The motherboard battery, commonly referred to as the CMOS battery, is a small but essential component in your computer. It powers the CMOS (Complementary Metal-Oxide-Semiconductor) chip, which stores BIOS settings, system time, and hardware configuration when the computer is powered off.
Turn off your computer, unplug it, and open the case. Locate the small, round CMOS battery on the motherboard. Refer to your motherboard manual if you’re unsure. Carefully remove the old battery using your fingers or a non-conductive tool. Note its orientation (positive and negative sides).
If your laptop has a non-removable battery, skip this step. Desktop users can remove the power cable. Now, press and hold the power button for 30 to 45 seconds. Now, check if you can turn on your computer. It is important to install the CMOS battery in the right polarity. Otherwise, the battery will not work.
As you have removed the CMOS backup battery, your BIOS settings have been lost and you will need to restore them. Except in the case where the default BIOS settings were fine, your computer will not boot until you do that. Press the key to enter BIOS setup during boot, and review your BIOS settings and set any that are incorrect.
Desktop users can remove the power cable. Now, press and hold the power button for 30 to 45 seconds. Now, check if you can turn on your computer. It is important to install the CMOS battery in the right polarity. Otherwise, the battery will not work. If you install the battery in the wrong polarity, you may also experience booting issues.
You need not reset your BIOS after changing or replacing the CMOS battery because your settings are already reset to default. When we remove a CMOS battery, the BIOS settings automatically reset to the default. This is because removing the CMOS battery terminates the power supply to the BIOS chip.
