Hi All I have 820-3437 running too slow, tested on TG Pro, it say error Temperature : Hard Disk Sensor. Any one exactly knew the position of that sensor. or other help please. Update (03/22/2022) Replace with good know ok ssd but no luck. then change the flex cable of Touch Pad and Good Luck. It is working 100% ok.
The SSD drive has its own sensor within it. Did you try replacing it yet?
