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 cmos checksum bad usb device over current status detected Error is an error that occurs when the CMOS values turn out to be incorrect.
Cmos Checksum Bad After Bios Update
The CMOS memory stores a specific value normally to guard the BIOS software. Each time the computer is booted, this value, which is a cmos checksum bad press f1 to run setup number is checked against 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 http://www.tomshardware.com/forum/278461-30-cmos-checksum-error the CMOS Checksum Bad Error 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 http://www.tech-faq.com/cmos-checksum-bad-error.html Error occurs. They include: CMOS Battery may not 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 update

The black screen appears when I boot up and reads: 'System BIOS shadowed. cmos checksum 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 cmos checksum bad 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?

Travel Health Medical Cars Technology Home Family Business Interest Woman Editorials » Technology » Technology What is a Cmos Checksum Error and How Do You Fix it By: Robert - Bad or old CMOS battery: Reboot the computer. If the error still occurs after rebooting, enter CMOS setup and check all values, this includes verifying that the time and date are correct. Once everything has been verified, make sure you save and exit the CMOS setup. If everything appears to be proper and the issue persists, try resetting the CMOS values to the defaults and/or Reset Configuration DataNote: If this issue continues to occur after you turn off your computer off it is possible that the CMOS battery may be weak or already used up. More details about replacing CMOS values can be found on your motherboard's manual- BIOS update:If you had recently updated your BIOS of the computer, the CMOS values could have been reset. Enter the CMOS setup and re-enter all the appropriate values. More details about entering the BIOS setup can be found on your motherboard's manual.If you are unable to enter into the BIOS setup or after running a BIOS update, your computer no longer keeps its values, it is possible that an incorrect BIOS update may have been installed for your computer or the version may be corrupted. We suggest you try to update the BIOS again or roll back to an earlier version. - Disconnecting power supply before properly shutting down the computer:If the power had been disconnected to the computer while running, it is possible that this could have corrupted the CMOS. Therefore, ensure that the computer is properly shut down before switching off the power supply. If you have a laptop, ensure that the battery is at least 25% charged before switching off the power supply. If the CMOS has become corrupted, enter the correct values in CMOS setup and save and exit the CMOS. This would surely solve your problem.
