Troubleshooting
AC power
If you have trouble turning on the computer with the AC adaptor connected 
you should check the status of the DC IN indicator. Please refer to 
Chapter 6
 for further information.
Battery
If you suspect a problem with the battery, you should check the status of 
the DC IN indicator as well as the Battery indicator. Please refer to 
Chapter 6
 for more information on these 
indicators, together with general battery operation.
It is recommended to leave the computer off until the interior reaches 
room temperature even though the DC IN indicator stops blinking.
If the computer has reached room temperature 
and it still does not start, or if it starts but shuts 
down quickly, contact your reseller, dealer or 
service provider.
Computer shuts down 
and its DC IN indicator 
is flashing white
This indicates a problem with the heat dispersal 
system - you should contact your reseller, dealer 
or service provider.
Problem
Procedure
AC adaptor doesn’t 
power the computer 
(DC IN indicator does 
not glow white)
Check the connections to make sure that the 
power cord/adaptor is firmly connected to the 
computer and a working power outlet.
Check the condition of the cord and terminals. If 
the cord is frayed or damaged it should be 
replaced, while if the terminals are soiled, they 
should be cleaned with a clean cotton cloth.
If the AC adaptor still does not power the 
computer, you should contact your reseller, 
dealer or service provider.
Problem
Procedure
Battery doesn’t power 
the computer 
The battery may be discharged - connect the AC 
adaptor to recharge the battery.
Battery doesn’t charge 
when the AC adaptor is 
attached (Battery 
indicator does not glow 
amber).
If the battery is completely discharged, it will not 
begin charging immediately, in these instances 
you should wait a few minutes before trying 
again. If the battery still does not charge, you 
should check that the power outlet the AC 
adaptor is connected to is supplying power - this 
can be tested by plugging another appliance into 
it.
