Antwort auf „USB problem("This device could achieve higher performance")”I would venture a guess that it is a "Thermal Heatpad" issue because of the use and the time of the laptop, most people could possibly fix this on their own. The problem would be to make sure you do not mix up the screws if you figure you might want to take the small risk. The heatpad has stretched under the heat and it not doing it's job of being a silicon gasket as best it can. Numerous Youtube videos hint at this common issue but only because it is generally a fan issue that most people see at first. I know i have one.
