You can generally run your PC without the CMOS battery as long as your default CMOS parameters are compatible with the operating system, or as long as you manually set the appropriate CMOS parameters after every time the system loses power.

What happens if you remove the CMOS battery?

Removing the CMOS battery will stop all power in the logic board ( you also unplug it too). If a computer is having boot loops or is frozen and there is no other way to restart the computer then unplugging it and taking out the CMOS battery will take out any remaining code in the RAM of the system.

Clearing the CMOS should always be performed for a reason – such as troubleshooting a computer problem or clearing a forgotten BIOS password. There’s no reason to clear your CMOS if everything is working properly.

Can you clear CMOS without Jumper?

If there is no CLR_CMOS jumpers or [CMOS_SW] button on the motherboard, please follow the steps to clear CMOS: Take out the battery gently and put it aside for about 10 minutes or longer. (Or you can use a metal object to connect the two pins in the battery holder to make them short-circuited.)

Can you clear CMOS with a screwdriver?

To clear the values of the CMOS, place a jumper cap on the two pins to shorten the two pins temporarily, or use a metal object like a screwdriver to touch the two pins for a few seconds. Always turn off your computer and unplug the power cord out of the power outlet before clearing the CMOS values.

How do you clear CMOS with a jumper?

Steps to clear CMOS using the jumper method In general, the CMOS jumper is three pins located near the battery. 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.

Do you need a CMOS jumper?
