You can install additional memory in the computer’s memory module to

increase the amount of RAM.

Installing memory module

To install a memory module, make sure the computer is in boot mode then:
1. Turn the computer off in boot mode. Refer to the

Turning off the power

section in Chapter 3.

2. Remove all cables connected to the computer.
3. Turn the computer upside down and remove the battery pack

(refer to Chapter 6,

Power and Power-Up Modes

).

4. Remove one screw securing the memory module cover.
5. Lift off the cover.

Only memory modules with the following parts numbers can be installed:
256 MB: PA3389U-1M25

If you use the computer for a long time, the memory modules will

become hot. In this case, let the memory modules cool to room

temperature before you replace them.

Do not try to install a memory module with the computer turned on or

turned off in Standby and Hibernation mode. You can damage the

computer and the memory module.

If you install a memory module that is not compatible with the

computer, a beep will sound when you turn on the power. If the module

is installed in slot A, there will be a long beep followed by a short beep.

If the module is in slot B, there will be a long beep followed by two short

beeps. In this case shut down the power and remove the incompatible

module.

Use a point size 0 Phillips screwdriver.
