Two solutions for the power supply and the signal light after Win8 is turned off

When the Windows 8 notebook is performing the shutdown action, the power indicator and other indicators will be on for several tens of seconds, even a few minutes after the screen is turned off. This phenomenon is actually caused by the mixed shutdown characteristics of Windows 8, and is not a malfunction. On the Windows 8 system, in order to get faster switch speed, Microsoft introduced a new hybrid shutdown mode.

Method 1:

The general flow of hybrid shutdown:

1, click “Shutdown”.

2. Windows Broadcast runs the application shutdown information, allowing the application to save data and settings. The application can also ask for some extra time to end its current work.

3. Close the screen.

4. Windows closes the user session for each logged in user.

5, the system session sleeps, and the power is turned off.

The process of traditional mode shutdown:

1, click “Shutdown”.

2. Windows Broadcast runs the application shutdown information, allowing the application to save data and settings. The application can also ask for some extra time to end its current work.

3. Windows closes the user session for each logged in user.

4. Windows sends a shutdown message to the service, notifying that the shutdown has started, and then shutting down the service. If the service does not respond, the system will force the shutdown.

5. Windows broadcasts information to the device, indicating that the device is shut down.

6. Windows closes the system session (also known as “session 0”).

7. Windows refreshes the system drive pending data to ensure full save.

8. Windows sends a signal to the system through the ACPI interface to power off the computer.

It is visible that Windows 8 only closes the user session and does not completely shut down the computer as before. At this point, Windows no longer waits and ends the system service and closes the session, but puts it to sleep. For different computers, including the same model and the same configuration computer, but the software configuration is different, the reason why the indicator lights are different each time the shutdown action is performed and the shutdown screen is turned off.
