Problem with my BIOS CMOS Setting

I am having problem with my CMOS Setting, it doesn't retain any setting and I have to reset the date and time everytime I boot my system. I've changed the CMOS battery but the problem still persit. I recently flashed my BIOS to see if it will help, with no result, however I was able to bypass the BIOSTAR page and now I have a warning on the start-up page and i don't know what to do. The message read thus:
CMOS checksum error- Defaults loaded
Warning! CPU has been changed or CPU Ratio changed fail.
Please re-enter CPU settings in the CMOS setup and remember to save before quit!

Its due to your default CMOS setup does not match with your CPU configuration especially with CPU speed.

  1. To fixed the above problem goto BIOS and navigate settings of CPU, speed etc. Set the speed with the proper value as per manual. And save the settings.
  2. Infuture when you will load default, at that time also set the CPU settings.
  • The CMOS battery might not be connected properly or may be its not producing enough power as per needed by board. So have a look with another battery. Also clean the connection point of the CMOS battery.

Good Luck

HOW TO REST MOTHERBOARD AFTER CHANGING BATTERY


If you changed the CMOS battery you in effect reset it. On boot up, go into the BIOS setup and check all settings. Even if you don't change any of the BIOS settings, save them as if you did and it will reboot. Should be OK then.

Cmos checksum error-defaults loaded


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.

Make sure the battery has plenty charge or remove the battery for a while, about 5 minutes to see if that restores it some motherboards cmos batteries are soldered in

You could check the site for the machine vendor to see if there is a reset jumper.

If that doesn't work then you will need to refresh the BIOS


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 the Delete or 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.
.

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.

Press F10 Save, Exit and re-boot and everything should then work
hope this helps

P4P800 - VM BIOS Version 1012 to Upgrade 1018 Now CMOS can't save Date & Time


I'm sorry to have to say this but your CMOS battery connection is bad. There is basically nothing you can do other than replace the whole motherboard if it is too much of a problem.

One of my many computers is like this as well. I'm lucky in that as long as I leave that computer plugged in (it doesn't need to be turned on just plugged in), the CMOS won't reset its self. If you aren't that lucky then I would seek out a replacement motherboard.

ASUS P5GZ-MX: Cmos Settings Wrong - Tryed New Cmos battery and setting time a date howto fix ?


It may just be that the new battery needs to be charged. I would leave it switched on for 24 hours to check. If this doesn't fix the problem, it could also be a failing BIOS chip or the charging circuit for the CMOS battery has failed. If the BIOS chip is not socketed or the cmos charging circuit has failed, you will need to replace the motherboard or find an electronics engineer to replace the failed components, this will probably be more expensive that a new board.

Problem with BIOS. Cannot change system date.


Put all default setting on CMOS setup and then set the date by checking that the replaced one battery is energetic enough to meet the system requirement. I mean to say having 3V as it should have.

best of luck!

I have an intel g41 motherboard....every time i switchon d pc...it shows check cmos error and the time and date are set to defaluts


This error occurs when the BIOS battery is flat. Replace the BIOS battery, most motherboards use a lithium battery type CR2032, this is a coin size battery. Check the BIOS battery type used on your motherboard before you purchase the battery.
After replacing the battery go to the BIOS setting and set the Date & Time etc. and you will not have this CMOS error.

Just replacing the battery will not set anything. You have to do the setting of the values. If you can run setup by pressing F1, then do that and set all the settings and then save before exiting. Make sure you save the settings by choosing the correct exit and re-boot option.
If the settings cannot be set nor saved, then make sure the poser is off or pull the plug from the wall outlet, then short the bios with the jumper to short the bios. This will reset the bios to the default settings. Turn on the system and then go to the bios settings and set the settings. Then use the reboot option to save the settings.
