Logic board dead?

hello all,
i've recently had some problems with my 12" ibook G4 1.2ghz (late 2004) and i'm wondering if it's a problem with the logic board. i'll walk through what happened:
1. it shut down while on sleep
2. then shut down while i was using it. i realized that it hadn't totally shut down because i could hear the harddrive spinning and the caps/num lock lights still came on, but no shortcuts worked (ie the commandopt+ctrleject shutdown) so i had to hold down power button for 5 seconds.
3. i plugged in an external display at this stage to see if it was just an internal display problem - but nothing came up on external display.
4. i did PMU and PRAM reset and it worked for a couple hours and everything seemed fine. i ran hardware test and everything passed. then the same shut down thing happened, with hardrive still spinning, etc.
5. had troubles starting up, had to do a PMU reset again. but then it kept doing the same shut down. tested with battery or plugged in, same thing.
6. eventually when i'd try to start up the cpu fan would turn on and go nuts but nothing would happen. now i cant get past this stage and i have to remove the power to get the fan to stop.
7. i took out my harddrive and tested it and its fine.
i read a couple other posts that had a similar problem. anyone find a solution? is it the logic board??
thanks for your time, anything is appreciated!
12" ibook G4 1.2 ghz Mac OS X (10.4.8)

Yeah, it's the logic board. It just happened to me and if you follow this link at the bottom, you'll see about a hundred people confirming it. The guy that hosts this page did some great research and found an easy, cheap fix that seems to work for almost everyone. Again, you can read their experiences. The common denominators among all these people are: Your symptoms, happens for no reason (i.e. not dropped or bumped or abused) AND the biggie, all were told by Apple that if it's not under warranty or Apple Care it would be about a $1000 job to repair it with no exceptions (listed on this site at least). They have recently been using the tech support call as a segue into "Why don't you just put that money toward a new MacBook?"
To listen to the sheer number of people reporting the same as you (and me- G4 14" 1.42 Ghz 7 mo.s old) and mentioning to how many of their friends it's happened to, it's hard to believe Apple can keep a straight face and say there is no problem with these models. IMHO, If they did not have the MacBook to try and push off on everyone, they would be doing a recall on all these or risk losing tons of sales on a very popular model. Hope this helps. It's interesting reading at least. Good luck.

Is my logic board dead? I can't see a hard drive

My G4 Powerbook (FW800, 1.25GHz model) stopped booting last week, and showed the question mark folder. I ran disk utility from the Tiger CD, and it doesn't "see" the drive. Same with system profiler. Under ATA it shows my Matshita CD-RW, but no hard disk.
Figuring the hard disk is dead, I replace it with a Hitachi 5K160.
The result is the same - neither disk utility nor system profiler can "see" the drive. I also tried target disk mode, and the firewire host couldn't see it either.
This leads me to suspect the logic board, perhaps specifically the ATA controller. However, this doesn't quite make sense, since if the ATA controlled was dead why would the CD-RW drive work?
There are no jumpers in the new drive (just like the old one), which makes it a master.
thoughts?
thanks.
G4 PowerBook Mac OS X (10.4.8)

i've seen dead drives - clicking, buzzing and not accessible that passed all tests including fsck command.
often tests won't find errors.
if 2 different dirves are not recognized by Disk Utility it's either drives, drive cable (rare but possible) or logic board.
another way to test drives is to put them into FireWire external case (probably can get one for $20) and try to format them that way.
if drives work and boot the machine, it's likely either drive cable or logic board problem.

MacBook Pro does't boot, logic board dead?

Hi there, I have a big problem with my MBP 1,87 Ghz. It doesn't boot anymore, I press on button and fans starts, hd seems to make a little noise too and anything else happen, screen remain black and the white led is on but doesn't blink. Keyboard seems to be off, caps lock and num leds doesn't turn on, USB ports seems to be ok. I've tried changing the RAM but doesn''t helped. Is the logic board that is dead? Help me please!

P.S. I have already tried pram and scm reset.
Anyone can help me??

PowerBook 15" Al not turning on (Logic Board dead)

Hi,
My powerbook has not been turning on since last morning. I went to get it checked at the apple care centre in Bangalore and they tell me its a logic board issue. Now this is something very strange for me. Last night it was working fine and I had just turned my pb off after work. When I tried to start it in the morning it just wouldnt turn on and now they tell me that the logic board had gone kaput. I cant understand how this can happen when there is was off the external power supply.
Has someone been experiencing similar problem of the logic board just dying ?
I bought it in April 2005.

vibhanshu:
I have not seen as many logic board issues with the 15", although if you go to the Search field at the top right of this page and type in logicboard, I am sure you will find you are not the only one.
G3 and G4 iBooks have had much more of an issue, as have the 12" G4 PowerBooks. I am not such what causes it, although I am pretty sure it is not something that you did.
Unfortunately, your computer is not of much use without the logic board, so I guess you'll have to bite the bullet and get it fixed. If you have AppleCare it should not cost you anything; if you don't, I'm not sure what the prices are in Bangalore.
Please do post back with further questions or comments.
Good luck.

Replacing/ fixing the Logic Board yourself

Hi there, I have taken my iBook (dual USB, @ 700MHz, 20 GB HDD) to this Apple Store in Buenos Aires, which I'm pretty sure has a fried Logic Board.
They told me up front that the cost wil be around 700 U$S, and that the warranty will be 90 days. I'm not thrilled at all for the warranty, I expect to be a lot longer after spending all that money!
Anyways, a couple of questions:
1- Is 90 days a regular warranty period, or am I being robbed?
2- Aside from replacing the Logic Board with a new one, is there anything I can do to fix a Logic Board?
(Anything I can solder, for instance; or something like that?)
Thank you very much.
PB 15" @ 1.67 Ghz / 1.5GB RAM / 80 GB HDD Mac OS X (10.4.7) Also a (Logic board) dead 12" dual USB @700 MHz 20 GB HDD

Thanks a lot, Rhonda.
No, the iBook does not show the "classic" Logic Board symptoms, it simply does nothing at all when plugged and the power button is pressed, nothing at all. (Tried with two different batteries, w/o batteries, w/o the extra RAM, w/o the AirPort card... Nothing, in any case)
Left it on the Apple Store, they will open it for 20 U$S and let me know on Thursday what it is going on with it, and see if I accept the charges for the repair.
The problem of getting a MacBook is that if repairing the iBook is expensive, getting a MacBook costs some 2000 U$S down here
I guess if everything goes bad with the local Apple Store here (have to pay 700 + U$S for the job, etc. pretty much what I expect) I'll wait and see if I can send it to DT&T, what they offer is simply amazing, not only the price, but also the 6 months warranty.

Is there a fix for a dead ethernet port besides a new logic board?

My ethernet port went dead on my IMac. I unplugged the ethernet cable and plugged it into my laptop and it worked instantly. I am still able to connect wirelessly. I bought an apple USB to Ethernet converter and plugged it in. It worked for about 3 days and then it went dead. Once again I was able to unplug the ethernet cable, plug it into my laptop and instantly had a connection. Is there a fix for a dead ethernet port besides a new logic board and if not how do I figure out which logic board I need?
Thanks
Step

This problem baffled me. I kept getting the "ethernet cable unplugged" error after testing my cables good. Was abut to write it off as port gone bad when I found this thread.
The YouTube video reference above fixed my problem. (http://www.youtube.com/watch?v=u1P6X87qArs)
Basically go to SETTINGS/NETWORK. Then highlight your ETHERNET port and click the ADVANCED button. From there click the HARDWARE tab.
Set
CONFIGURE to MANUALLY
SPEED to whatever your ethernet speed is, in my case 1000baseT
DUPLEX - FULL DUPLEX, FLOW CONTROL
Leave MTU at Standard
Hit OK.
Then don't forget to hit APPLY. I didn't do this the first couple of times assuming hitting OK applied these settings. You gotta hit APPLY.
In about two seconds, my Ethernet connected again.
I went back and reset it to AUTOMATIC just to test and after doing so got the cable unplugged error again. So I am leaving it on manual and it's working.

(HELP) Dead MacBook Pro.. possibly something to do with the logic board.

I had been noticing my MacBook Pro's performance degrading lately.. for example whenever I dragged a file into a folder it would lag for 5-6 seconds and then copy over. It started to bug me so I guessed that maybe a reinstall would fix the problem. After reinstalling and rebooting, I got no video on the display.. keyboard wouldn't work.. only things that happened was the disc drive made a sound, light came on the font and could hear the HDD spinning a little.
I then took it to the Apple store as thats what Apple told me to do on the phone. So we took the loverly 3 hour drive(there and back) to the closest Apple store just to have the man take it out the back for 2-3 minutes and then come back to say "It's possibly the logic board that is dead".
I am out of warranty by 2-3 months and so he told me I would have to pay £700 or so to repair. As a full-time student I don't have that kind of money.. I don't even have £60. - I find it annoying how they didn't even fully check the problem out.. just a "possibly the logic board".
So what if I manage to click my fingers and have £700 appear right before my very eyes? I pay for the new logic board just to find out thats not really the problem? or maybe have the same thing happen again right after the 90 days that logic board is covered for? meaning I have to fork out another £700.
I am a massive fan of Apple.. I love their products. I have brought so many products of theirs.. now just 2-3 months after my warranty runs out.. I get this. They didn't even say sorry for selling me a faulty product and didn't offer to help out in any way. When I spend £1,299 on something I expect it to last A LOT longer than a year and 3 months.
I need my MacBook Pro very badly for College but now I can't do my work and if I want to do my work, I have to pay £700 for it.
What do I do? Who do I talk to? Is it possible to get it fixed without having to pay that kind of money?
I can't settle for anything less than a Mac. I love the OS way too much and need so many of the apps that are Mac-only. So no way am I going to forget this and buy myself some cheap PC CrapTop.

Unfortunately, if you cannot boot from the disc, it won't be possible to do any diagnostic tests yourself.
It might be worth getting a second opinion. Is there an Apple authorized repair shop anywhere near you? If so, possibly you could take it there and see if they can diagnose it. You may need to pay a small fee for them to do this. But possibly someone might take a little more time with it and be able to give you a definitive diagnosis.
I'm grasping at straws, but you might be able to try resetting the SMC:
http://support.apple.com/kb/HT1411?viewlocale=en_US
I don't know if this would help or not--there are not many things to do when the computer is unresponsive and you can't use the keyboard or a disc.
Unless the problem was reported to Apple while the MBP was still under warranty, I don't think there is any way that Apple would be able to fix it under warranty. Did you ever take it in for any problem under warranty that might relate to its current situation?
I don't know if you might be up for trying to fix it yourself. If you are, here is a site that might be of help:
http://www.ifixit.com/
You have my sympathy--this has to be an exceedingly difficult situation for you. I will continue to think about this, and will post back if anything comes to mind.
Good luck!

Hi i have iMac G5 Power PC with dead logic board,when i turn it on screen is dead. Is it possible to recover data off it by hooking up via firewire to my newer G5 3.06Ghz with IntelCore

Kia ora, hi i have an older (2003 or 4) iMac G5 Power PC 2GHZ - when i turn it on the screen stays dead but the light below screen comes on & i can hear fan (after a few mins on the fan gets noisy).I think the logic board may be dead & can not afford new one & I would like to recover some files & stuff from it and have heard you can recover stuff using a firewire cable so i got cable (firewire 400 to 800) but i am unsure how exactly to do it.
Can anyone out there please explain how i might do it
Thankyou very much
ps my first post on mac forums so hope i got it right

You can remove the hard drive from the iMac and put it in an external enclosure. You could try using Target Disk Mode to transfer data. Click on the blue link to get the instructions on how to transfer the data.

Dead for no apparent reason - logic board AGAIN?

So last night, after I had installed all my software updates and restarted successfully, I decided to pop in a new airport card b/c mine had been giving me trouble (and I wanted to find out whther it was the card or the logic board that was failing)
Well. I found out. The thing successfully shut down without a problem, and replaced the card without a problem, plugged it in. hit the power button. nothing. nothing nothing.
not even a hum or a chatter.
I've been poking through the discussions here, and I understand that this is likely a logic board failure.
I've already had my logic board replaced, twice I think. The funny thing is that my poor 'book worked for 3 yrs. without issue and now it's been failing close to once a year.
I'm kind of at a loss as for what to do, I really can't afford to keep getting it fixed like this! Also, I have two exams this week, and yup, of course I take all of my notes on my laptop. Distressing, to say the least.
Well at least that was cathartic.
ibook G3 Mac OS X (10.4.7) there's no option for 10.4.8.... also, dead.

If it's the recognized logic board failure, it will usually start up at least. You may have to wait overnight for it to start up again. I did on two of my three logic board failures.
You may know that enough Dual USB G3 iBooks suffered from this problem that Apple began the iBook Logic Board Repair Extension Program in January of 2004. Check out the FAQ page and if the symptoms look familiar, give Apple a call. If your iBook qualifies, it's a free fix.
If you are past the three-year time limit, try calling (800) 767-2775 and ask for Customer Relations (NOT Customer Service--they can't help you) and ask them to please make an exception to the three-year limit in your case.
If the answer from Apple is absolutely, positively, "NO!" DT & T Computer Services in Fremont, California offers the cheapest repair I've found. They have a six-month warranty on the repair.
Good luck!

Retrieving info off ibook with dead logic board

our ibook's logic board died, so we bought a new macbook. now we are trying to retrieve stuff off the harddrive of the ibook with firewire.
i followed the steps to use target disk mode, but the ibook starts up with a blue screen and a floating firewire symbol, and nothing shows up on the macbook at all.
the repair guy said nothing was wrong with the hard drive, so why can't i access it?
please help!

jayson,
The C clamp method works for some units because of an open circuit short on the logic board isolated at the video card chip in the lower left hand corner of the unit, about dead center 1.25 inch approx. away from the left/bottom edge of the iBook. By appling pressure to that area the chip is forced back down into the logic board, closing the circuit, and enabling the computer to startup, use the display and not go into kernal panic from a open circuit short. As far as getting data off of the HD, the local tech claimed my HD was erased and there was nothing viewable on it. I took it home, applied some pressure with my my hand and viola all my data, user account etc like nothing had happened...its sad but I am sitting next to my old computer clamped to the table with some cardboard shims for protection. Guess its a desktop now until I get it fixed!

3 times dead logic board and now you are on your own.

My G5 is dead for the 3rd time.
1st time it was fixed at CompUSA. They told me that the logic board was under recall and they fixed it. They told me that they had seen a bunch of these. OK.
2nd time logic board. they open it at apple and say, yup popped capacitors. I call apple to complain, they say you are covered.
3rd time logic board, AGAIN. they will fix it this time.... AND YOU WILL ONLY BE COVER FOR 90DAYS AFTER THIS, IT IS OUT OF WARRANTY NOW.
When you buy a computer that has a know problem and you let them try to correct it, is this how you should be treated? Has any one else been treated like this?
what should I do?

Hi S SQUAT-
Greetings and welcome to the Apple Discussion boards
Miriam offers sage advice. Contact Apple at the number provided and firmly yet politely state your case.
You may also want to research your local consumer protection laws. Often manufacturer's are given three tries to fix the same problem then must provide you with another solution in either a refund or a replacement unit.
On a related note, I have never been impressed with Apple service as provided by CompUSA. Apple will always try to point you to the nearest facility but you do have the option to choose another service provider.

Run the monitor on an iMac with a dead logic board?

Can a Mac mini be used to run the monitor on an iMac with a dead logic board?

Apparently my iMac was just dirty. When the tech tried to start it today it started even though when the tech tried to start it yesterday nothing happened. So no need to fix anything.

New logic board, and new display, but now completely dead.

Hi guys,
I've got an iBook G3, running 10.3.9.
In December 2006, the logic board failed, so I bought a MacBook, because I didn't have time to be offline waiting weeks for Apple to replace the iBook's logic board.
After much badgering, Apple reluctantly replaced the iBook's logic board under the extended warranty program.
While the iBook was with the Apple repair store, they replaced the display for new as well, even though I didn't ask them to, and even though I wasn't charged for it.
I presume that was because the store discovered that the display was duff enough to be replaced under another extended warranty program.
When I got the "repaired" unit home, with a brand new logic board, and a brand new display, I turned it on, and it seemed to be working fine, so I turned it off, and continued to use my MacBook.
A few weeks ago, the second logic board on my MacBook failed (another long horror story entirely), so I began using the iBook for the first time since it had been "repaired" some six months earlier.
Almost immediately, the iBook began exhibiting a major problem, specifically that I'd be typing away, and suddenly the display would go black.
I could just about see the icons and documents on the screen, but the unit was unusable.
So I pulled restarts, full shutdowns, disk utility, zapped the PRAM, etc, all to no avail.
It seemed to be an intermittent problem.
For example, sometimes, from a cold start, the unit would work for two or three hours until the display went black.
Other times, I'd pull a cold start, and it would go straight to the black display.
By chance, I discovered that if I gave the iBook a shake, the display would come back on.
But then it would go black after a second or two.
And then with another shake, it would come back on for a second or two.
And then it would go black after a second or two.
And then with another shake, it would come back on, sometimes for a couple of hours at a time.
So I figured that it must be a cable which, during the installation of the logic board, and/or the new display, wasn't seated correctly by the technician.
I phoned Apple, and told them about it.
They said that because I had reported the issue beyond 90 days since the logic board had been replaced, it was no longer Apple's problem.
I explained to Apple that I hadn't used the iBook for six months, because I had a MacBook.
After much badgering, Apple has agreed to replace the logic board if it's faulty.
However, Apple has refused to replace the NEW display, even if that's also faulty.
Apple is also insisting that I have to pay all the labor charges.
Meanwhile, I've noticed that the iBook is now incredibly hot.
I mean, the MacBook is infamous for running hot, but this "repaired" iBook makes my MacBook feel like a block of ice by comparison.
I don't remember the iBook running so extremely hot before the "repair."
Which has made me notice that during the last few weeks, I've never heard the iBook's fan come on.
I presume that an iBook has a fan ?
Please confirm.
Therefore, another loose cable ?
Today, the display went black again, as usual.
So I gave the iBook a shake.
But this time, nothing happened.
No display.
No fan.
No hard drive spinning.
Just silent and dead.
What do you reckon, guys ?
Duff logic board ?
And/or duff display ?
And/or duff fan ?
And/or duff cabling by the technician ?
As far as I'm concerned, I don't see why I should have to pay for yet another repair, to correct hardware and/or workmanship which was so bad that after only three weeks of ACTUAL use since the "repair", the unit is now completely dead.
All opinions and advice gratefully received.
With thanks and best wishes,

Hi S,
Many thanks for your helpful and swift response.
I agree with you regarding the likelihood that these problems would have surfaced immediately during normal usage, regardless of how much or little time had passed since the repair.
As advised, I will inform Apple Customer Relations UK about the new developments.
Indeed, when I resubmit the iBook, I'll include a print-out of this discussion.
I agree with you about the fan.
Prior to the failure of the first logic board, I ran that iBook for YEARS, without noticing any heat issue.
Indeed, if there had been such incredible heat, then I'd have searched these discussion boards, and reported it to Apple HQ.
Therefore, the astonishing heat is definitely a new development since the "repair."
Consequently, I take on board your comments about the lack of a working fan since the "repair", which I shall also mention to Apple HQ.
As for running the Apple Hardware Test, the unit is completely dead.
The power cable is green, but the unit is now completely silent and black.
I also note your suggestions regarding the cable which connects the display to the rest of the unit, which I shall also mention to Apple HQ.
No repair sheet was ever given to me by the Apple Repair Centre (ARC).
Indeed, no receipt was ever given to me when I delivered the unit to the ARC, nor was any paperwork ever given to me when I collected the unit from the ARC.
However, Apple HQ can see on their screen that the logic board and display were both replaced for new by the ARC.
What else was and wasn't done by the ARC is a mystery.
I'll phone the ARC and ask for copies of any and all paperwork, so that I can submit it all to Apple HQ, which I note is your recommended option, rather than returning the unit to the ARC.
However, the complicating factor is that with the exception of the logic board, it is my understanding that Apple is denying any liability on any part of the "repaired" unit, including the brand new display.
If I understand Apple HQ correctly, they're now saying that all other hardware and labor costs will be mine.
I'm sure I could buy a WORKING second-hand iBook G3 for the same price as a repair, if not cheaper.
Therefore, perhaps I should return the unit to the ARC, and give them the opportunity to correct their previous workmanship, at their OWN cost.
Because as far as I'm concerned, the ARC had two customers during the repair: Apple and the end-user, as evidenced by the fact that the ARC has invoiced its first customer Apple for workmanship which was clearly not up to Apple's own standards, and the ARC has then delivered the unit to its second customer, the end-user.
In addition, regardless of Apple's 90 day warranty on repaired hardware, UK law includes the Sale of Goods Act 1979, and other relevant legislation: http://www.dti.gov.uk/consumers/fact-sheets/page38311.html
Furthermore, if the ARC is completely unhelpful, I could jump all over them, by writing to Apple HQ, with cc's to the UK editions of MacWorld, MacFormat, and MacUser magazines.
As advised, if the unit goes to Apple HQ, I will suggest that the unit is looked at carefully during disassembly, to see if errors were made during the ARC "repair."
I'm always polite when on the phone to Apple, because I love the company so much.
Indeed, even though during the last twelve months, I've been having very bad luck with the iBook, as well as with a MacBook which has exhibited so many problems that Apple has now agreed to replace old for new, I still love my Mac.
And joy, sweet joy, I've just seen on the TNT courier's tracker website, that my replacement MacBook, built by Apple in Singapore, then flown to Arnhem in Germany, then flown to Northampton UK, then delivered to Heathrow UK, left the Heathrow depot 30 minutes ago, for delivery to the customer.
And the sun is shining.
Thank you again for all your kind and wise advice.
With best wishes,

My macbook pro logic board died. I had all my music on an external drive. How do I get my iTunes library, playlists etc. from my dead computer onto my new one?

My logic board died on my old macbook pro. I have a new one, but I want to get my iTunes library off my old hard drive and put it on my new one. I had set up my old MBP to store all my iTunes music on an external drive, so I have the music. The iTunes program was on the old MBP hard drive.How do I essentially recreate my previous iTunes library, playlists, etc on my new laptop?

You will need the iTunes Library.itl file which generally lives in ~/Music/iTunes/. You can recover this from the backups you were making before the HDD died. Otherwise, you cannot recreate the library.

What's wrong with my drive? Dead Drive? ATA controller? Logic Board?

Hi!
I have had a problem with my iBook G4 1.33GHz for a while now. I've tried a few times to fix it and then have given up thinking replacement was the best option. I'll try to be brief but this saga has actually been going on for over 2 years.
The basic problem is that the computer finds the HD intermittently. The problem used to occur after the computer had booted and was on for maybe an hour. A friend of mine removed the drive and had it running in a separate enclosure for a few days. It seemed fine-all disk checkers like Disk Warrior checked it out just fine. He reinstalled the drive and gave me back the computer. Within a few days, it froze like before. Upon restart I just get the question mark folder.
That was almost 2 years ago. I've tried a few different things to see what was the problem but to no avail. Here's what I have tried:
-Booting into target disk mode-the disk does not mount.
-Booting from a CD-even if I hold down the C key, it prompts that this is going to be a new install and when I get to the screen to pick the volume, the HD does not appear.
-Tried the shim trick as indicated at:
http://coreyarnold.org/ibook/?p=20
Some earlier symptoms included video issues so this made sense.
-Took apart yesterday to make sure the drive connected well. It didn't work at first but later booted from hard drive.
-Since it booted, I restarted in Target Disk mode and ran Disk Utility from my iMac. There were some errors but DU was able to fix them all. Restarted iBook no problem.
-Ran Apple Hardware Test overnight in loop mode. After 18 rounds, nothing came up.
-Ran SMART Reporter and got green.
-Thought everything was ok so I ran Software Update. First round went fine. I ran it a second time knowing that some updates can be incremental. Upon downloading, computer froze and since then I am back to square one-no booting.
-Took apart today to see if there was any corrosion on the ATA chip as mentioned in this article:
http://discussions.apple.com/thread.jspa?threadID=2310290&tstart=0
as the thread mentioned a lot of stuff I was experiencing.
-Reassembled after finding nothing.
-Now the computer does not boot whatsoever-it tries to eject disk in optical drive and then nothing else-no sounds, no video, etc.
So what does all of this mean? I thought the earlier indicators were a dying drive but when my friend checked it out and found nothing, we were stumped. He actually suggested the ATA controller. The not wanting to boot from a CD really bothers me. What does that mean? I have never seen that in 20 years of using Macs.
Oh and if it matters, this computer was formerly fixed as it did have the dreaded logic board problem.
Any help would be greatly appreciated!
Thank you!
Brian

Hi again!
So this is with the new board? Was there sectoring of the lines?
If so that's the graphics chip most likely.
Yes. However, since this has gone on for a while and I never finished taking care of it, I can't remember all the details like sectoring of the lines.
The problem used to occur after the computer had booted and was on for maybe an hour.
So it freezes? That does sound like a GPU problem esp as it happens after an hour or so. (thermal flex causing separation of BGA)
Normally, yes. I have also gotten the kernel panic screen (You must restart your computer now). When it froze this morning, I had started to download a System Update. The clock ran, but I couldn't force-quit anything. What about the fact that the drive doesn't mount in Target Disk Mode?
You could pull the board and send it for reball.
I've also found a few boards on eBay that so far are less than the reball, but unless it was already reballed, then I run the risk of this happening again in the future, right?
Thanks again for your help!
Brian
