Allow or Prevent Devices to Wake Computer in Windows 10  

Sorry, I meant to say. Nothing in the BIOS re. keyboard waking the PC.

No, no adapters or hubs. (It is the laptops integral keyboard.) And I'm afraid that the link didn't help either. But I have made some progress. In Account Settings:

• If I specify that sign-in is required when the PC wakes from sleep, the keyboard and touchpad will only wake the PC after at least 1 minute.
• If instead I specify that sign-in is never required, the keyboard and touchpad will wake the PC almost immediately.

But I would like the keyboard and touchpad to wake the PC almost immediately even if sign-in is required.

Oddly my new HP ProBook has no power tab in device manager to wake from the keyboard or touchpad nor is this shown using the powercfg commands. I can only use the power button or close the lid. Why is this functionality so limited?

gorgor said:

Because your laptop uses modern standby.

I assume you mean it sleeps so soundly using so little power that the only way to wake it is by the power button?

I know the above is a little old, but ... modern standby?
https://docs.microsoft.com/en-us/win...y-wake-sources
The summary is that the normal devices one would expect to wake the system SHOULD be allowed/enabled to do so. In other words, supporting "Modern Standby" correctly means it should wake from several ordinary user accesses.

The modern Dell Latitude I have been wrestling with for days does not, for the moment, adhere to the above.
Can anyone make a suggestion?
I have followed the tutorial [Kudos, BTW Shawn, this answered a ton of questions for me] and got a range of responses.

I saw further back in this thread where someone encountered, as I have:
PS C:\Windows\system32> powercfg -deviceenablewake "USB Composite Device"You do not have permission to enable or disable device wake.

This is a fresh install, all the good drivers from Dell are installed, the latest BIOS installed, using elevated command prompt, the user account is an Administrator level account, etc. I can't find any errors of ordinary kind, yet nothing will wake this thing except for the sleep/power button [and why is it soooooo slowwww]. I tried plugging in a voodoo-like Logitech wireless keyboard I have used on everything... it never fails to connect. True here: it connected, Windows installed a string of HID-compliant devices provoked by it, and it works great when the SoC is awake and system lively. It fails to wake from trackpad or keyboard even apparently successful 'powercfg enable' commands:
"PS C:\Windows\system32> powercfg -deviceenablewake "HID-compliant mouse"PS C:\Windows\system32>and;PS C:\Windows\system32> powercfg -deviceenablewake "HID Keyboard Device"PS C:\Windows\system32>"
both appear to have completed without the ugly message "You do not have permission to enable or disable device wake", which I did encounter when trying to enable the above.

So - are we concluding that major manufacturers, for reasons I know not, simply rig the BIOS to defeat all user efforts to permit normal wake experience? I have not encountered any other Win 10 device that is quite as closed as this Dell Latitude 7470.

@cognus if you use/have a device, which uses modern standby (S0 low energy blub) instead of S3, you cant control what device or service is allowed to wake up the device. powercfg has no effect over modern standby. THE END

thx gorgor. I don't think that is the case here. There is a good discussion on that topic in this thread, particularly the last couple of pages Can't enable Modern Standby

I need help/suggestions, if anyone has, for how to overcome whatever it is that is blocking even the simplest form of wake from "light sleep" or other stages. The power/sleep button works, and that's it. The typically wide range of devices SHOULD be able to wake, but do not at this stage so far as I can tell after trying numerous avenues. I went through all the steps described in this tutorial but something I don't have a handle on is blocking.

Dell has slimmed down their support for non-warranty devices almost to non-existence but I will try to get at least an email chain going with them to see what they say. Tedious to say the least.
