MBP Late 2011 turns on full fan but no display

[benyben123]

Hi everyone.

Out of blue, this morning I turned it on, no display at all. Full fan speed after a few seconds (gradually increases till full speed).

I did a PRAM and SMC reset.

After the SMC reset the display did turned on (grey) with Apple logo and displayed a kernel panic message (cpu something). I did not catch that on camera.

At least I know it's not the display itself.

BTW - I tried to hit the caps lock button but it won't turn on. Maybe that's a sign.

Also, another reset resulted in stuck on Apple logo boot up screen. But no chime.

I guess it won't post.

Opened it up. Looks rather clean.

Any suggestions whatsoever?

(I upgraded this device to a 500GB SSD and 32GB of RAM a few months back).

Sounds like the GPU died. The symptoms you described are typical for when the graphics fail. Fairly common in your model MBP. You can do a search of the forums to learn how others have dealt with getting it repaired and what it entails.

32GB ram? I thought unofficially 16GB ram.

Exactly how mine behaved when the GPU died (very common as mentioned above, just look up "radeongate"). You have got a few options to keep using it. I reflowed the solder on mine a few times (its more a temporary fix), before disabling the dGPU entirely by removing a resistor and doing a few nvram edits (a permanent "fix"). It sounds to me as though yours might be too far gone for simple software tricks to do anything.

Really appreciate the answers guys!
Thx so much @alvindarkness @chscag

And @WhoNet - perhaps I am mistaken and it's 16GB. Will actually check soon and let you know. Now I am curious as well
