Please also refer to Chapter 3, 

, for further 

information on installing and removing memory modules.

If there is a memory 
malfunction, the 
Power indicator will 
repeatedly flash (on 
for 0.5 seconds, off 
for 0.5 seconds) in 
the following patterns;

If there is an error in 
only slot A: orange 
twice, then green 
once.

If there is an error in 
Slot B: orange once, 
then green twice.

If there are errors in 
both Slot A and Slot 
B: orange twice, then 
green twice.

In the event the Power indicator flashes when 
the computer is turned on, you should first check 
that the installed memory module(s) are 
compatible with the computer. If there is an error 
with a compatible memory module, there is a 
possibility the memory module is damaged.

If you determine that an incompatible module has 
been installed, you should follow the steps as 
detailed below:

1. Turn off the computer.

2. Disconnect the AC adaptor and all peripheral 

devices.

3. Remove the battery pack.

4. Remove the incompatible memory module.

5. Install the battery and/or connect the AC 

adaptor.

6. Turn on the computer.

If you are still unable to resolve the problem, 
contact your reseller, dealer or service provider.

An error will occur if a 
memory module is 
inserted into Slot B 
while no memory 
module is inserted in 
Slot A.

Remove the memory module from Slot B and 
insert it into Slot A.
