Clamshell mode in bootcamp not "sticking"

MBP 15'' with bootcamp.
Latest Bootcamp drivers installed
Minidisplayport-to-DVI adapter in.
I open the laptop. boot Windows, I see the image on the laptop screen AND on the external monitor. When I'm at the "ctrl-alt-del" screen I try and close the laptop to go into clamshell. No dice.
I open it again, log into windows, wait for all the systems to start, try again. Nope.
I open it once again, go to "Control Panel", then "Change what closing the lid does", I change NOTHING (the setting is already on "do nothing"), click "apply", then close the lid and voilà... clamshell mode.
It's getting on my nerves... any chance someone had the same problem?
Thank you

I had clamshell mode working under Windows 8.0 Enterprise on my 2015 MBP 13 Retina. I could close the lid while running Windows 8.0 and then wake up the MBP using the Apple Bluetooth keyboard and it would drive the two connected external HD monitors.
I've upgraded to Windows 8.1 Enterprise and the wake from sleep in clamshell mode no longer works with the Apple Bluetooth keyboard, trackpad or mouse. I've just used worryingroadworrier's suggestion and I can close the lid and the MBP now drives both the connected external HD monitors while the lid display remains off. Wake from sleep using the keyboard, etc., still doesn't work but my goal was to be able to use both external displays.
Thanks to worryingroadworrier and also thru_the_loop (on http://www.mac-forums.com/forums/running-windows-anything-else-your-mac/222848-h ow-get-clamshell-mode-windows-7-macbook-…) for their suggestions.

Clamshell mode and mouse not working on external monitor

Suddenly I notice that when I put my MBP (late model 2008, Lion) in clamshell mode, my blue tooth mouse and wireless keyboard become unresponsive
I think the MBP has frozen but its only that the mouse and keyboard do not respond.
I have to open the MBP in order for the mouse to work so I can work using the externa (Apple 24" monitor).
This just started happening.
Has anyone experienced this?
Just started happening as of yesterday March 19. I cannot think of anything new I downloaded. Rebooting did not seem to help.

Safe mode display settings not 'sticking' after restart?

Hi
I used a display setting not supported by my Mac mini and consequently had a 'out of signal' error on my monitor and restarted in safe mode, logged in and altered the settings.
When I restart the display settings do not 'stick' and I get the same error. How do I get the settings to stick? Have tried logging in as administrator and user with no joy!
Thanks Nigel

Hmm. Maybe that combination of changing resolution in Safe mode and resetting PRAM have a combined effect of some kind? Worth remembering for the future. Thanks for posting.

HT3131 Why doesn't Apple mention using the Display control panel's "Arrange" feature to move the menu from the Macbook's display to the EXTERNAL display? THAT'S the real answer to make Clamshell mode work, but it's not mentioned in any Apple documentation

After a recent OS update, Clamshell mode quit working. I couldn't find any Apple documentation
that would help. So many people were stabbing around in the dark, until I finally found the following information
that is lacking from any Apple documentation that I've been able to find.
Here's what I found to be the most helpful:
Forcing a MacBook to use the External Monitor:
I tried about everything: Rebooting, switching off completely, removing and inserting the Thunderbolt->HDMI adapter etc.
The only thing that finally worked was the following:
1. Take it out of the dock and connect to Power and HDMI to the TV.
Shut down the Mac. Turn it on and close the lid. It will now boot up on the external screen.
Log onto the Mac, and put it in sleep mode (Option-Command-Eject).
Put it back into the dock and wake it up with the spacebar.
It should be OK now... until the next update...
Note: One indication that you’re going to have extreme trouble with this is when (occasionally and without reason) the Mirroring Options icon shows up on the top icon bar.
Other useful commands:
“Command + F1” puts PC in Two-Screen MIRROR mode.
If it’s REALLY being stubborn, do the following (Clamshell Must be open
to see the arrangement tab.):
In System Preferences > Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor (Yes, I know, it’s hard to grab ahold of it...) That will make your EXTERNAL monitor your main screen.
You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV, make sure it’s asleep (Option+Command+Eject buttons) or your Menu Bar will automatically change back to the MacBook.

"Clamshell Mode" gone with 10.6.6? Or not?

Can people confirm if "clamshell mode" (using a laptop with closed lid; power, keyboard/mouse and monitor attached) still works in 10.6.6? I have seen reports that this (for me pretty important functionality) has been lost with the 10.6.6 update.

I just received my MBP 15" Core i7, bought the Henge Dock docking station and all related gear including an apple Bluetooth keyboard and trackpad and ended up also frustrated because the clamshell mode is not working... once I disconnect the laptop from the power to put in the dock, the laptop never wakes up again wither with keyuboard keystroke or magic trackpad activity... please let me know if there is any worksoround for this problem. Thanks.

Clamshell Mode Not Working With Acer V223W

I recently got an Acer V223W 22" monitor to use at the office with my MBP. Using the DVI port, it works well, but I cannot get clamshell mode to work. I close the lid, and when I awaken the computer with a mouse click, I know it wakes up because I can hear the audio, but the Acer display does not light up.
Any suggestions as to how to fix this are welcome!

HT3131 Clamshell mode not working even after powering off and reconnecting display; external monitor goes black anyway

After connecting an external monitor (non-Mac) to my MacBook (Mac OSX 10.6.6) w/proper adaptor, setting up to use clamshell mode as per manual, the external still goes black even after putting MacBook to sleep, disconnecting and reconnecting external and powering up again as suggested in Support. Displays are set to Mirror. Also, when I open Displays in System preferences, 2 different windows for Resolution settings appear. Where have I gone wrong? This monitor (Viewsonic) came with it's own software for setup on a Windows PC, but of course it is not being used on the MacBook.
Any help would be appreciated!

Hi Mike,
Yes I followed all the procedueres....except for waking the computer using a keyboard click. For obvious reasons one is just inclined to open the top of the MacBook to wake it when the external goes dark...I did that twice, until I realized that very last step was needed to 'wake' it. It worked. Something so simple, easy to overlook I guess.
I did leave the monitors mirrored, fyi, if I don't then all I can access from the external are the resolution settings. This Viewsonic comes pre-loaded with Windows software of it's own and doesn't quite behanve the way my previous external did, but I got it figured out.
Thanks for your response, tho!

Not auto detecting wifi out of clamshell mode

I have a MacBook Air and when opening my laptop out of clamshell mode my wifi will not auto detect the closest connection point. The current work around is to right click and select the appropriate connection. While this is ok, I would really like the auto detect to work properly.
I do have the automatic find selected in Network Preferences.
Looking for any solutions.
Thanks.

Unless you get that WRT54G for free or next to free, pass on it and pick up an old apple WAP off eBay or similar site. Like you my iPad has a connectivity problem with the WRVS4400N running iOS 4.2.1, where it didn't have trouble with iOS 3.2.2 and ran fine for five months.
My solution at the office was to spur a second router off my DSL router just for the iPad. The first was a WRT54G that had to be set to only one 802.11 protocol to keep the iPad reliably connected, but swapped it out for an old airport extreme that I kept on after testing it to be good. With a home network like you describe, I would run a subnet off the WRVS4400N just for iPad using an apple WAP (the configuration app for Windows is easy to use).
Good luck.

HT1338 early 2012 macbook air clamshell mode not working after mountain lion update

Can't make 2012 MBA 13" work in clamshell mode after updating to Mountain Lion. All peripheral devices are connected, as is AC power. Closing lid causes external monitor to enter sleep mode (presumably, the MBA is going to sleep as well).
Power settings are set to stay awake when on AC power.
Thank you.

Hi,
The two may be linked as there is a common support app called IMAgent that helps with both Messages and FaceTime.
Shut down both apps.
With the Finder as the Front App > use the Go Menu > Hold down ALT key and select Library.
In the Library find and open th Preferences Folder
Find com.apple.IMAgent.plist and drag it to the Trash
Before restarting the App now go to Activity Monitor in Applications/Utilities.
Find imagent (it is in lower case).
Highlight and use the Quit button.
Now restart the app(s).
This will recreate the .plist from defaults.

Clamshell mode does not work with Mountain Lion.

Installed Mountain Lion on 11" MacBook Air last Friday night. Now system does not appear to work in Clamshell mode, as it won't wake or connect to external monitor.

Apple Tech Support was very helpful. The MBA works in clamshell mode next to my monitor now -- but does not work in the Henge Dock. Henge Dock has been contacted.

Sleep not working with external screen in clamshell mode

I have my macbook with Lion operating in clamshell mode with an external display connected as the main screen.
Although I have set the computer to sleep after 10mins, this never happens and I have to sleep the computer manually every time.
If I disconnect the external display, or open my Mac and work with both screens, the computer does sleep properly after the set time.
I can't seem to find the fix anywhere, and the people in the mac store couldn't help me either.
Can anyone help please?
Thx,

How to get clamshell mode with Windows 7 on Macbook Pro?

Hi,
I am running Windows 7 on Macbook Pro using bootcamp. In OS-X, I can use this cool clamshell feature wherein after putting the MBP to sleep by closing the lid, as soon as I connect an external keyboard, mouse & monitor, I get the display on the monitor and immediately start using the keyboard & mouse too, converting the laptop instantaneously to a desktop.
I am trying to do the same thing on Windows 7, close the lid of the laptop to put it to sleep, connect my external monitor, mouse & keyboard, but however the laptop never wakes up (even after moving the mouse & pressing keys in the keyboard). I tried several things in Windows 7. Under Power Options, Disabled "selective Suspend of USB", but that did not help. Next, in the "Device Manager", for the "Root USB Hub" & "Generic USB Hub", I tried to set "Allow this device to wake up the computer", under Properties -> Power Management, but that option is grayed out. I tried to experimented with Sleep types like S1, S2, S3, but except for S3, the other two are shown as "not supported by firmware" (using powercfg option in command line). Countless hours wasted on google search to get this working with no success
I would greatly appreciate any help on this issue.
Thanks,
Sri

@mkultraviolent,
Thanks for the quick reply.
That seems to be a useful workaround, but I do not find the option mentioned in Display/ Nvidia control panel. However, I find an option in the "Power Options" which has a "Do Nothing" option in the combo box to select what "Closing the Lid" does. Is that what u are referring to?
Also, one problem in this approach is, if we do not sleep when the display is closed, that will keep the internal display (laptop's display) running in clamshell mode even after the lid is closed? (which will heat up the laptop badly).
The exact option I am looking for is, while the laptop is in sleep & lid closed state, connecting the external keyboard/mouse/monitor and pressing a key in the keyboard or moving the mouse should wake the computer from sleep. If this happens, the internal display won't be running. I am able to achieve this in OS-X.
In Windows7, I have a workaround by which I can almost achieve this result, wherein, while the laptop is in lid-closed, sleeping state, after connecting the external devices (keyboard/mouse/monitor), I open the laptop's lid for a fraction of second, quickly move my finger over the touchpad & close the lid again. This wakes up the laptop, & while it is waking up, Windows realizes that the lid is closed and that external devices are connected and gets into clamshell mode (I have verified that in this state, the internal display is not running).
This workaround was fine so far, but I got this hengedocks docking station for my macbook, and I am no longer able to use the workaround, because, after plugging my macbook into the docking station, I cannot open the lid. So, the only option is to make Windows7 realize that external devices are connected & wake up on external keyboard stimuli (Hence the question).
If my question is not clear, this video kind of explains what I want to achieve:

Clamshell mode w/external monitor broken in 10.8.2

Ever since I made the .2 upgrade in mountain lion clamshell mode does not work with my MBPro 8,2. Previously in Lion and Mountain Lion clamshell mode worked fine, I even executed the following terminal command so I could open the lid without the internal display turning on (sudo nvram -d boot-args). Now when I wake the computer from sleep with the lid closed, mouse and external monitor plugged in, I get to the login screen, the desktop will flash and then it will go back to sleep again. The only rememdy is to open the lid, but then my terminal command isn't working and the internal display turns on. This is most frustrating. Any help is appreciated.
Curt

Thanks for the snarky reply. I know how to do a search, you'd assume if I'm smart enough to try a terminal hack I knew how to use a web page search box.
It looks like every discussion on the clamshell issue gets mysterious "closed," "helped" or "answered" when indeed there is no real solution, including the thread you linked, hence my new topic. So I appreciate the help. </sarcasm>
This is a real problem and I wish I could be shocked at Apple's response. I use Win7 in bootcamp for work, it is so trivial to turn off my internal laptop display or work in clamshell mode. In the rush to get out Facebook integration and shared photo streams Apple really let this bug through in the update?
Back to my issue, it doesn't matter what monitor port I use (VGA or DVI) clamshell mode doesn't work. Turning off the internal display obviously doesn't work when connected to an external monitor. Contrary to your link (and many other threads) this problem (clamshell mode or turning off the internal display when an external is attached) still exists. It worked in 10.8.1, it doesn't in 10.8.2.

Macbook Pro 2011 clamshell mode broken by latest software update?

After installing the latest MacBook Pro software update and EFI update through Software Update in the evening May 4, I am unable to enter clamshell mode any more. It used to work before. After waking up in the clamshell mode, the machine promptly goes back to sleep. On subsequent attempts to wake up the system, the laptop itself appears to wake up (at least the sleep light stops blinking) but the display does not even wake up. I can still work with external dsisplay with the lid open but this is highly annoying. I have reset the PRAM with no effect. The machine is a 2011 MBP, 15" inch, 2.2 GHz quad i7. Keyboard and mouse are wireless Microsoft desktop but the problem is also present with wired peripherals.
Does anyone else see this problem after installing the latest patch?

Okay, I'll add my frustration here as well.
I've had this problem too, and more noticable since the 1.4 update.
I posted a thread similar to this here.
But I'll just copy over what my main problem was...
Whenever I plug my computer into my Cinema Display (with the computer closed) it won't wake up fully. The status light will come on, any external hard drives will spin up, but the display won't turn on and the computer will go back to sleep.
I have to restart the computer manually to get it to work normally, and if I disconnect it while it's between the sleep and wake mode and try to open it, the backlight will come on but the screen will remain black, causing me to have to force restart it.
This is in addition to my first problem with the backlit keyboard not coming on automatically after sleep, which was temporarily fixed by resetting the SMC, but it goes back to the problem after a week or so.
What could be causing either of these problems? Could it have something to do with BootCamp since I have it installed, or is there a defect?
I would bring it back to Apple, but there's a small dent in the front right corner, and I'm afraid they would deny any problem I have.
I took my MacBook Pro (2011, i7 2.2, 17") into the Apple Store on Monday, and after about an hour of attempting to replicate the problem with a different monitor, there was only one time where there was any sort of problem.
The employee told me to see if there will be a fix, or otherwise they will replace the logic board for me.
One thing I'd like to add as a note...
It seems that the problem is more prominent when I have my computer with everything on it as usual. As in, before I took it to the Apple Store I performed a clean install of OS X, and that may be related to how bad the problem is, any opinions?
I had attempted at reinstalling OS X from a Time Machine Backup, but the problems continued shortly after completetion. In addition to this, I clean installed OS X, and manually reloaded my applications and media, hoping that the problem had stemmed from some kind of broken file system that could be repaired by a new install.
But no matter how I do it, the problem comes back despite the method. It is really something I want fixed, as I pretty much only use it in clamshell mode when home...
