You can increase the amount of memory in your computer by installing a
double-data-rate three low voltage synchronous dynamic random access
memory (DDR3L SDRAM)-available as an option-in the memory slot of your
computer. DDR3L SDRAMs are available in various capacities.

To install a DDR3L SDRAM, 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 DDR3L SDRAM. Do
not touch the contact edge of the DDR3L SDRAM.

2 Turn off the computer. Disconnect the AC power 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/Memory/Central 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.
