MacBook Pro don't turn on

I have a MacBook Pro 2008-2009 and the following are problems with her, i turn off in the night and at the morning he did not turn on, the light from sleep mode don´t turn on, he not give sign of life ... after a while after Early attempts to turn it on it turns on, and that makes both with and without battery, but the times the battery out and put some times it turns on, otherwise just plugged and unplugged the battery he turn on.

Since I spent some time using it without the battery, i thought that problem is because this so, I bought another battery and the problem continues with another already tested Magsafe, and nothing, I reset the SMC and still nothing, the problem occurs only of a day for other, if I turn it on and off several times during the day and he does not present this problem more ...

If someone can give a solution ...

MacBook Pro, Mac OS X (10.7.2)

Hi,

Sounds like a faulty power button, or a logic board on its last leg: using your MBP without the battery will undervolt the logic board. If you've used it like this for a long time, then put the battery back in, it's possible that a power surge occurred, and that your logic board suffered from it. Just a maybe, though... I'd look at the power button first.
