Removing the computer access panel
To access internal components, you must remove the access panel:
1. Remove/disengage any security devices that prohibit opening the computer.
2. Remove all removable media, such as compact discs or USB flash drives, from the computer.
3. Turn off the computer properly through the operating system, then turn off any external devices.
4. Disconnect the power cord from the power outlet and disconnect any external devices.
CAUTION: Regardless of the power-on state, voltage is always present on the system board
as long as the system is plugged into an active AC outlet. You must disconnect the power cord
to avoid damage to the internal components of the computer.
5. Lift up on the access panel handle (1), slide the computer back approximately 12 mm (1/2 inch)
(2), and then lift the access panel off the computer (3).
