Your BIOS settings are not corrupted. The CMOS cell is not memorizing your settings after you reboot it. So you must change the CMOS battery. My humble request to buy a qualitative CMOS battery so that battery can work as guarantee. Thanks for using FixYa.

Hello Friend,

There are a few ways.
The easiest way is to enter the BIOS setup screen, and select the option to reset to default settings, it should be easy to find or it would be on the save changes sections.

If you can not access the BIOS setup screen, it will take physical access to the computer's motherboard. This means you will need to open up the computer case. From here there are a few options that you can do.
change the the CMOS jumper to reset.
Press the CMOS reset buttion
Or remove the CMOS battery for a few minutes.
Please note that not all manufacturer have a jumper setting or cmos reset button. Also a CMOS battery looks like a button battery.
Also if you are going to open up the case, make sure the computer is off, unplugged, and if this is a laptop the battery must be removed. Good Luck!

CMOS Coin-cell is located under the keyboard. You have to remove the hinges cover and keyboard to access the coin -cell

the cmos battery will most likely be a 3volt coin cell battery. it has a part number of CR2032. 90% of all pc's use this battery as the cmos battery and can be purchased just about anywhere. here are some pictures of the battery although it can be in a different location on your particular motherboard.

Opem back side cover of laptop.
You find 1 motherbord chipset there.
On motherbord you find cmos cell .

you need to change your cmos cell on motherbord circuit for that open back side cover and then you can see cmos cell on motherbord circuit.Change it pur chase new cmos cell.
Your old cmos cell has not enough waltage so your bios settings are not saved when you turn off the power.

Just change your CMOS battery with a new one and after that goto the bios settings and update the time and dare.
After that just save the settings and then check that the warning message is coming or not.

If its coming then it means you need to change the CMOS jumper settings.
