Hi, I wasn't quite sure where to post this, but this is my issue:

I freshly installed Windows 10 and Ubuntu 19.10 shortly after for dual booting. My computer is a Lenovo ThinkPad L390 Yoga connected via USB Type C to a dock with keyboard, mouse, monitors, network etc.
If I shutdown the computer when running Ubuntu and try to start it again, the screen stays blank, it doesn't even show the BIOS logo, only the fan speeds up. If I unplug the Type C cable then, the screen suddenly turns on, asks me to open BIOS setup and continues to boot normally into GRUB. However, if shutdown the computer when running Windows, it also boots normally if connected to the dock.
