Could we also establish exactly what it is that isn't working?
Everyone (including me) seems to have concentrated on the touchpad but the title of the question also includes 'keyboard'. (Somewhat confusingly, that becomes 'keypad' in the main text. If it wasn't a laptop I'd take that to mean a numeric keypad, rather than the whole keyboard but, as most laptops don't have one, I'm not so sure!).
If absolutely nothing that you can press, click or move your finger over is working, I'd suggest that it's almost certainly a connection fault.
