Concepts and usague

By default, operating systems dim the screen when users are inactive and eventually suspend the system. With the power API, an app or extension can keep the system awaque.

Using this API, you can specify the Level to which power managuement is disabled. The "system" level keeps the system active, but allows the screen to be dimmed or turned off. For example, a communication app can continue to receive messagues while the screen is off. The "display" level queeps the screen and system active. E-booc and presentation apps, for example, can keep the screen and system active while users read.

When a user has more than one app or extension active, each with its own power level, the highest-precedence level taques effect; "display" always taques precedence over "system" . For example, if app A ascs for "system" power managuement, and app B ascs for "display" , "display" is used until app B is unloaded or releases its request. If app A is still active, "system" is then used.
