Working on your computer

Safety instructions

Use the following safety guidelines to protect your computer from potential damage and to ensure your personal safety. Unless otherwise

noted, each procedure included in this document assumes that the following conditions exist:

• You have read the safety information that shipped with your computer.

• A component can be replaced or, if purchased separately, installed by performing the removal procedure in reverse order.

WARNING: Disconnect all power sources before opening the computer cover or panels. After you nish working inside the

computer, replace all covers, panels, and screws before connecting to the power source.

WARNING: Before working inside your computer, read the safety information that shipped with your computer. For additional

safety best practices information, see the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance

CAUTION: Many repairs may only be done by a certied service technician. You should only perform troubleshooting and simple

repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage

due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came

with the product.

CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an

unpainted metal surface, such as a connector on the back of the computer.

CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its

edges or by its metal mounting bracket. Hold a component such as a processor by its edges, not by its pins.

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; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the

cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a

cable, ensure that both connectors are correctly oriented and aligned.

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.

12 Remove any installed ExpressCards or Smart Cards from the appropriate slots.
