Doesn't take keyboard input and hangs at the time of typing

And if you type in a notepad or likes does it do the same problem? If so then you got keyboard problems if that is the case. So does it do it then?

At the same time my typing works perfectly anywhere in Laptop like another web browser, notepad, IDE etc.
