I want to be able to close my MBP display and have an external monitor hooked up. Is it possible to do so. If so, how?

i know there is a way... but i'm pretty sure u have to dl an app for that...


i have heard that this is not reccommended because a lot of heat is transfered up through the keyboard/speaker grilles...

but possibly someone else can reinforce this issue

Search for "closed lid mode." This is built-in, in your manual, and discussed here many times. You need a monitor, external mouse, and keyboard.

From what I know there isn't a way you can do this without momentarily putting your machine to sleep. The procedure that I use is:
1) close lid (MBP goes to sleep)
2) plug in external display
3) plug in external mouse or keyboard via USB-- this step will wake the MBP back up
4) you're running in closed-lid mode

edit: The few times I've done this, heat hasn't been so much of an issue. To be honest, I prefer running with an external display and the laptop open (giving me dual displays) rather than running closed lid.

Don't forget power!

Closed lid mode will only work if your MBP is hooked up to AC power.

Yes you can do this, no it is not dangerous, it is documented by Apple and in your Manual.

I do this daily.

Plug in the Monitor, and the KB and mouse (or use bluetooth like I do). You MUST plug int he power.

You then use the keyboard to wake the MBP from sleep - or you open the lid, press the power button, and close it.

There are no heat issues, but if you are paranoid, you can press the button and leave the lid open slightly.
I free'd my mind... now it won't come back.

Black_Rain, good question, I've always just turned down my display brightness to off. Since that is about all closing the lid would do, other than look cleanly folded up.

Well, you should always put it to sleep before moving it to prevent damage to the hard drive. The sudden motion sensor will help in this regard, but I try not to move my laptops when they are awake. As for the wake time, I don't know which machine you have, but if you disable Safe Sleep, I would think that it would wake up much faster since the memory contents don't have to be retrieved from the hard drive.

So is that a 'no' to Black_Rain's original question? I want to be able to close the lid and for the computer to do nothing. Sometimes I need the computer to be portable but sleeping will stop it from completing a task I started on it. Thanks.

Edit: I mean without an external keyboard, mouse, or monitor.

I would've sworn there was a hack to enable this function, but I can't find anything about it. Safe sleep is not what I'm looking for.

I do this everyday when using the MBP at home with a Dell LCD monitor. I did not know you could power the MBP on and immedietely close the lid. I usually let it power up then close the lid, wait, hit space bar to wake it up on the external.

Well since there is
> sudo pmset lidwake 0
that got me wondering if there isn't something like
> sudo pmset lidsleep 0
But unfortunately that doesn't seem to exist.

Is there some kind of alternative command? I guess that would pretty much do the trick. Any ideas?

does anybody know if it is possible to do what Black_Rain requested? I'm interested in closing the lid of my MBP and having it do nothing (i.e. not sleep in any way). Basically have the screen shutoff and be folded nice and neat like another forumite put it. This is what I want. I'm new to Macs, but not to computers. This is a feature I use regularly on my 2 IBM/Windows laptops. Thank you for your time.
