And what if you have changed the battery, done your bios settings, done save and exit, even installed a new cmos chip but the problem still reoccurs each time mains supply has been switched off. Sorry mate , not always so cut and dry. I have done all of the above and still have the problem. Can even leave the cmos jumper rest off, which is supposed to stop the system booting, yet the system still boots fine. This to me points to a breakdown in the board circuitry. ****, i can even leave the battery out of the board and as long as i don't switch off mains power all settings save and the system boots with the bios settings i have made still intact. I agree with you mate, nine times out of ten it will be the battery but not always. So if you can point me to the problem with my board i would appreciate it.
