N211U NOTEBOOK USER’S MANUAL
2.1 Using the Battery Pack
N211U notebook computer is designed to operate with one ofthe
following power sources:
• AC power
(using the AC adapter connected to an electrical outlet)
• Lithium-Ion (Li-Ion) battery pack
You should use the AC adapter whenever it is possible, relying on
the battery pack only when AC power is unavailable. The recharge
-
able Li-Ion battery pack allows you to operate notebook computer
without an external power source.When you use the AC adapter to
connect your Notebook to a power outlet, the internal battery will
automatically begin to recharge. While the battery is charging, the
Battery Charge icon on the Indicator panel will be active. When the
battery is fully charged, the Battery Charge icon will turn off. If your
computer is turned off or standby mode, a fully discharged battery
will take about 3 hours to recharge.
• Operating a fax modem, video, or audio equipment increases the
computer’s power requirements.
• Decreasing monitor brightness can also save power.
The battery is not fully charged. Allow your battery to fully charge
before using it (i.e., before disconnecting AC power). Calibrating
the battery before use is also highly recommended.
• Li-Ion Battery is vulnerable, do not charge it with other power
adapter, or it may cause fire or explosion.
►Replacing the Battery◄
Over time, the battery’s capacity gradually decreases. We recom
-
mend that you replace your battery when you notice that it begins
to store significantly less charge.
To replace the battery, please follow the steps as below:
1. Turn off the computer.
2. Close the screen cover and turn the computer over.
3. Slide the side battery latch (1) to the left. Continue to hold it until
the battery is removed.
4. Make sure the replacement battery is properly oriented. Insert
the battery into the battery compartment.
►Maintenance of the AC Adapter◄
• Do not connect the adapter to any other device.
• Do not step on the power cord or place heavy objects on top of it.
Carefully route the power cord and any cables away from all po-
tential traffic.
• When unplugging the power cord, do not pull on the cord itself but
pull on the plug.
• The total ampere rating of the equipment plugged in should not
exceed the ampere rating of the cord if you are using an exten
-
sion cord. The total rating of all equipment plugged into a single
wall outlet should not exceed the fuse rating.
• Make sure the voltage of the power source before connecting
your notebook computer to the power outlet. If you are uncertain
of your power specifi cations, consult local dealer or Electricity
Company.
