How can I change hotkeys in the BIOS?

I have a new laptop, and basic hotkeys like closing [Alt + F4] don't work.

Heard that you have to change this in BIOS mode.

Where exactly there?!

[Alt-F4] is pure Windows thing!

A hotkey can only be "intercepted" or changed using a keyboard driver or special software, maybe you did / installed something with keyboard macros?!

Again: Bios has nothing to do with it!

Without wanting to make the horses shy: a virus could also be the cause!
