Voltage to ground of pin 5 on PU101 is 3.294VDC -
Before I was using the JUSBC2.
I do not have the battery connected and I believed it is completely dischargeLeave a comment:

using JUSBC1 PORT
Voltage to ground
PD300 pin 2 = 4.730VDC
PU300 pin 17 = 8.03VDC
PL302 pin 2 = 4.730VDC
PD301 pin 2 = 8.38VDCLeave a comment:

Voltage to ground
PD300 pin 2 = 0.015vdc
PU300 pin 17 = 0.0015VDC
PL302 pin 2 = 0.005VDC

The readings were taken with the power adapter connected.Leave a comment:

Battery connected pins 2-3-4-5 reads 0.004VDC
PQ307 pin 7 measures at PL301 pin2 = 0vdc
PQ307 pin 2 measures at PR304 pin1 = 0.003vdc

Thanks SMDFlea!
It seemed to flux. Most likely it was reworked. I will review that area again.Leave a comment:

Pin 2, 3, 4 and 5 all reads 0VDC.Leave a comment:

Thanks mcplslg123.
myth77, the picture is the light from my microscope.
I will look again if there are any burns.
It just strange because the laptop fan spins and the CPU and GPU is warm when you press the power button but no post no imageLeave a comment:

Hey mon2,
Voltage measurements on PU500
Pin 17 = 0VDC
Pin 11 = 0VDC
Pin 12 = 0.266VDC
ThanksLeave a comment:

Thanks again mon2. The following were taken from PD104 pin 2 and pin 3.
[B]PBAT_CHARGER_SMBDAT = 0VDC
PBAT_CHARGER_SMBCLK = 0VDC[/B]Thanks again mon2. The following were taken from PD104 pin 2 and pin 3.

Thanks mon2
I saw all the traffic from a working USBC. Do I need to reprogram the USBC controller chip. How will it negotiate the 20V? I guess I have to find a way to program the firmware on the new pd chip....Leave a comment:

Any help guys!Leave a comment:

@ anhbanxoi, I injected 0.8V at PL501and there is 0 current draw.Leave a comment:

Hey mon2,
I attached the traces from each USBC port.
Thanks again...Leave a comment:

Thank you anhbanxoi. I measure the resistance of all the coils to ground.
PL501= 31 Ohm
PL504 = OL
PL302= OL
PL301= OL
PL1110 = 3 Ohm
PL1105 = 1 Ohm
PL1103 = 1 Ohm
PL1102 = 1 Ohm
PL1100 = 8 Ohm
PL701 = 54 Ohm
PL601 = 238 Ohm
Thanks again for helping.Last edited by waakye; 09-21-2024, 05:09 AM.Leave a comment:
