Configuring the Power Management Options
To help you get the optimum performance out of your unit, it comes with
predefined sets of parameters (plans) to manage power.
When you do not use the unit for a while, the display may be dimmed or
turned off to save power. You can also configure the unit to go into sleep
mode after the specified duration has expired (see Turning Off Your Unit on
page 36).
For all of these actions, you can set idle durations for AC adapter/charger
and battery operation. The values that you set are kept in memory even
when you turn the unit off.
Note: When the backlight is turned off and the LED is lit and not blinking, the
unit operation is not interrupted. Touch anywhere on the screen to return to
normal operation.
The table below identifies the predefined power plans.
You can either modify one of the existing power plans or create one (based
on an existing power plan). It is always possible to revert to factory default
values for the predefined plans. You can delete custom power plans that
you no longer use, but not the predefined plans.
Power Plan Characteristics

it, and saves power when your unit
consumes less.
High Performance Provides maximum power, which could be
particularly useful when you intend to work
modules requiring extra power.
Power Saver Optimizes the energy consumption, which
could be particularly useful when you
operate the unit on batteries.
