When I click to type anything, say, in the Chrome search bar, a Word document or a Facebook post, before I touch any key my Samsung laptop will automatically type loads of the figure 9 until I stop it by pressing the backspace bar.
It'll then be OK until the next time I attempt to type something, but often it won't do it for quite a while.
My computer is virus-free so I can only think that it's a fault with the '9' key itself. I'm computer literate but not technical, so I've no idea how to go about checking if the key is faulty and how to get it fixed. Can anyone offer any advice?
I have tried connecting an external keyboard to the computer - the same thing happens.
Many thanks in advance.
