I've got my personal, elderly HP Windows PC (over ten years elderly, I'd think), and a work Dell 7420 laptop (my second - two successive employers happened to issue me the same model). I use
this PWay switch (at least, it looks like that one).
I got work to issue me with a Dell docking station. That's connected to the switch, so all I do is to throw the switch and plug in the docking station - I have to unplug it and plug it in to kick the laptop into life, since the laptop has no external power switch and it sits in a small gap with its lid permanently closed (while at home). I always power laptops down fully at the end of the day, which I know not everyone does.
Works really well. Very occasionally the laptop fails to start up, and I have to open its lid and press its power button.
