I have an older computer (Asus P5Q Pro Turbo) I use maybe once a week or less. One day it stopped holding BIOS settings. (I turn off power strip when not in use.) Had been booting up fine until one day I had to go into the BIOS to reset. I noticed the CMOS LED did not stay lit after I turned power strip off, so I got a new battery and tested it before install, to make sure it was good. It did not light the LED. The LED does work when powered on. I checked visible connections on the battery socket and everything looks good. Right battery, CR2032. Voltage 3.09 volts. The old battery was weak; just over 1 volt if I remember right. No new hardware/software. A minor inconvenience to reset BIOS every time, and I could always leave power strip on, computer works fine once BIOS reset. But just curious as to what's going on and if I'm missing something obvious.
