    I was seamlessly able to use my cinema display when the lid was closed before. Now when the lid is closed and it wakes up, it goes back to sleep. After pressing F7 twice I get my MacBook Pro display back up but at full brightness and can't bring it back down. I tried the PRAM reset and the one where you remove all power, repaired the disk and repair all the permissions. Sometimes it will work but after a reboot it's not working anymore. Help.

    seems like the display bug, i assume you are using 10.5.2 with the graphics update?

    i never found a fix, (to make it work with the lid closed) but mine works right now after reinstalling OS X

    So, this is impossible?

    I was using my MacBook with my 22" Acer LCD last night with the lid closed. Today, I tried waking the computer by using the keyboard (I have a refurbished previous-gen BT keyboard and a VX Nano RF mouse) to no avail. I had to lift the MB lid to get anything on my 22" screen.

    I'm a little nervous about reinstalling Leopard...

    Excuse me for chiming in, but how exactly did you do that? I've always wanted to use an external monitor and keyboard/mouse with my MBP lid closed and its own display turned off. Would you mind listing the steps? I am still running Tiger (because ProTools isn't certified with Leopard yet) and I have a 15" MBP Core Duo (late 2006 model) if it matters.

    Insomnia X. Will let you still run your MBP with the lid closed whether you have an external display connected or not.

    Handy feature. Just remember that a lot of the heat is dispatched through the keyboard, and closing the lid will mean the MBP will run hotter than usual.
