If the battery dies or is removed, then when your computer boots it will have forgotten the current date and time. I think of it as a glorified watch battery. Plug the computer and all devices back in. The purpose of the CMOS battery most often today is simply to allow your computer to remember what time it is.Wait 1–5 minutes, then reconnect the battery.If the battery is connected to an onboard header with a wire, disconnect the wire from the onboard header.

If the battery is in a holder, note the orientation of the + and – on the battery. Gently pry the battery free from its connector.The battery may be in a horizontal or vertical battery holder, or connected to an onboard header with a wire. Disconnect the power cord from the AC power source.Turn off all peripheral devices connected to the computer.Steps to clear CMOS using the battery method In some systems, you might need to enter BIOS to reset to the factory defaults. In general, CMOS jumper has positions 1–2 and 2–3. Move the jumper from the default position 1–2 to position 2–3 to clear CMOS. Wait 1–5 minutes then move it back to the default position.In general, the CMOS jumper is three pins located near the battery.

Locate the CMOS jumper by referring to the motherboard manual and how to clear the CMOS.Open up the system so you can see the motherboard.Steps to clear CMOS using the jumper method See steps for the two methods listed below.

The jumper position, time to wait, and location of the jumper are completely dependent on the motherboard.

Using a CMOS jumper or a dedicated jumper on the motherboard, generally near the battery.

The BIOS is also used to identify and configure hardware in the computer.įor no boot or no display issues, clearing CMOS may help recover the boards because that restores the BIOS default settings. It instructs the computer on how to perform a number of basic functions such as booting and keyboard control.
