Safety First—For You and Your Computer
The procedures in this section require that you remove the cover and work inside your computer. While working inside your computer, do not
attempt to service the computer except as explained in this guide and elsewhere in Dell documentation. Always follow the instructions closely.
Working inside your computer is safe—if you observe the following precautions.
Before you start to work on the computer, perform the following steps in the sequence indicated:
1. Turn off the computer and all peripherals.
2. Touch an unpainted metal surface on the computer chassis, such as the metal around the card-slot openings at the back of your computer,
before touching anything inside your computer.
3. Disconnect the computer and peripherals from their electrical outlets. Doing so reduces the potential for personal injury or shock. Also
disconnect any telephone or telecommunication lines from the computer.
While you work, periodically touch an unpainted metal surface on the computer chassis to dissipate any static electricity that might harm
internal components.
In addition, Dell recommends that you periodically review the safety instructions in your System Information Guide.
