Increasing memory capacity is an effective way to make programs run faster. You can increase the amount of memory in your system by installing PC2-4200 CL4 Non-Parity Double Data Rate Two (DDR2) Synchronous Dynamic Random Access Memory (SDRAM) Small Outline Dual Inline Memory Module (SO-DIMM), available as an option, in the memory slot on the bottom of the system. SO-DIMMs with different capacities are available.

Note:
  • Use only PC2-4200 Non-Parity DDR2 SDRAM SO-DIMM in your system.
  • If you install a SO-DIMM that is not supported by your system, the system beeps, and the system does not start.
  • You can purchase the appropriate memory option from reseller or marketing representative.

To install a SO-DIMM, do the following:

Attention: Before you start installing a module, touch a metal table or a grounded metal object. This action reduces any static electricity from your body. The static electricity could damage the SO-DIMM. Be careful to avoid the metallic projections in the SO-DIMM socket area.

  1. Turn off the system; then disconnect the ac adapter and all cables from the system.
  2. Close the system display, and turn it over.
  3. Remove the battery.
  4. Remove the palm rest.
  5. If the SO-DIMM is already in the memory slot, remove it to make room for the new one by pressing out on the latches on both edges of the socket at the same time. Be sure to save it for future use.
    To remove the DIMM, press out on the latches on both edges of the socket.

  6. Find the notch on the contact edge side of the SO-DIMM.

    Attention: To avoid damaging the SO-DIMM, do not touch its contact edge.

  7. With the notched end of the SO-DIMM toward the contact edge side of the socket, insert the SO-DIMM into the socket at an angle of about 20 degrees (1); then press it firmly (2).
    Insert the DIMM into the socket at an angle of about 20 degrees; then press it firmly.

  8. Pivot the SO-DIMM downward until it snaps into place.
  9. Make sure that the card is firmly fixed in the slot and does not move easily.
  10. Replace the memory slot cover by aligning the back side of the cover first and then tightening the screw.
    Note: When you have added or upgraded an SO-DIMM, do not use your system until you have replaced the palm rest. Never use the system with the palm rest off.
  11. Replace the palm rest.
  12. Reinstall the battery.
  13. Turn the system over again, and reconnect the cables.

To make sure that the SO-DIMM is installed correctly, do as follows:

  1. Turn the system on.
  2. While the "To interrupt normal startup, press the ThinkVantage button" message is displayed at the lower-left of the screen, press the ThinkVantage button. The ThinkVantage Rescue and Recovery screen opens.
  3. Click Access BIOS. The System Restart Required window is displayed.
  4. Click Yes. The system restarts, and the BIOS Setup Utility screen opens. The "Installed memory" item shows the total amount of memory installed in your system.
    For example, if your system has 256 MB of memory and you install a 256-MB SO-DIMM in it, the quantity shown in "Installed memory" should be 512 MB.
