❖

Is unlit when the battery has discharged, the battery is not 
charging, or the AC adaptor is not plugged into the 
computer or AC outlet

❖

Flashes amber when the battery charge is low and it is time 
to recharge the battery or plug in the AC adaptor

If the DC-IN light flashes amber during charging, either the battery is 
malfunctioning, or it is not receiving correct input from the AC power 
supply.

Disconnect the AC power cord/cable and remove the battery pack. 
See 

 for information on replacing 

the battery.

Before using the battery to power the computer, you must charge 
the battery.

To charge the battery, leave the computer plugged into an AC power 
source with the computer turned off until the battery light glows 
red. After that, the battery will be completely charged and ready to 
power the computer.

Once the battery is charged for the first time, avoid leaving the 
computer plugged in and turned off for more than a few hours at a 
time. Continuing to charge a fully charged battery can damage the 
battery.

TECHNICAL NOTE: The recharging of the battery cannot occur when 
your computer is using all of the power provided by the AC adaptor 
to run applications, features, and devices. Your computer’s Power 
Options utility can be used to select a power level setting that 
reduces the power required for system operation and will allow the 
battery to recharge.

Battery life and charge time may vary depending on the applications, 
power management settings, and features used.
