Replacing memory

(DRAM) unbuffered small outline dual inline memory module (SO-DIMM), available as an option, in the memory slot of your computer. SO-DIMMs with different capacities are available.

Note: Use only the memory types supported by your computer. If you incorrectly install the optional memory or install an unsupported memory type, a warning beep will sound when you try to start the computer.

To install an SO-DIMM, do the following:

1.Touch a metal table or a grounded metal object. This action reduces any static electricity in your body, that could damage the SO-DIMM. Do not touch the contact edge of the SO-DIMM.

2.Turn off the computer; then disconnect the ac adapter and all cables from the computer.

3.Close the computer display, and turn the computer over.

4.Remove the battery.

5.Remove the screws that hold the palm rest in place.
