Memory removal and installation - ThinkPad A30/p, A31/p

These instructions are also available in video format. Click here to go to the removing memory video, or here to go to the installing memory video.

Notes:

  • ThinkPad A30, and A30p use only a PC133 SO-DIMM in your computer. ThinkPad A31, and A31p use only a PC2100 SO-DIMM in your computer. If you install an SO-DIMM that is not supported by your computer, the computer beeps, and the system does not start. You can purchase the appropriate memory accessory from your reseller or marketing representative.
  • 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

To install the SO-DIMM, do the following:

  1. Turn off the computer; then disconnect the ac adapter and all cables from the computer.
  2. Close the computer display, and turn it over.
  3. Remove the battery.
  4. Loosen the screws on the memory slot cover; then remove the cover.

    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.
    use the latches to free the memory
  5. Find the notch on the side of the SO-DIMM you are installing. NOTE: To avoid damaging the SO-DIMM, do not touch its contact edge.
  6. With the notched end of the SO-DIMM toward the side of the socket, insert the SO-DIMM, at an angle of about 20 degrees, into the socket (1); then press it in firmly (2).
    install memory at a 20 degree angle
  7. Pivot the SO-DIMM downward until it snaps into place.
  8. Make sure that the card is firmly fixed in the slot and cannot be moved easily.
  9. Replace the memory slot cover by aligning the back side of the cover first and then tightening the screws. Note: When you have added or upgraded a memory card, do not use your computer until you have closed the memory slot cover. Never use the computer with the cover open.
  10. Put the battery back in place, turn the computer over again, and reconnect the cables.

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

  1. Turn the computer on.
  2. While the Press F1 for BIOS Setup Utility message is displayed at the lower-left area of the screen, press the F1 key. The BIOS Setup Utility screen appears. The Installed memory item shows the total amount of memory installed in your computer. For example, if your computer has 256 MB of memory and you install a 64-MB SO-DIMM in it, the quantity shown in "Installed memory" should be 320 MB.
