When Working Inside Your Computer

Before you remove the computer cover, perform the following steps in the
sequence indicated.
NOTICE: Do not attempt to service the computer yourself, except as
explained in your online Dell documentation or otherwise provided to you.
Always follow installation and service instructions closely.
CAUTION: There is a danger of a new battery exploding if it is
incorrectly installed. Replace the battery only with the same or
equivalent type recommended by the manufacturer. Discard used
batteries according to the manufacturer's instructions.
Turn off your computer and any peripherals.

Ground yourself by touching an unpainted metal surface on the
2
chassis, such as the metal around the card-slot openings at the back of
the computer, before touching anything inside your computer.
While you work, periodically touch an unpainted metal surface on the
computer chassis to dissipate any static electricity that might harm
internal components.
Disconnect your computer and peripherals from their power sources.

Also, disconnect any telephone or telecommunication lines from the
computer.
Doing so reduces the potential for personal injury or shock.
