Cmos Checksum Error Fix
fixes for your PC hassles Home PCs Troubleshoot a BIOS or CMOS 'Checksum' cmos reset 502 fix Error Comments By Rick Broida, PCWorld Sep 21, 2011 9:40 AM Reader Robert has an older Emachines desktop that recently developed 0251 system cmos checksum bad default configuration used a problem: "I installed a driver updater 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 http://support.hp.com/us-en/document/c01368145 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. http://www.pcworld.com/article/240331/troubleshoot_a_bios_or_cmos_checksum_error.html 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?

the CMOS Checksum Bad Error, hence they can be handled effectively. The Error Explained A checksum is computed as an error detecting code to guard the BIOS settings stored in the CMOS memory. The CMOS Checksum Bad Error is an http://www.tech-faq.com/cmos-checksum-bad-error.html error that occurs when the CMOS values turn out to be incorrect. The CMOS memory stores a specific value normally to guard the BIOS software. Each time the computer is booted, this value, which is a number is checked against https://answers.launchpad.net/hplip/+question/171380 the stored value in the CMOS memory. If these two values are different, it causes a CMOS Checksum error message. If these values are the same, the computer boots normally. Each computer usually deals with the CMOS Checksum Bad Error cmos checksum differently. Some computers warn the user and continue to boot up using settings in the CMOS, while other computers might warn the user and use the default settings in the BIOS as the correct settings and carry on with a normal boot or reboot. Usually, the strategy the computer employs is stated in the error message. Causes of CMOS Checksum Bad Error There are usually three main reasons that a CMOS Checksum Bad Error occurs. They include: CMOS Battery may not cmos reset 502 be functioning properly. The battery life may have expired. The user or a virus may have updated the BIOS. The computer may not have been shut down properly e.g. shutting off the computer's main power without first shutting down the computer (MS Windows requires the computer to be shut down before the power is shut off). Solutions to CMOS Checksum Bad Error The CMOS Checksum Bad Error can be fixed easily by following the listed steps carefully. CMOS Battery May Not be Functioning Properly If the user suspects that the CMOS battery is not functioning properly, he/she can easily change it. Before changing the battery, reboot the computer to make sure that the error still exists. If it does, go into the CMOS and write down all of the settings. If all the settings are lost, they can usually be retrieved from the computer manufacturer. Now locate the battery and remove it. Consult the computer manual or technical support to remove your battery (the battery is flat, shiny silver colored, and coin-shaped) if needed. Take down the CMOS battery’s information such as volt, size, etc. Replace the old battery with a new one and reenter the CMOS settings. If the battery caused the CMOS Checksum Bad Error, the problem should be solved. The BIOS May Have Been Updated If the BIOS was recently updated, the CMOS settings may have reset. Make sure that the values entered in the BIOS are c
