The best way to diagnose this is via the LED lights, how they act, which if any don't light or stay lit. You could have problems in the power supply as well as the "switch".

Try disconnecting hard drive, optical drive, AirPortcard, SD card reader and Bluetooth/camera/sensor cable(s) to determine if one of them ispreventing the power supply from functioning
