Within range, use Companion Device Manager.Ĭertain apps need to keep the screen turned on, such as games or movie apps. If you need to keep your companion app running whenever a companion device is To trigger these services at specific intervals. If your app relies on background services, consider using If your app is synchronizing data from an external server, consider creating a If your app is performing long-running HTTP downloads, consider using Alternatives to using wake locksīefore adding wakelock support to your app, consider whether your app's useĬases support one of the following alternative solutions: Incompatible with the requirements of your app. The following sectionsĭescribe how to handle the cases where the device's default sleep behavior is Of thumb is that you should use the most lightweight approach possible for yourĪpp, to minimize your app's impact on system resources. The approach you take depends on the needs of your app. Note that USB debugging is not required to run scrcpy in OTG mode. Or the CPU and keep it awake to complete some work. However, there are times when an application needs to wake up the screen But the document doesn't provide any reference to how such "VoIP" apps are written.To avoid draining the battery, an Android device that is left idle quickly fallsĪsleep. I assume the device might be waked up in this case. However, the document does mention "VoIP" apps can generate toast notification with longer, customize ringtone, AND with display turned ON. So I assume generating toast in such a way won't wake up the device. Only after the user pressing the power button will the toast be shown. As mentioned in Introduction to Connected Standby, a background task scheduled by a lock screen app can send toast notification, which ONLY generates a short sound with the display turned off. they may be named differently but here is a snip of the ones on my NIC, sometimes disabling one of the wake options will still allow the remote wake but. I think this is a feasible approach as this WDTF method can put the system into CS and wake up after a given interval.Īnother seemingly possible approach would be to generate a toast notification as a "VoIP" app. One easier method might be to disable the WOL option in the NIC, if your Network card has this function they will be in the local area network - properties-confugure dialog. So the question boils down to is there a way to "simulate" a power button press by generating such GPIO interrupt? I don't know much about windows kernel/driver programming. For example, power button press wakes up the device through GPIO interrupt. But the question is - what operation to perform to exit connected standby?Īccording to Connected standby wake sources, various peripheral hardware can wake the device. Now if there is a way to do this programmatically, it would be logical to do this as a store app background task, or a session 0 service, both of which get a short chance to run during connected standby. But according to this post, it doesn't wake the machine when in connected standby mode. The first approach I think of is using scheduled task with the "wake the computer to run" option. It's kind of like a remote desktop server which automatically wakes up upon a connection request, but normally in connected standby to save power (the device is on battery). This process will serve a TCP connection to run a extended period of time. The reason I need to exit CS is that I need to launch a process when the condition is met. If so, it shall perform an operation to wake up the device from connected standby. BTW there is no 'Power Management' settings in my BIOS. I have attached both photos and yes, I was referring to the device manager. List your laptop make, model, screenshot of device manager with what's listed for KB and mse. Now, open up the Wake-on-LAN app on your phone, tap your device, and it should turn on within a few seconds. By default KB /mse should wake it with no further action. Instead of choosing, Shut Down choose Sleep, and wait for your PC to go into the low-power mode. When the background task is invoked, it checks to see if a certain condition is met. Go to your wakeable PC, click the Start menu, and then the power button. My scenario is that I have a store app background task to be periodically invoked (or be triggered by push notification). where the computer can be 'sent to sleep' at any point and will 'wake up'. Is there a way to wake up Windows 8.1 from connected standby programmatically? For my requirement, it's acceptable by using either a store app background task, or a session 0 service. 2.3 NETWORKED PCS Each PC on a network is called a 'workstation' or 'terminal'. Once rebooted into Windows, click the Start menu and search for 'Device Manager.' Launch the Device Manager, find the Network Adapters section, and expand it to.
