My dock (Anker 577 Thunderbolt Docking Station) worked perfectly with my 11st gen, including power on from the dock. The only thing needed was just to enable “Power up when AC power is connected” on the BIOS.
After the motherboard was replaced with the new model, this no longer works (of course I’ve enabled the same thing).
I don’t expect this to be specific to my dock but rather, a bug in the framework firmware, but in any case - anyone with a different experience with a different dock?
As far as I know, there is no common protocol for TB-Dock power buttons.
Thats very unfortunate and creates a situation, where usually the power button on a dock only works for a specific brand (e.g. Lenovo Dock => Lenovo Notebooks, Dell Dock => Dell Notebooks…).
I guess your Anker dock is exploiting the “Wake on AC” feature by simulating a power cycle when pressing the button. Very clever.
Have you tested if the “Wake on AC power” feature is working in general by manually plugging in power while the framework is shutdown?
Makes sense, so it’s a power switch not just a push button.
Have you tested if the notebooks turns on when plugging in the charger?
(Maybe the wake feature is broken in general and not related to TB/docking)
To clarify what I meant:
Dell/Lenovo/HP… docks do have a push button which behaves the same as the power button on the notebook (e.g. short press => power on, long press => force off) - those are using a proprietary protocol.
When using the dock with a notebook of a different brand, the button does nothing.
My 12th gen wakes up from plugging in a power supply, just like expected. And of course the power button on my Dell dock does not work (the power LED that mirrors the power LED of Dell devices also does not work), but that was absolutely expected.
Since a power button on TB docks is not standardized at all, you probably first need to figure out what that Anker dock does with that button press. Then one can maybe troubleshoot how the 12th gen differs from the 11th gen and maybe is missing specific functionality. Wake up from plugging in a power supply seems to work reliably though, so Anker probably is doing something else…
Also curious that the newest Anker dock (777) seems to have dropped the power button. Maybe they discovered that it does not reliably work.
@Carlos_Fernandez_San I also have the Anker 577 working with a 11th-gen, and now with the 12th-gen I cannot get it to work at all.
How is it for you, are you able to connect USB devices to the dock and have them communicate with the laptop?
On my side, no I cannot (I was able to, with the 11th-gen).
