Information Update on Processor Installation
Removing a Processor
WARNING: Only trained service technicians are authorized to remove the system
cover and access any of the components inside the system. Before you begin this
procedure, review the safety instructions that came with the system.
1 Prior to upgrading your system, download the latest system BIOS version
from support.dell.com and follow the instructions included in the
compressed download file to install the update on your system
.
2 Turn off the system, including any attached peripherals, and disconnect
the system from the electrical outlet. When disconnected from AC power,
press and hold the power button for 3 seconds to fully drain the system of
stored power prior to removing the cover.
NOTE: It is recommended that you always use a static mat and static strap while
working on components in the interior of the system.
3 Open the system. See "Opening the System" in the Hardware Owner’s
Manual
.
4 Remove the cooling shroud. See "Removing the Cooling Shroud" in
the
Hardware Owner’s Manual .
WARNING: The heat sink and processor are hot to the touch for some time after
the system has been powered down. Allow the heat sink and processor to cool
before handling them.
CAUTION: Never remove the heat sink from a processor unless you intend to
remove the processor. The heat sink is necessary to maintain proper thermal
conditions.
5 Release one of the heat-sink release levers or remove the screws from
the corners of the heat sink. See your
Hardware Owner’s Manual for a
system-specific illustration. See Figure 1-1.
6 Wait 30 seconds for the heat sink to loosen from the processor.
7 Release the other heat-sink release lever.
8 Gently lift the heat sink off of the processor and set the heat sink aside
upside down (thermal grease side facing up).

4Processor Installation
Figure 1-1. Installing and Removing the Heat Sink
CAUTION: The processor is held in its socket under strong pressure. Be aware
that the release lever can spring up suddenly if not firmly grasped.
9 Position your thumb firmly over the processor socket-release lever and
release the lever from the locked position by pushing down and pulling out
from under the tab. Rotate the lever 90 degrees upward until the processor
is released from the socket. See Figure 1-2.
10 Use the tab on the processor shield to rotate shield upward and out of
the way. See Figure 1-2.

NOTE: Your heat sink may appear differently than the one shown above. See your
Hardware Owner’s Manual for a system-specific illustration.

Processor Installation 5
Figure 1-2. Removing a Processor
CAUTION: Be careful not to bend any of the pins on the ZIF socket when removing
the processor. Bending the pins can permanently damage the system board.
11 Carefully, lift the processor out of the socket and leave the release lever up
so that the socket is ready for the new processor.
After removing the processor, place it in an antistatic container for reuse,
return, or temporary storage. Do not touch the bottom of the processor.
Touch only the side edges of the processor.
If you are permanently removing the processor, you must install a
processor blank and a heat-sink blank in the CPU2 socket to ensure proper
system cooling. Adding the blank is similar to installing a processor.
See "Installing a Processor".

Installing a Processor
WARNING: Only trained service technicians are authorized to remove the system
cover and access any of the components inside the system. Before you begin this
procedure, review the safety instructions that came with the system.
NOTE: In a single-processor configuration, the CPU1 socket must be used.
1 If you are adding a second processor for the first time, remove the heat-
sink blank and the processor blank from the vacant processor socket.
Removing the blank is similar to removing a processor. See "Removing a
Processor".
2 Remove the processor from the packing material by the processor’s edges
only. Do not touch the bottom of the processor. Handle the processor
carefully with your fingers on the side edges. Place your hand beneath the
processor when you are moving it to the system.
3 Locate the pin 1 indicator on the system board socket.
4 Locate the pin 1 indicator on the top of the processor. The pin 1 indicator
is shown as a triangle on the top of the processor. See Figure 1-4.
CAUTION: Positioning the processor incorrectly can permanently damage
the system board or the processor. Be careful not to bend the pins in the socket.
5 Place the processor over the socket with each pin 1 aligned and level.
See Figure 1-3 and Figure 1-4.
CAUTION: Do not use force to seat the processor. When the processor is
positioned correctly, it engages easily into the socket.
6Align the notches in the p rocessor with the socket keys on t he ZIF
socket. See
Figure 1-4.
7 I nstall the processor in the socket. Keep the processor level
(see Figure 1-3) and insert it straight down into the socket.
Allow the
processor to float on the pins, allowing the processor shield to hold it
in place.

10 R otate the socket-release lever down until it snaps into place.
See Figure 1-5.
Figure 1-5. Installing a Processor
11 Install the heat sink.
NOTE: Your kit may contain a replacement heat sink if you are installing a
processor that consumes additional power. The new heat sink may not appear
different than the original one; however, it has improved thermal dissipation
specifications and must be used.
a
Using a clean lint-free cloth, remove the thermal grease from the heat
sink.
CAUTION: Applying too much thermal grease can result in excess grease coming
in contact with and contaminating the processor socket.

b Open the grease applicator included with your processor kit and apply
all of the thermal grease in the applicator to the center of the topside
of the new processor.
cPlace the heat sink on the processor. See Figure 1-1 .
dClose the heat-sink release levers or replace the screws at the corners
of the heat sink. See your
Hardware Owner’s Manual for a system-
specific illustration. See Figure 1-1.
12 Replace the cooling shroud. See "Installing the Cooling Shroud" in the
Hardware Owner’s Manual .
13 Close the system. See "Closing the System" in the Hardware Owner’s
Manual
.
14 Reconnect your system and peripherals to their electrical outlets, and turn
on the system.
15 Press <F2> to enter the System Setup program, and check that the processor
information
matches the new system configuration. See "Entering the
System Setup Program" in the
Hardware Owner’s Manual .
16 Run the system diagnostics to verify that the new processor operates
correctly.
17 See "Running the System Diagnostics" in the Hardware Owner’s Manual
for information about running the diagnostics.
