Power Saving Modes
This section contains information on the DeskNote's power system,
including the AC Adapter, the battery system, recharging the battery,
and tips for conserving battery power. The power system is
comprised of two parts, the AC Adapter and the battery system. The
AC Adapter converts AC power from a wall outlet to the DC power
required by the computer.
The AC Adapter
The AC Adapter’s primary function is to provide power to the
DeskNote. If the AC Adapter is not functioning properly, please
consult your dealer immediately for support.
The Battery Power System (Optional)
A fully charged pack will provide approximately 1.0 hours of battery
life depending on your system configuration and the application it
runs. Using the power management features can extend the battery
life. Charging the battery takes about 4 hours to charge when the
system is in off state. If possible, always charge the battery
completely.
Battery Indicators
There are four LED indicators and one button on the upper corner of
the battery. These LED indicators designate different battery status.
