It is also responsible for initiating POST, which is a self-check done on the system by itself. There’s no reason to clear your CMOS if everything is working properly.Will you be able to use that drive once you login to Windows? The answer is No BIOS has to detect the hard drive first since it holds all the information related to hardware settings, and then it will be detected by the operating system.BIOS hold all the information related to hardware settings, system date, and time. Maryia_K/Ĭlearing the CMOS should always be performed for a reason - such as troubleshooting a computer problem or clearing a forgotten BIOS password. Wait five minutes before reseating the battery. Locate the round, flat, silver battery on the motherboard and carefully remove it. If the battery won’t come loose, don’t force it.įirst, ensure the computer is powered off and you’re grounded so you won’t damage the motherboard with static electricity. Note: Not all motherboards have removable CMOS batteries. The CMOS battery provides power used to save the BIOS settings - this is how your computer knows how much time has passed even when it’s been powered off for a while - so removing the battery will remove the source of power and clear the settings. If your motherboard does not have a CLEAR CMOS jumper or button, you can often clear its CMOS settings by removing the CMOS battery and replacing it. Set the jumper to the “clear” position, power on your computer, turn it off again, set the jumper to the original position - and you’re done. Tip: The CMOS clear jumper almost always has three pins.Įnsure you’re grounded so you don’t damage your motherboard with static electricity before touching it. Open the computer’s case and locate the jumper named something like CLEAR CMOS, CLEAR, CLR CMOS, PASSWORD, or CLR PWD - it will often be near the CMOS battery mentioned below. Flip the computer’s power switch to the off position to ensure it’s not receiving any power. However, the basic process is fairly similar on all computers. You should consult the manual for more detailed instructions if you want to use the motherboard jumper. The exact location of the jumper can be found in the motherboard’s (or computer’s) manual. This is particularly useful if the BIOS is password-protected and you don’t know the password, or if you’ve made changes that prevent you from accessing the BIOS normally. Many motherboards contain a jumper that can be used to clear CMOS settings if your BIOS is not accessible. You’ll still need to hold it down for a few seconds to trigger a reset. CMOS buttons located on the motherboard are usually pretty clearly marked, and they aren’t usually recessed.
