POWER MANAGEMENT OVERVIEW
Power Management in the NEC Versa lets you conserve energy, save battery power, extend
the life of your LCD backlight, and protect against data loss due to low battery power.
Set some features to function automatically or activate them manually with the keyboard or
a button. It is wise to keep Power Management features enabled, even when using AC
power.
The system ships with many power-saving features already enabled. See the following table.
