You can increase the amount of memory in your computer by installing a 
double-data-rate three synchronous dynamic random access memory (DDR3 
SDRAM)-available as an option-in the memory slot of your computer. DDR3 
SDRAMs are available in various capacities.

 To install a DDR3 SDRAM, do the following: 
1 Touch a metal table or a grounded metal object to reduce any static elec-

tricity in your body, which could damage the DDR3 SDRAM. Do not 
touch the contact edge of the DDR3 SDRAM. 

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 again.
5 Remove the Optical drive/Hard disk drive (HDD)/Memory/CPU (Cen-

tral processing unit)/Mini PCI Express Card slot compartment 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.

• Select models of the computer may have only one memory slot. Refer to the actual product. 

However, the procedure for replacing the memory is the same as listed below.
