Identifying Low Battery Status
When battery power is low (10% or less), the power LED lights yellow (blinks in Standby
mode). When battery power is very low (3% or less), the power LED lights amber (blinks in
Standby mode). When your system is in a low battery status, do one of the following:
Save your work, power off the system, remove the spent battery, and replace it with a
fully charged battery.
Leave the spent battery in the system and connect your NEC Versa LitePad tablet PC to
the AC adapter and a wall outlet.
Returning the Battery to its Normal State
If battery performance drops, for example, you experience shorter work times, try one of the
following procedures to improve battery performance:
Remove and reinstall the battery in your NEC Versa LitePad tablet PC and fully
recharge the battery (to 100%).
Refresh the battery using the Battery Refresh function in the BIOS Setup utility (see
"Standard Menu" in Chapter 3 of the NEC Versa LitePad Tablet PC User's Guide).
Extending Battery Life
While on the road, it is important to be aware of the simple things you can do to extend the
life of the system's battery:
Keep the brightness setting low by adjusting the screen brightness in the Tablet and Pen
Settings menu. To adjust screen brightness, double tap the Tablet and Pen Settings icon
in the Windows system tray. Tap the Display tab to select Screen brightness settings.
You can adjust screen brightness for running the system on AC power and for battery
power.
Run storage devices, such as the USB CD-ROM drive or the optional USB CD-R/RW
drive, on AC power only.
Turn off the system when you finish using it.
Note
NEC Solutions America recommends that you always operate your system on AC
power when using any external device.
