on the hard disk, and then turn the computer off. Never remove the drive while the system is 
operating or in sleep mode.

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.
To install DDR3 SDRAM, do the following:
1Touch 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.
2Turn off the computer. Disconnect the AC power adapter and all cables from the computer.
3Close the computer display and turn the computer over.
4Remove the main compartment cover.
5Remove the DDR3 SDRAM by pressing out on the latches on both edges of the socket at the 
same time. Be sure to save the old DDR3 SDRAM for future use.
6Align the notch of the DDR3 SDRAM with the protrusion of the socket and gently insert the 
DDR3 SDRAM into the socket at a 30-45° angle.
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.
