If I hover my hand just below the arrow keys I'll get the first signal, after I take it away I get the second one. There seems to be a delay in when I put (or take away) my hand to prevent spamming the logs even more. It could be to sense lid close, but there's already another sensors for that I thought. The only remaining thing I can guess it that it's to detect your hands to turn on the keyboard backlight or something. I don't think it's related at all to the fingerprint sensor as I hover my hand to the right of it. -- Matthew Thode
