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 33.
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.
•
Two memory channels are supported. Both channels should have a memory of the same
size and rank. You should install the ram in Slot 1 if there is only ONE ram module.
