Yes the lights come on when started but that is it cd tray opens no lights when fn and cap locks button pushed coul it be keyboard bad , but why no beep code when mem is removed . Can the keyboard be unpluged and use usb kboard or will the laptop not bboot without it , shouldnt I be able to use external screen evev if the one on the laptop is bad ?
