The caps lock button does not respond, no.

Holding down the power button for 5 seconds has no audible or visible
effects, but does indeed properly shut it down. Closing or opening the
lid afterwards does not cause a phantom power-up.
A short push of the power button seems to start the machine up normally
(from a cold boot; just like when the lid is closed/opened after a linux
"shutdown").
