How can I reset my CMOS battery?

Here are the steps to Load or Reset Defaults for your CMOS / BIOS settings:

Method A. Load or Reset Defaults

1. Newly manufactured computers will allow users to enter the CMOS by pressing the following function key below. Enter CMOS Setup by continuously pressing any one of these during the boot:

F1, F2, Del, Esc, F10

2. When the CMOS setup open look for an option to reset the CMOS values to its default setting or look for an option to load the fail-safe defaults. Most of the CMOS setup screen has a function key to do this. Other option may have the list for the options that you can arrow over using the arrow keys and press Enter.

3. When you found the option and selected it, you will be asked if you want to load the defaults by pressing Y for yes or arrow to the yes option.

4. If you have already set the default values, remember to Save and Exit.

Method B. Resetting Configuration Data

This is another method if you have already set the default values or recently added a new hardware but did not resolve your problem. Remember that not all CMOS setup has this feature.

Advanced Option:

• If your computer has a Phoenix BIOS that has Main Advanced, Security… across the top of the screen you can have this setting by using the right arrow key to move over to Advanced. Under the Advanced, there is an option to Reset Configuration Data when you arrow down. You can change the value to No if you want to disable it or Yes to enable it. If you are done, press the F10 key and then Save and Exit CMOS setup.

PnP / PCI Configurations:

• If your computer has a PnP / PCI Configuration option, move the cursor down to this option then press Enter. You can change the Reset Configuration Data from Disabled to Enabled. If you are done with this step, press the F10 key then Save and Exit CMOS setup.

CMOS Hard Reset:

*Make sure you are aware of ESD or Electrostatic Discharge that can damage or destroy your computer or hardware components. Make sure your computer is off before doing this.

If the above mentioned steps did not help you fix the issue, you can remove the CMOS battery for 5 minutes. This will lose all the CMOS settings including password. Just remove the CMOS battery on your main board inside your CPU and wait for 5mins. After this, put the battery back and turn your computer on.

If your computer does not have a CMOS battery, you need to do a hard reset on the CMOS by using the jumper or DIP switch on the main board. If you already find the jumper, look closely for the 3 pins and the jumper will be joining the center pin to either left or right pin. Remove the jumper and then connect the center pin to the opposite pin.

I hope this help. If you are unsure of what to do, do not continue and ask for a technician to help you resolve your problem.
