In Power Options - Advanced settings - Sleep - Allow wake timers: I have changed it to Disable for both battery and plugged in.

This solution has been suggested to prevent the computer from waking up by itself.

What happens when I disable "HID keyboard device is allowed to wake up computer"? And what are the consequences?

Does that mean it only wakes up from the power button? What else?

info: OS: Windows-10 PC: Dell Alienware

  • HID devices (if enabled) allow you to wake the computer using a keyboard or mouse. – DavidPostill May 10 '20 at 14:11
  • Does this answer your question? Computer wakes up from Sleeping Mode – somebadhat May 11 '20 at 11:55
  • @somebadhat No to a certain extent. My question was specific about the HID Keyboard, what happens and what are the consequences form disabling it? Knowing that the my computer already does not wake up from the Keyboard and Mouse. I think Austin's answer, below, is fair enough, unless someone else wants to chime in with some other details. – Mohd May 11 '20 at 12:50

TL;DR:

Probably not much other than not being able to resume from suspend and/or hibernate by hitting a key on the keyboard.


A bit of extra background for why it's just 'probably':

HID is a communications protocol primarily designed for input devices (keyboards, mice, game controllers, etc) intended to be independent of the underlying connection (HID is used over at least USB, Bluetooth, ZigBee, and I2C, and possibly other hardware interconnects). Most modern USB and Bluetooth input devices are HID devices, though some laptops continue to use PS/2 internally instead of USB+HID for their keyboard and touchpad for power efficiency reasons.

The thing is, the HID protocol isn't just used for actual input devices. The protocol itself is rather lax, and quite a few things present as HID devices that either don't fit what many people think of as input devices (for example, audio controllers or USB-connected phone handsets (for use with VoIP systems)), or that quite simply aren't input devices (a lot of USB connected uninterruptible power supplies and software protection dongles are also HID devices). Some of these devices present generically as a keyboard or mouse instead of something more specific.

As a result of this, it's possible that the physical device listed as 'HID Keyboard' may not actually be a keyboard, and may serve some other function in your system, in which case disabling wakeups from that device may either do nothing at all, or might actually cause something to stop working (though this is very unlikely). However, unless you see more than one keyboard listed this is exceedingly unlikely.
