xps 17 9700 does not correctly recognize the usb-c adapter

[stevetaylor]

Hi, I have an xps 17 9700 10gen cpu. It does not correctly recognize the usb-c adapter. If I attach a 130w charger, it sees it as 90w, if it is 90w, it sees it as 65w. It has 4x usb-C, they all behave the same. The laptop came from the factory with a 130w charger. Performance drops dramatically if it recognizes it as 90w. Do you have any suggestions?
It has the latest bios version.

USB-C designs are often using a dedicated microcontroller for the task. Review which part is onboard and check if there is a firmware update tool for this laptop. Reflash the firmware for this power delivery controller.

Post pics of this part of the logic board if in doubt. The part could be from Texas Instruments, Cypress, Infineon MPS, Richtek, ST, etc.
