Before You Begin
Preparing to Work Inside the Computer
CAUTION: Before you perform any of the procedures in this section, follow the safety instructions in the
Product Information Guide
NOTICE: 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.
NOTICE: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically
touching an unpainted metal surface (such as the back panel) on the computer.
NOTICE: Handle components and cards with care. Do not touch the components or contacts on a card.
Instead, 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 disconnecting a cable, pull on the cable’s connector or on its strain-relief loop, not on the
cable itself. Some cables have connectors with locking tabs; before disconnecting this type of cable, press
inward on the locking tabs to release the connector. When connecting or disconnecting a cable, ensure that
the connectors are correctly oriented and aligned to avoid damage to the connector and/or the connector’s
pins.
NOTICE: To avoid damaging the computer, always 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.
.
1
NOTE: Ensure that the computer is off and not in a power management mode. If you cannot shut down
the computer using the operating system, press and hold the power button for 4 seconds.
4
Disconnect the computer from the electrical outlet.
NOTICE: To avoid damaging the system board, wait 10 to 20 seconds before disconnecting any attached
devices.
5
Disconnect all attached devices.
6
Disconnect all external cables from the computer.
7
Close the display and turn the computer upside down on a flat work surface.
NOTICE: To avoid damaging the system board, you must remove the main battery before servicing the
computer.

About the Device Security Screw
NOTE: You do not need to install the device security screw unless you want to prevent the optical drive from
being easily removed.
Your Dell™ computer ships with a CD/DVD drive installed in the optical drive bay along with an M2.5
x 8-mm device security screw. If the security screw is not already installed, it will be packaged separately.
When you insert a drive into the bay, you can install the device security screw to prevent the drive from
being easily removed.
Removing the Optical Drive
CAUTION: Before you perform any of the procedures in this section, follow the safety instructions in the
Product Information Guide
NOTICE: To prevent damage to optical drives and other devices, store them in a safe, dry place when they are
not installed in the computer. Avoid pressing down on them or placing heavy objects on top of them.

Memory Module and Modem
Your Dell computer comes equipped with two memory slots/connectors labeled DIMM A and
DIMM B. DIMM A (located under the keyboard) holds the primary memory module as configured
from the factory. DIMM B (located on the bottom of the computer) holds any additional memory
you may have ordered. If you did not order additional memory, DIMM B will be empty.
Generally, if you are adding memory, you will install a memory module in DIMM B only. If you are
upgrading the memory, you may need to install memory modules in DIMM A and DIMM B,
depending on the extent of the upgrade.
NOTE: Memory modules purchased from Dell™ are covered under your computer warranty.

Follow the instructions in "Removing the Microprocessor Module" on page 75.
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. A microprocessor module that is not
properly seated can result in an intermittent connection or permanent damage to the microprocessor and ZIF
socket.

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.
NOTE: Gently press down on the substrate on which the processor die is mounted to ensure the
microprocessor module is properly seated.
When the microprocessor module is properly seated, all four corners of the module are aligned at the
same height. If one or more corners of the module is higher than the others, the module is not properly
seated.
