacitor freezing problem?

I'm concerned that the freezing problems of my eMac that I've posted about on earlier threads results from a bad capacitor. Are there specific symptoms of that problem that would indicate my eMac should be checked by Apple? My computer falls within the range of serial numbers where this could be the issue.

The Apple warrantee extension program only refers to video and power problems, not freezing. The most sure-fire way to check if you have bad caps is to open the access door at the back of your eMac and look at the logic board next to the RAM slots. There are two little objects that look like 1/4 of a AA battery. (Googling "capacitor plague" should get you some pictures of capacitors if you're not sure what to look for.) If the top of either or both of them is cracked, swollen or leaking a discharge you know for sure that you have bad capacitors and Apple should have no problem fixing things for you. If you don't see any of those things, it might still mean that you have bad caps but they haven't shown it yet.
If you do plan to open your eMac, it's a good idea to put a towel on the desk so that you can avoid scratching the screen. It makes it more secure, too, and no doubt more comfy for your eMac.

  • I´ve bought the new IPad3, what a disappointment the 3G does not work, no Internet available, APPLE what are you doing for the all the people in Germany who bought the new IPad3? I´m still an Apple fan, all my products are from Apple but I need a solution

    I have been waiting since months for the new IPad4G 64 Gbt. ON recommendation of Apple Support I have changed my IPad 4G last week in the hope that something was wrong with the firts one I bought.
    The one I have now has the same problems. WiFi is working however 4G not at all. Apple what can I do? What are you doing for the thausands of German Apple fans who have bought a IPad4G and can not use it. We need a solution NOW. I´m working with this tool and need to be able to rely on it.
    Thanks for a feed back.

    It would be advisable for Apple to react officially on it. € 799, - for something that doesn´t function is no fun :-((
    Isn't replacing your iPad Apple "officially" acting on it?

  • What are tools used by the xi/pi system ,to bug the errrors

    hi gurus,
    what are tools used by the xi/pi system ,to bug the errrors.
    regards,
    subba reddy

    For all kind of errors the only tool available which bugs or say alerts for the error is Alert Management.
    Alerts are messages which can be raised in case of failure.
    Alerts - used for system errors, u can send a mail or msg whenever there is any failure. alert configuration can be done in t-code - ALERTCATDEF.
    Alert Categrory can be defined in transaction ALRTCATDEF on abap stack. we can assign receipients to every alert category which specifies who will receive alert in case of error.
    Alert rules can be defined in RWB.
    for configuring alerts u need follwing roles first for defining or creating alertcategory
    the roles reuired to access the RWB are:
    1. SAP_XI_RWB_SERV_USER
    2. SAP_XI_RWB_SERV_USER_MAIN
    The roles for the Alert Management are:
    1. SAP_ALM_ADMINISTRATOR
    2. SAP_ALM_CUSTOMIZER
    3. SAP_BC_ALM_ALERT_USER
    Once this is done
    alert category is defined and then tested
    For Alert please see
    The specified item was not found.

    If the files are already there, they'll never be overwritten when you visit a
    new site, would they ? That's how the cache works :-)

  • What are payment options for the upgrade?

    I was wondering if I can buy the 2.0 upgrade for the $9.95 on the iTunes store with a iTunes gift card? Or will I need to use a credit card for it?

    I think is a bunch of bull you have to pay for the update iphone users dont. And before you say it they pay monthly to AT&T not apple.
    You really need to do your research on this subject.
    I software is free to iPhone users NOT because of the contracts that people have with AT&T.
    It is free because Apple decided to account for the iPhone (and Apple TV) differently.
    When you pay your $400 for the iPhone they do not recognise the full $400 as a sale.
    What they do (and this has been very clearly stated by Apple), is take 1/24 of the $400 each month.
    This is not money from AT&T is is the money that was paid for the phone.
    Now because in effect Apple are not taking the revenue and profit for the full phone at point of sale and instead only take a % every month the buyer is paying for the phone over the 24 month period.
    Therefore Apple can and will give free software updates because in effect the product sold is not complete and can take money as they add features.
    This complicated accounting method was caused by the EXON issues and the Sabane Oxley laws that resulted from that case.
    If you would like to know more, so that you understand rather than rant, you can read more here in an excellent article that explains it in more detail :-
    http://www.appleinsider.com/articles/08/06/25/thehidden_financial_impact_of_applesiphone.html
    The iPod touch on the other hand is accounted for like all other products, all revenue / profit taken at time of sale. If Apple gave the software Upgrades (not bug fixes as they are free) away for free they would be breaking the law as it would deprive shareholders of potential revenue that should have been charged for adding features to a product that has been already sold. That is why we ahd to pay for the iMac Airport 'N' drivers as well.

  • What are major differences between the T5 and the T5i

    What are the major differences between the T5 and the T5i?

    Hey everyone!
    I just wanted to step in (which is not normal) to say something that most people overlook is that the EOS Rebel T5i has a self-cleaning sensor where the EOS Rebel T5 does NOT; also, the T5i can use an IR Remote (like the RC-6), and the T5 can only use cable releases. These are minor things until you need them! 
    I hope those two little things help!

  • What are your opinion on the new mac pro

    I feel while radical its too limiting thereby loosing fuctionality. But I also knw how the iSheeps would follow their iSheperd blindly. There making this kind of thunderbolt for everything the norm. I also know that the PC companies brought this on themselves they failed to innovate followed intel and nvidia to blindly with there xeons and quadro. The 3 major pc makers market professional workstations that you would probaly sell ur kidney to get one we have the z820 while very powerful its just 2 xpensive. Let's take for example the imac is the best bang for d buck most beautiful all in one if hp had used say a normal 3770k and a gtx 680m 4gb dat would have brought the price of the z1 down drastically. Let's say d average joe wants to be an editor, compositor, colorist. if u goole pc workstations hp z820 and dell T7600 would pop up but they are dam so xpensive hp consumer PCs are garbage. If there is onething apple knows the average pro does not want to be bothered with specs. I think the pc industry brought this on themselves. Wat of the smaller custom builder they focused so much on gaming big megatron design like cases with all the talk of FPS is every thing. My only prayer is that asus, msi gigabyte should stand up aganist apple and start releasing sexier designs, unless I fear even adobe is not safe cos most editors would gradually drfit back to FCPX sad wen inferior products triumphs a superior one. Pls drop ur thoughts also ur opnions as editors in your location the general trend. I hate to be locked in a garden where I am told this is what I need. I love choices.

    The 2 biggest problems with the new Mac Pro are the complete reliance on Thunderbolt for expansion and the Proprietary GPU modules. What happens when those Fire Pro cards are EOL and new GPU's are available. Will Apple go to any of the GPU manufacturers and get newer modules manufactured. Considering the applications that are moving to GPU processing, that was really a very bad idea simply because of the Minimum order quantity Apple will have to make to run another module. Apple will not be able to pull from the general video card supply which means they will be solely responsible for any production numbers required to manufacture to begin with. I personally expect this to be a major limitation as time goes on.
    The complete reliance on Thunderbolt for expansion really was bad idea and not ready for prime time. TB2 has the total bandwidth of a PCI-E Gen 2 5x. That is the entire pipe available to pump any video output data, high performance storage, I/O devices, and any number of devices available as time goes on especially video cards. Those trying to GPU process through that pipe are going to find that latency is way to much a problem to get that done. If Lightpeak was out and had the bandwidth of PCi-E Gen 2 or Gen 3 16X then I would say great. There is just to small a pipe and to much device moderation at the TB controller to do this now. The major problem that will develop from this later is when Lightpeak is out for the PC and devices start moving there. Where will Apple be with the Mac Pro when it's entire expansion is legacy in 1 to 2 years. As a final note Thunderbolt 2 is just Thunderbolt 1 with 1 bidirectional channel in stead of 2 unidirectional. This is not a major improvement over the original.
    The final consideration though not a major problem yet is the limit to 6 Core Xeons. This is likely due to the heat the 8 Core Xeons generate combined with a centralized cooling design. One of the major reasons to get a Dual Xeon is the 8 Core CPU options. Without that then there really is far less reason to get a Dual Xeon over a single 6 core and eventually 8 core workstation. This is a sacrifice that will reveal more later than now.
    Considering the Mac Pro is meant to be the flagship platform for Apple's Pro market, there are really way to many limitations on this one to compete with the PC equivalents. There is only so much OSX will add to any system.

  • What are BEST settings for the WEB?

    Hello, I have a short in RED Hd 1920/1080 finished on FCP 6. I made a QT and then used compressor to make a 800mbps Quicktime for the web, deinterlaced and checked BETTER tab, others stayed with regular.
    I also made one through FCP into a QT in 640/480 which is size I need.
    On the web it looks clear and plays fine. Problem is when there is motion or
    lots of movement, it stops and goes, jitters like ****, not smooth all.
    What settings are best to make it SMOOOTH, just like when watching it on computer or as best. I know you got much bigger things to talk about but if you know please let me know.
    H.264, Mpeg4 or Sorenson ect...just looking for smooth as can get it for playing on web.
    THANKS.

    800mbps Quicktime for the web,< </div>
    The compression is reducing the number of pixels being shown in order to maintain the bitrate. So rapid motion, which requires nearly all of the pixels to be redrawn, causes things to stutter.
    Compression is really, really hard to do. Really.

  • What are safe cleaners for the oleophobic screen?

    I understand that Apple has said not to use solvents, ammonia, abrasives or basically anything other than water on the 3gs screen. I was wondering what a cleaner based on a very diluted glycolic acid might do to the screen. I have a screen cleaner like this, and before using it was wondering how easily the new screen damages. I have not yet found any thread that explains how sensitive the oleophobic coating is, nor one that explains the chemical reactions that might happen with the coating. Calling any chemists, or anyone that has experience with this sort of thing. Thanks in advance, any input would be appreciated.

    According to the iPhone 3GS User Guide, page 45:
    http://manuals.info.apple.com/enUS/iPhone_UserGuide.pdf
    Ignore this information at your own peril. If you were going to use an acid-based cleaner, I'm not sure why you wouldn't just use a weak solution of vinegar. If you are going to destroy the screen, why spend a lot of money?

  • What are some uses for the aggregate object and definition file?

    Can anyone share some examples for using the aggregate object in a Lookout process file? I've spent only a little bit of time with it, but I can't see how it provides any useful functionality. I guess I'm open to suggestions--thanks in advance! JT
    John T. Sampson

    If you want to reuse code in a modular sence than the Aggregate object will work. Although it works best to start the development with the intent to reuse that segment of code.
    Look at the Sequencer Object Example from the Developer Zone. Follow the README file to copy all files into the Lookout/Examples folder. The Help_Template is an Aggregate process that was used many times in different examples for the web. The state file, .l4t, holds the text that gives further details on the development of the example. The Sequencer process has an Aggregate object used in it to open the Help_template.
