Windows 10: Pressing certain keys / combination of keys turns down brightness

I have a Surface pro with a detachable keyboard. Sometimes, the Fn button will stop lighting up, and when that happens certain keys/combination of keys will turn the brightness down a notch. I can't quite tell if its consistent or not, but for example, as I am writing this, hitting the space bar or the A and S key at the same time turns the brightness down. It usually happens with some combination of the W, A, S, D, and F keys. However, the Fn key will sometimes start lighting up when pressed like usual and things will go back to normal.

Changing brightness is no longer smooth with function keys on 1903

Hi, There's a the slider for brightness at the bottom of the Action Centre (build 1903).

If you'd be prepared to consider an alternative... how about smooth control of brightness using your scroll wheel?
Press a key, plus scroll, and adjust your brightness.

The key and the steps are your choice.

Oh, and it can adjust volume similarly.

Works nicely on my Lenovo Thinkpad, where the Fn key steps for brightness are a bit harsh.

Booting without press any key

@dhievm go ahead and list the model number that gives exact specs/info.


Does it stop right at the Toshiba logo and sit there? Will it sit forever til you press a key, or will it eventually work after so long?

 

Key combinations confusion

Maybe it would help if I illustrate my question with an example.

Currently, if I press Win+Up on my laptop, a MaximizeWindow is executed. However:

• If I execute Win+/ (to display all key combinations involving the Windows key), Win+Up says "No action" (which isn't correct, because it executes MaximizeWindow).
  
• And, if I go into PowerToys / Keyboard Manager, Keyboard Manager is enabled but there are no key combinations listed under either Remap A Key or Remap a shortcut.
  

So, how was Win+Up remapped? And where should I remap it, if I want it to do something else? Any why isn't it showing up when I press Win+/?
