This is a potential solution to a common problem with no video on your MacBook Pro.
If you’re faced with a black screen of death, then this may solve your problem quickly.
Only try this if your situation matches the following conditions exactly.
If your situation matches all of these criteria:
1. You own an older MacBook Pro Retina (various years, though in this case it was a 2012 I had a problem with)
2. You are getting no video – either on an external monitor or built-in display but…
3. Everything else works. You get the startup chime. You can even log in and perform actions using memorized keystrokes.
4. You’ve tried all the standard, non-invasive tricks like resetting PRAM, reset NVRAM, reset SMC, as well as other tricks like overheating the computer in a thick blanket.
5. You’re now considering using a heat gun, or baking the logic board in the oven.
Repeat: If you’re not getting the startup chime, this probably doesn’t apply to you, and this probably will not work.
Also, I have to underline that this is just my own experience. I’m not a Mac expert. I just tried this blindly, and it work. At the time of writing, I don’t know anybody else who’s tried this, let alone succeeded.
1. Turn off your MacBook Pro and unplug it.
2. Turn over the Mac Book Pro and remove bottom case using a specialized pentalobe screwdriver. Yes, this part sucks, because of the small cost for these tools, and the time it takes to get them.
See this post from ifixit.com for the best advice on where to buy this screwdriver, or head over to your local independent computer shop.
3. Examine your logic board. See this dude?
3. Using just your thumbs, press quite hard on opposite corners of this chip. Press on one pair of opposite corners (as shown below), then release and press on the opposite pair.
I only pressed for two or three seconds. It’s not about the time spend, it’s about the force.
4. Flip the machine over and turn it on.
It sounds barbaric. And it sounds too easy, and too good to be true.
But it actually worked for me. Much to my shock.
Is this GPU Fix Permanent? Is it Better than a GPU Reflow?
As I say in the attached video, this fix is probably not permanent. I first did this procedure 14 days ago (at the time of writing). Since then I’ve had to redo it twice. So this will not be a permanent fix, but it will definitely buy you time, while you figure out your next purchase.
I can’t say whether it’s more effective than a GPU reflow, but I do know it’s a heck of a lot faster, and won’t require you to find a heat gun.
I strongly suggest that you save any work you do on this computer to Google Drive, Dropbox, OneDrive, or some sort of portable media. Or use TimeMachine. It’ll make your transition to your next Mac product a breeze.
