    The way to solve a checksum error is to leave it alone. It only happens on startup to let you know something has been changed. If the battery dies and bios resets, if you flash or make changes in the bios, sometimes the changing or even data comparison of some type would cause it. It is only a warning to let you know something has been changed and will only do on startup while doing its routine checks one time. It means, "something is different about this startup than the last one".

If you are using an old computer, there’s a possibility that you already encountered this error message during bootup; “CMOS checksum error – Defaults loaded”. At this point, the PC will halt its operation and requires you to press F1 to continue or DEL to enter setup (mostly but also depends on motherboard) to proceed.

This is caused by incorrect or corrupted CMOS values. BIOS settings are stored in CMOS. Each time the system is booted this number is recomputed and checked against the stored value. If they do not match, the error message will be displayed.

For most cases, this is caused by the motherboard battery. Buy a new one to any electronic retailers in your area and replace it. Turn on your computer and press the stated key to enter the BIOS setup. It can be DEL for some or F2 but this depends on your computer. On the BIOS menu, try to change the DATE and TIME settings because their values are reset to different value. Most settings are set to default so leave it as it is. Save the settings and reboot your computer.

The CMOS Checksum Bad Error during the pre-booting process only indicates that the CMOS battery is exhausted and it can not no longer save the current BIOS settings, Time settings and many more things.

The first and and the only way, according to me, to solve this problem is to replace the CMOS battery.

Please let us know, if this solution have helped you.

Hope this helps, Mrityunjay.

Hi.

The most probable reason you are getting the bad checksum error is you have to set the date and time because you have cleared the CMOS and reset the BIOS.
You should also get a message that says press F1 to load defaults or press a certain key to access setup. Access setup (BIOS) and set the date and time. That should take care of the bad checksum error.
Another good idea is make sure the motherboard battery is not dead either.



Regards.

Always start up with cmos checksum error, cpu ratio has been change


A BIOS checksum error is most likely caused by a flat BIOS battery.
Replace the battery with a new one (it is usually a coin size battery - type CR2032) and then boot up and go to the BIOS configuration and set the Date & Time setting etc.

Bios ROM checksum error (Compaq SR5237CL with M2N68-LA MB)


A BIOS checksum error can be caused by a nearly flat BIOS battery.
I would replace the BIOS battery first before attempting to upgrading the BIOS.
Some motherboard BIOS firmware is upgraded by running a program that has been copy to a DOS boot disk or the upgrage maybe done from within the BIOS setup. These firmware upgrage and instructions are on the motherboard WEB site, in your case the Compaq/HP WEB site. Make sure you select the upgrade for your model motherboard.
NOTE it is possible that if you make a mistake you could ruin your motherboard, if you are not sure seek help from a computer savy friend.
