Since the last week I have a problem with the keyboard. Button "W" is not responding at all when I press it. At the same time, if I press a button close to it, for example "E" or "R", "E" or "R" is typed correspondingly, but "W" also gets stuck and is typed like crazy until I stop this by pressing another button. As far as I know, nothing has been spilled on the keyboard, given that I am the only user of the notebook. In addition to this, there is not much dust in my appartment. Any ideas why is this happening? Washing the keyboard, before buying a new one, could be a solution? Does anyone know how to remove the keyboard? I watched a few videos in youtube, but I didn't manage to remove it. Of course I am out of the guarantee period.
