I noticed that the GTR6 can be brick if you do some invalid BIOS settings change. The symtoms is:
+ After change BIOS setting, the PC does not boot anymore. No POST at all.
+ Numlock keyboard cannot turn on.
+ Fan works.
+ Clear CMOS or even remove CMOS battery does not help
SO you did soft brick to your PC.
If many people got this problem, I will write a detail post to help you recover the PC. I brick it nearly everyday to test P-state settings (has not been successful yet and BEELINK support has not helped me to explain how to make the P-State work)!
WARNING: THIS TASK REQUIRES ALOT OF PATIENT & NOT FOR NEWBIE.
I have the same symptoms (fan works, but no HDMI and no USB). I already contacted support, but did not get an answer yet. I also tried to disconnect the CMOS battery, wait a few minutes, but it still does not work. Seems related to this issue: https://forum.bee-link.com/forum ... 6064&extra=page%3D1
