Power Button Not Responding as Normal
So I fix computers a lot, but this one has baffled me.
My friend gave me her MacBook Pro that she bought second hand, because the power button doesn’t turn the computer on. First I though the battery could be dead, or the board could have died.
After further diagnostics, I found that if you unplug the battery, plug it back in, press the power button, and then, once you connect the power adapter, it boots up.
So the computer ‘technically’ works completely fine as it should.
My question is, what could be causing this? And are there any hardware fixes I can do to solve this?
Note: I have replaced the thermal paste on the machine, updated the software and replaced the battery already and neither of these solved the issue.
Thanks in advance guys!
Is this a good question?
