Setting the policy controls the power management strategy when the user idles.
There are 4 actions:
* The screen dims if the user is idle for the time specified by ScreenDim.
* The screen turns off if the user is idle for the time specified by ScreenOff.
* A warning dialog appears if the user remains idle for the time specified by IdleWarning. It warns the user that the idle action will be taken and only appears if the idle action is to sign out or shut down.
* The action specified by IdleAction is taken if the user is idle for the time specified by Idle.
For each of the above actions, the delay should be specified in milliseconds and must be set to a value greater than zero to trigger the corresponding action. If the delay is set to zero, Google Chrome OS won't take the corresponding action.
For each of the above delays, when the time is unset, a default value is used.
ScreenDim values will be clamped to be less than or equal to ScreenOff. ScreenOff and IdleWarning will be clamped to be less than or equal to Idle.
IdleAction can be one of 4 actions:
If the IdleAction is not set, Suspend is taken.
Note: There are separate settings for AC power and battery.
