Need HP 500 Slate Tear down instructions for power on button

My HP Slate 500 was working fine but after last shut down, the power on button (upper rt slide switch) just moves down, will not spring back up, and the hp slate does not turn on. It was not dropped or damaged at all, just a switch and or spring problem. I am good with repairs, if I have instructions can I open the case and replace the switch assembly (part from you) or possibly correct the spring and/ or contact problem? Any help? from dbinma@cs.com
