What happen if CMOS Battery Low

January 8, 2009 by @HKw@! | No Comments | Filed in PC Hardware Troubleshooting

Below are the tips to learn how to tell if a CMOS battery is low.

  1. If your computer’s clock falling behind or continually incorrect even though you might have reset the time.
  2. When the CMOS battery does get low, it will not be a crisis initially. You will have some time to open your computer and find out what replacement battery you will need.
  3. With some computer models, you will receive an error message on your screen initially at startup. This message varies by manufacturer. You may also see a prompt at start up that states “Press F1 for setup or F2 to load default values.” Know that this could vary by computer brand.
  4. Sometimes the computer will not show signs of failure at each boot up. It may be more random at first. Or, your computer may get to a certain point in the start up process and then freeze. And, rebooting does not seem to help this problem.
  5. when the battery is drained entirely, it will not be able to save any of your settings and then the CMOS will need to be replaced.
