Description

I have a StarBook MK V with Coreboot connected to a Dell S2719DC external monitor that supplies 45 W of power over USB-C. However, the laptop draws more than the available 45W of power and the display shuts down with a warning message: "Excessive Power Draw from connected device".

I understand that this power management feature could be handled in Coreboot. Is this a feature that could be supported in Coreboot in the future? Is there something that I could do to support the development of this feature? Is there a workaround in the meantime?

Thanks!
