I have an Asus k541u laptop purchased in dubai by a friend last october. He came home in december. I have been using my laptop now mainly for multimedia and video editing then 2days ago, the keyboard started acting strange. Whenever i type, the asterisk randomly appears, until it so happens as if shift+8 (command to trigger *) has been jammed and ****************** starts happening. Some people say it's just dust and my keyboard needs cleaning. I did clean with a brush and not the letter K isn't working.
