Before Working Inside Your Computer

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

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: 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 your 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 module by its edges, not by its pins.

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

computer. Damage due to servicing that is not authorized by Dell™ is not covered
by your warranty.

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

you begin working inside the computer.

1

Ensure that the work surface is flat and clean to prevent the computer cover from being scratched.

2

Turn off your computer (see "Turning Off Your Computer" on page 9).

3

If the computer is connected to a docking device (docked), undock it. See the documentation that came with your docking device for instructions.

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 telephone or network cables from the computer.

5

Press and eject any installed cards from the ExpressCard slot or the 3-in-1 Media Card Reader.

10 Before You Begin

6

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

CAUTION: To help prevent damage to the system board, remove the main battery

Processor Fan and Heat Sink Assembly

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.

WARNING: If you remove the processor fan and heat sink assembly from the

computer when the heat sink is hot, do not touch the metal housing of the heat
sink.

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 your computer).

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

computer. Damage due to servicing that is not authorized by Dell™ is not covered
by your warranty.

CAUTION: To help prevent damage to the system board, remove the main battery

(see "Removing the Battery" on page 13) before working inside the computer.

CAUTION: To help prevent damage to the system board, remove the main battery

(see "Removing the Battery" on page 13) before working inside the computer.

CAUTION: To avoid damage to the processor module, hold the screwdriver such

that it is perpendicular to the processor module when turning the cam screw.

1

Follow the procedures in "Before You Begin" on page 9.

2

Remove the base cover (see "Removing the Base Cover" on page 33).

3

Remove the processor fan and heat sink assembly (see "Removing the Processor Fan and Heat Sink Assembly" on page 39).

CAUTION: To prevent intermittent contact between the ZIF-socket cam screw

and the processor module when removing or replacing the processor module,
press to apply slight pressure to the center of the processor module while turning
the cam screw.

4

To loosen the ZIF socket, use a small flat-blade screwdriver and rotate the ZIF-socket cam screw counterclockwise until it comes to the cam stop.

CAUTION: To ensure maximum cooling for the processor module, do not touch the

heat transfer areas on the processor module thermal-cooling assembly. The oils in
your skin can reduce the heat transfer capability of the thermal pads.

CAUTION: When removing the processor module, lift the processor module

straight up. Be careful not to bend the pins on the processor module.

5

Lift the processor module from the ZIF socket.

Replacing the Processor Module

NOTE: If a new processor module is installed, you will receive a new thermal-

cooling assembly, which will include an affixed thermal pad, or you will receive a
new thermal pad along with documentation to illustrate proper installation.

1

Follow the procedures in "Before You Begin" on page 9.

2

Align the pin-1 corner of the processor module with the pin-1 corner of the ZIF socket, then place the processor module.

44 Processor Module

NOTE: The pin-1 corner of the processor module has a triangle that aligns with the

triangle on the pin-1 corner of the ZIF socket.

When the processor module is properly seated, all four corners are aligned
at the same height. If one or more corners of the processor module are
higher than the others, the processor module is not seated properly.

CAUTION: To avoid damage to the processor module, hold the screwdriver

perpendicular to the processor module when turning the cam screw.

3

Tighten the ZIF socket by turning the cam screw clockwise to secure the processor module to the system board.

4

Replace the processor fan and heat sink assembly (see "Replacing the Processor Fan and Heat Sink Assembly" on page 41).

5

Replace the base cover (see "Replacing the Base Cover" on page 34).
