Dell™ Inspiron™ 8000: 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.
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 media 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 media bay.
12 To dissipate any static electricity while you work, periodically touch an
unpainted metal surface on the surface of 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
• Number 1 magnetized Phillips screwdriver
• Small flat-blade screwdriver
• Pry stick
• 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).
NOTICE: If the computer is running Microsoft® Windows® Millennium
Edition (Me), you need to download the operating system update utility for
Windows Me from http://support.dell.com and install it before you upgrade the
BIOS.
Screw Identification
Before removing and replacing components, photocopy the screw placemat
as a tool to lay out and keep track of the screws. The placemat provides the
number of screws and the sizes.
74 Dell™ Inspiron™ 8000: Removing and Replacing Parts
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.

1
If you only have one memory module, install it in the connector
labeled "DIMM A." If you have two memory modules, install the
second module in the connector labeled "DIMM B."
2 Insert the memory module’s edge connector with the slot at a 45-
degree angle, and press the memory module firmly into the slot.
3 Pivot the memory module down until it clicks into place. If you do not
hear a click, remove the module and reinstall it.
