The battery supplies the charge that holds the information in CMOS memory when it looses the information after shutting down the battery is too weak to maintain the information. Make sure you get the exact number replacement battery its usually a 2032 3V Lithium, you can use any brand Duracell, EverReady, Etc., just make sure the type is the same and when reinserted the writing is visable. 4Ryan6 a c 351 K Overclocking a b V Motherboard December 30, 2006 11:21:00 PM After you change the battery you'll have to reset the date and time once more but that should be the last time you'll have

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. http://www.pcworld.com/article/240331/troubleshoot_a_bios_or_cmos_checksum_error.html 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. Replacing one is usually a two-minute job: pop out the old one, pop in the new one, and you're done. After that, you'll probably need to venture into the BIOS to reset the clock and double-check other system settings (like boot priority). Just be glad this didn't happen to your laptop. Laptops use CMOS batteries just like desktops, but on most models they're difficult--if not impossible--to replace. Which begs the question: After all these years, why haven't laptop manufacturers figured out a better way to power the CMOS? Contributing Editor R

I regularly have the folllowing line appear when my bios starts up - CMOS checksum error - defaults loaded. It seemed to start happening when i downloaded spybot search&destroy. I have since removed the program checksum error but still have the problem. I have changed the cmos battery on the mobo as recommended in other threads, but it still regularly (every few start ups) happens. Any advice to solve the problem? The board is only six months old. CPU and RAM test fine. I have two hard drives, non raid, sata connection. Nov 25, 2005 #1 netbus TS Rookie when i started reading ya post.. i thought at the cmos battery too. the message from cmos happens because cmos checksum error the cmos has been reseted. this ussualy is done or by removing the battery temporarily... or by a jumper on the board. you replaced the battery so this isn`t a problem anymore. maybe the battery isn't fit correctly. or the jumper is not correctly set.. and periodically the contacts are touched. you should check both . it this fails.. is a motherboard problem... the cmos information is lost due to power lost from the battery that powers it. Nov 25, 2005 #2 nig TS Rookie Topic Starter Thanks for that I will look at the jumper and let you know..... Nov 26, 2005 #3 nig TS Rookie Topic Starter Ok checked CLR_CMOS (Clear CMOS) header and it looks fine - nothing touching the two wires, its open. Its a GA-K8NXP-Sli board and there is no jumper as standard. I checked the battery and changed it again. The problem persists - the CMOS checksum error came up again and the defalts were loaded. Nov 28, 2005 #4 iss TechSpot Chancellor Posts: 1,994 it is possible there is some sort of corruption in the bios. have you checked for bios upgrades for your board?
