Clock not updating
Posted on 1998-09-28
I have recently been having a problem with the clock in the PC not updating properly while the computer is turned off. Assuming it was a battery problem I replaced it. One thing I noticed while doing this leads to the following questions:
I assumed that when I pulled the battery I loose the CMOS setting. However, I didn't. I later read that some PCs now store this info in non-volatile ram. OK, I'll buy that. However, the date remained correct as well even though the battery was out for several hours.
Is it the case that the date is also stored in non-volatile ram and it's only the actual clock that uses the battery power when the PC is turned off? Just curious.
