When installing: Insert the notched end of the DIMM into the socket. Press the DIMM firmly, and pivot it until it
snaps into the place. Make sure that it is firmly fixed in the slot and does not move easily.
Note: If only one DIMM is used on the computer you are servicing, the card must be installed in the lower slot of the
slots under the keyboard. See “1120 DIMM slot cover and DIMM under keyboard for W701 and W701ds” on page 86.

converter” on page 70
Note:
In models with the fingerprint reader, the sensor is attached to the palm rest FRU. If the fingerprint reader
has any defects, you can replace it by the procedures given in this section, which are the same for a palm
rest with or without a fingerprint reader.
