Point to note about memory module error
If you install a memory module that is not compatible with the computer, the
Power indicator will flashes (on for 0.5 seconds, off for 0.5 seconds) in the
following ways;
■ If there is an error in only Slot A or no memory module is inserted in Slot
A: repeatedly flashes orange twice, then green.
■ If there is an error in Slot B: repeatedly flashes orange, then green
twice.
■ If there are errors in both Slot A and Slot B: repeatedly flashes orange
twice, then green twice.
In all instances you should shut down the computer and remove the
incompatible module(s).
Installing a memory module (Slot A)
To install a memory module, follow the steps as detailed below:
1. Set the computer to Boot Mode and turn its power off - make sure the
Power indicator is off (refer to the Turning off the power section in
Chapter 1, Getting Started if required).
2. Remove the AC adaptor and all cables and peripherals connected to
the computer.
3. Turn the computer upside down and remove the battery pack (refer to
Replacing the battery pack section in Chapter 6, Power and Power-Up
Modes, if required).
4. Turn your computer over.
5. Open the display panel so that the screen faces directly upward.
6. Slip your finger under a notch at the end of the keyboard brace and lift
up to release latches and remove the keyboard brace.
7. Remove two screws securing the keyboard.
Use an adequate screwdriver to remove and fasten the screws - the use of
an incorrect screwdriver can damage the screw heads.
