Power adapter issue! Please help!

Can someone please tell me where can i find schematic of connector (connector from power supply to Powerbook)! My power adapter is working fine, but the connector is broken, so i just want to replace it, and i don`t know pin assignment! In the connector i have found small electronic board on which are contacts labeled with R, T, S and G. Can someone tell me how to fix this problem! Thanks
Powerbook G4 15"    

I would like to experience some of apple's generosity! I just shelled out 400$ for the world wide apple care plan, only to find out it doesnt really cover me. To get my adapter replaced under this plan, I have to turn in my old adapter and wait 'several weeks' for the new one to arrive, in the meantime I have 1 minute left on my battery and a pile of work to finish.
Interesting to note that the apple store here in Germany has the power adapters in stock and are more than willing to sell me one, only apple wont let them replace my adapter on the spot. Outside the USA, it is optional for each shop to honor tha apple care agreement, according to the Apple phone representative - gee wish they would put that in their sales pitch. Needless to say all the shops I have contacted 'opt out' and the only service center in the city, said I need to wait 'several weeks' for a new one! The new adapter is 100$ US , talk about a rip off, and there is nothing to do except pay.
Over 300 complaints have been registered under this product in the Buy section of the website. Mine started sparking and actually started to burn my sheets - I was woken up by the odour.
I have lodged a complaint with at: https://www.cpsc.gov/incident.html (part of the recalls.gov website) I have also written to consumer reports and other agencies as well. I urge others to do the same, if not Apple will continue to sell this product.
I am upset over the adapter, over the fraudulant and shady wording of their 'worldwide' applecare plan - what person travelling for business can wait several weeks for a new part? - for the amount of money I have to dish out on a monopolised product, where I have no choices or alternatives. I had an apple laptop back in the 90s, and the power adapter gave out in the exact same place - I think that apple engineers these things to break after a set time, and knowing they are laptops, people do not have the time to wait for a new one so dish out the 80$

  • Problem with Power Adapter. Please Help!

    So, I recently noticed that when I try to use my laptop while it's charging up from a low battery it will randomly STOP charging. The annoying phenomenon usually occurs when I play video or surf online as the computer recharges from a low percentage (5%-50%). Now, I should be able to use my computer while it's charging, right?? Also, I discovered that the power adapter gets hot and makes a humming sound that grows louder right before it shuts off. The odd thing is, is that the laptop will charge just fine if I leave it alone. Weird!
    I wouldn't be all worked up about this, but here is what has happened so far:
    I have taken the laptop and power adapter to Apple several times and explained that the orange LED light shuts off and that I have to plug the adapter back into the wall to get it to come back on.
    So far, the people at Apple have:
    1) replaced the first power adapter (that did not work, so I went back)
    2) gave me another power adapter (that also did not fix the problem)
    3) actually replaced the battery (also did not solve this problem)
    I don't know what to do because I don't want to look petty over a stupid problem. However, I have the warranty and this problem is becoming VERY annoying.
    Any ideas or similar situations?
    Thanks,
    Aaron

  • Mid 2010 15" MBP i5 A1286 POWER ISSUE-PLEASE HELP-

    The MBP works fine when mains connected but the only issue is every time I take the charger out it shuts down on me!!! So I have checked with a multitester & looks good the only thing i find hard to check for power is the battery itself as its hard to get a good connection, also I took to local Apple store & they checked with a new battery but said its still same issue so the guy disconnected nearly all the connecters off to check if they causing issue & he said now the battery is charging.
    So they still have the laptop to do further tests etc, but I’m not sure what could be the problem hear as maybe there is some component which is bad so the battery’s not charging or what else could be the issue please help & advice as I’m really confused as if it was something to do with the logic board then surely it would not even charge even after checking with the multitester or like Apple genius done by disconnecting other components...
    ANY HELP OR ADVICE WOULD BE HELPFULL,
    THANKS GUYS

    THANKS FOR THE HELP GUYS!!! BEEN AROUND 5 DAYS & NOT ONE PERON HAS HELPED...

  • Alert Mechanism Vs Email Adapter? please help!

    Hi Experts,
           I have requirement where I have to send error info as email. The email has following characteristics:
    1. Content is multi-line.
    2. Data is dynamic.
    3. Content has to be formated. Like header, footer and '---' lines as separaters.
    4. Content could be more than 100 lines.
    5. More than one email content may be consolidated into one.
    6. Content can also be sent in HTML format.
    Is email alert mechanism suitable for this requirement? if yes then How?
    If all of the above can be satisfied by Alert mechanism then what is the use of Email adapter?
    Are there any pros and Cons of using Alert mechanism and Email adapter?
    Please help!
    Thanks
    Gopal

    Hi Gopal,
    Please be specific in your question. Do you want to send an error info as an e-mail when your scenario causes an error or Do you want to send an error log which is generated for any other scenario as an e-mail attachment/Error log’s Content as the body of  a mail. Both these things are possible in SAP XI 3.0.
    1.       We can send an e-mail with multi-line content using E-Mail Adapter.
    2.       We can set Dynamic Data as the e-mail content.
    3.       The Dynamic Content has to be formatted either in Mapping or in Module and then sent to E-mail Adapter. E-Mail Adapter cannot do the formatting.
    4.       Content can be of any number of lines.
    5.       The consolidation should be done in Mapping or in a Module program and the consolidated data should be given to  the adapter.
    6.       Yes Content can also be set in HTML format
    The above said points are possible in SAP XI 3.0’s email adapter. Alert Mechanisms can be used when you want to send an alert on any event occurrence. It has many limitations like the content should be within specified length etc. we cannot use alert mechanism to pick a file and post the content of the file as an Email. Alert mechanism will work only for the alert categories which you have defined.

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

  • Trackpad Issue - Please Help!

    Hi there,
    Hope you can help me out here.
    I've recently purchased a 15" i7 Macbook pro. The machine is but 3 weeks old &, of course, very well looked after.
    A few days ago, the built-in trackpad started behaving eratically. Cursor moving by itself, not responding to touch, clicking and opening things involuntarily. Not good at all. Many users seem to have had this exact same issue.
    These problems seemed to miraculously stop after a few re-boots and possibly a software update? I really couldn't tell you what resolved the problem.
    Unfortunately I now have a totally different problem.
    There is a thin, possibly 8 to 10mm horizontal strip across the centre of the trackpad that no longer responds to touch. If I move my finger from the botom of the trackpad upwards (or vice versa), the cursor will stop momentarily as it passes over the horizontal strip. The buttons are fine and the rest of the trackpad is fine. For the moment, I've increased the cursor acceleration so that I can at least navigate round the screen with a smaller area of the trackpad. USB magic mouse seems to work fine.
    If anyone else has experienced this &/or found a solution for this issue, please help me out here. I have rifled through endless threads about MBP trackpad issues with little success & do not live close to an apple store/genius bar.
    This is a 3 week old machine that cost me a small fortune. To be getting software/hardware issues so early on in it's lifespan is really rather worrying for the future.
    Appreciate your help here.
    J

    I'm not sure what caused this, but I extended my lunch break and drove the machine down to the Westfield apple store. I didn't have an appointment with the Genius Bar but I managed to persuade one of the staff to speak to a technician in the workshop. She came back into the store and told me that they had replacement trackpads and that , considering the machine was only 3 weeks old, the technicians kindly sandwiched the repair into their timetable at zero cost. 2 Hours later, I now have a perfectly functioning trackpad/machine.
    I can't thank them enough.
    My only gripe is that I couldn't speak to a technician to find out what the problem was, how they resolved it or what causes these issues for future reference. Understanding why these problems occur often helps to build your own framework of understanding. Most of the threads i've read about trackpad issues are largely unresolved with people only speculating the problem/solution.
    The initial issue I had with the trackpad's erratic behaviour seemed to be a well known problem that many are associating with a trackpad firmware update. Unless by pure coincidence I had an immediate & major hardware fault after it, which is unlikely, my personal guess is that the two issues were related.

    hi
    I have a datagrid and I am  doing a custom sorting on the grid(by getting data from DB).
    I achieve this by capturing the headerrelease event of datagrid .In thee venthandler I will query from DB and do event.preventdefault to prevent standard grid sorting.
    Now I need to display my own custom ascending/descending arrows in the header.i have created an header renderer for this,
    In the headerrenderer I am lsitening to the headerrelease event of datagrid and in the eventlistener, as per the sortfield, i am trying to make the sort arrow visible/invisible.
    But somehow making the sort arrows visible/invisible is not working.The initial arrow works fine.it is shown the correct column(Name) as done in the init() method.
    The eventhandler is invoked on clicking the column headers and all the alerts are shown.
    Please see the headerrenderer code below and help me.(code is not complete only the relevant part is included)

    used ipod touch, cant reset to DFU,sync or power off.. please help!!

    From your description it appears that the iPod is on like it showing something on the screen. In that case let the battery fully drain. After charging for an hour try a rest restore and other things again.
    If the iPod returns to the same conditions then it is time for an appoitment at the Genious Bar of an Apple store.

  • AC Power Adapter issue with new (refurbished) ibook...

    I just got my refurbished ibook today and went to plug it in and test it, and then wanted to charge the battery on it. At first I thought it wasn't doing anything when I went to turn it on (it made the starting sound but the power button didn't turn on or anything), but then after trying a couple times, I noticed that the black screen had a faint image of an apple on it. I had the screen too far to the front for me to see it clearly (as it's an lcd screen) and later when setting my preferences, I had noticed the brightness was just too dim which I adjusted...
    So the power button never did glow when it was turned on (at least I didn't notice it after I got it booted up). My adapter's plug fits loosely in the socket on the laptop but still glows green, but all the time... Isn't it supposed to glow orange when charging??? Well I was setting up everything and did my power management settings as well, and as I have it set up to show me my battery level on the desktop, I was noticing that it was depleting (at what I would guess is a normal pace for my current settings), it started off around 83% and had gone down to 58% or so after about 1 and a half hours with highest settings basically. But my power adapter was plugged in the whole time... Shouldn't it be using my AC power and not the battery's?
    So I turned it off and now it is sitting there (hopefully charging), but that little green light on the adapter where it plugs into the laptop is just that, still green...
    Does all this mean that there is a problem with the power adapter and its ability to actually charge my laptop? I got this refurbished (from TigrfDirect) with a 1 year warranty (from Apple) so this should be covered, but as I just received the thing today, I really don't want to have to deal with a messed up AC Adapter...
    Also, I haven't even yet checked the battery itself to see what # it is and if it is one of the ones that is part of the recall or not... I would hate to have to do that and not have a working AC Adapter, though of course if the adapter is't working, I can't charge the thing anyways, so I guess I would have to wait another few weeks with dealing with Apple and the warranty issues anyways.
    I looked in the help section and the only suggestion they had for if your battery doesn't charge is to take it out and put it back in and then attach the adapter again. I guess I could do that at the same time I check on the battery's recall status, I just hate opening my computer up as soon as I get it. Also the battery cover is not totally flush with the rest of the case, one corner sticks up a bit, and I think it was a replaced item as it doesn't have the little LED lights that the computer says should be there to tell me how much the battery is charged (unless this is UNDER the cover for some reason, but the cover is bright white compared to the rest of the ibook coloring, so it seems as it was just a basic replacement cover used)...
    Ok, so thanks for any input you might have. I will let people know in a couple hours if the ibook has actually charged at all during that time or not...

    So I did the reset button thing and it didn't do anything at all... If I plug in the power adapter without the battery the laptop will not turn on at all, so I am guessing that it definitely is the adapter and will have to contact Apple to somehow get a new one. Oh great, tomorrow's Friday and isn't this a holiday weekend? Which means it will probably take even longer to get them to send me a replacement adapter... You think that buying a refurbished mac would mean that they would have tested out all the parts/components first before reselling it...
    And so while I was at it, I checked on my battery's model # and serial # and it is one of the ones on the recall list. I think I was right that it had been replaced (now that I know that the battery is part of the back cover) which would probably explain the recall battery as this is one of the older ibooks and should have been one of the lucky ones made before the ones on the list... I did get to see the lights (only 3 though) flash solid green for about 3 seconds when replacing the battery back into the laptop.
    One good thing did come out of this... As I was taking the keyboard out to find the computers serial # (I already filled out my form for the new battery), I was surprised to see an Airport card. Not that it would have surprised me too much in the first place except that it wasn't listed in the details/parts list when I bought the laptop. It was also listed that my laptop had a 10GB hard drive (while the picture on the website showed a 30GB one). The box it came in said 30GB as well, but I just dismissed that. I had went to see how much space I had left on the HD to see that it had 13.99GB and this is after any formatting, and the install of OS 10.2.8 including OS 9.2.2... So a few added bonuses to help make up for the fact that it is NOT is as good shape as I was expecting (or should be to even be sold as a refurb IMO), and the fact that the AC adapter is completely faulty.
    I just hope that I can get a new AC Adapter soon, so that I can at least be able use my laptop with some kind of power until the new replacement battery shows up. This must be some kind of terrible joke. I get the laptop to be able to use it for a few hours and then have it be without ANY kind of power for posibly up to 2 months? I seem to have the worst luck with Macs, which makes it strange as I have never had any problems with all the PC's I have ever used (and I started using computers when I was 4) but I have now had an imac die (possibly the HD), an Apple studio monitor start flashing on the screen possibly due to connector problems, and now this (and all within 2 months). I am almost ready to just give up, but I have spent too much time and money on all this mac stuff (and all for my obsession with OS X) to do it just yet.
    So please tell me macs aren't always this horrible, or else I will have to make up my own commercials where PCs are better because at least they turn on and boot up for more than 1 week (I think I had the imac working for about 5 days total before it would boot with errors).
    Or some kind soul could also mail me a working AC Adapter that would work with my ibook (if you happen to have a spare), so I could get to do more on it other than changing it's settings... I now only have 40% battery life left. I don't think I should even turn it on again as the boot up alone would drain away too much precious juice...

  • !!!Very Urgent-Production Issue -Please help

    Hello IDMers,
    We are facing an issue in production, we updated the AD Process form yesterday. Two fields- Employee Type and Employee ID field in AD User Process form got refreshed for all existing users. Those two fields are empty now for all users.
    But these fields have appropriate value in the Xellerate User Table for all users. Now I need to some how populate the Employee Type and Employee ID field for all employees from User Table to AD Process form.
    for example: Consider an Employee called Peter- His emp type is Full Time and Emp ID is 100; which i have it in OIM User Table, but this user is provisioned with AD and now i will have to update his AD Process form so that these two fields are populated. I need to do this for all users in OIM. I guess the prepop adapter triggers only when the form is created for the first time. Please suggest me some ideas.
    Is there a easy way to do this task?
    What my thinking is, I need to have a scheduled task that basically loops through all users and updates their employee type and id field in AD User Form from Xellerate User Table.
    Please help me with this as it is highly important.
    Thanks again every one for your support all the while.
    Regards,

    hey,
    i was doing lots of migration from one OIM box to another during our last release. I guess something would have gone wrong while doing an import/export from one OIM system to another.
    What I learned was while doing an import the vulnerable object is AD USER (or any resource of OIM) Object (both Process form and process definition), because those are the two objects which you need to import fully no matter how big a change you have done.
    So when you do an import watch out for USER DEFINED FIELDS in the process form because for me the two fields which disappeared were user defined/custom created by me. So make sure you export the latest version;even if you didnt make any changes to them better create a new version copy of the form and then export it.
    Hope that helps.

  • Router/Connectivity issues please help!

    Hello, I'm running Verizon FiOS with the Westell 9100EM Modem/Wireless Router. I just recently upgraded the security settings on this (Upped to WPA2-Personal from WEP, Turned on MAC filtering, and turned off SSID Broadcast). I input all of the wireless devices in my home network (2 laptops, 3 gaming consoles, 1 netbook, 1 desktop w/ wireless card, and 1 wireless printer) into the allowed devices list, and confirmed all of them were able to connect to the home network after turning off the SSID Broadcasting.
    The next morning I awoke to find that nothing could connect wirelessly, so I troubleshot that by just connecting again to the network by entering in the SSID when prompted, and entering in the security key. Went to work and came home to find that once again nothing was connecting wirelessly, and that I was getting "Low connectivity" warnings, and I could not connect to any internet service (browsers, IM programs, Windows Sidebar gadgets, etc.).  In the midst of trying to figure out what was going on, we had a power flicker (gotta love Florida) which reset the modem and things came back on like normal.
    Last night, I come home from work and what do ya' know... it's the same "Low Connectivity" error and symptoms as I just described, I try resetting the modem... nothing. I try resetting the modem and restarting the computer... nothing. Opened a command prompt and ran ipconfig /all and it pulled up an IP Address of 254.204.X.X (the x's are only there because I don't remember the last two octets), and so I checked the properties of the networking device on my computer to see if somehow a static IP had been set up, but it was all still set up to auto-assign everything. So, I started opening up the actual network properties and checked some boxes, changed a setting here and there, but stupidly didn't make any notes about what changes I made, and then the next thing I know the internet just came to life.
    Tonight, once again, I come home from work and school, and the network is pulling the same thing, only this time, I was able to reset the modem/router and it seemed to fix the issue.
    My question is this: Did I mess something up when I turned off SSID Broadcast, turned on WPA2-Personal, and set up MAC filtering? Or is there something wrong with the unit? Or is there something else going on here altogether?
    If anyone could please help me with this, it would really be nice to get my mom off my back. Thanks!

    You don't say what version of windows. I suggest you enable the SSID broadcast and see if that helps. If you are running WPA 2 with AES you are secure enough. The MAC filtering is adding extra overhead that is not necessary. I suggest you get rid of that. Anyone can just as easily spoof the MAC address and anyone can find the SSID if hidden. These are not security measures. WPA2 with AES is.

  • SERIOUS BLACKOUT ISSUES  PLEASE HELP

    my Powerbook G4 is a wonderful machine. i love it dearly. but after upgrading to tiger 10.4.3 my system crashed. i re-installed Tiger 10.4.2 to be safe and have been having strange blackout occurences that happen randomly when i'm typing or surfing or just playing on my computer. the screen goes to sleep mid action, i wake it up, it sleeps again and by the 3rd time completely blacksout. i've also noticed that i don't hear my fan going anymore. could this be an overheating issue? how much does it cost to replace a fan? please help

    I am having a similar problem that started after upgrading 10.4.3 as well. it started with my comuter randomly going to sleep, then it began getting stuck in a mode where it would alternate between sleeping and waking, now the screen just goes black (after a brief glimmer of blue) when I start it up. Sometimes i can see a dim out line of the log in screen. I took it to the apple store and they said to try resetting the power control unit. This worked for a while, but now it does nothing at all.
    Interestingly, I can run from an external monitor with no problems, but this defeats the point of a laptop! The other thing i noticed is that the computer is much more sensitive to vibrations--if i bump my desk it will go to sleep. I tried the suggestions on a previous post-- that this was a track pad issue but installing Sidetrack did not improve the problem.
    Is this a bad logic board?
