OEMs can write applications that manage system power states directly, without customizing Power Manager. Such applications must disable both the Graphics, Windowing, and the Graphics, Windowing, and Events Subsystem (GWES) and Power Manager and handle power states themselves. For more information about disabling GWES and Power Manager, see Power Manager Suspend Timeouts.
Power Manager may not be able to determine the state that it should resume from a suspended state. If OEMs allow the system to resume fully after each suspended state, this may not be an issue. However, if they choose to have real-time clock (RTC) alarms that partially wake the system, they may need to modify Power Manager anyway.
