Some keys of the keyboard are not typing

Some keys of the keyboard are not typing

Some of the keys of the row of Shift are not typing.
The Shift key on the left is non-functional.
But the Shift key on the right is functional.
The rest of the keys on this row are not typing except b & n.

What seems to be the problem and how to fix it?

Thanks.

 

you might need a new keyboard,, first check your keyboard in another pc to see if the issue still occurs.

if it does then it is the keyboard.

if not, then you can try the following which has worked for some people:

run your hands over all the keys (flat) a couple of times and see if that clears it up.

or you might get a can of compressed air and blow out the keyboard as some keys may not be making contact.
