Clearing the CMOS is not drastic at all imo, you can save then restore a profile in seconds. I tried the power removal and it didn't fix it, same as for others too, only a CMOS fixed it. I have repeated this two times now.Sure, but I haven't seen anyone removing power to fix the issue. Or trigger the issue by connecting a different cable.
Clearing the CMOS is a bit drastic IMO so it would be good if others experiencing the problem can simply remove power to get around it....?
Anyway,
I am interested to know if your switch still detects a link when windows is shutdown?
I will let you know about the light next time I shutdown (im usually in sleep mode).
