Dear All,


The motherboard is working with battery (usb ports not working.)
first when it is came one of the USB-C CD3217B integrated circuits was short-circuited, so I replaced it. Additionally, I programmed the U301 integrated circuit.

Currently, I'm getting a voltage reading of 20V 0.06A from all ports on the motherboard. When the battery is connected, it shows the voltage outwardly on a USB testing device. As I mentioned, the T2 is working because the device turns on and enters the system without any issues using the battery. Apart from that, C7865 has a voltage of 3.3V, and the input side of the FET at the battery charging port shows 12.2V. The situation is the same for all ports. Does anyone have any ideas?

Thank you so much

First of all, welcome to the forum!

Do you get PPBUS_G3H and 3V3_G3H_RTC with charger alone (no battery)?
What is U301?
Did you get CD3217 chip from A2141 scrap board?
