Stay "awake" with lid closed and no ext. display?

I am using my MacBook Pro to stream audio from an internet radio site. The computer's audio output is wired into my home stereo system. It all works great but is there a way I can close the lid without the computer going to sleep ? There is no external keyboard, mouse or display connected.
Thanx

That's one of the cool things... the display sleeps "normally" but the computer does not. I've been monitoring it for the last couple of hours and it's not even getting close to hot. Thanx for the heads up tho...

Is there anyway to have an 11 inch mac air connected to an external monitor with lid closed and still be able to see content. I have a wireless ketboard and mouse and have tried everything. Only works when plugged in.

You are referring to a feature called Clamshell Mode, please read Clamshell Mode setup for instructions.
BTW when posting when you use generalities such as "have tried everything" this tells us nothing. When posting please be specific and try to paint a complete picture. It just makes things easier for those trying to help you.

Running MBP 15 with lid closed and external screen = damaging screen?

I connected an external screen to my laptop with the lid closed and woke it up through my external keyboard. I am vaguely remembering reports stating that heat is vented through the keyboard as well as through the vents in the back.
Does that mean that running the laptop with the lid closed is damaging the machine or specifically the screen?

No, it's fine.

MBP keeps waking up (for a few seconds) with lid closed and in sleep.

My macbook pro, with the lid closed and hence in sleep, will periodically turn on. As in, ill be laying in bed trying to sleep, ill hear the sound of the fans and hd etc turn on, and then ill see the lcd light up.. itll do this for 4 secs, then go back to sleep. Every 20 mins or so it will do this.
What the hells wrong with it ?

Do you have any USB devices attached? Any Bluetooth devices tethered and nearby? Both of those can wake the MBP... Bluetooth can be set not to wake (System Preferences > Bluetooth), but for USB the only way is to unplug them before you close the lid. If you have Ethernet connected, uncheck the box to wake for ethernet administrator access in System Preferences > Energy Saver > Options tab (in Power adapter settings) .
Hope this helps...

How to keep unplugged macbook awake with lid closed

My macbook would stay awake while its plugged in with its lid closed, but it won't stay awake once its unplugged.
any suggestions?
thx!

Requirements for closed display mode:
Power adapter
External keyboard, mouse, or trackpad
External display
If any of these conditions are missing, then the closed MBA will sleep. So, unplugging the power will sleep the system.

OS deployment to laptops with lids closed and battery power?

I'm trying to deploy Windows 7 to laptops with the lids closed. I send wake on lan to start the deployment and it works on some of the laptops (they are all identical) and the rest run part way and never complete until I walk to the laptop and open
the lid (then the deployment resumes).
I am assuming the reason some complete and some do not is because the smart device that charges these laptops charges the laptops in banks to avoid overloading the power source and maybe the laptops do not want to continue after a reboot if they are not
actively charging at that moment and the lid is closed.
Are there any special settings (power plan settings or BIOS settings) we should configure to ensure that deployment continues unattended whether the lid is open or closed and whether the laptop is charging or not?

Connect an external monitor up to one of the laptops in question to see what is really going on. Specifically what is blocking things here? Are the machines actually booted into WinPE or the full OS, or are they blocked at BIOS.
Everything else at this point is speculation. There is nothing built into MDT Litetouch that would prevent it from continuing due to the state of the Laptop LID

MBP Randomly Wakes Up With Lid Closed

Hi,
My Macbook Pro (OS 10.4.11) always randomly wakes up by itself after I closed the display lid. Is there anything I can do to remedy this? Thanks.

I get this too and it is really really annoying. Then, when I open the lid to try to put it to sleep again, it goes to sleep, so now it's doing the opposite: asleep with lid open and awake with lid closed. The real problem is that I can't wake it up! The other annoying thing is that with the lid closed some of my bluetooth devices i.e. wireless keyboard and mouse wake it up. Solutions?

Play CD music with lid closed

Is it possible to play CD with lid closed without a external display plugged in? Assuming the MBP is connected to AC outlet, and Bluetooth mouse is present.

No. You need an external display, mouse, and keyboard connected.
And why would you wanna do that? Are you running a line out? If not and you are playing the sound out through the MBP speakers, the lid would make minimize the output of the speakers and it would sound like garbage.

Any way I can play music on 15" rMBP with lid closed?

Hi everyone,
I'm enquiring if I can play music on my 15" retina Macbook Pro while it is asleep. I have an iPhone 5 I can listen to music on, but I've recently found that the sound is so much better if I plug my headphones into my Mac as it gives a fuller richer sound.

Welcome to the Apple Support Communities
You have to use an app which disables sleep when you close the lid. For this, use InsomniaX > http://www.macupdate.com/app/mac/22211/insomniax After disabling sleep with lid closed, you should be able to listen to music. Be careful doing this because your computer may get overheated if you keep the Mac with lid closed and turned on for a very long time

How to keep the MB powered on with Lid closed

How to keep the MB powered on with Lid closed and no monitor connected?

You can't. And you shouldn't due to heating issues.
There are however 'hacks' that allow you to bypass
this.

This may be true of overheating, but ONLY in the iBooks and very old laptops, if you think about it what is the difference between native clamshell mode (Using the monitor/keyboard etc) and the hacked clamshell mode? does plugging a screen in to the laptop some how create more ventilation :S
This rumor is really really wrong, and as stated only affected the old machines which were not capable of native clamshell mode, but of course we keep the warnings there because we dont want to be sued if some idiot places it in there laptop bag while rendering a movie.
PS. If anyone can give me evidence to prove otherwise i will add it to the investigation that im slowly compiling to "bust" this annoying myth

Sleep/Awake normal with lid closed.

Can I get my 15" MacBook Pro (Late 2007) running 10.7.5 to stay awake with the lid closed, yet sleep after 2 hours just like if it were open or connected to a remote display-keyboard-mouse?
I've tried the two third party softwares Insomnia and No Sleep. Each of these will allow me to close the lid and access the computer through Apple's Remote Desktop, however they never let the computer sleep. I'd like it to go to sleep after a few hours (again just like it would if the lid were open or if it were connected to external KVM.)
Any suggestions?
Thanks,

MacBook Pro won't stay awake with external display AND power connected

I've been using my MacBook Pro with an external 23" Apple display for several months, always with the lid closed and with no problems. Suddenly, I can no longer keep the MacBook awake when its lid is closed. *The AC power IS connected.* I plug in the display, close the lid, wake the system with my external keyboard, but then it will quickly go to sleep again after a few seconds. No matter what I've tried I get the same behavior.
Perhaps coincidence, perhaps not, I installed the Leopard graphics update a few weeks ago. Could this be a cause?

Apple did actually acknowledge this as a known issue with people running 10.5.2 with the graphics update, and are investigating it. There's some further discussion at this thread:
http://discussions.apple.com/thread.jspa?threadID=1394449&tstart=0
Anyway, what worked for me was powering down, connecting my external display, keyboard, etc., powering up, and immediately closing the lid. It seems to behave better now, though I haven't rebooted since, although I have switched back and forth between running with the external display, and running without it, without any problems.

Macbook sleep wake up with lid closed

Hi everybody. Since 10.9 I had a strange issue with sleep on my MBP 15. If I put it in sleep with the button and I close the lid, it will wake up closed waiting for the password.
Also, if it is in sleep while charging, or charged, and I plug off the magsafe, it will wake up again....even with lid closed.
Already resetted PRAM, SMC, all the basics, any idea?
Thnx in advance

Audio & video via HDMI to an external monitor with lid closed.

I would like to run a Macbook Pro Retina (2014) with the lid closed and all video and audio via HDMI routed to an external monitor (Samsung Syncmaster from 2010). Is this possible? When I try this, no sound is transferred to the external monitor and I cannot operate the Macbook Pro with the lid closed. As soon as I close the lid, it cuts the signal to the external screen.
I’ve tried looking for previous posts but they’re about MCP’s connecting via Thunderbolt or DVI. Any ideas?

Seems like there may be two separate questions here. Audio working in either configuration and video from HDMI when lid closed. First, you are doing this with the Mac running off of AC, not battery, right?
Audio:
Is the HCMI cable you are using able to carry the audio? Some cables don't.
The only way I've ever used external displays with lid closed is with the thunder port (or DVI) adapter, not with the HDMI. I see the specs from Apple:
HDMI video output
Support for 1080p resolution at up to 60Hz
Support for 3840-by-2160 resolution at 30Hz
Support for 4096-by-2160 resolution at 24Hz
So have you tried varying the screen res to determine the results? I can find no specs regarding what ports remain operational in clamshell. Like you, I would have assumed all of them.
I suspect only the thunderbolt port would support your desired config -- try a thunderbolt/hdmi adapter.
Finally, clamshell mode doesn't allow the MBP to cool efficiently. Heat kills electronics, so if it's too warm or the fans really kick in, you might want to reconsider this setup.

Touchscreen is tapping with lid closed (tm2 1010ea)

I often use my 1010ea with the lid closed and connected to external keyboard and mouse.
I have had to set up the touchpad so that it's disabled when external devices are plugged in (unfortunately this seems to include the touchscreen!)
Whenever the lid is closed, I get intermittent taps on the screen, so if I leave the computer viewing a webpage, I can sometimes come back and find that it's clicked on random links. Any way to get it to shut off when the lid is closed? I know on linux the hp-wmi can detect tablet mode (closed but screen up) but windows doesn't seem deactivate touch on closure.

I had an Acer tablet before my current HP that had this problem. It was probably about 6- or 7-years old before it started to do this. It was out of warranty, so the only help I got was through message boards. The best explanation I got was it was leaking electrical signals that the screen would pick up as taps. I never did find a solution to fix it and it led me to buy the HP.
Hopefully yours is still under warranty.
