Re: Acer V17 Nitro no image
SIO DGPU_PWROK seems to be shorten internally in the ec . the resistance is 1 ohm. R8314 and D8301 are not present on the board. If i replace the NPCE285PA0DX does it need to be reprogrammed or it will reprogram from the bios?

I found that 1D05V_VGA_S0 is not present.DGPU_PWROK_R is 0. The signal DGPU_PWROK seems to come from pch.Can the pch be defective?Leave a comment:

Re: Acer V17 Nitro no image
I think that the pins on the connector are in odd number so the voltages are.
pin1 0.67
pin203 0.69
pin202 3.38
pin200 3.38
pin199 3.38
pin 75 3.38
pin 30 3.3
pin126 0.69Leave a comment:
