Power on with lid closed?

Hi all,
I'm thinking about buying a MacBook. I would like to attach it to my external display while using it at home. For that I would find it extremely helpful if I can turn it on without opening the display-lid.
Is it possible to turn the MacBook on by (for example) a USB Keyboard?
Thanks in advance
Henry

Im not really sure if its possible to keep it awake with the screen closed. I guess in theory you could close it to make it sleep, then via USB keyboard/mouse wake it up when the screen is closed but I have never tested that functionality. You can close it 90% of the way then drop the brightness down to 0 so the backlight turns off. I think its actually bad for the laptop to keep it shut, as heat does come up from the keyboard (heat rises obviously) and I have noticed that with PC Laptops, when you close the display and keep it running, inside the display/keyboard it gets insanely hot as the heat cannot escape from the top.
As far as turning it on via keyboard, you can wake it up, but I think the USB ports are disabled when the system is off, thus cannot power the system up. Also, note that the Macbook has no docking port, the docs available are fairly expensive that mimic normal PC docs.

Thunderbolt display problems using MBP with lid closed

I am experiencing a very reproducible problem since purchasing aThunderbolt display to use with a recent (1 month old) Macbook Pro 13"2.7GHz i7.
I use my MBP with lid closed with myThunderbolt display. If Ithen allow the MBP to sleep and power down, on restarting it the WiFi hasstopped working- the menu bar says I am connected by WiFi but Safari will notconnect to the internet and Time Machine cannot connect to the Airport/TimeCapsule to backup. Nothing I do will fix it (shutting down all programs, turingWiFi off then on) and so I have to shutdown/reboot BUT THEN the MBP freezesduring shutdown (waiting 15, 20, 30 minutes!) and I have to hold down the powerbutton (hard reboot). Once I reboot everything works fine UNTIL I take a breakand the computer goes to sleep again.
Doesn't seem to be a problem with the MBP lid open, but I needto test this a bit more to be sure...
On top of this the Bluetooth trackpad now keeps going on andoff; connected, not connected despite being near or the computer. Veryirritating at best, unusable at worst. This only started to be a major problem(every 10-15 minutes or so) when I started to use the Thunderbolt display.
These problems seems to be in some ways similar to anotherthread:
https://discussions.apple.com/message/16205098#16205098
("Major problemswith Thunderbolt display & MBAir")
I have applied the recent Thunderbolt Firmware update, and SMC& PRAM/NVRAM resets. Interestingly these seemed to work initially but thenafter a prolonged power-down period the problem has recurred. Back to square 1.
Any ideas out there?

Just to be clear, have you installed everything that you find on this page?
http://support.apple.com/kb/HT4644
I just talked to Apple Care about Thunderbolt issues in general and even though I already had the Thunderbolt Software Update installed, he had me reinstall it. If you go to this page:
https://discussions.apple.com/message/16889000#16889000
you can read in detail about the issues I was having which have for the most part been remedied (for now at least!)
The Thunderbolt cable definitely transfers heat for some reason even when there isn't a high CPU utilization. The process 'kernel_task' seems to be where the API for thunderbolt is running. But for some reason, the behavior of CPU Utilization to Fan Speed is amplified when connected to the TBD.
Apple Care is researching it.

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.

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.

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

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.

Can iTunes play with lid closed?

I am a newbie, so please excuse me if this sounds like a dumb question. I just moved from Windows world (after using it for 25 years) to MacBook Pro about 4 months ago.
I am using AiportExpress to stream music from iTunes to 3 different audio system throught my home. I would like play iTunes to play the music even when my MacBook lid is closed. I can't seem to get this work. Seems like such a basic function. Is it possible to play iTunes with lid closed? What am I missing?

{quote:title=Chris CA wrote:}If Apple were to allow it with a setting and the user burned up the computer, then it would have to be covered under warranty, which it isn't.{quote}
Don't mean to argue.. but I still believe that it should be a user enabled/disabled function. I've used it on all my PCs for several years (when playing CD on Windows Media Player) and I am yet to BURN a single device
If I have to keep the MacBook open to keep running iTunes, wouldn't I run the same risk of BURNING (like you said)?
OK.. this is what I need to do...
I have all my music in iTunes. I have setup 3 AirportExpress (AirTunes) hooked up to receivers on 3 levels on my home. I'd like to play the music from iTunes (wirelessly streaming throughout the house via AirTunes) without having to keep the MacBook open. How do I do it?
I don't want to see any third party apps (e.g. Insomnia) to prevent my computer from going to sleep. I just want to accomplish what I described above. Can this be done or not?
Another question is if the iTunes is running on one of my Windows-based laptops, and I close the lid on that, iTunes (on PC) should continue to run. Right?
Any help is greatly appreciated.

Odd behavior: empty optical drive makes eject sound with lid closed

Anyone heard of this? I've got a black MacBook (2.0Ghz) w/ Leopard. Laptop is plugged into outlet with lid closed & no disk in the optical drive. Every 2 minutes or so I can hear the eject sound like when you push the eject button.
Any clues or suggestions?

I have had this problem for a couple of months. I took it into to be looked at by someone at the Apple store and they couldn't replicate the problem. It happens continuously now and drives me crazy. I took a video of it and posted it on youtube. Take a look and tell me if this is what you are experiencing, or if you have any ideas on what is happening or how to stop it. I plan on taking it to the Apple store this weekend if it is still doing this (which I am sure it is)

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

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

How to work on external monitor with lid closed?

I have an external monitor connected to my MB Pro and would like to work with the lid closed. When I shut it, the monitor also goes to sleep. Yesterday I did something right and the monitor woke but I was able to keep the computer closed. Today it's not working. I use a wireless keyboard that also goes to sleep when the lid closes.
What's the procedure to keep the monitor awake while the laptop is closed?
System 10.6.8

Yes, I have done that and tried it over and over and it still won't work. The monitor went on for a few seconds and then went black again.
Is it possible to do this with a wireless keyboard? I do press the power key to try to wake to keyboard but nothing happens.

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.

Using MBA connected to iMac with lid closed

Just purchased my 11" MBA and its working a great replacement for my 15" MBP, especially for travel.
One thing I haven't been able to do yet though is work with the MBA closed while connected to my iMac (like using an external Studio Display). I do this all the time with the MBP. I can plug it in (power and mini-display) keep the lid closed, and wake it with my BT keyboard an mouse.
Unfortunately, the MBA is not waking with the keyboard or mouse.
Any ideas? Is anyone else using their MBA like this?

Performed an SMC reset and it works like a charm.
This 11" MBA is a great replacement for my old 15" MBP. Runs on the 27" iMac fantastic (although no sound is coming through).
