outlets.

4 Disconnect all cables such as telephone cables, network cables and so

on, from your computer.

WARNING: Before working inside your computer, read the safety

information that shipped with your computer. For more safety best

practices, see the Regulatory Compliance home page at dell.com/

WARNING: Disconnect all power sources before opening the

computer cover or panels. After you finish working inside the

computer, replace all covers, panels, and screws before connecting to

safety precautions, working inside your computer, and protecting

against electrostatic discharge.

CAUTION: Before touching anything inside your computer, ground

yourself by touching an unpainted metal surface, such as the metal at

the back of the computer. While you work, periodically touch an

unpainted metal surface to dissipate static electricity, which could

harm internal components.

CAUTION: When you disconnect a cable, pull on its connector or on

its pull-tab, not on the cable itself. Some cables have connectors with

locking tabs or thumb-screws that you must disengage before

disconnecting the cable. When disconnecting cables, keep them
