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. |
- Make sure that the work surface is clean to
prevent scratching the computer cover.
- Save and close any open files, and exit any
open programs.
|
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. |
- Turn off the computer and all attached
devices.
- Make sure the computer is undocked.
- Disconnect the computer from the electrical
outlet.
- To avoid possible damage to the system board,
wait 10 to 20 seconds and then disconnect any attached devices.
- Disconnect all other external cables from the
computer.
- Remove any installed PC Cards or plastic
blanks from the PC Card slot.
- Close the display and turn the computer upside
down on a flat work surface.
- 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. |
- Remove any installed device in the modular
bay.
- 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.
- 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.
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)
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. |

module with the pin-1 corner of the microprocessor socket on the system board
and insert the microprocessor module.
|
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 to the same height. If one or more corners of the module are
higher than the others, the module is not seated correctly.
|
