x15 R2, USB ethernet adapter causes Touchpad to stop working
This is a weird one. I connected a USB-C Ethernet adapter to one of the USB-C ports on the back of my x15 R2, then connected the ethernet cable. Suddenly, the Touchpad becomes highly erratic, not tracking, touching it causes all sorts of gesture actions to happen, just completely unusable. Tried 4 different USB ethernet adapters (USB-C and USB-A).
Even more weird is if I just unplug the ethernet cable from the adapter (leave the ethernet adapter plugged into the laptop), the Touchpad is restored to normal! WHAT?
WiFi ON does not cause this to happen so it does not seem to be some sort of internet / software issue.
Also when the Touchpad is unusable, a USB corded mouse works perfectly.
I can't figure this one out and I'm an IT person! Windows 11 fully updated with Windows update.
Anyone have any ideas?
OK, this is straight out of the Twilight Zone! I discovered when I moved my X15R2 about 4 inches, the trackpad started working! Moved it back, stopped working. I'm using this on my workbench, which has a giant gaming mousepad on it to protect surfaces, etc. Nothing electronic under the desk. But literally pushing the laptop back 4 inches and the trackpad started working. I moved it to a different bench (still with a giant gaming mousepad to protect, and it works fine with USB-C ethernet.
Oddly, a couple times when I turned it on, the keyboard stopped working. No lights, no function.
I removed the cover and battery and inspected the keyboard/trackpad controller board and connections look solid. Put back and everything is working again.
So, what is it about where the laptop was that was causing the initial issue and why would placement affect WIRED ethernet?

I had a 2nd unit (exactly the same config) that was still unopened, so I fired it up and didn't do anything but the initial account setup in Windows 11. Got to desktop, plugged in USB-C ethernet adapter with cable and trackpad stopped working.
SOMETHING IS WRONG WITH THIS MODEL.
