Guys, I am not a big fan of USB-C. Nevertheless, I have two laptops with USB-C that I use with the docking station and external screens. I do not need the internal screen when docked and for this reason, I like to keep the lid closed. This allows me to place the laptop of the table and have more working area on my desk. I can theoretically wake up or enable the laptop using the button found on the docking station. Unfortunately each manufacturer (HP, Lenovo, Dell) uses a different implementation for the wake-up functionality. Only the same-brand docking station enables the laptop. (HP dock enables only HPs, Lenovo dock only Thinkpads, etc.).
Does anyone know how laptop makers implement this feature? I assume that it is either a sequence, specific voltage, or the combination of both, on data signals. I am hoping that I can maybe create a small board that one puts between the dock and the laptop that enables all based on the config.
Believe or not, I am not the only one who has this problem. I've already met couple people looking for same.
Thanks for any tips.
