CMOS battery. If the user cannot locate the pin battery, the help of a computer technician should be taken to prevent damage to the hardware or motherboard. The CMOS checksum error - defaults loaded should be solved after changing the CMOS battery. Symptoms Solutions: Symptoms When starting your PC, the following error message is displayed: CMOS wrong CMOS MEMORY size WRONG CMOS Checksum Bad CMOS checksum error defaults loaded Warning! CPU has been changed cmos checksum error press f1 to continue please re-enter cpu settings in the cmos setup and remember to save before quit!

Report • #6 OtheHill March 2, 2012 at 07:26:51 Is this a custom system or store bought, like Dell, gateway, etc.? If custom your need to start tapping the Del. key continuously as soon as you turn on the computer. If store bought you need to read the screens to see which keystroke gets you into the BIOS (setup) screens and tap just like I described.Do not connect a PS/2 keyboard while the system is under power. Don't use adapters on it either. Report • #7 steve123123 March 2, 2012 at 08:09:59 could u tell me y some kkkkkrrrrrrrrrr

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. (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
