Before You Begin

This chapter provides procedures for removing and installing the components in your computer. Unless otherwise noted, each procedure assumes that the following conditions exist:

  • You have performed the steps in “Turning Off Your Computer” and “Before Working Inside Your Computer.”
  • You have read the safety information in your Dell™ Product Information Guide.
  • A component can be replaced or—if purchased separately—installed by performing the removal procedure in reverse order.

Recommended Tools

The procedures in this document may require the following tools:

  • Small flat-blade screwdriver
  • Phillips screwdriver
  • Small plastic scribe
  • Flash BIOS update program floppy or CD

Turning Off Your Computer

NOTICE: To avoid losing data, save and close any open files and exit any open programs before you turn off your computer.
  1. Shut down the operating system:

    1. Save and close any open files, exit any open programs, click the Start button, and then click Turn Off Computer.

    1. In the Turn off computer window, click Turn off.

The computer turns off after the operating system shutdown process finishes.

  1. Ensure that the computer and any attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut down your operating system, press and hold the power button for 4 seconds.

Before Working Inside Your Computer

Use the following safety guidelines to help protect your computer from potential damage and to help ensure your own personal safety.

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a component such as a processor by its edges, not by its pins.
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: When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are correctly oriented and aligned.
NOTICE: To avoid damaging the computer, perform the following steps before you begin working inside the computer.
  1. Ensure that the work surface is flat and clean to prevent the computer cover from being scratched.

  2. Turn off your computer.
  3. If the computer is connected to a docking device (docked), undock it. See the documentation that came with your docking device for instructions.
NOTICE: To disconnect a network cable, first unplug the cable from your computer and then unplug it from the network wall jack.
  1. Disconnect any telephone or network cables from the computer.

  2. 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 you service the computer.
  1. Remove any installed modules, including a second battery, if installed.

  2. Disconnect your computer and all attached devices from their electrical outlets, slide and hold the battery-bay latch release on the bottom of the computer and remove the battery from the bay, and then press the power button to ground the system board.
  3. Remove any installed PC Cards from the PC Card slot.
  4. Remove the hard drive.

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. Install only memory modules that are intended for your computer.

CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.
NOTICE: If your computer has only one memory module, install the memory module in the connector labeled “DIMMA.”
NOTICE: If you remove your original memory modules from the computer during a memory upgrade, keep them separate from any new modules that you may have, even if you purchased the new modules from Dell. If possible, do not pair an original memory module with a new memory module. Otherwise, your computer may not function at optimal performance.
NOTE: Memory modules purchased from Dell are covered under your computer warranty.

Your computer has two user-accessible SODIMM sockets, one accessed from beneath the keyboard (DIMM A), and the other accessed from the bottom of the computer (DIMM B).

To add or replace a memory module in the DIMM A connector:

  1. Follow the procedures in “Before You Begin.”

  2. Remove the keyboard.

NOTICE: To prevent damage to the memory module connector, do not use tools to spread the memory-module securing clips.
  1. If you are replacing a memory module, ground yourself and remove the existing module:

    1. Use your fingertips to carefully spread apart the securing clips on each end of the memory module connector until the module pops up.

    1. Remove the module from the connector.

NOTICE: If you need to install memory modules in two connectors, install a memory module in the connector labeled “DIMMA” before you install a module in the connector labeled “DIMMB.” Insert memory modules at a 45-degree angle to avoid damaging the connector.
  1. Ground yourself and install the new memory module:

NOTE: If the memory module is not installed properly, the computer may not boot properly. No error message indicates this failure.
  1. Align the notch in the module edge connector with the tab in the connector slot.

  1. Slide the module firmly into the slot at a 45-degree angle, and rotate the module down until it clicks into place. If you do not feel the click, remove the module and reinstall it.

To add or replace a memory module in the DIMM B connector:

  1. Follow the procedures in “Before You Begin.”

  2. Turn the computer over, loosen the captive screw in the memory module cover, and then remove the cover.

  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.

To confirm the amount of memory installed in the computer:

  1. Click the Start button, click Help and Support, and then click Computer Information.

Modem

If you ordered the optional modem at the same time that you ordered your computer, the modem is already installed.
