Replacing memory

You can increase the amount of memory in your computer by installing a double data rate
(DDR 3) 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 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 to reduce any static electricity in your body,
which could damage the SO-DIMM. Do not touch the contact edge of the SO-DIMM.
2
Turn off the computer. Disconnect the AC adapter and all cables from the computer.
3
Close the computer display, and turn the computer over.
4
Remove the battery pack.
5
Remove the Memory/Wireless module/CPU (central processing unit) compartment cover.
a. Remove the screws that secure the compartment cover
b. Remove the compartment cover
