Problem Procedure
eSATA device does 
not work
Remove the eSATA device from the computer 
and then reconnect it to a free port it in order to 
ensure it is firmly attached.
A connected eSATA device may not be 
recognized if it is connected to the computer's 
eSATA/USB combo port while the computer is in 
Sleep Mode or Hibernation Mode. If this occurs, 
disconnect the eSATA device and then reconnect 
the device while the computer is turned on.
Ensure that any required eSATA device drivers 
are properly installed - to achieve this you should 
refer to both the device documentation and the 
operating system documentation.
If you are still unable to resolve the problem, 
contact your reseller, dealer or service provider.
Problem Procedure
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: amber 
twice, then white once.
If there is an error in 
only Slot B: amber 
once, then white twice.
If there are errors in 
both Slot A and Slot B: 
amber twice, then white 
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.
