On the off chance that your PC is losing its chance or date settings, or you are accepting a message CMOS Read Error, CMOS Checksum Error, or CMOS Battery Failure, the CMOS battery should be supplanted. To do this, take after the means beneath.
Find your CMOS battery
Alert: When inside your PC, ensure you know about ESD and its threats.
CMOS battery
Open the PC case and discover the battery on the PC motherboard. Confirm that it is open and can be expelled. Today, most PCs utilize a coin cell CMOS battery, similar to the CR2032 battery.
Tip: Some CMOS batteries might be held around a metal clasp or bar. This clasp just holds the battery set up and the battery can in any case be expelled by sliding it out from under the clasp. Try not to twist this clasp to get the battery out, as a bowed clasp can bring about the battery not remaining in the battery attachment.
On the off chance that you can't find your CMOS battery, allude to your motherboard or PC documentation or contact your PC maker for extra help with finding it.
Note: With a few PCs, you may need to detach links, evacuate drives, or expel different parts of the PC to get full access to the CMOS battery.
Get battery data
Sadly, most producers don't list the correct kind and model of your CMOS battery. It is suggested that, once you have found the battery, record all data about the battery (Voltage, science, wiring, and bundling). In the event that conceivable, expel the battery and take it to the retail store.
Tip: For most PCs, the model or part number for this battery is CR2032.
Expelling the battery
In the event that your PC is utilizing a coin cell battery, evacuating the battery is generally straightforward. Utilize your fingers to snatch on the edge of the battery and haul it up and out of the attachment holding it set up. Some motherboards have a clasp holding the battery down. In the event that your PC's motherboard has this clasp, you may need to utilize one hand to move the clasp up and the other hand to haul the battery out.
Alert: When inside your PC, ensure you know about ESD and all its potential threats.
Tragically, not all CMOS batteries are removable. A few makers just enable a substitution battery to be included. In the event that your PC does not have a coin cell battery, allude to your documentation or contact your PC producer for promote help.
In the event that your PC's motherboard does not have a removable battery, you have to set a jumper on the motherboard to introduce the new battery.
Embed the new battery
Subsequent to acquiring another battery, evacuate the old battery and supplant it with the new battery or embed the new battery into the auxiliary battery attachment on the motherboard.
Enter CMOS esteems
Once the battery is supplanted, turn on the PC and reset the CMOS esteems to the defaults. After the qualities have all been entered, make a point to spare the settings previously leaving. Numerous CMOS setups enable you to press a key, (for example, F10) to spare qualities and leave across the board activity.
Awful equipment
On the off chance that you keep on receiving the blunder subsequent to following all the above advances, this is an indication of a more major issue. The in all probability causes are a terrible power supply or awful motherboard. You may need to investigate supplanting the power supply or the motherboard to determine the issue.
We prescribe taking your PC to a PC repair shop to have them analyze the issue and test the power supply and motherboard to decide whether both of them should be supplanted.
