CMOS checksum error. Â However, while this error might be extremely frustrating, there are fortunately only a couple of problems that can cause

this error, all of which are easily solved.
What does this error mean?A cmos checksum error press f1 to continue checksum is a value stored in the CMOS memory in order to guard your computer's BIOS software. Every time cmos checksum error dell you boot up your computer, the current value is checked against the stored value to detect whether or not the BIOS was changed. If these two values are the same, the computerLoi Cmos Checksum Error
boots normally. However, when these two values differ, the system flags it as a CMOS Checksum error.
What can cause this error?There are usually 3 main reasons for the System CMOS checksum bad error:How can I fix this error?If a user or virus updated the BIOS:At boot, go into the BIOS screen by pressing del or F2 or the specific key combination designated byCmos Checksum Error Defaults Loaded Solution
the motherboard (it should be displayed on the boot screen). Reset the BIOS settings back to default while checking that the date and time are correct. Afterwards, make sure to run a virus scan to ensure that a virus didn't cause the error and the BIOS settings are still correct.
If the CMOS battery expired or isn't functioning:If you suspect this is the error, the battery can be easily changed. Before actually making any hardware changes, reboot the computer to ensure that the error still exists. Make sure to write down all the CMOS settings (if you lose them, you can obtain them from your computer manufacturer). Using the motherboard's tech manual, locate the battery and remove it. Afterwards, replace it with a new battery with the same specifications (voltage and size) and reenter the CMOS settings.If the computer was not shut down properly:Make sure the computer shuts down completely before turning off the main power by going to the Start Menu and clicking Shut Down.At any point, if you ever feel uncomfortable working with your computer or would rather have a trained IT professional do the repaiThe PC Guide Tip Jar.

Explanation: A checksum is computed as an error-detecting code, to protect the BIOS settings stored in the CMOS memory. Each time the system is booted this http://www.talklocal.com/blog/2013/01/s/computer-repair/system-cmos-checksum-error/ number is recomputed and checked against the stored value. If they do not match, an error message is generated to tell you that the CMOS memory contents may have been corrupted and therefore some settings may be wrong. BIOSes react in different ways to encountering this sort of error. Some will warn the user and then continue http://www.pcguide.com/ts/x/sys/booterrGBER08-c.html on with whatever settings were in the CMOS. Others will assume that the settings that were in the CMOS were corrupted and will load default values stored in the BIOS chip "for safety reasons". The error message will indicate which your system is doing. Diagnosis: The most common cause of checksum errors in CMOS is a battery that is losing power. Viruses can also affect CMOS settings, and motherboard problems can also affect the stored values. Recommendation: Follow the instructions in this section to address the CMOS corruption. You should make sure that all of the BIOS settings in the system are correct, by rebooting the system, going into BIOS setup and double-checking all the values (hopefully against a recent BIOS settings backup).

The CMOS contains data related to BIOS and may have been reinitialized. It may also be possible to fix the problem by reinitialising BIOS. The problem could also occur due to the depletion of the 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 please re-enter cpu settings in the cmos setup and remember to save before quit! You are prompted to: Press F1 to resume Press F2 to load default values and continue This is due to the fact that the CMOS, which contains data related to the BIOS, has been reinitialized and that your PC has been reset to factory settings. Solutions: Reinitializing the BIOS Before making any costly maintenance try: reinitialized the BIOS. Change BIOS battery If the problem persists this may be due to the fact that the battery powering the CMOS (when the computer is shut down it allows the CMOS to store information), is depleted. The CMOS battery is a small pin found on the motherboard; you can refer to the manual provided with your motherboard to change it or have the nearby computer technician change it for you if you don't want to risk any damage.
