Windows 10: The N key doesn't work unless I hold shift for capital N or caps lock shift n for lowercase...

The N key doesn't work unless I hold shift n for a capital N or caps lock shift n for lowercase. All other keys work normally. Any ideas how to fix this?

Unable to make capital "n" using the left "shift" and the capital "m" with the right "shift"!

Yesterday I removed and put back after 5 minutes the battery of my ASUS VivoBook Pro 15 N580GD with win10 64bit.

After that, everything seems to work normally except I can't make the capital "n" using the left "shift" and the capital "m" with the right "shift"!

But both work with the other "shift": the "n" with the right one and the "m" with the left one. Lowercase "n" and "m" work normally. All the other letters I can do them capital with both the left and right "shift".

But what is even more absurd is that I can do both the "n" and the "m" capital with the non-working "shift" by following these steps: I keep pressed "shift" then I keep pressed the "n" (or the "m"), when I release "shift" the letter in capital magically appears

Anyone have any idea what that might be and how to fix it?
