Open the computer case and find the battery on the computer motherboard, verify that it will be accessible and that it can be removed. Most computers today use a coin cell CMOS battery, as shown in the image above. Tip: Some CMOS batteries may be held down by a metal clip or bar. This clip just holds the battery in place and the battery can still be removed by sliding it under the clip. Do not bend this clip to get the battery out. If you are unable to locate your CMOS battery refer to your motherboard or computer documentation or contact your computer manufacturer for additional assistance in locating it. Obtain battery information Unfortunately, most manufacturers will not list the exact type and model of your CMOS battery; therefore, once you have located the battery, note the number stamped on the battery. The part number for the battery for most computers is CR2032. Removing the battery Caution: When inside your computer make sure you're aware of ESD and all it's potential dangers. If you're computer is using a coin cell battery similar to the above example picture. Removing the battery is relatively simple. use your fingers to grab on the edge of the battery and pull it up and out of the container holding it. Some motherboards have a clip holding the battery down. If your computer has this clip you may need to use one had to move the clip up and the other hand to pull the battery out. Unfortunately, not all CMOS batteries are removable; some manufactures will only allow a replacement battery to be added. If you're not using a coin cell battery and are not able to determine how to remove it refer to your motherboard or computer documentation or contact your computer manufacturer for additional assistance in removing the battery or how to insert a new replacement battery. Users with computers that do not have removable batteries have the only option to install a new battery will most likely also need to set a jumper when adding the new battery into their computer. Insert the new battery Once you have purchased a new battery, remove the old battery (as instructed above) and replace it with the new battery. Enter CMOS values Once the battery is replaced turn on the computer and resetting the CMOS values to defaults. After the values have all been entered make sure to save the settings before exiting. Many CMOS setups allow you to press a key (such as F10) to save values and exit all in one action.
