Question AORUS 17X (2023) fans start to spin full power after shutdown

Mar 4, 2023
The Displayport 1.4 cable that I was using was not a VESA certified one. The issue is that uncertified Displayport cables may have their port number 20 connected to the PWR instead of being open circuit. Since most of the cables are not VESA certified, the hardware producers were implying their own hardware or software solutions to overcome this. I've used my old cheap cable with an MSI and Razer laptop before and had no issues. Seems like Gigabyte missed something here. Here you can check the validity of certifications

I've been using this laptop for last few weeks and its good except this weird issue. I'm using it with a Samsung G5 34 inch connected via DP port and whenever I turn off my laptop, it remans silent for a while. Later suddenly fans kick in full power and does not turn off until I plug the DP port off or connect something to USB-C port. If I turn it off while its not connected to external monitor, nothing happens. I've sent a post to Gigabyte about it and they said me to contact to the seller but I'm living abroad now and unable to do it so.
Any suggestion?

so far i tried to;
-updating drivers and BIOS
-reset the battery via pin below the laptop
-disable Intel Management Engine WMI Provider from device manager
-tried hdmi connection. It works well. No issues.
