Trackpad sluggish when ethernet is connected
When I connect an ethernet cable to my ThinkPad P14s Gen4 AMD depending on what is on the other end of the cable, the trackpad becomes sluggish. When I move the cursor via the trackpad it's kind of "drifting" with movement.
It seems like the STP cable carries some high frequency AC to the ThinkPad. When I touch the metallic plug of the cable, the trackpad is immediately snappy again. If I use an UTP cable it doesn't happen.
I tried to ground the ThinkPad via a USB-C power adapter that has grounding, but it didn't change the situation. Do you think a USB-C travel dock can fix the issue or a female/female ethernet adapter with a short UTP cable?
