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.
Important:
Read Chapter 7. “Safety, use, and care information” before replacing
memory.
