Oh, I am a happy little geek. My laptop is plugged via USB into the APC UPS, which means very little to someone who can't decipher the alphabet soup, but -- basically, the laptop recognizes the UPS as a back-up battery instead of wall current, so should the power go down, the UPS will tell the laptop that it's running on a battery now -- granted, a big-ass battery, but still a battery -- and the computer will happily go over into power-saving mode and hibernate itself if there's need. Whee!
