Operating with Battery Power
Replacing the Battery
CAUTION
Before removing the battery pack, make sure that
you have an AC adapter connected to the device or a media
bay battery installed; otherwise, first turn off the device.
To Remove the Battery:
1.
Plug in AC power or turn off the device.
2.
Turn over the notebook so you are looking at the bottom.
3.
Press and hold down the battery lock in the hinge to unlock
the battery.
4.
Slide the battery release latches toward the inside of the
device to release the battery.
5.

Battery Release Latches
To Install the Battery:
1.
Turn the notebook over so you are looking at the bottom.
2.
Align the battery connector.
3.
Press gently on the battery until it clicks into place.
NOTE
When using a battery pack for the first time, it is
recommended that you calibrate the battery so the gas gauge
accurately displays battery capacity.
Battery Charging
To charge the battery, install the battery pack and plug the
AC adapter into the device and an electrical outlet. You can
use your device while charging the battery. However, this will
increase the charging time.
While the battery is charging, the
Battery Power LED
will
be active after 6-12 seconds and stay lit until the battery is
fully charged. When the battery is fully charged, the LED turns
off.
If your device is off or suspended, a fully discharged battery
takes about 4 hours to recharge. If your device is turned on it
may take four to six (4- 6) hours to recharge the battery.

NOTE
A fully charged battery can power the device for
approximately eight (8) hours, depending on usage patterns.
If your device also has the optional Media Bay battery, it will
power the device for an additional four (4) hours.
When to Replace the Battery
Over time, the battery’s capacity gradually decreases. We
recommend that you replace your battery if it no longer
provides 70% of its original rated capacity.
WARNING
Only use approved batteries when replacing the
battery.
Heat Considerations
The device’s processor has been specially designed to
consume as little power as possible. However, working in a
hot environment, or working for long periods may raise the
temperature. Your device takes the following steps to lower
temperature:
The cooling fan turns on. You may hear the fan and feel air
coming from a vent on the left side of the device when this
happens.
If the temperature continues to rise, processor activity is
reduced. You may notice a slight loss of performance if this
happens.
To prevent damage, if the device gets too hot, the
processor stops and the device shuts down.
