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: To guard against electrical shock, always unplug your computer from
the electrical outlet before removing the cover.
WARNING: Do not operate your equipment with any cover(s) (including computer
covers, bezels, filler brackets, front-panel inserts, etc.) removed.
CAUTION: Do not perform the following steps unless you are familiar with
hardware removal and replacement. Performing these steps incorrectly could
damage your system board. For technical service, see the Setup Guide.
CAUTION: Despite having a plastic shield, the heat sink assembly may be very
hot during normal operation. Be sure that it has had sufficient time to cool before
you touch it.
Unpack the new processor, being careful not to touch the underside of
the processor.
CAUTION: You must position the processor correctly in the socket to avoid
permanent damage to the processor and the computer when you turn on the
computer.
If the release lever on the socket is not fully extended, move it to that
position.

For Inspiron 535/537/545, orient the front and rear alignment-notches on
the processor with the front and rear alignment-notches on the socket.
Align the pin-1 corners of the processor and socket.
CAUTION: To avoid damage, ensure that the processor aligns properly with the
socket, and do not use excessive force when you install the processor.
Set the processor lightly in the socket and ensure that the processor is
positioned correctly.
When the processor is fully seated in the socket, close the processor cover,
if applicable.
Ensure that the tab on the processor cover is positioned underneath the center cover latch on the socket.
Pivot the socket release lever back toward the socket, and snap it into place
to secure the processor.
Clean the thermal grease from the bottom of the heat sink.
CAUTION: Ensure that you apply new thermal grease. New thermal grease is
critical for ensuring adequate thermal bonding, which is a requirement for optimal
processor operation.
Apply the new thermal grease to the top of the processor.
