Is there a way to wake Windows 8.1 from connected backup software? For my requirement, this is acceptable using the background task of a store application or session service 0.
My scenario is that I have a background task for a store application that will be called periodically (or launched by push notification). When a background task is called, it checks whether a certain condition is fulfilled. If so, it must perform an operation to wake the device from the connected standby mode. The reason I need to exit CS is because I need to start the process when the condition is met. This process will serve a TCP connection for continuous operation. This is similar to a remote desktop server that automatically wakes up when asked for a connection, but usually in connected standby mode to save power (the device is on battery).
The first approach that I think of is to use a scheduled task with the "wake the computer to run" option. But according to this message, he will not wake the car in standby mode in standby mode.
Now, if there is a way to do this programmatically, it would be logical to do it as a background task of a store application or a session 0 service, both of which get little opportunity to start while waiting for a connection. But the question is, what operation to perform to exit the connected standby mode?
According to the connected standby sources in standby mode , various peripheral devices can wake the device. For example, pressing the power button wakes the device through a GPIO interrupt. So the question boils down to whether there is a way to “simulate” a power button press by generating such a GPIO interrupt? I know little about programming the Windows kernel / driver. Any advice would be appreciated. I think this is an acceptable approach, since this WDTF method can transfer the system to CS and wake up after a given interval.
Another seemingly possible approach would be to create a toast notification as a “VoIP” application. As mentioned in Introduction to Connected Standby , the background task scheduled by the screen lock application can send a toast notification that ONLY generates a short beep when the display is off. Only after pressing the power button will a toast be displayed. Therefore, I suppose that generating toasts in this way will not awaken the device. However, the document mentions "VoIP" applications that can generate toast notifications with a longer one, customize the ringtone, and with the display turned on. I guess the device might be woken up in this case. But the document does not contain any reference to how such "VoIP" applications are recorded.
