The figure above shows the sequence to remove a compartment door. Two quarter-turn latches are used to secure each
compartment door to the computer. The removal of both the battery and disk compartment doors is shown.
To remove a compartment door follow these steps:
1. The two quarter-turn latches on the compartment door can be secured with optional M2 screws. If the screws
are present, remove them using a #1 Philips screw driver. If not, proceed to step 2.
2. Lift the handle on the latch.
3. Turn the latch a quarter-turn in the direction of the 'unlock' icon.
4. Lift the compartment door away from the system.
5. Reverse this procedure to replace and secure the compartment door.
