Often, desktop computer owners are surprised to learn that their computers have batteries. After all, a desktop computer is not portable. However, desktop computers save certain custom settings such as the date and time on a small memory chip that requires a small charge to be applied in order to retain those settings when the computer is turned off. The Dell Dimension 8300 is no exception to this, and if you receive a message when turning the computer on about the voltage of the motherboard battery being low--or constantly have to re-input settings when turning the computer on--it is time to change the battery.

Skill level:
Moderately Easy

Things you need

  • 3-volt CR2032 lithium coin-cell battery

  1. 1

    Turn the Dimension 8300 off. Touch a grounded metal object to dissipate built-up static electricity from your body, then remove the power cable and move the Dimension 8300 tower to a desktop or table that can support its weight. Place the Dimension 8300 tower on its side so that the side with a Dell logo faces the ceiling. You will also notice an arrow on one side of the computer that should face up.

  2. 2

    Push the two oval-shaped buttons on the top and bottom of the Dimension 8300 tower. While holding both buttons in, swing the side panel of the Dimension 8300 tower up to open the computer. If you have difficulty, you can lift with one hand while pushing a button with the other hand, and after lifting one end of the side panel, switch to the other button.

  3. 3

    Grasp both sides of the existing coin-cell battery with your finger and thumb, and wiggle gently to free the battery from its receptacle. If necessary, use a non-metal tool to pry the battery out.

  4. 4

    Push the replacement battery into the receptacle with the positive side--marked by a plus sign--facing up.

  5. 5

    Lower the side panel of the Dimension 8300 into its original position. When the computer tower is fully closed, the side buttons will click.
