Cover

To remove the computer cover, perform the following steps.

NOTICE: To avoid inadvertently damaging the system board, be sure you that disconnect the system from the electrical outlet,

disconnect the power cable from the back of the chassis, and press the power button before removing the computer cover. This

system continues to receive a small amount of power when the system is turned off and attached to an electrical outlet (the system-

board power indicator is on when power is detected).

1. Face the front of the chassis. Place your left hand on the left side of the chassis. Push back the release latch at the top back edge of the

chassis to release the computer cover into your left hand.

2. Lift the cover out from the curves at the bottom of the chassis.

CAUTION: To prevent cuts, keep your hands clear of the metal edges on the chassis and fan guard as you slide the

cover back.

To replace the computer cover, perform the following steps:

1. Check all cable connections, especially those that might have come loose during your work. Fold cables and unused connectors out of the

way so that they do not catch on the computer cover or interfere with airflow inside the computer.

2. Check to see that no tools or extra parts (including screws) are left inside the computer.

3. Place the chassis upright with the front facing you. Align the computer cover so that its bottom hooks fit in the chassis curves.

4. Lift up the cover, making sure to keep the bottom hooks aligned with the curves in the chassis.

5. Gently squeeze the right and left sides of the computer together until the cover clicks into position.
