Windows 10: 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 the

Shift Key Changes Capitalization

When I happen to by needing to use the shift key while editing text in most Office applications, the shift key changes the capitalization of the word. Press it once and the first letter comes capitalized, and I think the whole word becomes capitalized if
you press shift again. This is insanely irritating, because anytime you are using any keyboard shortcut or anything that requires the shift key, it changes the capitalization status of your words.

How do I turn off the ability of the shift key to change capitalization?

 

Capital m key not working online

I have noticed that my capital m key has stopped working online. When I press left or right shift and the m key it doesn't register a capital w on internet explorer but it does with every other key. Also, the lower case m does register but the capital.
It does register a capital m offline in notepad etc. however not online.

 

Can't type certain capital letters with the left or right shift, depending!

So there are some similar posts i've seen that had issues like mine, but nothing quite exactly the same.

I can type all the letters just fine in lowercase, without any noticeable issues, or in uppercase with caps lock on. But when it comes to using the shift keys, the only way I can type a capital "A" is with the Right shift key (left doesn't produce any characters),
and the only way I can produce a capital Q is with the Left shift key. This is Quite irritating and nonsensical.

As other posts have stated, I've not installed any software or hardware anytime recently either, and haven't had any updates to speak of that could have caused this to my knowledge.

I am operating a Lenovo Yoga 700-11ISK with Windows 10 up to date as of this posting.

HELP!!
