Preparing to Work Inside the 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. Read and follow the safety instructions in the Owner's Manual that
came with the computer.
CAUTION: To prevent static damage to components inside your computer, discharge
static electricity from your body before you touch any of your computer's electronic
components. You can do so by touching an unpainted metal surface.
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 microprocessor by its edges, not by its pins.
NOTICE: When you disconnect a cable, pull on its connector or on its strain-relief loop, not on
the cable itself. Some cables have a connector 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.
NOTICE: 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 scratching the computer cover.
2. Save any work in progress and exit all open programs.
3. Turn off the computer and all attached devices.

Microprocessor Module: Dell Inspiron XPS and Inspiron 9100 Service Manual
NOTICE: Ensure that the cam lock is in the fully open position before seating the
microprocessor module. Seating the microprocessor module properly in the ZIF socket does not
require force.
NOTICE: A microprocessor module that is not properly seated can result in an intermittent
connection or permanent damage to the microprocessor and ZIF socket.
1. Align the pin-1 corner of the microprocessor module with the pin-1 corner of the ZIF socket,
and insert the microprocessor module.
NOTE: The pin-1 corner of the microprocessor module has a triangle that aligns with the
triangle on the pin-1 corner of the ZIF socket.
NOTICE: You must position the microprocessor module correctly in the ZIF socket to avoid
permanent damage to the module and the socket.
When the microprocessor module is correctly seated, all four corners are aligned at the same
height. If one or more corners of the module are higher than the others, the module is not seated
correctly.
2. Tighten the ZIF socket by turning the cam screw clockwise to secure the microprocessor module
to the system board.
3. Perform the steps in "Removing the Microprocessor Module" in reverse order, beginning with
step 7.
