We got a nice little shower here for the first time in several weeks, and the electricity went out for almost three hours. Typical of the pinheads running the local power company! Had to unplug the PC and my cordless phone during that time, for the first hour or so, the electricity was popping on for about a millisecond every ten seconds or so, just enough to make the fan blades turn about an inch each time. Didn't want any "power surges" blowing anything out, even though it's all plugged into a surge protector. Normally don't unplug the cordless phone, but each time the power surged, the phone made a series of "beeping sounds", and after hearing that about every ten seconds for a half hour, I couldn't take it anymore and HAD to unplug the thing!
