Power
When the computer is not plugged into an AC outlet, the battery pack is the 
primary power source. However, your computer has a number of other 
power resources, including an intelligent power supply and Real Time Clock 
battery. These resources are interrelated and any one could affect apparent 
power problems. This section provides check lists for AC power and the 
battery. If you cannot resolve a problem after following them, the cause 
could lie with another power resource. In such cases you should contact 
your dealer.
Overheating power down
If the computer’s internal temperature becomes too high, the computer will 
automatically shut down
AC power
If you have trouble turning on the computer with the AC adapter connected, 
check the DC IN indicator. Refer to Chapter 6, Power and Power-Up Modes, 
for more information.
Problem Procedure
AC adapter doesnt 
power the computer 
(DC IN indicator does 
not glow blue).Check the connections. Make sure the cord is 
firmly connected to the computer and a power 
outlet.
Check the condition of the cord and terminals. If 
the cord is frayed or damaged, replace it. If the 
terminals are soiled, wipe them with cotton or a 
clean cloth.
If the AC adapter still does not power the 
computer, contact your dealer.

Battery
If you suspect a problem with the battery, check the DC IN indicator as well 
as the indicators for the battery. For information on indicators and battery 
operation see Chapter 6, Power and Power-Up Modes.
Problem Procedure
Battery doesnt power 
the computer.The battery may be discharged. Connect the AC 
power cord to charge the battery.
Battery doesnt charge 
when the AC power 
cord is attached. 
(Battery indicator does 
not glow amber.)If the battery is completely discharged, it will not 
begin charging at once. Wait a few minutes.
If the battery still does not charge, make sure the 
outlet is supplying power. Plug in an appliance 
and see if it works. If it doesnt, try another power 
source.
Check whether the battery is hot or cold. If the 
battery is too hot or too cold, it will not charge 
properly. Let it reach room temperature. 
Unplug the AC adapter and remove the battery to 
make sure the terminals are clean. If necessary 
wipe them with a soft dry cloth dipped in alcohol.
Connect the AC adapter and replace the battery.
Check the Battery indicator. If it does not glow, 
let the computer charge the battery for at least 20 
minutes. If the Battery indicator glows after 20 
minutes, let the battery continue to charge for at 
least another 20 minutes before turning on the 
computer.
If the indicator still does not glow, the battery may 
be at the end of its operating life. 
Replace it.
If you do not think the battery is at the end of its 
operating life, see your dealer.
Battery doesnt power 
the computer as long as 
expected.Check the power consumption settings in the 
Power Options. Consider using a power saving 
mode.
