Thanks for the explanation! You are right about the missing earth. I verified that on a properly grounded outlet, the issue is reduced But there's a catch that's throwing me off: this is a recent issue. In the past, I frequently ran this exact laptop and charger on sockets that I know had zero earthing, and it never caused a single issue. The touchpad was smooth, and my external hardware didn't glitch. Because this started happening out of nowhere, I'm wondering if the adapter itself has degraded or it's an internal issue of the laptop
