 CAUTION: Before performing any of the procedures in this section, follow the 

safety instructions in the System Information Guide.

1

Shut down the computer through the Start menu.

Ensure that your computer and attached devices are turned off. If your computer and 
attached devices did not automatically turn off when you shut down your computer, 
turn them off now.

 NOTICE: To disconnect a network cable, first unplug the cable from your computer and then 

unplug it from the network wall jack.

Disconnect any telephone or telecommunication lines from the computer.

4

Disconnect your computer and all attached devices from electrical outlets, and then 
press the power button to ground the system board.

 CAUTION: To guard against electrical shock, always unplug your computer from 

the electrical outlet before opening the cover.

(1 ft) of desktop space.

Open the computer cover.

–

For the mini-tower, push the buttons on both ends and lift the cover open.

For the desktop, slide the cover release latch toward the power supply of the 
computer. Raise the cover, and pivot it toward the front of the computer.

Ground yourself by touching an unpainted metal surface on the computer, such as the 
metal at the back of the computer, before touching anything inside your computer.

While you work, periodically touch any unpainted metal surface on the computer to 
dissipate any static electricity that could harm internal components.
