About 20 minutes ago I was surfing the net, and my computer blinked off. Strange. I knew the battery was close to toast, so I brought it downstairs to plug in. I pressed power, logged in, and OS X booted up. However, I got a strange error message saying that my "computer's internal clock was set to a date before March 24, 2001... some applications may act erratically". Nothing would open, and everything usually in the upper right hand corner was missing - time, battery, etc... and I couldn't get on the internet at all. So I rebooted again, opened up system preferences and my computer was set to 12-31-1969. I set the current date, and now everything seems to be fine. What the HECK happened?
