The POWER_ACTION enumeration identifies the system power actions that can occur on a computer.
PowerActionNoneNo power action is taking place.
PowerActionReservedReserved for system use.
PowerActionSleepThe computer is entering a system sleeping (S1, S2, or S3) state.
PowerActionHibernateThe computer is entering its hibernation (S4) state.
PowerActionShutdownThe computer is entering its shutdown (S5) state. After all devices have entered their off (D3) state, the computer remains powered on until an administrator presses the power button.
PowerActionShutdownResetThe computer is entering its shutdown (S5) state. After all devices have entered their off (D3) state, the computer automatically powers off and then immediately restarts and returns to its working (S0) state.
PowerActionShutdownOffThe computer is entering its shutdown (S5) state. After all devices have entered their off (D3) state, the computer automatically powers off.
PowerActionWarmEjectThe computer is being ejected from an ACPI-compatible dock device. Typically, the computer's power state does not change.

PowerActionDisplayOff[Warning: UMDF 2 is the latest version of UMDF and supersedes UMDF 1. All new UMDF drivers should be written using UMDF 2. No new features are being added to UMDF 1 and there is limited support for UMDF 1 on newer versions of Windows 10. Universal Windows drivers must use UMDF 2. For more info, see Getting Started with UMDF.]
