My [url=http://www.acompatible.com/series/41-dell-precision-keyboard#model]Dell Precision Keyboard[/url] and mouse have stopped working on my Hp laptop, but the portable keyboard (which I have had to use cause my laptop keyboard letters 'b' and 'n' broke). I don't know what happened all I know was that before I fell asleep while playing on it, the keyboard and mouse worked perfectly. Now I can't even do Amything because the mouse doesn't work and you can only use the portable keyboard. Please help cause i don't know if ji hit a button to make it happen or what!
