Should i clear cmos

One reason to clear CMOS is to help troubleshoot or solve certain computer problems or hardware compatibility issues. Below are three very different ways to clear CMOS.

Any one method is as good as any other but you may find one of them easier, or whatever problem you might be having may restrict you to clearing the CMOS in a particular way. While the default settings for most modern motherboards will usually work just fine, if you've made changes yourself, like those related to overclocking, you'll have to make those changes again after resetting BIOS. The exact menu option in your particular motherboard's BIOS may differ but look for phrases like reset to default , factory default , clear BIOS , load setup defaults , etc.

Every manufacturer seems to have their own way of wording it. Finally, choose to save the settings and then restart the computer. It should be easy enough, however, as long as you can find that reset option. Start by making sure your computer is unplugged. If you're using a laptop or tablet, make sure the main battery is removed, too. Next, open up your computer's case if you're using a desktop PC, or find and open the small CMOS battery panel if you're using a tablet or laptop computer.

Every laptop is different. Some may have a small battery compartment with its own cover, but many don't. Sometimes you will need to remove the whole back cover. Finally, remove the CMOS battery for a few minutes and then put it back in. Close the case or battery panel and then plug in, or reattach the computer's main battery. By disconnecting and then reconnecting the CMOS battery, you remove the source of power that saves your computer's BIOS settings, resetting them to default.

This has nothing to do with pictures or any saved programs or files. Try disconnecting the hard drive, and power on the system. Try doing a windows repair with your OS disc. Removing the CMOS battery will allow your computer to run however, you will lose the date and time settings, the computer will boot with default BIOS settings or you will have to choose the drive that the OS is installed every time you start your computer.

The CMOS battery is not there to provide power to the computer when it is in operation, it is there to maintain a small amount of power to the CMOS when the computer is powered off and unplugged. Skip to content Android Windows Linux Apple. Home » Other.
