Almost impossible to cold boot my MacBook Pro that I bought used.
Hey guys,
So I have this problem where it is almost impossible to cold boot my MacBook Pro.
Resetting the SMC does not work. So here is how I got it working. I unscrewed the bottom case, disconnected the battery, and then connected the AC adapter. Then I was able to do an SMC reset and power the system.
It works great without the battery! So I closed the lid and let it go to sleep. I waited a bit until the fans stopped. Then I plugged the internal battery back in and open the lid and it works fine.
Battery is listed as "normal" condition. Everything seems to work. When I do a restart, I tried holding down D to go into the diagnostics and it runs the diagnostic and finds no errors.
I can live with just not doing a full shutdown. But, eventually I might want to fix this issue, any ideas on how to fix this? I really hope it is not a logic board problem.
Is this a good question?
