The main battery light ( ) glows amber while the battery is
being charged, and glows blue when it is fully charged.
The battery may not start charging immediately under the
following conditions:
❖The battery is extremely hot or cold. To ensure that the
battery charges to its full capacity, wait until it reaches
room temperature.

power connected and the battery should begin charging
after a few minutes.
Maximizing battery life
To maximize the life of your battery pack:
❖At least once a month, disconnect the computer from a
power source and operate it on battery power until the
battery pack fully discharges. Before doing so, follow the
steps below:
1Turn off the computer’s power.
2Disconnect the AC adapter and turn on the
computer’s power. If it does not turn on, go to step 4.
3Operate the computer on battery power for five
minutes. If the battery pack has at least five minutes
of operating time, continue operating until the battery
pack is fully discharged. If the battery light LED
flashes or there is some other warning to indicate a
low battery, go to step 4.
4Connect the AC adapter to the computer and the
power cord to a power outlet. The DC-IN or AC
power-light LED should glow blue, and the Battery
LED should glow amber to indicate that the battery
pack is being charged. If the DC-IN or AC power-
light indicator does not glow, power is not being
supplied. Check the connections for the AC adapter
and power cord.
