Issues with USBC charging port driver

[Bubbletz]

HI, 

Recently I was unable to charge my laptop through the USBC port. It was after several updates this happened. I read reviews and forums followed the guide to go into device manager and found an issue with the UCM-UCSI ACPi Device. It has a yellow triangle. I followed the steps of uninstalling and trying to update drivers didnt work. I then went onto the HP website when trying to enter my operating systems which is windows 11 but my version is not available on the website. the version i have is 24H2 (OS Build 26100.4484).  I am now stuck I have followed all the steps that I can and unable to resolve this. Can someone please help and guide me on how to fix this. There is also the same triangle under Firmware and then HP R70 system firmware

Usually indicates driver or firmware incompatibility.

Attempt Basic Reset Steps First

Shut down the laptop.

Unplug power adapter and remove USB-C devices.

Hold down the power button for 15–20 seconds to discharge static and reset EC (Embedded Controller).

Update Using HP Software

Use HP Support Assistant

Download or open HP Support Assistant:

Let it scan for updates.

Install anything related to:

BIOS / Firmware

Thunderbolt / USB-C

If it doesn’t find anything:

Fix Drivers Directly via Device Manager
