I've got a mid 2010 MPB with 8 GB of memory. It runs well and has never had any serious problems that I couldn't resolve. I generally use it like a desktop with a magic mouse and a external monitor. The other night i was playing a game when the system shut down.
The screen went black; I got the no signal notice, and I noticed the computer had shut itself off. I rebooted--it took longer than usual--and notice that the power adaptor was orange indicating it was charging the battery. I clicked on the battery icon on the menu bar to display the percentage of charge and it showed 4 percent. I've got a UPS and it had not engaged. I shut down the system and went to bed.
The next morning when I booted up the system ran fine and the battery icon showed a full charge. No problems since. Does anyone have an idea as to what caused the shut down and why the battery was so low? Does this portend a looming problem such as a battery going out. I'm pretty good about exercising the battery--taking it down to near zero and recharging on a fairly regular basis. Any ideas?
