Replacing memory (Select models only) - - - - - - - - - - - - - - - - - - - - -
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 Hard disk drive (HDD)/Memory/CPU (Central processing
unit)/Mini PCI Express Card slot compartment cover.
a.Loosen the five screws .
b.Remove the 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.
