The instructions below describe how to add a memory module to the Toshiba portable computers listed above.

If you are not a technically advanced user, or if you have any concerns about partially disassembling your computer, Toshiba recommends arranging for memory module installation with an Authorized Service Provider (ASP). To locate an ASP anywhere in the world, visit Toshiba's Global ASP Locator at http://pcrepair.toshiba.com.

Toshiba will not be responsible for any product damage, data loss, service, or part replacement made necessary by installation of a memory module. These computers have two SODIMM memory slots, located under the keyboard. One or both of the slots is populated with memory modules during the manufacturing process. If one of the memory slots is empty, then you may increase the total memory capacity of the computer by adding the capacity of a new memory module to the capacity of the existing module. For example, if the computer currently has 512 MB of memory, adding a second 512 MB module would increase the total memory capacity of the computer to 1 GB.

If both slots are already populated, increasing the computer's memory capacity involves replacing one or both of the existing modules with larger capacity modules. For example, if the computer currently has two 256 MB modules - for a total memory capacity of 512 MB - then replacing one of them with a 512 MB module would increase the computer's total memory capacity to 768 MB, and replacing both of them with 512 MB modules would increase the total memory capacity to 1 GB.

Tools required: a small Phillips screwdriver.

1. Click Start, and then Turn off computer or Shut Down (depending on your computer model).

The Turn off computer or Shut Down window appears.

2. Click Shut Down or Turn Off. The operating system turns off the computer.

3. Unplug and remove any cables connected to the computer, including the AC adaptor.

4. Remove the battery from the computer.

5. Fold the LCD panel all or most of the way toward the back of the computer.

6. Remove the keyboard holder by inserting fingertips into both cutouts, as in the illustration below, and then pulling the top edge of the keyboard holder toward you, to release it from the computer's chassis.

7. Using a small Phillips screwdriver, remove the two screws holding the keyboard in place.

Note: The memory cover screws and the keyboard screws are not interchangeable. Be sure to keep them separated.

8. Press the spring latch toward the back of the computer to release the keyboard.

9. Raise the top edge of the keyboard up about an inch, then slide the keyboard toward the LCD panel about half an inch, so that the two tabs at the bottom edge of the keyboard clear the palmrest.

10. Fold the keyboard over so that it rests upside-down on top of the palmrest, as shown below.

11. Using a small Phillips screwdriver, unscrew the screws that secure the memory slot cover . Place the screws and the cover in a safe place so that you can retrieve them later.

Note: Keep the memory slot cover screws separated from the keyboard screws, which are different.

The two memory module slots are now accessible (one or both slots may be populated with memory modules).

CAUTION! If the computer has been running recently, the memory module may be hot . The surrounding area may also be hot. Allow the module to cool to room temperature before replacing it. Avoid touching the cover, the module, and the surrounding area before they have cooled. Failure to follow these directions could result in minor bodily injury.

CAUTION: Static electricity can damage electronic circuits, including memory modules. Before handling your memory module, touch a grounded metal surface to discharge any static electricity you may have accumulated.

CAUTION: Avoid touching the connectors (electrical contacts) on the memory module, or in the computer. Oil from your fingertips, grease, or dust may cause an imperfect connection, which can cause memory access problems. Pick up and hold the module by its side edges.

If one of the slots is empty, skip the module removal instructions immediately below, and proceed to step 15 to install a memory module.

If both slots are already populated, it will be necessary to remove and replace one of the modules in order to increase the total memory capacity. Remove one module per the steps immediately below, and then continue to step 15.

12. Pull the latches away from the memory module. The memory module pops up slightly.

13. Grasping the module at its side edges, gently lift the memory module to a 30-degree angle and slide it out of the slot.

14. Place the module into an anti-static bag or container, if possible.

15. Carefully remove the new memory module from its antistatic packaging, without touching its connector.

16. Pick up the memory module by its sides, avoiding any contact with its connector. Position the module toward the socket, aligning the connector’s notch with the matching key in the socket.

17. Firmly press the memory module into the memory slot's socket, at approximately a 30 degree angle (to the horizontal surface of the computer).

18. Once the module’s connector is fully inserted into the socket, press downward on the top edge of the module to seat the module into the latches at the sides of the socket. These latches should "snap" into place securely with the corresponding cutouts in the side of the module.

If the latches and cutouts do not line up correctly, repeat steps 12 and 13 above, and then steps 16-18.

Do not force the memory module into position. The memory module should be completely inserted into the socket and level when secured in place.

The installation of the memory module is now complete.

19. Replace the memory module slot cover and secure it using the screws.

20. Fold the keyboard back into position and insert the tabs at the bottom of the keyboard back under the palmrest. Then gently press the top down to re-engage the latch and replace the two screws that secure the keyboard to the computer.

21. Snap the keyboard holder back in place, making sure that each tab engages with the computer's chassis.

22. Re-insert the main battery and reconnect the cables.

Verify that the computer recognizes the new memory module, as follows:

23. Press the computer's power button, and then immediately press and hold the Esc key (at the upper left of the keyboard).

24. Press the F1 key at the corresponding prompt. The computer's total memory capacity will be displayed at the upper left of the BIOS Setup screen.

25. Press the Esc key again, and then the Y key at the following prompt. The computer will then start Windows.

The computer is now ready for use, with its newly-expanded memory capacity.
