You need to setup your CMOS again. To do that you have to turn on your computer and on that few seconds hit the (depending on your mobo type) it could be the DEL or F2 or F10 or any other keys to open up the CMOS setup page. From there you can set your date, time and so on. Then save it and system will restart and you back on business.

Main Bios Checksum Error!!!


Take notes of the BIOS settings of your computer for use after replacing the CMOS battery.

To access the computer's BIOS, restart your computer and press the "F 10" function key during the restarting process.


The BIOS configuration panel will then open and you can write the specific settings for your computer down to use for BIOS configuration after replacing the battery.


Turn off your computer and remove the power cable and if installed, battery.

Remove the computer hatch which will vary in method depending on the brand and model of computer you have.


On some motherboards cmos batteries are soldered in


Locate the CMOS battery on the motherboard.

The more popular model of CMOS battery used is annotated with a CR2032 label and is a round shaped button.


Firmly remove the CMOS battery from the motherboard.

Align the new CMOS battery with the positive side orientated towards you and insert into the mother board.


Restore the power cables to your computer and restart the PC.

During the restarting process, depress the "F10" function key to enter the BIOS setup screen.


Update the date in the BIOS and change the BIOS settings to match those you recorded in step one.


After the settings are updated, select the "Save and Quit" menu option and restart your computer to finish the CMOS battery replacement.


hope this helps

Intel bios supervisior pass reset with open system case


BIOS Password is stored in CMOS and retained by power provided by the CMOS (Coin-cell) Battery.
To Reset the BIOS Password, Remove the CMOS (Coin-cell) Battery from the motherboard for five minutes and restart the system. This will load the factory default settings and the password would be gone. Re-install the battery after the password is rest.

GoodLuck!

"Reset you're cmos/bios jumper to


HI,
No need to worry. There are many known ways to reset / remove / bypass the password:
  • By removing the CMOS battery
  • By using the motherboard jumper
  • By using MS DOS command
  • By using software
  • By using Backdoor BIOS password
Now I'll try to explain each method one by one:
A. By Removing the CMOS Battery:
xrojer_2.jpg
Almost all motherboards use a small coin sized CMOS battery to store all BIOS settings along with the password. To reset the password, unplug the PC, open the cabinet and remove the CMOS battery for approx. 15-30 minutes and then put it back. It'll reset all BIOS settings as well as the password and you'll need to re-enter all settings.
If it fails, then try to remove the battery for at least one hour.

B. By Using the Motherboard Jumper:
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.

C. By Using MS DOS Command:
This method works only if you have access to the system when its turned on because this method requires MS DOS. Open Command Prompt from Programs menu and provide following commands one bye one:
debug
o 70 2E
o 71 FF
quit
NOTE: The first character in the above commands is "O" and not the number 0.
After providing the above commands, restart your system and it should reset the CMOS Settings along with the BIOS password.
If you are curious to know how it works? then let me explain the above commands:
In this method we are using the Debug tool of MS DOS. The "O" character present at first in these commands, outputs the values to IO ports. The number 70 and 71 are port numbers which are used to access CMOS memory. By providing FF value we are telling CMOS that there is an invalid checksum and it resets the CMOS settings as well as BIOS password.

Checksum error


Hi Oliver, the most common error related to the message,
(Bios Rom Checksum Error). Someone has left a floppy disk in the floppy drive. Once the floppy disk has been removed press the reset button on the PC, your windows will start normally. Next place to look is in your bios.
Open your manual to page 27.
Enter your bios & go to the title Advanced BIOS Features. Check First, Second & Third boot devices they should be as follows. Floppy disk drive, CD-ROM drive & primary hard disk drive. If both of the above are ok than try clearing the cmos/bios by resetting the cmos jumper (JP1) location on page 5. Descriptions of page five on page 6. CMOS settings on page 9.
When your system restarts re-enter your cmos & reset up your bios settings. Lastly if none of the above has fixed the error message, than remove the cmos battery & check its voltage. It should maintain 3volts. If yours' is lower than 3volts replace the cmos battery. There is one other possible fix. It’s an option not given lightly. Flashing a cmos/bios is not recommended unless all other options have failed.

CMOS/GPNU Checksum Bad 0085


You may have a bad CMOS battery. Does it do this on restarts as well as cold boots.....if you only receive this message on cold boots, then you have a dead battery.

Check cmos error


Read this only if you are sure that you have replaced the correct type of battery & you have set the jumpers to the default locations.

It is not the problem with the battery or the charging problem (Actualy CMOS battery is not Recharable )..in most cases.

The problem is the battery holder in mainboard where we put the battery IN. eventualy or accidently these Pins from the Battery Holder are made loose or not contacted with the battery.i had the same problem and the solution was to adjust the Battery holder to seat the battery in proper way.
