PhilPhil, 1 Check LEDS DS7 and DS8 on the logic board. In a working unit, these LEDs should be in sync with each other: both on or both off. If one LED is on and the other is off, there is a problem. 2 Verify the power outlet is good. Try a known-good power cord. 3 Make sure the voltage switch on the back of the power supply is set to the correct voltage. 4 Check for +5V trickle voltage on pin 20 at the power supply connector, J23. (Pin 20 is the pin closest to the edge of the logic board and the front of the computer.) If there is a +5V reading, you know the power supply is likely OK. However, if there�s no +5V trickle power, replace the power supply. 5 Disconnect the keyboard and power-on the system via the reset button on the front of the computer. If the unit powers on, replace the USB keyboard. If not, go to next step.
