Will not boot / Pulled top cover and got it to boot
The MacBook would not boot. I could hear the disc drive make noise and the fan come on but no video or booting. I pulled the top case and put it back on and then all the sudden it booted when I push P R option command keys after booting. I had the top case sitting on top and and it booted and was at the desktop in the OS when all the sudden it went black. Seems like a loose cable. Now it is back to where I started and I can't get it to boot again.
Is there a way to boot without the top case? I can't find any jumper on the logic board on this model.
Is this a good question?
