Precautionary Measures

CAUTION: Before you remove the computer cover, perform the

following steps in the sequence indicated.

Turn off your computer and any devices. Disconnect your computer and devices from their power sources. Also,

disconnect any telephone or network lines from the computer.

Doing so reduces the potential for personal injury or shock.

2 If you are disconnecting a device from the computer or are removing a

component from the system board, wait 10 to 20 seconds after disconnecting the computer from AC power before disconnecting the device or removing the component to avoid possible damage to the system board.

3 Wear a wrist grounding strap, and clip it to an unpainted metal

surface, such as the padlock loop on the back of the chassis. If a wrist grounding strap is not available, touch any unpainted metal surface on the back of the computer or on the computer chassis, such as the power supply, to discharge any static charge from your body before touching anything inside the computer. While you work, periodically touch an unpainted metal surface on the computer chassis to dissipate any static electricity that might harm internal components. Also avoid touching components or contacts on a card and avoid touching pins on a chip.

4 Verify that the standby power light on the system board is not on. If it

is on, you may need to wait 10 to 30 seconds for it to go out.

Microprocessor Installation Guidelines

• A voltage regulator module (VRM) must be installed for each microprocessor installed. To locate the VRM and microprocessor sockets, see "System Board Components" or "Interior Service Label" in your User’s Guide.

• For single-processor operations, the processor must be installed in socket 0 and the VRM must be installed in connector 0. Processor

socket 1 and VRM connector 1 must be empty. To locate these components, see "System Board Components" or "Interior Service Label" in your User’s Guide .

• For dual-processor operations, both processor sockets and both VRM connectors must be populated.

• For dual-processor operations, the two processors and the two VRMs must be identical. If the processors do not match, you receive a system message, the diagnostic lights indicate an error, and the computer may not start. If the VRMs do not match, the diagnostic lights will indicate an error.

• If installing a Dell™ processor upgrade kit for either single or dual processors, remove and discard the original VRM(s). Then install the VRM(s) from the upgrade kit. If you are not installing a processor upgrade kit from Dell, reuse the original VRM(s).

• If installing a Dell processor upgrade kit for either single or dual processors, remove and discard the original heat sink(s) and securing clips. Then install the heat sink(s) and securing clips from the upgrade kit. If you are not installing a processor upgrade kit from Dell, reuse the original heat sink(s) and securing clips.

Upgrading the Microprocessor(s)

. NOTE: Dell recommends that only a technically knowledgeable person

perform this procedure.

CAUTION: The processor can get very hot during normal

operation. Be sure that the processor has had sufficient time to cool before you touch it.

CAUTION: Before you perform this procedure, see “Precautionary

Measures."

NOTICE: Before disconnecting a device from the computer, wait 10 to

20 seconds after disconnecting the computer from its electrical outlet. Before removing a component from the system board, verify that the standby power light on the system board has turned off. To locate this light, see "System Board Components" or "Interior Service Label"

Remove the microprocessor airflow shroud:

a Lay the computer on its right side. b Open the computer cover. c Press down and back on the indentations at the top corners of the

shroud. The top anchor tabs will disengage from the chassis anchor slots.

NOTE: If you are upgrading your microprocessor, you may want to keep

the original microprocessor, heat sink, and securing clips for future troubleshooting.

NOTE: Your microprocessor upgrade kit should include a replacement

microprocessor, heat sink, and two replacement securing clips.

Remove the microprocessor from its connector.

Your microprocessor uses a zero insertion force (ZIF) socket with a lever-type handle that secures or releases the microprocessor.

NOTICE: When you place the microprocessor in the socket, ensure that the

microprocessor aligns properly with the socket. To avoid damage, you must position the microprocessor correctly in the socket.

b Align pin 1 of the new microprocessor with pin 1 of the socket.

5 Install the replacement microprocessor heat sink:

NOTICE: Remove the film covering only when you are ready to replace the

heat sink. Once the film covering has been removed, lay the heat sink down with the thermal grease facing upward. Do not lay the heat sink down with the thermal grease touching the work surface.

a Remove the film covering the thermal grease on the bottom of the

heat sink.

NOTICE: Carefully align the heat sink with the retention base before making

contact with the base to help avoid spreading the thermal grease to other components.

b Lower the heat sink to the microprocessor so that the heat sink fits

in the heat sink retention base.

c For each of the replacement metal clips that secure the heat sink

to the microprocessor, fit the end of the clip that does not have the latch to the heat sink retention base. Then, press down on the clip’s latch to secure the clip to the heat sink retention base (see "Removing the Microprocessor Heat Sink").

6 Install the airflow shroud:

a Insert the bottom anchor tabs of the shroud into the chassis

anchor slots.

b Press the shroud toward the chassis until the top anchor tabs on

the shroud snap securely into place. See "Removing the Microprocessor Airflow Shroud."

7 Close the computer cover.

8 Stand the computer upright.

9 Reconnect the computer to the electrical outlet, and turn it on.

NOTE: If enabled, the Chassis Intrusion option will cause the following

message to be displayed at the next system start-up:

ALERT! Cover was previously removed.

Enter system setup, and confirm that the correct microprocessor speed

appears in the top left corner of the screen. Also, confirm that the top line in the System Data area correctly identifies the new microprocessor.

11 Exit system setup, turn off the computer, and attach the devices to the

computer and electrical outlets.
