I have LED 1 on. No other LEDs are ON Have PP1V05_S0_REG=0v C7416 has 4.3V on pin 1 and 0V on pin 2 Therefore U7400 0V on pin 10. Both the below read 0V. Therefore U7400 0V. SNS_CPU_VCCIO_P SNS_CPU_VCCIO_N They come from the CPU U1000 Ivy bridge. CPU issue??? PP1V05_S0_GPU_REG=1.5V U3815/...

Hi Yoel Thanks for your reply. I managed to find the short it was C9680. I have LED 1 on. No other LEDs are ON Have PP1V05_S0_REG=Ov C7416 has 4.3V on pin 1 and 0V on pin 2 Therefore U7400 0V on pin 10. Both the below read 0V. Therefore U7400 0V. SNS_CPU_VCCIO_P SNS_CPU_VCCIO_N They come from...

I have the same issue you had no LED lights PSU outputting @95% 11.82V All rails are good G3 Rails G3H Rails Also good is P12V_S5 and PP5V_S5 Problem is with PP3V3_S5

How did you isolate the capacitor that was shorted? How to determine whether U7600 is defective?

P5VS4& PP54_S4 has no shorts to ground when multimeter on diode setting P3V3S5 components are shorted to ground when multimeter on diode setting That is to say all pin on the left of the IC on the schematic is shorted but everything to the right except Vin is not shorted.

Hi There I have have the exact same issue like you have pp3v3_s5 short. U7600 Pin 1-3, 8-9, 11,13-14,18,23,25-28 =0V Pin 4-5 = 4.96V Pin 6-7, 24 = 0.4V Pin 10 =0.146V Pin 12 = 3.85V Pin 15= 4.6 Pin 17= 11.8 Pin 21 = 4.63
