Appendix A. CRU instructions

Replacing memory --------------------------------------------------------------------------

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.

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.

To install a DDR3 SDRAM, do the following:

1Touch 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.

2Turn off the computer. Disconnect the AC adapter and all cables from the computer.

3Close 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.
