IChat and Closed-Lid Mode

I found something very interesting in iChat 4.0.8 and Leopard 10.5.7. I run my MBP in closed-lid mode with an external Apple Cinema Display. When in iChat, I cannot do audio chats at all - i.e. no sound input with either of my external interfaces (Apogee Duet via FireWire and Mbox 2 Mini via USB). Of course video doesn't work at all, as the built-in iSight is not accessible. If I open the MBP display, they both work normally. As soon as I close the display, wake the MBP and run in closed-lid mode, I cannot get any input whatsoever. The devices work normally in QuickTime Player Pro, Soundtrack Pro, Logic Pro, Pro Tools, etc. In either mode there IS an input level in System Preferences > Sound as well. I even tried to "trick" the system by using Audio Hijack Pro and Soundflower, but the issue remains. No combo of settings in the Sound preference pane and iChat preferences will allow a signal input.
Anyone else running a MacBook or MacBook Pro in closed-lid mode? Does this issue happen on your Mac as well?
VERY strange,

Well...Snow Leopard seems to have fixed this issue.

  • MacBooks and closed lid mode

    Has Apple changed the OS yet for the MacBook so one can keep it operating when the lid is closed?
    For a machine that costs three times as much as your typical MS Windows laptop, this seems to be an expensive annoyance.
    I've read older posts of same topic where people don't understand why one would want to do this.
    There's times when I want to keep a program running, such as downloading Apple's frequent updates and walk away for awhile, but I don't want everyone else knowing my business.
    Another related feature is locking the computer (disabling input/output), while it keeps running whatever applications have started.  If MacBooks do so, I haven't found it yet.  Everytime I put it to sleep or logout, it shutdowns all running applications, and I have to start all over when I log back in or wake it up. 
    Doesn't seem like Macs were intended for productivity.

    Mac notebooks are designed to go to sleep when they are closed. This is a safety precaution to prevent users from putting a running MBP into a closed case or backpack where it will overheat and cook itself (and possibly cause a fire) in the absence of air movement.
    You can defeat this precaution by installing third-party software such as InsomiaX that prevents the machine from sleeping, if you are confident you'll never make the above-described mistake.
    When no one is logged into your computer, no one is allowed to use it, and no programs can run. If you want to run something on it, log in. That's what logging in is for.
    When it's asleep, it is not operating. Sleep is an energy-saving mode. You can't save energy while the machine is running, so the machine can't sleep and run at the same time.

  • MacBook Pro keeps going to sleep in closed-lid mode and external monitor

    I am trying to run the MacBook in closed lid mode with an external monitor. It seems to work fine at first, but after about 10 seconds, it goes to sleep. I can wake it back up but it just goes to sleep again.
    Has anyone seen this before?

    I figured it out. Apparently you can't run in closed-lid mode on battery. I plugged in the power adapter and it's working fine now.

  • DVI to VGA Adapter Closed Lid Mode Distorted Picture on TV

    Hi
    I managed to hook up the DVI to VGA adapter and view on my Sanyo TV. Nothing fancy just a older TV.
    I am feeding through the Yellow Video output into the video input on the TV. (Also tried s-video)
    Viewing with the macbook lid open no problems. Remembered that I could close the lid.
    Followed the instructions online about connecting, closing the lid and waking up using my bluetooth mouse.
    First time things went well - able to use Front Row and View Slideshows etc. also steaming video from Safari, (TV Land for my kid)
    Then the screen began to flash - and change to black with rolling images.
    Like you used to have in the 60-70's black and white TV - multiple images rolling past over and over.
    I tried rebooting - starting new connections, using different cables, using both VGA and S-Video directly into the TV and not through my reciever.
    Any ideas!
    I can't use closed lid mode at all. I must instead, dim my screen.
    Help?
    Thanks
    Buddy

    Thanks, BSteely, I have the latest QT and iTunes already. Closing the lid seems to kick the MacBook external display into some special mode that Front Row can't display videos in. For example, you get the Front Row interface, but as you select movies/TV shows, the preview window on the left side is blank. Open the cover, and have both displays going, and you can see the previews fine (and of course, you can see the movies/TV shows play fine as well when you click on them)
    Running Quicktime Player full screen works fine without Front Row in either open or closed lid mode. So it is apparently something wrong with Front Row itself.

  • TV + Closed-Lid Mode?

    Is running in closed-lid mode on the MacBook using a television with the Apple Video Adapter supported? I can't get it to work properly.
    Brian

    Make sure your power saving settings aren't unusual - I find normal works fine. Configure your external displays with the lid open and then with the power cable connected try closing the lid. It will fall asleep immediately - let it. Then when the light throbs try waking it back up again with the remote... It works for me, but it did try my patience before I came up with a routine that I was happy with.
    Also - how do you connect your TV? My TV has a monitor / DVI out and it's quite happy with that. I shouldn't think that S-Video should be too different. Has anyone tried with S-Video? Hope this helps...

  • 10.5.2 wake/sleep and closed-lid problems

    As of 10.5.2 my MBP no longer works correctly in closed lid mode using a hardware
    setup that previously worked flawlessly. After plugging in power and video, plugging
    in the USB keyboard seems to wake the system, but no video. I then must open the
    lid, unplug the USB and video and try to get the system to respond. I often must cycle
    the power to reset the system--very disturbing to do that.
    Also as of 10.5.2, I have had to power-cycle the machine when it has refused to wake
    in open-lid mode and this weekend I the entire machine froze (no mouse movement,
    no expose, etc) in the middle of work using a graphics-intensive program and I had
    to reboot by cycling the power.
    A friend also reported similar issue in which the system would not respond after the
    screensaver became active.
    Are others seeing problems like these? I am beginning to suspect that the post-10.5.2
    graphics update has problems.

    I just wiped my HD and reinstalled everything besides the Graphics Update. I can now close the lid of my MBP and use my external monitor alone. The Graphics Update had made that impossible.
    Further, I am in the habit of putting my MCP to sleep and putting it in a backpack in the morning, meeting friends for breakfast, and re-awakening it at the office. When I did get to my office, I found (as another user had on another thread) that the MBP, even closed, had woken itself up and was hot as heck. I am uncertain that sleep will work properly under 10.5.2, but I know that the display wackiness of the Graphics Update was driving me nuts. I will not install it until Apple fixes it.
    I looked around for awhile for a way to uninstall the Graphics Update, but could not find it...I suspect it exists somewhere.
    The 10.5.2 Combo update (343MB download) DOES NOT include the Graphics Update, and at this time, I seem quite ok with everything else updated.

  • EXTERNAL HDD NOW DISAPPEARS WHEN USING MY MBP IN CLOSED LID MODE

    I have an 15" MBP 2.53 running Snow Leopard, which installed fine. When I go to use it with my Apple 24" Display and my external hard drive, the external HDD disappears when I go into closed lid mode.
    The finder freezes too, and I can no longer enter into Time Machine.
    The external HDD does show up in disk utility, however.

    and please ... STOP SHOUTING!
    It doesn't make your message any more relevant or increase the motivation to help you. To be honest, it makes you look like a moron, if anything.

  • Turning off closed lid mode

    I was wondering if there was a way to turn off the closed lid mode feature. It's the feature that allows you to use your MacBook even when the display is closed by hooking it up to an external monitor, keyboard and mouse. The problem I'm having is that when I close my MacBook to go into sleep mode, I leave my wireless mouse dongle plugged in, when my mouse gets a slight bump the computer awakes from sleep mode and goes into closed lid mode, it's really really annoying. Help please!

    This is what you want.

  • Can closed lid mode damage new MacBook display?

    I would like to buy one of these new 24" LED Cinema Displays to use it with my new (late 2008) MacBook. Actually I would love to mount the display on my wall in order to use it at a TV with the MacBook (if longer cables are available).
    Apple advertises to use the new MacBook in closed lid mode with the build in iSight. Now I heard at my local dealer, that the MacBooks heating can seriously damage the internal display when the lid is closed.
    I allways thought that these two devicews are made for eachother. Do I risk to damage my MacBook when using as a video or TV source for several hours? Do I loose warranty?

    Thank you Malcom. I read these articles. They describe how you enter the clamshell (or closed display) mode. But I still feel that they don´t not really cover my question: Can extensive use of the Macbook in clamshell mode damage the internal display (for example while watching movies on the connected 24" LED Cinema Display)?
    It is just because this guy at the Apple dealer over here (GRAVIS) said something like: "oh - this is the worst thing you could do to your MacBook ..." and: "everybody is saying that ..." and so on.
    Has Apple taken specific care of ventilation in clamshell mode on the new unibody MacBooks? Does the heat then flow out of the rear of the machine or is the MacBooks glass display somehow less sensitive for heat?
    Thanks again.

  • Closed Lid Mode in Boot Camp...

    Hey guys.
    Before I go and splurge on a 24" external display...will it be possible to use something like closed lid mode under boot camp?
    Will also want to be able to use a bluetooth mouse and keyboard
    cheers

    Hi V.K., I followed the reset steps for PRAM and the problem still exist. Could this be the battery's problem? BTW, my laptop is still fairly new, got it in December.
    Thanks for your help

  • Closed-lid mode USB devices disconnect randomly

    I just recently connected my MacBook Pro to my Samsung DLP HDTV and started running it in closed-lid mode so my TV is the primary/only display. I also have an external hard drive (USB), external mouse (wireless with USB toggle) and the new Apple bluetooth keyboard.
    The problem I have isn't entering the closed-lid mode. But once in closed-lid mode (after a short period of time) all of my USB devices disconnect and then reconnect. I know this because I get an error saying that my hard drive was removed improperly (please eject before disconnecting, etc) and I also get a message from my mouse software saying that my mouse has been disconnected. But then they reconnect themselves (hard drive shows up again on desktop and mouse software informs me that the mouse is present again).
    Has anyone had this problem before where USB devices disconnect in the closed-lid mode? I just upgraded to Leopard (formatted the drive and started from scratch). I never tried this within Tiger so I don't have that for a reference. This is really annoying because I have my entire music collection on the external hard drive and it just stops playing when this happens and I have to restore the path to my music collection within iTunes' preferences (it defaults back to ~/Music/iTunes/ when it figures out that the hard drive is no longer there).
    The strange thing about this is that when I don't run in closed-lid mode this never happens. I'll be more than happy to provide more details if needed. I greatly appreciate your help.
    Thanks!
    Mike

    i appear to have the same problem under Vista (via Bootcamp) on MBP (2007). i close the lid, and 5-20min later i hear the sound a USB device makes when it disconnects, and a minute or 5 later it reconnects. i don't actually have any USB devices plugged in, but there are several components in the MBP that are connected internally via USB (DVD drive, etc).
    what's almost as annoying is that the LCD backlight will come back on of its own accord, even though the MBP's been idle for more than the LCD/backlight time-out period. after the next idle timeout it turns off, only to turn back on againa while later. i see this under OSX & Vista.

  • Difference between open loop and closed loop mode when finding the index on a stepper motor axis.

    I have a test system which uses a PXI-7352 motion controller with a MID-7602 stepper motor drive to position a 200 step/revolution stepper motor with an attached 1000 line encoder.  The MID-7602 is configured for 64 microsteps per step, giving 12,800 microsteps and 4000 encoder counts per revolution.  The system is controlled using LabView 7.1 and NI-Motion 6.13.  To home the motor, I've defined a sequence in MAX which first finds the reverse limit switch and then moves forward to the encoder index pulse.
    When finding its reference in open loop mode, the system its reference at the same microstep each time.  When findings its reference in closed loop mode, the system finds its reference somewhere within about a 20 microstep wide range.
    I hope somebody out there with more experience with this controller can describe the difference between finding the encoder index in open loop mode and finding the encoder index in closed loop mode. 
    Thanks,
    Mark Moss

    Hello Mark,
    I suspect that the behavior you are experiencing has today
    with the resolution difference between your encoder and your
    microstepping.  Let me illustrate with an
    example:
    Example Setup
    Stepper
    Motor
    NI
    Motion Controller
    10
    steps per encoder pulse (Every 10 steps the controller gets an encoder
    pulse, therefore positions 0-9 all appear to be 0 to the controller)
    The
    system has a maximum of 3 pull in moves set
    Open Loop Scenario
    The
    system is commanded to go to position 9.
    The
    controller sends out 9 pulses.
    The
    motor moves to position 9.
    Closed Loop Scenario
    The
    system is commanded to go to position 9.
    The
    controller sends out 9 pulses.
    The
    motor moves to position 9.
    The
    controller checks its position and sees that it is still at position 0
    because it has not received an encoder pulse.
    Because
    the controller thinks it is still at position 0, it sends another 9 pulses
    as its first pull in move.
    The
    motor moves to position 18.
    The
    controller checks its position and sees that it is at position 10 because
    it has only received one encoder pulse.
    Because
    the controller thinks it is still at position 10, it sends1 reverse pulse
    as its second pull in move.
    The
    motor moves to position 17.
    The
    controller checks its position and sees that it is at position 10 because
    it has only received one encoder pulse.
    Because
    the controller thinks it is still at position 10, it sends and additional
    single reverse pulse as its third pull in move.
    The
    motor moves to its final position of 16.
    I believe something similar is happening with your
    application as it looks for the index pulse. 
    Because the controller does not compensate for what it perceives as
    position error in open loop mode, the motor always goes to the same commanded
    position.  In closed loop mode, the motor
    is bouncing around inside the single index encoder pulse trying to find a
    certain position.
    There are several recommendations I can make towards
    correcting this behavior.  These
    recommendations are in order of effectiveness:
    Setup
    your system so that there are more encoder counts per revolution than
    steps per revolution.
    Turn
    off pull-in moves by setting them to 0 in MAX.
    Use an
    open loop configuration.
    Play
    around with the pull in window in MAX.
    Regards,

  • External display and "clam shell" closed lid mode = "Input Not Supported"

    I have an Acer AL2016W 20" monitor hooked up to my again Powerbook due to it having a cracked screen. It is working just fine right now, in 1680x1050, when the screen is open. Citing this article,
    http://support.apple.com/kb/HT3131
    I should be able to close it and have it working as well. When I do close it then wake it, I just get a "Input Not Supported" message on the monitor. Any help?

    I'm still puzzled at why it the screen is activated when the lid is closed and woken with an external USB device
    That's rather puzzling as the display should not work if the lid is closed. If you have an external drive you're able to install a clean copy of Mac OS X to and boot from you can see if the issue persist there. If it does then it's most likely a hardware issue and you should contact AppleCare. If it doesn't then it has something to do with either your software installation else some utility you've installed.

  • How can I circumvent this connection issue due to closed-lid mode?

    I recently purchased a new Samsung monitor and have narrowed down the deficient connectivity to the fact that the Wi-Fi antennae is located at the "MacBook Pro" area of my computer's monitor. I own a late 2009, 2.26 GHz MacBook Pro connected to a 2011 AirPort Extreme Base Station. Resetting the router and searching for the ideal channel still keeps my connection at a slow crawl when the lid is closed. I'm posting this question to see if there any developments in solvin this connection issue and whether or not there is anything I can do before purchasing an external antennae. Any and all help and greatly appreciated!

    I've had the same problem, everything was o.k. when lid is open but when I connect it to external monitor and close the lid, wifi signal is very week or there was no signal at all. I tried moving macbook all over the room and nothing helped, untill I tried to open the lid just a little so that macbook monitor stays off, immediately my wifi signal was normal again, strong as it is when I'm using it whit lid open.
    I hope it will help you to.

  • Cannot use clamshell ( closed lid ) mode

    I have a very annoying problem with my MBP in clamshell mode. I used to use my computer in clamshell mode with my external monitor while plugged into the ac adapter. Once in a while when I want to use it in clamshell mode I try waking it up with my bluetooth mouse or keyboard and it wakes up and my monitor shows my desktop for about 10 sec, before it goes back to sleep. I try again and something happens. Sometimes it continues to wake up on its own before falling asleep again. This didn't happen before when I first bought it. Is anyone else having the same or related issue?

    I can relate to this. I use my MBP mostly in clamshell mode. Transitions, plugging in and unplugging the external monitor, and other accessories, I do mostly with my fingers crossed and prayers to the patron saint of electrons. Sometimes I get the results you describe; sometimes, something even more odd. It's worth remembering that the external display doesn't necessarily mirror the (closed) laptop display — I find it has a different background, and of course it has different resolution and proportions as well. So some thinking and re-organizing is required on the part of the computer to change primary displays in that fashion. Two things I do to facilitate the change are (a) to put the computer in sleep mode before attaching or detaching the display, and then unplugging the AC power first; and (b) ejecting external drives before they are unplugged. Even if it's asleep, the computer objects to having a USB connector to a mounted external drive removed.
