Preparing to Work Inside the

Computer

NOTICE: Only a certified service technician should perform repairs on your

computer. Damage or inoperability due to servicing not authorized by Dell is

not covered by your warranty.

HINT: Unless otherwise

noted, each procedure in

this document assumes

that a part can be

replaced by performing

the removal procedure in

reverse order.

NOTICE: To dissipate any static electricity while you work, periodically touch

an unpainted metal surface on the surface of the computer, such as the I/O

panel on the back of the computer chassis.

NOTICE: Handle components and cards with care. Do not touch the

components or contacts on a card. Hold a card by it edges or by its metal

mounting bracket. Hold a component such as a microprocessor by its edges,

not by its pins.

1 To avoid damaging the computer, perform the following steps before

you begin working inside the computer.

2 Make sure that the work surface is clean to prevent scratching the

computer cover.

3 Save any work in progress and close all open programs.

HINT: Make sure the

computer is turned off and

not in standby or

hibernate mode. If you

cannot shut down the

computer using the

computer’s operating

system, press and hold the

power button for 4

seconds.

4 Turn off the computer and all attached devices.

5 Make sure the computer is not connected to a port replicator.

6 Disconnect the computer from the electrical outlet.

NOTICE: To avoid possible damage to the system board, wait 10 to 20

seconds before you disconnect any attached devices.

7 Disconnect all external cables and attached devices from the

computer.

8 Remove any installed PC Cards or plastic blanks from the PC Card

slot.

9 Close the display and turn the computer upside down on a flat work

surface.

10 Remove the battery from the battery bay.

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

before you service the computer.

11 Remove any installed device in the media bay.

• Pry stick

• Small plastic scribe

• Microprocessor extractor

• Flash BIOS update program floppy disk or CD (required only when

Screw Identification

Before removing and replacing components, photocopy the screw placemat

as a tool to help keep track of the screws. The placemat provides the

number of screws and the sizes.

NOTICE: When reinstalling a screw, you must use a screw of the correct

diameter and length. Make sure that the screw is properly aligned with its

corresponding hole, and avoid over tightening.
