    \015\012
  1. Make sure the voltage selector (which is located on the back of the power supply) is set to the correct voltage for your region.
  2. \015\012
  3. Remove the expansion cards one at a time until the 3.3V auxiliary\015\012light on the system board turns on. If removing a card turns the light\015\012on, replace the card and then see if the system works.

My HP Pavilion dv9005us has two issues which I cannot resolve. The wireless device is not even recognized or detected by the computer, and there seems to be an electrical problem where the lighted buttons at the top flicker on and off from time to time, which may also be linked to an issue where the computer will at times refuse to turn on after I press the on button and watch it all light up in response and immediately shut off. Any help with this would be greatly appreciated.
