You can increase the amount of memory in your computer by installing
double data rate three synchronous dynamic random access memory (DDR3
SDRAM)‐available as an option‐in the memory slot of your computer. DDR3
SDRAM modules are available in various capacities.
To install a DDR3 SDRAM module, 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 DDR3 SDRAM. Do not
touch the contact edge of the DDR3 SDRAM module.
2 Remove the battery pack. For details, see “Replacing the battery pack” on
page 31.
3 Remove the screws , and then remove the bottom slot cover .
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.
• Make sure the computer is turned off and all the cables disconnected from the computer
before you replace the memory.
• Make sure the computer display is closed to avoid being damaged.
