i7 MBP 8.2 AMD 6750M 2011 Crashes, Red Horizontal Lines, won't boots

OH NO! This morning, the same laptop, with the Depot Repair replaced logic board, had a dead battery. It only boots to grey or black screen!!! 😟 The SSD drive boots a Mac Mini just fine! Looks like a second bad logic board! 😟

My colleagues (two) and myself are having this problem. Based on our troubleshooting, discussion and observation. We suspect that all 3 of us having a bad Logic Board/GPU (MBP 8.2). There are a significant occasions when the fan will run very fast (>6k rpm) for no clear reasons (was just running a few tabs of web browser). And one day, the MBP will just crash and refuse to boot, even with other hdd or USB restore disk. Red horizontal lines on apple boot screen and then turned to blue screen while fan is spinning very fast, at this point the MBP will get very hot.

This model (MBP 8.2, Early 2011) is no longer under Apple warranty. We appreciate any updates on this particular model. I am very interested to know what happened to you unit @Karl Ihrig. It seems like you have a second bad logic board?

Thanks.

muzaaliff,

I had problems very, very similar to your own. My GPU blipped out first but I could run the Apple Hardware Test and no problems were found (except for the horizontal lines on the screen). But I could not boot from any device and when I tried Internet Recovery I had black and blue vertical lines.

I ended up having my logic board replaced (gratis as I have AppleCare until 2015). That's been 4 days ago. So far everything's fine but I've no idea if this will 'last.'

Good luck with your machine,

Clinton

@clintonfrombirmingham,

Thanks for your prompt respond. It's a good thing that you have AppleCare extended warranty. All 3 of us didn't opt for AppleCare at the time of purchase. Since it's 3 of us having same problem and I believe many more out there; I am just wondering if it's a design/manufacturing flaw for this specific model and if there's any recall program by Apple to fix this. I'm Not sure how much a logic board costs in UK ( I assume you are from Birmingham? 😉). But it is quite expensive here. Anyway, I don't imagine it'll be cheap anywhere.

I wish you all the best for your new LB/GPU. Hopefully it'll last another few years of good service.

Thanks.

Birmingham, ALABAMA, US. But I'm not a native - just landed here by a series of accidents.

My quote for the logic board and labor (before the Genius realized that I had AppleCare) was just under $500USD. Costs are probably less expensive in the US than in any other country, though.

I believe, now, that the problem is with the lead-free solder used on the GPU. Folks that have had the old GPU BGA reballed seem to have solved their problem. And some, of course, have gone so far to have a new GPU 'expertly' installed (which seems a perfect solution).

I do hope this machine lasts me awhile - I'm not really enamored of the closed Retina models...

Another thread for reference.

problems with amd gpu on early 2011 macbook pro

Just had this problem with my MBP 17inch.

Typical as the extended warranty has just ended. Wish I had seen this tread before as I did have problems going back a couple of months, which was in the warranty period. :-(

bassoonman2,

Take it to Apple. They aren't telling people how to fix it themselves. Have the genius look at it. They should offer you depot repair warranted repair for 90 days for $310. Just keep bringing it back to Apple until it gets fixed. Mine took three times, and they refunded the repair price, without me asking, saying I could continue with cycling 90 day warrantees. So they fixed it for free but wasted a lot of time and logic boards. I bought computers to keep me working through this process. The last time I bought another power supply just in case the old one was the problem in an effort to break the repair cycle. Mine has been working for almost a year since then.

Hi All,

I just been through this f**king s**t , details description of issue is as follow:

• red horizontal lines display right after you startup,
• it will go on to show you the apple (still in red horizontal lines),
• then it show the gray screen,
• and your fans start running like crazy.
• If you switch to window OS

  you will be able to run on safe-mode, and the screen look like... well you know

My conclusion is the RAM. not normal issue, a special RAM issue. I followed these steps and fixed it.

• Take out one RAM
• reboot on recovery mode, (press and hold: command + R)
• then it will display a crappy screen again still the apple sign
• then it will turn blue.
• Dont panic, shut it down
• this time do the RAM boot (press and hole command + option + P + R)
• if the RAM you are using is ok, everything should back to normal.
• if not, then replace it with the one you just took out and do the whole thing again.

i try command + R singly, and it not work. I tried reboot RAM (press and hole command + option + P + R) alone, it not work. only when i combine them, then it working. Also, it you put the faulty RAM in and take it out, even though you are on the "ok" RAM, the problem still exist without doing the process that i just described

Hope this help, and stop paying apple for non-sense things. 😎

P/s: I keep wondering why all macbooks suddenly have the same issue at the similar period. If Apple do this on purpose to make us purchase new stuffs ?

changing the logic board doesn't solve the problem! I have the same problem with my MacBook Pro 2011 and now it is at my "Service Provider" for the 3. time. They will replace the logic board for the third time now but i have no hope that it will help for long because the same bad gpu is on it and that is really all s..t! I do it because i am still on extended warranty but wouldnt spend any money on this! I am now - after 25 years with Apple - looking for alternatives...
