Why doesn't my computer keep time when its turned off?
Please view my Notices page before viewing this area, it is not complete!
This is work in progress.
It's quite likely that the back up battery on the motherboard is dead, you
should replace it, but if possible check out the battery with a volt meter

Trawled this site and still can't find the solution to your problem?
If so I highly recommend The DOS Board.
It has several good techies waiting to answer your questions and I
hang around there a lot too.
