Working on your computer

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 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

finish 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 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).

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

then unplug the cable from the network device.

3. Disconnect all network cables from the computer.

4. Disconnect your computer and all attached devices from their electrical outlets.

5. Press and hold the power button while the computer is unplugged to ground the system board.

6. Remove the cover.

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.

the power button for about 6 seconds to turn them off.

After working inside your computer

After you complete any replacement procedure, ensure that you connect any external devices, cards, and

cables before turning on your computer.

devices, power strips, and power

extension cables to verify that

the computer turns on properly.

• Ensure the electrical outlet is

working by testing it with

another device, such as a lamp.

Steady/Blinking Amber Computer fails to complete POST or

processor failure.

• Remove and reinstall any cards.

• Remove and reinstall the

graphics card, if applicable.

• Ensure the power cable is

connected to the system board

and processor.
