You need to replace the cmos battery in your computer. Theu are usually Cr2032 batteries which you should be able to pick up for about £1.

unplug your computer and open the case.
When you look at the motherboard you should be able to easily locate the cmos battery cliped onto the mobo.
Take the old battery out and insert the new one.
put the case back on and plug the pc into the mains again.
You will need to re-enter the date etc the next time you boot up, but the settings should be retained after that.

Bios rom checksum error, boot block bios vI.0


Error BIOS ROM CHECKSUM - SYSTEM HALTED.
Cause Bad Hardware
Solution Unfortunately this indicates that your computer BIOS ROM chip or Motherboard is physically bad. It is recommended that you contact your computer manufacturer or take the computer into local service center for repair.
If you wish to repair this issue yourself the motherbard will need to be replaced.
This error is not the same as a CMOS Checksum Error, which refers to corrupted values of the CMOS settings, the ones you set through the BIOS setup program. This error means the contents of the BIOS code itself are damaged.

The BIOS ROM chip on the motherboard is probably faulty. It could also be another component on the motherboard.

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


If you have reset the CMOS memory you need to go into the BIOS setup screen and reconfigure the BIOS. To do that you need to press a key while the computer is booting. Usually F2 but can be other keys. It should tell you on the bottom of the first screen which key to press to enter BIOS setup.
If you don't know the settings the should be one for optimal defaults - use that one. You will also need to reset the time and date.
Save, Exit and re-boot and everything should then work.

During the boot process you will see on the screen a certain key to press to enter setup
Press and hold that key during the boot up process to enter BIOS you can load failsafe defaults or load optimized defaults ,press escape then press f10 to save to cmos to restart
You will also need to set the time and date

In the main or system setup screen you should be able to see the date and time Using your arrow keys navigate to the date and change the date. Once highlighted on the month, day, or year, press your arrow keys or your page up / page down keys to change the date.
hope this helps you

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.

How to solve CMOS checksum and timer errors?


Hello,

Your backup battery is to weak to save the cmos data. Open your computer case and look for a round silver battery that looks like a quarter. Remove it and go to Radio Shack or a drug store battery section and get a replacement. The battery number is probably CR2032 but may be CR2025 or CR2016. insert the new battery and power up your computer, this time when you set the time and date the settings will stay when you turn it off.

I hope this helps, If so please rate our solution.

Cmos checksum error defaults loaded


Make sure the battery your using is brand new. If it is then go ahead and get into the Bios and make sure the date and time is set properly. Once you do that then go ahead and save the changes and exit.

After this go ahead and see if the CMOS exit checksum defaults comes up if not then go ahead and turn off the computer and unplug it. Then after about 5 minutues plug the computer back up and turn it on and if the message doesn't come up then its resolved.

If the cmos checksum error comes back up then try a brand new battery, should be a 2032 battery and then go thru the same steps in setting the date and time and save changes and exit and if the message doesn't come back then unplug the system again and leave it unplugged for 5 minutes. Now plug it back up and if the message stays away the problem is resolved. it the message comes back then that means the motherboard isn't reconizing the batteries and the motherboard would need to be replaced.

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.

My computer went back to older clock date as 1610


try starting your computer in safe mode and see if you can do anything productive there, like scanning for viruses or spyware. also check if you can do the following:
CTRL+ALT+DEL (open task manager)
goto Start>Run>Regedit (open registry editor)
goto Start>Control Panel>Display>Properties (change display settings)
right click on clock at tray and change the current time to correct settings

if you cannot do any of these activities, then your computer may probably been compromised by a virus or malware.
