Removing the System Memory (RAM)
The computer has two memory sockets for 200 pin Small Outline Dual In-line Memory Modules (SO-DIMM) supporting
DDR 266/333MHz. The main memory can be expanded up to 2GB. The SO-DIMM modules supported are 128Mb,
256Mb, and 512Mb. The total memory size is automatically detected by the POST routine once you turn on your com-
puter.
Memory Upgrade Process
1. Turn off the computer, remove the battery (page 2 - 5).
2. Locate the RAM bay cover , and remove screws
- (Figure 6a).
3. Remove the bay cover.
4. Gently pull the two release latches ( & ) on the sides of the memory socket in the direction indicated by the
arrows (Figure 6b).
5. The RAM module(s) will pop-up
(Figure 6c), and you can remove it then.
