https://bugzilla.kernel.org/show_bug.cgi?id=216822 --- Comment #5 from Jacob Moroni (mail@xxxxxxxxxxxxxx) --- I should add that in my case, I’m using this add-in card in a system that has no BIOS support for Thunderbolt. The motherboard doesn’t have a Thunderbolt header, so I am pulling pin 1 of the 5 pin connector up to 3.3V to force the card to turn on, which I’m guessing is the equivalent of writing 1 to /sys/bus/wmi/devices/86CCFD48-205E-4A77-9C48-2021CBEDE341/force_power on a system with real support for this card. -- You may reply to this email to add a comment.
