Cmos Checksum Error Defaults Loaded
batteryreplacement Bysomnamblst Mar 9, 2003 I am readying an old PC I built (686 Cyrix 200 Mhz) to give to a brother who has never had or tried a computer but is expressing some curiosity. Long story short I discovered several issues when I powered up this PC to ready it for a car ride to Florida that is leaving soon. cmos checksum error press f1 to continue 1. CMOS battery/Checksum error, removed old 2032 battery 2. I also removed a non functioning primary slave Seagate HD 3. Installed new battery 4. On reboot HD was not detected, auto and user defined HD did not work, system kept reverting to 9/1/1996 date. CMOS/Checksum errors continue despite new battery. Also moved jumper on HD to reflect single drive status. 5. Swapped power supply from CD to primary master HD (Western Digital) resulting in HD being detected. Used a different power supply cable for CD resulting in CD but no HD. Removed jumper from HD completely and tried a 3rd source for power to CD which worked, HD and CD detected, continued CMOS/Checksum errors mean Plug and Play enabling in CMOS is not being retained and must be enabled through setup to continue booting. AND with the cover off and the tight fit of swapping things in a desktop I also noticed that the CPU fan is not spinning. I am not sure when this happened, I was feeling heat on my hand all along as I manipulated cables. Good thing

During boot, I get the following error message: CMOS checksum error - Defaults loaded Indeed, the time, date, and boot device priority are reset and the values I had set up before switching the computer off are gone. My first explanation was that the CMOS battery must be empty so I bought and installed a new one. But the behaviour has not changed: after switching off and disconnecting the power cable, the next time I switch on, the CMOS settings are lost and the error message is printed again. Any suggestions as to what I should check next? EDIT Following the suggestions contained in the answers and comments, I performed a few further tests using another computer that I know is working properly, i.e. it does not lose BIOS settings between reboots.
