    I can`t find a solution to this, i just did a clean install leopard today and now my macbook pro display does not go to sleep mode when i output it to external monitor. I do not encounter this problem previously in tiger OS. The following steps below is what i do normally to get my macbook display to sleep...

    1. close the lid, macbook go to sleep
    2. wake up using external keyboard
    3. now the external display is active while macbook display remain in sleep mode

    i could not achieve the third step now, anyone facing the same problem ???
    it is very distracting to have an extra display next to my monitor.

    Hmm. I think something's wrong somewhere, because I use my MacBook Pro in lid-closed mode with an external monitor, keyboard and mouse all the time. Do you have it connected to power when you do this? I know the machine won't wake up with the lid closed and peripherals connected unless you're on power at the time.

    yes my mac book is connected to the power when i did this. i want to do exactly as what you did.. however now macbook will go back to sleep mode whenever i wake it up for a split second, it will keep repeating.

    by the way are you using tiger os now, because i never have this problem when i was on tiger os.

    This is not a new problem. I have the same problem. I've seen countless numbers of people in this forum state that the issue is related to the Leopard Graphics Update from February that came after the Leopard system update.

    Case in point:

    I bought my MBP before the graphics update was released, and had no problem connecting to my external monitor, putting it to sleep, closing the laptop, and activating it with the wireless keyboard or wired mouse.

    Then, after the update, it will not work. I have to keep the MBP open and plugged in the external, switch the dock to the external display, and dim the laptop screen (if I don't want two displays).

    I have read here that people submitted this to Apple and that a fix is coming at some point. Does anyone know about this?

    Moving Dock to External Display.

    I have the same problem with Leopard that you guys have. One of you mentioned moving the dock to the external display. How is that done? Also, is there a way to fix it so that applications like photoshop open on my 30" and not my 15" macbook pro?

    Never mind. I found a posting which told me how to do it. Thanks anyway and I hope for all our sakes that Mac hurries up with that fix.
