What does the power button on the Apple Wireless Keyboard do? When it is paired to a MacBook in clamshell mode, does pushing the power button put the MacBook to sleep, wake it up, or have some other effect? Is the power button strictly limited to turning on and off the keyboard itself?

The power button only powers ON/OFF the keyboard, it doesn’t power off the computer.

To power off your computer using the keyboard, you might want to use any of the following:

Reference:

  • ⌘ (Command key) - On some Apple keyboards, this key also has an Apple logo ()
  • ⌃ (Control key)
  • ⌥ (Option key) - "Alt" may also appear on this key
  • ⏏ (Eject)
  • ⇧ (Shift)

⌃ Control + ⏏ Eject : Show shutdown dialog

⌥ Option + ⌘ Command + ⏏ Eject : Put the computer to sleep

⌃ Control + ⌘ Command + ⏏ Eject : Quit all applications (after giving you a chance to save changes to open documents), then restart the computer.

⌃ Control + ⌥ Option + ⌘ Command + ⏏ Eject : Quit all applications (after giving you a chance to save changes to open documents), then shut down the computer.

⇧ Shift + ⌃ Control + ⏏ Eject : Sleep the display, but not the computer. (thanks to VxJasonxV)

One more helpful one: Shift + Control + Eject = sleep display, NOT computer. I use that as a Windows + L (lock screen) equivalent in Mac. –  Jason Salaz Dec 3 '10 at 23:14
    
@Vxj thanks, added the info :) –  Martín Marconcini Dec 4 '10 at 3:55

@Josh those sure took some time! I believe I’m gonna put a feature request for a toolbar :) –  Martín Marconcini Dec 10 '10 at 21:30

@Josh I’m honored :) You can always google for these, but at least we have them here. Surprisingly, they look “bad” on Safari. We’ll have to talk with Jeff… –  Martín Marconcini Dec 11 '10 at 14:27

Yep. The wireless keyboard software detects inactivity and will go in sleep mode where it reduces power consumption, however it's probably better to turn it off if you know you won't be using it for a while. You must press that button for a few seconds. The light will show, then it will disappear while you are still holding the button. Then you know it is off.

When you turn it off that way it should display a notification on the OS X desktop, that the bluetooth device was turned off.

I'm not using one anymore. When I did, I would often forget to switch off the keyboard.

Now that I think of it it would be nice if there was an option for the computer to tell the keyboard to power off. That way when you shut down your Mac it would power off. I don't remember seeing such an option :(
