I have a 2011 macbook pro that will not boot. It tries to start up but then the fans stop and nothing happens. If I remove the RAM then the fans will keep spinning but it the computer beeps until I shut it off because there are no RAM sticks in. I have a feeling it is the logic board but really don't know if it would be worth it to replace it. Any ideas on how I could fix this?
Thanks,
Devin

Sadly if the system was working and it stopped your systems RAM slots have failed. A common cause is the mid frame clips have failed allowing the bottom cover to press down on the memory modules causing the trader of pressure to damage either the modules and/or the slots (marked in Purple). Also check the ground bar to make sure it's not damaged as well (marked in Green).
If they are damaged then you'll need a new logic board and getting new clips from a junker or making your own.
As far as why: A good bang on the bottom cover or something pressing on the bottom cover like a charger in a case and then something heavy sitting on the case could cause the clips to fail. We had so many failing we ended up 3D printing new ones.

did you try both slots seperately

Did it ever boot for you? Did something happen to it?

Can you give us some background info. Was it working with this RAM, or did you upgrade it? If you upgraded try going back to the other RAM modules.

I have tried both slots seperately and that does not work. The computer had the RAM upgraded and it worked for over a year. Then it randomly stopped working and was giving the beeping like the RAM was the problem. I never got a round to fixing it and now that I have it doesn't beep at all unless the RAM is completely removed. This make me think it has to do with how the ports that the RAM is seated in and that is connected to the logic board.

What is the beep pattern
