I have a new SER8: https://www.bee-link.com/en-de/products/beelink-ser8-8745hs
As described above, external drives stay on when I turn off the computer.
I have worked my way through all the settings in Windows, but that doesn’t seem to be the problem. Could it be a setting in the BIOS? Please advise. I can show pictures of the device and the system information on request.
