3.1 Suspend Timeout
The suspend timeout determines how long the computer will wait after any activity (key press, scan, or
touch screen event, or a wireless radio transmission) before it goes into suspend mode.
When the computer wakes, the device returns to the normal powered state. The backlight, the display, and
all peripheral devices turn on and the suspend timer begins counting again.
The suspend timeout is configured as an integer variable measured in seconds. Any value between 0 and
the maximum value of 2147483647 can be configured, however the GUI Power applet only allows a small
number of predefined values to be set. If you set the suspend timeout using the Mobile Devices SDK to a
value not on the predefined list, the GUI Power applet displays the default value for that setting.
The following tables list of predefined GUI Power applet suspend timeouts, and their corresponding integer
values in seconds:
