Long story short I discovered several issues when I powered up cmos checksum error this PC to ready it for a car ride to Florida that is leaving soon. 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 als

I'm getting a checksum error when I boot. I replaced the battery on the motherboard after first unplugging the computer. I then rebooted and corrected the date and time, loaded and saved the factory CMOS defaults, and the computer starts fine. However, if I turn it off and switch off the power strip, the CMOS memory is lost and I must repeat the process. I've checked the battery. Any ideas? Thanks.

You could also check with Gateway to see if there is a BIOS update to address this problem. Unless the computer has been subjected to a power surge I can't understand why this should be occurring. Below is a link to Gateway downloads. It appears there may be some BIOS updates. The latest one gives no reason for the update. Be aware that flashing the BIOS MAY result in a non operational computer.http://support.gateway.com/us/en/pr... See in Thread ↓#1 phil22 September 28, 2012 at 08:44:46 Did you check that the new CMOS battery is the same way up as the old one was? (usually the '+' side of the battery should be face up).If it's inserted the wrong way up it won't do any harm, but neither will it be able to do it's job. Report • #2 timothytech September 28, 2012 at 10:45:08 Oh, yes. It's in correctly. (I'm a retired sound and communications service tech. I'd better know by now which side of a battery is which!) I know maybe the next step is to m
