Replacing memory
Important:
Read Chapter 7. "Safety, use, and care information" before replacing
memory.
Increasing memory capacity is an effective way to make programs run
faster. You can increase the amount of memory in your computer by
installing a double data rate (DDR) 2 synchronous dynamic random access
memory (DRAM) unbuffered small outline dual inline memory module
(SO-DIMM), available as an option, in the memory slot of your computer.
SO-DIMMs with different capacities are available.
Note:
Use only the memory types supported by your computer. If you incorrectly
install the optional memory or install an unsupported memory type, a
warning beep will sound when you try to start the computer.
To install an SO-DIMM, do the following:
1
Touch a metal table or a grounded metal object. This action reduces
any static electricity in your body, which could damage the SO-DIMM.
Do not touch the contact edge of the SO-DIMM.
2
Turn off the computer; then disconnect the AC adapter and all cables
from the computer.
3
Close the computer display, and turn the computer over.
