Removing the Front Bezel
1. Remove/disengage any security devices that prohibit opening the computer.
2. Remove all removable media, such as diskettes or compact discs, 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. Remove the computer access panel.
CAUTION After removing the access panel, look for the LED on the system board to the
right of the DIMM sockets. If the LED is illuminated, the system still has power. Turn off the
computer and remove the power cord before proceeding.
6. To remove the front bezel, press down on all three tabs on the left side of the bezel (1) then rotate
the bezel off the chassis (2), beginning with the left side then the right side.
