Checksum error at boot up , the message "Checksum error : press F1 to continue or ..." appears. My PC is 5 years old. Could be due to the CMOS Battery that has low voltage? How is it replaced ?

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.

Hello, when I put my pc running it says CMOS checksum error press F1 to enter or Del to enter setup, but I press Del when I save changes "save and exit" the computer restarts, but this time...


The Checksum error basically shows that boot settings which were previously set has been changed or reset. This usually happens when the battery loses its charge and thus fail to retain the CMOS settings. This can also be caused by a power surge or a damaged motherboard. But most of the times it would be the battery problem.

You can try replacing the CMOS battery and enter the values back into CMOS or reset values to default. Then switch off and boot up again.
Hope this works. Good Luck. ~SmokinJoe~

Ref GA-81PE1000L Error message on boot up


all the computer bios settings are stored even when the computer is off (like time and fsb)

these are stored due to the help of a cmos battery

when this battery finishes it gives the CMOS Checksum error Default loaded error

all you need to do is replace the cmos cell

it is a mercury cell (looks like a silver coin) and will be placed on your motherboard

it is very very cheap so go buy one and replace it and be happy

Boots to 'CMOSS checksum error'


CMOS checksum errors
Explanation: A checksum is computed as an error-detecting code, to protect the BIOSsettings stored in the CMOS memory.Each time the system is booted this number is recomputed and checked against the storedvalue. If they do not match, an error message is generated to tell you that the CMOSmemory contents may have been corrupted and therefore some settings may be wrong. BIOSesreact in different ways to encountering this sort of error. Some will warn the user andthen continue on with whatever settings were in the CMOS. Others will assume that thesettings that were in the CMOS were corrupted and will load default values stored in theBIOS chip "for safety reasons". The error message will indicate which yoursystem is doing.
Diagnosis: The most common cause of checksum errors in CMOS is a battery that islosing power. Viruses can also affect CMOS settings, and motherboard problems can alsoaffect the stored values.
You should make sure that all of theBIOS settings in the system are correct, by rebooting the system, going into BIOS setupand double-checking all the values (hopefully against a recent BIOS settings backup).
If you have created a backupcopy of your CMOS settings then use them to restore the settings to the correctvalues. To find the problem itself:

Bios checksum error. How to solve it?


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.

Ports are usually labelled - look carefully.
Try manufacturers manual.

If you have another computer download the previous BIOS update of version 3.0 and see if that works.

CMOS SETTING and BOOTING


I just had the CMOS checksum error while starting the computer, So pressed F1 and continued.. I just don't think it's the battery, because the computer is 2-3 months old, and all parts were new. I also have another problem. which is that it tells me at start upo the the IDE 80 connector cable isn't installed, or something like that, which prevents one of my hard drives to be found by windows....
