I am working on a compaq presario 700, when it powers up it runs fantastic. However, once you shut it down it will not start back up. This does not happen all the time, it happens about every other time. It is getting power, but aparently not to the board. No fans run, no battery sniffer, nothing. The only reason I know that it is getting power is because the "on" light is on, on the bottom of the screen. I have checked the voltage at the input for the power supply and it is correct. Any suggestions would be appreciated.
