我在PowerButton驱动中加入SetSystemPowerState( NULL, POWER_STATE_OFF, POWER_FORCE );
就会打印如下的信息,然后屏幕就像挂起的样子,貌似没有什么区别。那我什么时候切断整个硬件上的电源合适呢?
PWR_IST: pPWR->State = 0x2
PMGET! System Power state is 'on', flags 0x00010000
>>>>>>>>>>>>>>>>>>> state == on <<<<<<<<<<<<<<<<<<<
!!!!!!!!!!!! BACKLIGHT OFF !!!!!!!!!!!!
BAK: IOCTL_POWER_SET: D4
CAMERA: CIS_PowerDown
CamClockOn = 0
CIS: IOCTL_POWER_SET: D4
