Removing battery

1. Follow the procedure in Before working inside your computer.
2. Remove the base cover.
3. To remove the battery:
   1. Disconnect the battery cable from the connector on the system board [1].
      NOTE The Latitude features either a 3-cell or 4-cell battery, which needs to be removed before replacing the customer replaceable unit (CRU) parts. Therefore, when performing any disassembly procedure, the battery connection must be disconnected immediately after removing the bottom cover. This procedure is required to disconnect all power sources from the system and to prevent the system from accidentally switching on and shorting the components.
   2. Remove the two (M2.0 x 5.0) screws that secure the battery to the computer [2].
      NOTE A 3-cell battery has a single screw, and a 4-cell battery has two screws. Hence, the image displayed below is a 4-cell battery.
   3. Lift the battery from the system [3].
