Appendix A. CRU instructions Replacing memory 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 is available in various capacities. Notes: • 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. To install DDR3 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 DDR3 SDRAM. Do not touch the contact edge of the DDR3 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 pack. 5 Remove the Optical drive/Hard disk drive/Memory/Central processing unit/Mini PCI Express Card slot compartment cover. 36
