  1. Remove the padlock from the padlock ring, if present.

NOTICE: Do not open the cover if the computer is on the edge of a desk or table. Doing so may cause the computer to tip over and fall. Make sure that the computer is situated so that there is at least 12 inches of desk- or table-top for the cover to rest on.
NOTICE: Open the computer cover slowly to prevent damage to the system cables.
  1. Press in on the two securing buttons until the cover is free to swing up.

NOTICE: On the small mini-tower computer, to prevent damage to the system board, open the cover until it catches at a 45-degree angle. Then remove the drive data cables from the system board and open the cover to a 90-degree angle.

Closing the Computer Cover

  1. Check all cable connections, especially those that might have come loose during your work. Fold cables out of the way so that they do not catch on the computer cover. Make sure cables are not routed over the drive cage—they will prevent the cover from closing properly.

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

  3. On the small mini-tower computer, close the cover to a 45-degree angle and connect the drive data cables to the system board.

  4. Close the computer cover by pivoting the cover down toward the back of the computer and into position. Make sure that the securing buttons click into place.

  5. Replace the padlock, if required.

NOTE: After you open and close the cover, the chassis intrusion detector causes the following message to be displayed at the next computer start- up:

ALERT! Cover was previously removed.

See "Resetting the Chassis Intrusion Detector" for instructions.
