Working on Your Computer 1

Before Working Inside Your Computer

Use the following safety guidelines to help protect your computer from potential

damage and to help to ensure your personal safety. Unless otherwise noted,

each procedure included in this document assumes that the following

conditions exist:

• You have performed the steps in Working on Your Computer.

• 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: 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 certified 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.

NOTE: The color of your computer and certain components may appear differently

than shown in this document.

To avoid damaging your computer, perform the following steps before you begin

working inside the computer.

1. Ensure that your work surface is flat and clean to prevent the computer

cover from being scratched.

2. Turn off your computer (see

Turning Off Your Computer

3. If the computer is connected to a docking device (docked) such as the

optional Media Base or Battery Slice, undock it.

CAUTION: To disconnect a network cable, first unplug the cable from your

computer and then unplug the cable from the network device.

4. Disconnect all network cables from the computer.

5. Disconnect your computer and all attached devices from their electrical

outlets.

6. Close the display and turn the computer upside-down on a flat work

surface.

NOTE: To avoid damaging the system board, you must remove the main battery

before you service the computer.

7. Remove the main battery.

8. Turn the computer top-side up.

9. Open the display.

10. 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 display.

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.

11. Remove any installed ExpressCards or Smart Cards from the appropriate

slots.
