anyone have AGC GPU crashes in the log of your KPs? I originally thought my issue was memory/dimm related, took it to the 'genius bar' they ran all the test for the repair extension program, and it came back clean, including the graphics/video test.

can someone point me int he right direction for the possible controller or chip piece that I can replace, or another solution .. cause I wont be replacing the logic board.. ask they suggest

@shaggy What hardware?

shaggy

@bmike its a late 2011 15" MPB

16gb originally, now running 8gb for trouble shooting purposes

4/4gb

@shaggy not much to repair in that other than the logic board - which doesn't get any sort of repair/diagnostic outside the original factory.

Did Apple deny / offer you a flat rate repair? That would be the way I'd repair it.

@bmike 700USD logic board, which is an option that i'm not interested in... at all

i was just wondering if there was any actual repairs that I could do myself, certain components to be replaced... soldered in. that could possible help my AGC GPU crashes

No - everything is machine soldered and you need sophisticated test harnesses to even isolate the issue and make sure it works again. If they didn't offer you the $300 flat rate repair, there must have been other damage that prevented an inexpensive repair - sending a damaged mac off for a flat rate repair often balloons untie $1250 to fix.

The only fix that makes any economical sense is to put a working logic board in to the place of the damaged one. Acquiring the skills, staff and tooling to rework Mac logic boards probably is in the $50k to $300k budget range.

Without a reflow oven and the correct profiles/cleaning/prep, you're lost on modern boards. The era of DIY fixable boards ended with these type of layouts:

@shaggy If they didn't explain why the $300 repair wasn't an option, maybe go back and ask again why the $700 quote.

@bmike well then, thank you for the well informed answer, its appreciated. and that was interesting to learn.. and well, haha, makes sense.. dam you technology!

the only other issue that was going on is my optical drive is dead, and they said they could send it in for 350, and then if the logic board is the issue that would be 700 on top, which doesn't seem like a practical option for me. maybe I'll take another trip in and see what another associate has to say, but if not seems I might just be SOL

really though, thanks for the info. may I ask what your background is? You seem to know their system through and through. If you feel uncomfortable disclosing such info, it's understandable. either way cheers!

~BTW, love that I'm getting points deducted from my post. thats appreciated

I've worked for Apple, I've repaired thousands of Macs, I've worked in software for 10 years before that and I have a totally useless/useful degree in theoretical physics.

I'm well acquainted with the retail teams and the end user's desires and ambitions to DIY repair - sometimes that is to be encouraged. Other times, discouragement is the best option. In yours - even putting a new logic board in is fraught with danger for someone that isn't backed by a company and certified. the changes of good outcomes are low on your first dozen attempts which is why training labs and other support for repair techs are worth the investment by companies.

@shaggy I would take them up on the $350 - it should cover everything and if the estimate goes up - have them call you and explain. You would then be able to cancel the repair instead of paying more than the initial estimate.

Back up all the data before you go in case you decide to leave it for the mail in repair.

shaggy

okay, that's awesome. thanks again for the insight. I'll take it back in and see what they can do for me. I just don't want to spend $350 on a replaced optical drive in the end.

its a clean disk image, so nothing to back up :D

No - ask them to test the logic board and the optical drive - make sure that's written on the work order. If for some reason, the board passes all the tests - you still have 90 days of warranty on the repaired computer - so it's important to document the kernel panics in the repair history. Have a list of the dates/times it crashed and you'll want to take it back if it keeps crashing for a repeat repair. My experience is if you have more than a crash a month - the board gets replaced.

2 crashes post repair should trigger a re-do if you ask them to repair it.

and paid for the $350
