Clamshell Mode Not Working

Although I follow the instructions for Bluetooth mouse and keyboard at...
http://docs.info.apple.com/article.html?artnum=300562
...I cannot get my LCD monitor to come on when the MBP is closed.
What am I doing wrong???

I would try creating USB activity somehow. If you don't have a USB mouse or keyboard, use one of those flash memory drives and plug it into the USB port on the MBP. If that causes the MBP to wake up and the external display lights, then you have determined the problem is with the MBP being able to wake from the Bluetooth peripherals.
If, on the other hand, USB activity is not waking the MBP either, than the problem lies elsewhere. I assume that the MBP sleep light remains on when the external monitor isn't working? Is that a correct assumption, that the MBP isn't waking?

  • 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!

  • 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 not working, tried every possible way

    Grr, this is getting so frustrating. I have tried every possible method, even following apple's guides. None of them work for me. I even tried the "boot" method the guy told me about in the last thread, and that still didn't work!!!
    I have both my bluetooth mouse and keyboard hooked up right now, and it is not working . What would you guys recommend I do next?

    Just to make sure, are those the instructions you followed:
    http://support.apple.com/kb/HT3131
    If you have, do you happen to have a wired keyboard and mouse to try it with - that would rule out any possible bluetooth problems. If you haven't, try the ones in the link I posted. Also, are you using the correct cable connections/ports?

  • Mavericks clamshell mode stopped working

    I have a summer 2007 15 "MacBook Pro and since upgrading to mavericks clamshell mode doesn't work anymore. Now closing the lid doesn't do anything and the laptop screen stays on and the computer doesn't sleep. I saw a blog entry which gave a terminal code to boot with the internal screen disabled. This is not the ideal way and secondly the computer still thinks the screen in use and as a result still is producing the desktop associated with the internal display.
    I want to have not only the screen off, gets really hot otherwise, but also the os to only create one desktop such that my windows don't get scattered over desktops that aren't visible. I just really need clamshell mode to work again.
    Any thoughts?

    Finally found a fix, i reset my smc. This not only returned clamshell mode back, but returned the fan level to a more normal and less noisy level. I guess the moral of the story is never update your OS while in clamshell mode.

  • Widgets on my desktop using dev-mode not working in Lion

    I'm trying to get iStat back ontop of my desktop like I had in Snow Leopard. Dev-mode not working to bring widgets forward anymore. Any Ideas how to do this in lion? In Snow Leopard it was defaults write com.apple.sashboard devmode YES now that isn't working.

    When I connect my MBP (mid 2010) to iMac 27" (mid 2010), via Mini DisplayPorts, after pressing Command+F2, iMac screen went "blank" while MBP screen stays "blue" for few seconds and went back to normal. How to solve this problem?

  • Blue screen on start up. Safe mode not working?

    Blue screen on start up. Safe mode not working, any suggestions?

    Thank you, I had forgotten about target mode. I was able to back up all of my files. I also copied some additional 50 GB of files of the disk as a stress test and the hard drive worked fine and quick (and because it was quicker than retrieving the same files from a network drive to my desktop).
    I was hoping to also unpack the Applejack files on my desktop and put them back so I could run them in single user mode without running /etc/rc. However I haven't been able to get my Linux desktop to mount the iBook in Read-Write instead of Read-Only yet (I don't have access to another Mac at the moment).

  • Target Display Mode not working iMac 27(2012) Bootcamp to iMac 27(2013)

    Hi All,
    I recently purchased an iMac 27" 2013 which replaced my iMac 27" 2010.
    ===============
    PREVIOUS SETUP
    ===============
    (1) iMac 27" 2012 - Running Windows 8.1
    (2) iMac 27" 2010 - Running OS X Mavericks
    (1)+(2) were connected with a Mini-Display-Port cable.
    (1) was using (2) as external display while (2) was set to Target Display Mode using CMD+F2
    ==============
    CURRENT SETUP
    ==============
    (1) iMac 27" 2013 - Running Windows 8.1
    (2) iMac 27" 2012 - Running OS X Mavericks
    (1)+(2) are connected with Thunderbolt cable.
    (1) can't use (2) as external display anymore becuase CMD+F2 has no effect anymore on (2) in this scenario.
    If (1) and (2) are both running OS X all works as expected.
    I am aware about the support hint from Apple where they state TDM is not working under Bootcamp.
    And I agree, while booted into Windows Bootcamp this machine can't serve as external display. Makes sense because TDM is baked into OS X display drivers.
    Anyone had the same experience and came to a soltuion?
    Thanks,
    Martin

    "Apple has no plans to implement a client driver for Windows since there is no Thunderbolt SW stack available for Windows like there is for Display Port."
    That is a little bit funny since Gigabyte and other big companies have said that 2014 is the year that they are going to implement Thunderbolt in many motherboards.
    "GIGABYTE 7 series motherboards are the very first to offer fully certified dual onboard Thunderbolt™ ports. Capable of connecting up to 12 devices plus 3 digital displays simultaneously with breathtaking data transfer speeds that can transfer 1TB of data in only five minutes, GIGABYTE Thunderbolt™ motherboards offer the fastest connection interface on the desktop PC."
    Have you asked Apple about that? I dont understand why Apple is crippling Thunderbolt on their devices...

  • Can't get 'clamshell' mode to work with Dell 2408

    I have been trying to get my Dell 2408 working in clamshell mode without any success. I have a USB keyboard, USB mouse, power adapter and monitor via DVI plugged in. I switch the display type to mirror, close the lid, wait for it to sleep, then wake it again by pressing a key on the keyboard.
    The computer wakes, the external monitor flashes but at the incorrect resolution (1200 X 800 instead of 1920 X 1200) then goes back to sleep. This will repeat over and over again until I open the lid of the macbook. I can occasionally get the macbook to wake and display on the eternal monitor but this is very rare, and when it does I get some wired artifacts.
    What's really puzzling is that the monitor works flawlessly in extended desktop mode, and works perfectly with other non mac computers. I took the macbook to the Genius Bar, hooked it up to the apple cinema displays and i didn't get the same problem! Grrr....
    So I just don't get it, both the computer and display seemingly work fine independently from one another, work fine in extended mode, yet in clamshell mode have some fairly major issues.
    Anyone have any ideas?

    My dell 2408 arrived today and I'm having exactly the same problem.I cant get it to go into clamshell mode. I lie, I got it to go into clamshell mode once. I don't know what I did. But it certainly isn't willing to go into clamshell mode again any time soon.

  • Layout Mode not working in T-Code SQVI for some GUI

    Dear Experts,
    It has been found that the Layout mode is not working in T-code SQVI in some of our users Systems . The Layout Mode is working perfectly fine in some system though. If we select Layout mode in some system it is showing screens the same as in Basis Mode.
    The GUI version is same in both the machines and both are having the same OS.
    GUI Version : 710
    OS : XP
    Kindly suggest if any settings needs to be done in System or GUI so that all the systems get the same interface of Layout Mode as required.

  • N95 8Gb USB Data Transfer Mode not working

    I have a bizarre problem with USB Data transfer.
    a) I upgraded to the new 15.x firmware with the correct HKCSL package - 0557980
    b) I connected PC #1 in data transfer mode with no issue and copied a bunch of installers onto the mass memory and went on to install them - to the PHONE memory.
    c) Later in the day, connected PC #2 and did the same with the last few applications.
    d) Next day tried to connect PC #1 and it didn't work
    e) Thought I must have an application using the MASS storage but checked and not so - all apps on Phone memory.
    f) Went to PC #2 and tried - Data transfer mode works - no problem.
    g) Tried PC #1 again, and still not working. I get all the right messages (Mass storage cannot be used at this time etc) on the handset, and I get the "safely remove hardware" option appearing on the PC - but I don't get a drive letter assigned in the Windows Explorer.
    h) I have tried it on PC #3 and this works as well - no problem.
    1. The working PC's both have PC Suite 2-Beta installed, while the problem PC has no PC suite at all.
    2. I have downloaded the Nokia-connectivity_cable_driver_rel_6_85_10_0 and it installs properly - giving all the expected wireless... options in Device Manager, but I still don't get a drive letter assigned with the basic data transfer mode on this problem PC #1
    So the issue seems to be with a PC that has never seen any version of PC suite, but it worked straight after the firmware upgrade.
    All PC's are XP SP2.
    Any suggestions on anything else to try ?
    Regards

    SOLVED by:
    - attaching N95, selecting USB Data Transfer Mode
    - Going to Device Manager
    - Selecting the USB Mass Storage Device for N95
    - "Uninstall"
    - Remove cable when N95 says its safe to
    - Re-attach cable
    The PC then re-discovered and reloaded the drivers including the mass storage which then worked normally.
    No idea what messed it up in the first place though.

  • Adding 3 Airport Extremes to Linksys WGT4400N in Bridge Mode  Not working

    I have a network that starts in a homerun closet and is expanded across 5 acres to differnet locations via CAT5e.
    Homerun Closet has Linksys WGT4400N with Cat5e running to three different locations on property. The cables are within length limitations.
    1st Airport Extreme N Running in Bridge Mode Connected and Working in Main House
    2nd Airport Extreme N Running in Bridge Mode Connected and Working in Guest House
    3rd Airport Extreme Replaced with new one Connected and Not Working in Office. This Airport Extreme N is configured just like the others but it cannot see the network. Cables Verified with Testers and Mac Pro at office location, works when ethernet cable is directly connected to system.
    Not sure what is going on. IS there s limit to the number of Airport Extreme N's used as bridges?
    I have 2 of ther working and the last is not. First Airport Extreme N for office was bad replaced.
    Thank You

    The Netgear wireless server has control over what what devices are allowed to connect.
    Unless you tell the Netgear what devices you want to allow to connect, it will allow any wireless device to connect as long as it knows the wireless network password.
    IF.... .you were using two AirPort Extremes, and not a Netgear, the two Extremes would communicate to each other....so you would only have to enter Timed Access settings on one router and other AirPort would automatically pick those settings up.
    But, even this was not the case until the last year or so when Apple updated firmware.  A few years ago, you might have had 2 Apple AirPort Extremes on the network, but you still had to manually set up Timed Access on both devices separately.
    Bottom line, you need to setup the equivalent of Timed Access on the Netgear router.

  • Printing in TUMBLE mode not working

    hello,
    I have the problem that the TUMBLE mode does not work in my program.
    I have tested the printer with MS Word to be sure it works with my hardware and
    it succeeded.
    I use a DocPrint Object and specified the PrintRequestAttributeSet attributes OrientationRequested.LANDSCAPE and Sides.TUMBLE (=Sides.TWO_SIDED_SHORT_EDGE).
    If I change this to Sides.ONE_SIDED, the printer correctly prints each pair of sides on 2 papers (one-sided).
    If I change this to Sides.DUPLEX, the printer prints in DUPLEX mode correctly (TWO_SIDED_LONG_EDGE)
    If I change this to Sides.TUMBLE, it still prints in DUPLEX !
    If I use OrientationRequested.PORTRAIT, the printer prints always binding to the short side , like I need it (no matter if I switch to DUPLEX or TUMBLE).
    What could be the reason that the program ignores the TUMBLE attribute ?
    Here is my code:
    public static void doPrint(Print printData)  throws Exception {
                    PrintService printer = null;     
              printer = printerLookup(printerName);                         
              DocPrintJob job = printer.createPrintJob();
              DocFlavor flavor = DocFlavor.SERVICE_FORMATTED.PRINTABLE;
                    Doc doc = new SimpleDoc(printData, flavor, null);
                    PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
              aset.add(OrientationRequested.LANDSCAPE);               
              aset.add(Sides.TWO_SIDED_SHORT_EDGE);
                 job.print(doc, aset); //print
    }

    Yes, it's not a permission issue. And it only happens on this one machine too. No error messages in any of the log files. This is a real tough one. I'm tempted to think that it might be a graphics driver issue. The machine with the problem is a 2008 Mac Pro with a GeForce 8800 GT. So if anyone with a similar configuration could test it I'd at least have another hint for what's going on.
    As an interesting sidenote, other capture applications like Voila work fine, which makes the graphics driver theory unlikely, but well, I'm running out of possible causes.
    Thanks,
    Jazz

  • Airport in bridge mode not working in Windows7

    Hi everyone,
    Last night as I was browsing the web on my iPad the internet stopped working...I am using an Airport Express router plugged directly into the wall socket of my apartment which was configured by the ISP.
    I have been using this config for the past 7 months with no issues but last night it just stopped working and the yellow indicator started flashing.
    I went into Airport utility and it tells me the Double NAT problem has been found (maybe the ISP changed something?)...and they suggest to change the Airport configuration to Bridge Mode ... said and done...now the Internet works fine under OSX and on my iPad but it does not work anymore in Windows 7.
    Some of my family uses Windows 7 for some very specific apps and now it's just dead, internet does not work anymore.
    Also, in OSX / iOS I didn't make any changes, I just changed the Airport configuration to Bridge mode and it worked right off the bat.
    Has anybody else confronted such problems before ? If so, what would be the best way to fix this ?
    Thanks!

    " I tried trunk port also but it got disabled"   <----- if your L2 config is not correct, nothing will work.
    What is the setup on the switch ? Trunk or access vlan ?
    What is the status of the interface ? up ? down ?
    Do you see something in your arp table ?
