I think the special button on the keyboard is a fingerprint/lock button. Not sure if the computer supports powering on by pressing any key like the MacBooks, but it certainly will wake from sleep with any key. I don’t think you’re supposed to fully power it down as part of regular use, so they can get by with a less accessible power button
Sounds like you should buy a different thing. I bought one, though. None of this keyboard stuff matters to me, since I won’t even be using a keyboard with it
