tool, and when I deleted it, it did something that changed my BIOS. The black screen appears when I boot up and reads: 'System BIOS shadowed. Check time and date settings. System CMOS checksum bad--default configuration used.'" Robert says he's tried contacting both Phoenix Technologies (makers of the BIOS) and Emachines, and neither company could help. cmos checksum error dell (The BIOS dates back to 2003, and the system itself is long out of warranty.) Fortunately, this sounds like a pretty easy problem to fix. I don't think the driver-update utility is to blame here, but rather a poorly timed CMOS-battery failure. See, most desktop motherboards have a small battery that supplies power to the BIOS even when the machine is turned off. This battery might last two years or it might last 10, but when it fails, you'll often see an error message like the one above. (Your system will also fail to keep proper time, as the clock is one of the elements powered by that battery.) Most CMOS batteries are standard CR2032 "button" cells, which cost no more than a few bucks at your local drugstore, but check your motherboard documentation just to be safe.

I have a cmos checksum bad two year old Studio 8100 which has suddenly developed a CMOS Checksum Error on boot. Worked flawlessly until reboot yesterday. I have tried checking all connections, replacing the CR2032 battery, and the CMOS http://www.pcworld.com/article/240331/troubleshoot_a_bios_or_cmos_checksum_error.html reset jumper (shorting 1 & 2 for 5+ seconds...tried this twice). None produced any change in the problem. Screen prompt (with the error message) directs you to press F2 for Setup or F1 to Load Default Values. Unfortunately the system seems to be unresponsive to any keyboard commands at that point. Neither F1 or F2 do anything. Repeated pressings of other random keys will eventually fill the http://en.community.dell.com/support-forums/desktop/f/3514/t/19464519 buffer and produce the expected beep in protest. I'm kind of at a loss. Never had an error like this which I couldn't figure out or clear. Any suggestions at all would be greatly welcomed at this point! Thanks for your assistance.

Try this: Power off and unplug Press/hold power button for ~15 sec Disconnect all peripherals Remove motherboard battery Press/hold power button for ~30 sec Leave it unplugged, without battery for several hours or overnight. Reinstall the battery (right-side-up!) See if it bootsnowwith only mouse, monitor and keyboard connected.
