However, the standby mode is not common.

Use the power management API

Bool winapi setsystempowerstate (
_ In boolFsuspend,
_ In boolFforce
);

Parameters Fsuspend[In]

The parameter is ture system suspension (suspend); the parameter is false, and the system disk is in standby mode (hibernate)

Suspend indicates that the current system parameter is saved to the memory, and the CPU power is still on.

Hibernate is saved to the hard disk, CPU power off

Therefore, the standby and wake-up modes of suspend are faster than those of hibernate.

Fforce[In]

Invalid
