I have a MacBook Pro 15″ Late 2008 (5,1). Sometimes it just won't power on. It works fine. I shutdown, then when I go to turn no it just does nothing. Previously I removed the battery and the charger, pressed the power button for a few seconds (so as capacitors can decharge etc) and then it powered on. The last 2 times, I couldn't turn it on for two days. After two days I just pressed the power button and it turned on.
Note that no water has been spilled or anything like that. Are there any recommendations? Any known issues with workarround?
