134 Installing System Components
Removing a Processor
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.
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 three 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" on page 84.
4 Remove the cooling shroud. See "Removing the Cooling Shroud" on
page 96.
WARNING: The heat sink and processor are hot to 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. See Figure 3-23.
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 the processor and keep it aside upside down
(thermal grease side facing up).
