Adding Memory

You can increase your computer memory by installing memory modules on the system board. See "Specifications" for information on the memory supported by your computer. Be sure to add only memory modules that are intended for your computer.

NOTE: Your computer is optimized for the use of the 266-MHz DDR DDRAM memory modules sold by Dell. When adding memory, ensure that you purchase the same type of memory from Dell.
NOTE: Memory modules purchased from Dell are covered under your computer warranty.
CAUTION: Before working inside your computer, read "Safety and EMC Instructions: Mobile Workstation Computers" in your System Information Guide.
  1. Save and close any open files, exit any open programs, and shut down the computer.

  2. If the computer is docked, undock it.

  3. Remove any installed PC Cards.

  4. Remove all installed batteries, and disconnect the AC adapter cable and any external devices from the computer. Wait 5 seconds before proceeding.

  5. Ground yourself by touching a metal connector on the back of the computer, and continue to do so periodically during this procedure.

NOTICE: While you work, periodically touch unpainted metal on the computer to dissipate static electricity that might harm internal components.
  1. Turn the computer over, remove the screw(s) from the memory module cover, and lift up the cover.

NOTICE: To prevent damage to the memory module connector, do not use tools to spread the inner metal tabs that secure the memory module.
  1. If you are replacing a memory module, remove the existing module.

NOTICE: Handle memory modules by their edges, and do not touch the components on a module.
    1. Use your fingertips to carefully spread apart the securing clips on each end of the memory module connector.

The module should pop up.

    1. Remove the module from the connector.

NOTE: There are no configuration restrictions regarding which of the memory sockets you use or the order of the memory modules.
  1. Ground yourself and install the new memory module:

    1. Align the notch in the module with the slot in the center of the connector.

    1. Slide the edge of the module firmly into the connector, and rotate the module down until you hear a click. If you do not hear the click, remove the module and reinstall it.

  1. Replace the cover and screw(s).

NOTICE: If the memory module cover is difficult to close, remove the module and reinstall it. Forcing the cover to close may damage your computer.
  1. Insert the battery into the battery bay, or connect the AC adapter to your computer and an electrical outlet.

  2. Turn on the computer.

As the computer boots, it detects the additional memory and automatically updates the system configuration information. If the memory module is not installed properly, the computer does not boot; no error message appears to indicate this failure.


Adding a Mini PCI Card

If you ordered a Mini PCI card at the same time that you ordered your computer, Dell has already installed the card for you.

NOTE: Handle components and cards by their edges, and avoid touching pins and contacts.
CAUTION: Before working inside your computer, read "Safety and EMC Instructions: Mobile Workstation Computers" in your System Information Guide.
  1. Make sure that the work surface is flat and clean to prevent scratching the computer cover.

  2. Save and close any open files, exit any open programs, and shut down the computer.

  3. If the computer is docked, undock it.

  4. Disconnect the computer from the electrical outlet.

  5. Wait 10 to 20 seconds and then disconnect any attached devices.

  6. Remove any installed PC Cards, batteries, and devices.

  7. Ground yourself by touching a metal connector on the back of the computer, and continue to do so periodically during this procedure.

  8. Turn the computer over, and remove the screw from the Mini PCI card cover.

  9. Place your finger under the cover at the indentation, and lift and slide the cover open.

  1. If you are replacing a Mini PCI card, remove the existing card:

    1. Disconnect the assembly from the wiring harness or internal antenna.

    1. Release the Mini PCI card by spreading the metal securing tabs until the card pops up slightly.

    2. Lift the Mini PCI card out of its connector.

  2. To install the Mini PCI card, align it with the connector at a 45-degree angle, press it into the connector, and pivot it down until it snaps into the metal securing tabs.

  3. Connect the antenna cable to the antenna cable connector on the Mini PCI card. Route the cable under the corner of the card to prevent interference when replacing the Mini PCI card cover.

NOTICE: The connectors are keyed for correct insertion; do not force the connections.

Replacing the Hard Drive

NOTICE: To prevent data loss, turn off your computer before removing the hard drive. Do not remove the hard drive while the computer is on, in standby mode, or in hibernate mode.
NOTICE: Hard drives are extremely fragile; even a slight bump can damage the drive.
CAUTION: If you remove the hard drive from the computer when the drive is hot, do not touch the metal housing of the hard drive.
CAUTION: Before working inside your computer, read "Safety and EMC Instructions: Mobile Workstation Computers" in your System Information Guide.
NOTE: Dell does not guarantee compatibility or provide support for hard drives from sources other than Dell.

To replace the hard drive in the hard drive bay:

  1. Make sure that the work surface is flat and clean to prevent scratching the computer cover.

  2. Save and close any open files, exit any open programs, and shut down the computer.

  3. If the computer is docked, undock it.

  4. Disconnect the computer from the electrical outlet.

  5. Wait 10 to 20 seconds and then disconnect any attached devices.

  6. Remove any installed PC Cards, batteries, and devices.

Handle components and cards by their edges, and avoid touching pins and contacts.

  1. Ground yourself by touching a metal connector on the back of the computer, and continue to do so periodically during this procedure.

  2. Turn the computer over. Use a small screwdriver to remove the hard drive screw(s), and place the screw(s) in a safe location.

NOTICE: When the hard drive is not in the computer, store it in protective antistatic packaging. See "Protecting Against Electrostatic Discharge" in your System Information Guide."
  1. Lift the hard drive cover until you hear a click.

  2. Slide the hard drive out of the computer.

  3. Remove the new drive from its packaging.

Save the original packaging to use when storing or shipping the hard drive.

NOTICE: Use firm and even pressure to slide the drive into place. If you force the hard drive into place using excessive force, you may damage the connector.
  1. Insert the drive into the bay, and lift the hard drive cover until you hear a click. Push the hard drive until it is fully seated in the bay. Press the hard drive cover down.

  2. Replace and tighten the hard drive screw(s).

  3. Use the Operating System CD to install the operating system for your computer.

  4. Use the Drivers and Utilities CD to install the drivers and utilities for your computer.


Connecting a TV to the Computer

Your computer has an S-video TV-out connector that, together with the included TV/digital audio adapter cable, enables you to connect the computer to a television and/or stereo audio device. The TV/digital audio adapter cable provides connections for S-video, composite video, and S/PDIF digital audio.
