Pressing power button won't do anything
I have a late 2008 15" mbp that's been working perfectly. Earlier this year it started to have problems booting up, when I start it from shut down the power button doesn't seem to do anything. It only worked when I remove the battery and ac adapter and hold the power button for more than 10 seconds then connecting it back to one of the power sources, either ac adapter or battery, and pressing the power button again. That worked for almost a year now without any problem however today it won't start no matter what I do. There's no response whatsoever, no sleep light, no startup chime, no fan spin, nothing at all. The ac adapter lights green when connected and the battery indicator shows full charge when connected. I can't think of anything that is faulty except the power button itself, could that be possible or could it be something else?
Is this a good question?
