On the motherboard, even an inexperienced user can easily find a CR-2032 battery, usually located at the bottom of the board, next to the PCI slots. If your computer begins to report the CMOS battery failed error, and the operating system keeps running out of clock, then it's time to change the battery.
Necessary
- - computer system unit;
- - screwdriver;
- - vacuum cleaner;
- - small brush.
Instructions
Step 1
Remove the side cover of the system unit, which gives access to the motherboard. If the inside of your computer is dusty, pick up a paintbrush and vacuum cleaner and gently clean all circuit boards. You cannot start replacing the battery without this procedure. It is also worth considering the fact that there are small parts in the computer system unit, so you need to carefully clean all the insides.
Step 2
If the motherboard is clean, move aside the interfering cables and wires (but do not disconnect from the motherboard, otherwise you will not remember where they were later) to provide free access to the lower area of the motherboard. The battery is secured to the motherboard with a light latch - gently pry it open with a screwdriver or finger. The battery will pop out of the slot. Replace with a new battery. These batteries can be bought at any store that sells small items for the home.
Step 3
Replace the cover from the system unit and turn on the computer. Go to BIOS by pressing Del or F2 on your keyboard. Set the date and time settings, then go to the Boot section and set the boot order. Save your changes by pressing F10 and typing on your keyboard. If you fail to enter the BIOS the first time, try again.
Step 4
Verify that the BIOS settings are intact (and that the new battery is working) by unplugging the computer for a while. If after turning on everything remains as you configured, then the battery is doing its job. You usually need to change the battery no more than once every 2-3 years. However, the cases are different, so buy one battery for a reserve, so that in such cases you do not experience such complex problems in the system unit of a personal computer.
