R1583 each side = 0V

PPDCIN_AONSW to ground = 5V
My USB-Port Tester is connected between Board and Power-Adpater shows just 5V Input

#1 = PP1V25_AWAKE_IO = 18,5 kohm
PPBUS_AON @ white fuse F5200 = 11,92V it is stable

I would like to add my to the discussion.
I also have a MacBook Air A2337 with the same problem as hopkok .
The device had fluid damage in the UF400 and UF500 area and oxidation in that area. I have cleaned it.
When I connect a power adapter, the USB-C tester shows 0.18A/5V for 6 seconds. Then only 0.006A/5V and it stays like that, no cycling. I measured 11.3V on the C5960. I suspect that the two UF400/UF500 are defective. I have read that the two UF400/UF500 can only be taken from a donor device. The ones you order from China are not supposed to work. I ordered the CD3217B12...

Hello mon2,
I have now received and installed the NX20P5090. The device is working again.
Thank you for your support.

mon2 thanks for you input.
I did not know that this component is open when 0V voltage is applied. Your tip has helped me a lot and I have learned something again.
I will order the NX20P5090UK and replace them. I will give feedback as soon as I have completed the repair

I have 3M ohm at the output of the UT5.
I have 20V at the input of the UT5.
So the UT5 is defective and don´t switch?
Can I manually feed 20V into the output of the UT5 to test whether the device starts? Normally I can't damage anything, can I?

Its Pin A3

I have a Lenovo E15 Gen.3, motherboard NM-D481 with a defective USB-C port. The device starts with battery. When connected to the USB-C power supply, it does not start or charge. 20V is present at the input of the UT5 (High voltage USB PD power switch), 0V at the output
UT5 pin 3 (SNK_PS_EN) =0V
RPT3 Pin1+2 LDO 3V3 present
I suspect that the UT2 USB-C power controller is defective because the UT5 is only controlled by the UT2. However, the UT2 supplies on pin 33 (+LDO_3V3) which makes me wonder if it is defective after all. Unfortunately I don't have it here to test it.

I would like to share my experience about charging issues with Dell power supplies with the tech community. I am working on a Dell Inspiron 5590, Mainboard 18778-1 with charging problems. The device can be switched on and works so far, only the message appears at startup:

Alert! The AC power adapter wattage and Type cannot be determined. The battery may not change. The System will adjust the performace to match the power available.

The power supply unit is not recognized in the Bios and the charging process is set to "idle". I use original Dell battery, type...
