Acer laptop AC detection

That is not my post but, it seems, everyone with this laptop is having 
the same issue.

I have an Acer Predator Helios 500 PH517-61-R0GX laptop and my AC 
adapter keeps showing as off-line. Because of this my whole machine 
throttles down like it is running on battery. I can change the CPU 
governor to "performance" which forces the CPU to normal speeds but I 
cannot keep the GPU (AMDGPU Vega 56) running at an acceptable speed.

How can I help get this fixed? I don't even see ACPI events when I 
unplug the power cord.

Is there information I can provide you for your next patch to allow 
upower to correctly identify this AC adapter?

Is there a way to manually toggle the AC online setting?

Is there a way to make a false AC device to trick upower into thinking 
the power is plugged in?


Thank you
