Removing and Replacing Parts
 
Preparing to Work Inside the
Computer
NOTICE: Only a certified service technician should perform repairs on your
computer. Damage or inoperability due to servicing not authorized by Dell is
not covered by your warranty.
NOTICE: Unless otherwise noted, each procedure in this manual assumes that
a part can be replaced by performing the removal procedure in reverse order.
NOTICE: To avoid damaging the computer, perform the following steps before
you begin working inside the computer.
1 Make sure that the work surface is clean to prevent scratching the
computer cover.
2 Save and close any open files, and exit any open programs.
3 Turn off the computer and all attached devices.
HINT: Make sure the
computer is turned off and
not in standby or
hibernate mode. If you
cannot shut down the
computer using the
computer’s operating
system, press and hold the
power button for 4
seconds.
4 Make sure the computer is undocked.
5 Disconnect the computer from the electrical outlet.
6 To avoid possible damage to the system board, wait 10 to 20 seconds
and then disconnect any attached devices.
7 Disconnect all other external cables from the computer.
8 Remove any installed PC Cards or plastic blanks from the PC Card
slot.
9 Close the display and turn the computer upside down on a flat work
surface.
10 Remove the primary battery from the battery bay and the secondary
battery from the modular bay, if a secondary battery is in use.
NOTICE: To avoid damaging the system board, you must remove the main
battery and secondary battery (if present) before you service the computer.
11 Remove any installed device in the modular bay.
12 To dissipate any static electricity while you work, periodically touch an
unpainted metal surface on the computer, such as the I/O panel on the
back of the computer chassis.

13 Handle components and cards with care. Do not touch the
components or contacts on a card. Hold a card by it edges or by its
metal mounting bracket. Hold a component such as a microprocessor
by its edges, not by its pins.
Recommended Tools
The procedures in this manual require the following tools:
• #1 magnetized Phillips screwdriver
• Small flat-blade screwdriver
• Small plastic scribe
• Microprocessor extractor
• Flash BIOS update program floppy disk or CD (required only when
upgrading the microprocessor, replacing the reserve battery, or
replacing the system board)
Screw Identification
When you are removing and replacing components, photocopy the screw
placemat as a tool to lay out and keep track of the component screws. The
placemat provides the number of screws and the sizes.
NOTICE: When reinstalling a screw, you must use a screw of the correct
diameter and length. Make sure that the screw is properly aligned with its
corresponding hole, and avoid over tightening.
