MacBook Pro does not turn on
This is a late 2008 / early 2009 15” MacBook Pro.
It was working fine when I shut it down to keep the battery from draining during a power outage. It was connected to the power adapter, which was plugged in to a surge protector. The shutdown happened normally, with no signs that anything was wrong. A couple hours later, when the power came back on, I tried to start it up, but it was completely inert. No lights, no sounds of the drive or the fan coming on. The only sign of life was that the light on the power connector was lit orange. Later it turned green, which tells me that the battery still charges.
It seems to me that it could be something as simple as a bad power switch, but I don’t have any experience with diagnosing this sort of thing. Since Apple won’t fix something that old, I’ll see what I can do on my own. I’m going to order some tools to take it apart and try spraying some keyboard duster around the power switch and see if that helps. If not, I guess I could try replacing the logic board at $250, but that seems a bit of a gamble without more to go on. Anyone have suggestions?
Ist dies eine gute Frage?
Have you tried an SMC reset? https://support.apple.com/en-us/HT201295

Thanks for the idea. Unfortunately, the only thing that happened when I tried it is that the LED on the charging cable plug briefly turned from orange to green, and then back to orange after a few seconds. I was still unable to power on afterward.
