laptop: Dell Inspiron 7370 - win10

I want to WAKE laptop out of sleep mode using keyboard. In fact, I can wake it if my mouse is plugged, but without a mouse, I have NO WAY to wake the laptop. (a living dead)

Most of the time I close the lid (forget to take a mouse), and after a while, I find can do nothing to wake the computer but only shut it down compulsorily then restart.

So I go to change the setting of the keyboard: Device Manager -> HID Keyboard Device to "Allow keyboard to wake up computer". However, unlike my mouse, there are no power management tab for keyboard. (I have enabled the “USB wake up” in BIOS)

 

 

An answer from Re: no power management tab for keyboard - dell xps, windows 7  said the keyboard of my laptop doesn't support a WAKE function (different from the pic below, which support a wake function)

 

 

So does it mean I can never wake my laptop if I don't bring a mouse with me? It's crazy that a laptop cannot be woken up from the embedded keyboard.

Is it a bug from Microsoft or Dell? Hope someone can fix it~
