Hi there, I am having the same issue many users have had with the UCM-UCSI ACPI Device error code 43, coupled with the USB C port not working and charging only when powered off. I started having this issue a week or so ago when I had to reinstall windows on my laptop via ISO because all of a sudden it started being really slow and nothing was working to get it running properly. I have done the following since reinstalling windows 10:
1. Updated basically all drivers from HP website
2. Updated BIOS
3. When all of that still failed to resolve the issue, I upgraded to Windows 11
4. Reinstalled Windows 11 via ISO just to be sure
I have googled this problem and have followed all troubleshooting instructions I found such as...
1. Uninstalling the device via device manager and then searching for hardward changes to reinstall it.
2. Powering off the laptop with the power cord removed, pressing the power button for 15 seconds, and then powering back up (soft reset)
3. Reinstalled drivers for display and USB
I don't know what to do at this point. Is this a hardware issue that just happened to coincide with the issues I was experiencing which precipitated the first windows reinstallation I performed? My laptop is only barely out of warranty at this point. I have received all Windows Updates that are available. What should I do next???
Edit - I just want to add that I was doing some further digging with this error and on a Microsoft forum someone posted that theirs turned out to literally be a dirty USB C port and after cleaning it out the driver issue resolved, and the port started working. I went to inspect mine for the unlikely event that it appears the USB C and charging ports aren't caked with dust or something, and in doing so I discovered what appears to be some warping of the case around the hinges on both sides. It's like something pushed outward from the inside. I recalled a few times when I opened or closed the laptop, I heard some cracking noises somewhere in the hinge area but since the hinge still functioned, I didn't think much of it. I have not dropped it or damaged it in any way. I don't even take it out of the house! I did some further digging and discovered that hinge issues are very common in Pavilions built since 2017.
