I let my MBP run last night and I fell asleep and it died, obviously. But this morning when I tried to turn it on by plugging it in, it wouldn't turn on. So I took out the battery and then plugged it in without the battery and it still would not turn on. I left it without power for a few minutes to discharge and tried again both with the battery and without (using the plug) and didn't get anywhere. This has happened before and eventually turned on again, anyone know what is the problem? Oh, when plugged in the adapter is lit up green, not amber. Suggestions are appreciated!
