Windows 10: Arrow keys not working without holding the Fn key even in the bios and controlling...

Hello, Everything was working just fine a couple of hours ago and now I have to press and hold the Fn key to use the arrow keys up, down, left, right, and without holding the Fn key, up and down increases and decreases the brightness, and left and right controls the volume.Before this, I had to press and hold the Fn key to control brightness and volume and the arrow keys were working as usual, so looks like it has been inverted.my daughter, 3, was watching cartoons, so I think she might have pressed some buttons and changed some settings in the process.System Details:Operating System: Wind

FN key always on

To clarify, I was saying "Accessibility" features maybe be controlled via the BIOS, not the Fn keys. And one of the Accessibility features makes the keys "sticky". This allows folks with some disabilities to press, for example, the Ctrl key, then the Alt key, and then Del in sequence instead of all at once. Same with the Fn key. The sticky feature would let you first press the Fn key, and then the F9 key (for example) and not Fn + F9 at the same time to enable/disable whatever Fn + F9 does with that notebook (it is the touchpad on my Toshiba).

 

FN key always on

If you press “Num Lock" (might also be labeled "Num Lk”) (I’ve also seen it labeled “Pad Lock” for numeric Pad) it turns on the blue keys, and inverts the meaning of the “Fn” key – it’s a way to use that embedded numeric keypad without having to hold down the “Fn” key the entire time. To fix it, just find and press the “Num Lock” or “Pad Lock” key again. (Note, sometimes these keys are themselves “Fn” keys, so you may, or may not, need to also hold down the “Fn” key to get the right function.) Often there is an indicator light associated with the setting.

 

down arrow key stopped working

My razor lycosa down arrow key decided to not respond at some point today. The other ones work and so does the numpad arrow if i turn off the numlock. Sounds like its just broken and im screwed, but any suggestions?
