Hi,

It was working fine before I disassembled it.

I took the CPU out of its socket. Is it possible a bent pin or something could be causing this?

I've stripped it down to minimum: power supply and logic board only with no key switch. I plugged in a keyboard so i could use that as a "power switch", and got the same results.

I will check the CPU and see if that's the culprit.
