How can I fix or replace the switch that turn on the computer?
 
                I have a Dell XPS D266.  The power supply was replaced and tested, the mother board was also replaced. And the computer does not turn on.  I suspect that the switch that turn on the computer is broken.  How can I fix it, or replace it?  
If it is to be replaced, where I can buy the switch?
