It money the CMOS battery is dead ,this is the motherboard battery-operated that keeps the BIOS settings when the computer is turned off. The biggest problem is that it shows the wrong time and date so when you start the computer the operating system will enjoy the wrong date and time.This will cause the antivirus to fail to contact the server to download updates and window updates as well
Motherboards come near batteries, usually replaceable lithium coin cells. These battery are in place primarily to keep the time/date clock running and carry on BIOS setup program settings. The batteries usually last at least possible six years. If a computer loses its BIOS settings and time/date memory every time it is shut down, you’ll need to replace the battery, first. The POST might show an error message if the battery has died. Moreover, if someone have set a supervisor password in the setup program, and now have forgotten it, and the computer cannot boot, the only way to reset or undo the password is to remove and replace the battery. You might be able to use a mobile tester to test the voltage of the battery in need removing it. Make sure the polarity of the probes matches the polarity of the battery, and check to see if the freestyle is still good. Double-check the motherboard documentation to make sure the battery-operated is the right type.
Battery Replacement
If the BIOS settings are still valid and you need to replace the battery, know that the motherboard might enjoy a capacitor that will hold a charge just long enough for you to replace the freestyle without losing your settings. However, whether or not it has such a capacitor, it is recommended to write down adjectives non-default BIOS settings before changing the freestyle. Changing a replaceable battery is a simple but delicate operation. Carefully remove the feeble battery and insert the new one. Source(s): The A+ Certification and PC Repair Handbook
