Using The Battery; Charging The Battery; Low Battery Power - NEC VERSA E6500 Series User Manual

Using the Battery

Note
Although the battery is fully charged at the factory, transit and shelf time may reduce the
initial battery charge. We recommend that the first time you use your notebook, you connect it
to AC power using the AC adaptor. This also recharges your battery.
When the battery is used to 10% of its capacity, the Battery Charge Indicator will start
blinking and the notebook will beep a warning. Always respond by immediately saving your
data, and connecting your notebook to the AC adaptor. If an AC adaptor is not available,
change the battery using the battery replacement procedure. Refer to the section on
"Replacing the Battery" for details.
If you do not take any action, the notebook will automatically go into Hibernation (Save To
File) mode.
WARNING
To prevent accidental battery ignition or explosion, adhere to the following:
Keep the battery away from extreme heat.
Keep metal objects away from the battery terminals to prevent a short circuit.
Make sure the battery is properly installed in the battery bay.
Read the precautions printed on the battery (if any).
Remember to unplug the AC adaptor cable from the power port on the notebook and from
the grounded AC power outlet after your notebook is fully charged, when your notebook is
not in use or when you know that your notebook will be unattended for long hours.
Do not disassemble the battery.

Charging the Battery

Charge time depends on whether or not you are using the notebook.
For maximum battery performance, fully discharge the battery before recharging it. To do so,
unplug the AC adaptor, turn off power management features (through BIOS Setup and
®
Windows power management), and turn on the notebook. Once the battery is fully
discharged, plug in the AC adaptor and recharge the battery.
The warning beep that sounds when battery power becomes critically low is always a true
indicator that battery power is low. Be sure to save your data when you hear the beep and
take proper steps to provide power to your notebook.
Precautions for Recharging the Battery
Adhere to the following precautions when recharging the battery.
• Use only the battery charger designed for your notebook battery type. Different NEC
VERSA models require different batteries and battery chargers.
• Charge the battery for the specified charge time only.
• During charging, keep the environmental temperature between 5°C and 35°C.
• Read the instructions that come with the battery charger before charging the battery.

Low Battery Power

When battery power gets low, connect your notebook to the AC adaptor.
If no AC adaptor is available, change the battery using the battery replacement procedure.
Refer to the section on "Replacing the Battery" for details.
