Taking care of your battery

The following sections offer tips on how to take care of your battery
and prolong its life.
Maintaining your battery
Fully discharging your battery will allow better accuracy of the
battery meter.
To fully discharge your battery:
❖ Periodically, disconnect the computer from a power source and
operate it on battery power until the battery fully discharges.
Before doing so, follow the steps below:
1
2
3
4
5
❖ If you are not going to use the computer for more than eight
hours, disconnect the AC adaptor.
The computer battery is not accessible by the user.
TECHNICAL NOTE: To avoid losing any data, save your files and
then either completely shut down your computer or put it into
Hibernation mode before changing the main battery.
Turn off the computer's power.
Disconnect the AC adaptor and turn on the computer's
power. If it does not turn on, go to step 4.
Operate the computer on battery power for five minutes. If
the battery has at least five minutes of operating time,
continue operating until the battery is fully discharged. If
the battery light flashes or there is some other warning to
indicate a low battery, go to step 4.
Connect the AC adaptor to the computer and the
power cord/cable to a power outlet. The DC-IN or AC
power-light should glow green, and the battery light
should glow amber to indicate that the battery 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 adaptor and power cord/cable.
Charge the battery until the battery light glows green.
