Replacing memory ------------------------------------------------------------------

You can increase the amount of memory in your computer by installing a double data rate (DDR3) small outline dual inline memory module (SO- DIMM)-available as an option-in the memory slot of your computer. SO- DIMMs are available in various capacities.

Note: Use only the memory types supported by your computer. If you incorrectly install 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:

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

2Turn off the computer. Disconnect the AC adapter and all cables from the computer.

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

4Remove the battery again.
