Extending Battery Life

Changing the Automatic Power Settings
The PA600 will enter idle mode when there is no task, or all tasks are waiting for input. 
In default setting, the PA600 automatically turns itself off if it remains idle for 3 minutes 
and when there is no external charging power connected. Pressing the power button 
returns the PA600 to the same point at the time of automatic shutdown.
To change the automatic power settings:

2. Tap the Switch state to User Idle, 
Switch state to System Idle or Switch 
state to Suspend to select from a list of 
time periods. The available time periods 
are 1, 2, 3, 4, 5, 10, 30 minutes and 
never.
3. This function can also be activated when 
the PA600 is plugged into the power 
adapter or placed in its docking station by 
tapping the Power Scheme to select AC 
Power and then tapping the arrow to 
select from a list of time periods. The 
available time periods are 1, 2, 5,10, 15,
