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 system, you connect it to AC power using the AC
adapter. This also recharges your battery.
When battery power reaches 10%, the Battery Charge Indicator blinks and the system beeps a warning.
Always respond by immediately saving your data, and connecting your system to the AC adapter. If an AC
adapter is not available, change the battery using the battery replacement procedure.
Refer to Replacing the
Battery section for details.
If you do not take any action, the system 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 adapter cable from the power port on the notebook and from the grounded
wall 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 system.
For maximum battery performance, fully discharge the battery before recharging it. To do so, unplug the AC
adapter, turn off power management features (through BIOS Setup and Windows
®
power management), and
turn on the system. Once the battery is fully discharged, plug in the AC adapter 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 system.
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 system to the AC adapter.
If no AC adapter is available, change the battery using the battery replacement procedure. Refer to
Replacing the Battery section for details.
