From time-to-time, my Mac Book Pro won't wake up after it goes to sleep. I gently tap its track pad--nothing. I softly bang the space bar--no response. I try pressing the power switch, but the screen remains black.
At this point, I'm in a conundrum. How am I to wake up the sleeping machine if pressing the power button doesn't elicit a response? I actually had this same issue with my old Sony Vaio laptop and I always assumed it was (ahem) a Windows problem. I guess not.
Here's what you need to do:
- Detach the power cord.
- Turn the MBP upside down and remove the battery.
- Reinstall the battery
- Reattach the power cord.
- Press the power button and you should be fine.
For some reason, every once in a while the machine just gets lost and this brings it back from its quiet slumber.
