I just want to know what I can do. What happens if I change the registry?
Mine is very loud, with the noise continuous. No one can hear me when I try to use the mike. It is very loud and continues nonstop.
Does changing the registry shut down the fan? Is there any risk? I cannot use it because it is so loud it interferes with my other computer on Zoom and creates an unbearable drone in the background while I am using another computer next to it.
I am so surprised that Microsoft has not responded to any of our complaints with any solution.
The registry entry just changes the way power is managed. It doesn't affect fan speed or anything like that, those are based on component temperatures or other advanced settings for power users. In some computers, you can actually set min/max processor usage percentages in the advanced power management settings (built into Windows). The Surface hides it for whatever reason, but gaming machines show it there because it is useful performance-wise to not let the processor idle. Of course I can't promise no harm will come from it, but it's unlikely. It still is a work-around that customers shouldn't have to do for this price-range of a laptop.
If your surface is running the fan high speed at all times, something else is probably causing that. It could be another actual defect. When the buzzing starts, the fan shouldn't be going much at all (if any) because the CPU is idle and not generating high temps. It could start going faster if you do some CPU/video intensive stuff, with the buzzing still persisting after it first happens, though.
I did tests on all of that when trying to give tech support more details when these laptops first came out. Thinking back though, I'm pretty sure they were already aware of the problem and just going through the "script" to get me to shut up and ask for a replacement.
