Point to note about memory module error

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

Power indicator flashes (on for 0.5 seconds, off for 0.5 seconds) in the

following ways;

■ If there is only an error in Slot A: repeatedly flashes orange twice, then

blue.

■ If there is only an error in Slot B: repeatedly flashes orange, then blue

twice.

■ If there is an error in Slot A and in Slot B: repeatedly flashes orange

twice, then blue twice.

In all instances you should shut down the computer and remove the

incompatible module(s).

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

Modes, if required).
