Chapter 6 Customizing Your PA500

Extending Battery Life
You can save your device’s battery life by doing either of the following:
• Change the automatic power settings
• Minimize the use of backlight
To change the Automatic Power Settings:
The PA500 will enter idle mode when there is no task, or all tasks are waiting for input. In default
setting, the PA500 will automatically turn itself off if it remains idle for 3 minutes and when there is no
external charging power applied. Pressing the power button will return the PA500 to the same point at
the time of automatic shutdown.
1. Tap Start → Settings.
2. On the System tab, tap Power.
3. Tap the Advanced tab.
4. Tap the “On battery power turn off device if not used for” check box and change the amount of
time before the unit turns off the backlight while running in battery power mode.
This function can also be activated when the PA500 is plugged into the power adapter or placed
in its docking station. On the Advanced tab, tap the “On external power turn off device if not
used for” check box and change the amount of time before the unit turns off the backlight while
running in external power mode.
