Clamshell (display closed) mode

Hi,
I am using clamshell (display closed) mode from a while after a recommendation from someone in the discussion (many thanks!). It is great for my needs, but the thing is sometimes it is hard to start this mode. I find myself trying several times to make it works opening the macbook and closing it. Is there any special key or something to start it up for sure in the first shot?
i have a macbook pro + external aluminium keyboard + samsung syncmaster 2263 UN
thanks,
How to use your computer in closed clamshell (display closed) mode with an external display

Thanks Malcolm - I guess there isn't a solution to this problem unless some cooperate entity steps up to the plate and in this economy I don't see that happening. So, 5 to 7 years down the road someone will win a lawsuit and all of us consumers will get some type of rebate or other incentive that won't make up for the problem. Thanks for the links to the articles.....

  • MBP in closed clamshell (display closed) mode with an external display

    I want to use my Macbook Pro Unibody in closed clamshell (display closed) mode with an external display

    but i still have doubts about it the temperature and the Screen.
    Thanks..

    Apple says closed clamshell mode is a valid way to operate a Mac notebook, so that should be assurance enough. I don't know where the notion comes from that non-operating LCD screens can be damaged by heat. It would take a lot of heat to do damage. Way more than can be supplied by the computer itself.

  • Possible to disable closed clamshell (display closed) mode?

    I would like to disable the closed clamshell (display closed) mode on my MBP, where you can run the computer with its lid closed if it's attached to an external monitor. I don't ever do this (I use the MBP screen as a second monitor), and this option causes my computer to randomly wake up if I turn off/on my office lights, or accidentally press a button on my usb keyboard or mouse.
    I know there is no option to turn this off in the System Preferences, but is there a terminal hack that can do this?
    Thanks!

    If I understand you correctly, you don't close your display (because you use it as a second monitor) and sometimes you put the machine to sleep with its display open. But turning your office lights on or off wakes the computer from sleep (which certainly indicates an electrical problem in the office wiring or lighting, and one that can't be good for your computer). And of course hitting any key on the keyboard wakes the computer too, exactly as it's supposed to do. If I understand all this correctly, what if anything does it have to do with clamshell mode, and what particular aspect(s) of clamshell mode do you think you need to disable, and why?
    While you're thinking that over, I recommend connecting your computer's AC adapter to a high-quality surge protector or an uninterruptible power supply that features power filtering.

  • How to make computer run in closed clamshell (display closed) mode without having an external display

    i want to listen song closing my display how to do it any idea???????????

    You can run a MacBook Pro with its display closed with the aid of any of several third-party hacks that prevent sleep, InsomniaX being one. If you put your closed and still-running Mac into a padded sleeve, backpack or carrying case that prevents it from ventilating itself, it will overheat and cook itself and/or cause a fire. Therefore, I strongly recommend against using any of the anti-sleep hacks, and if you do so, you do it at your own risk.
    A MBP is not an iPod. If you want an iPod, get an iPod.

  • Overheating in clamshell (display closed) mode with 24" LED Cinema

    I have a new (1 month +) Macbook Pro 15" 2.4 GHz attached to a Apple LED Cinema Display....whenever I use the display in the "clamshell" mode using the "Higher Performance" option my system heats up dramatically. The fans never stop running and the machine never cools down. However, when I use the "Better Battery Life" option I never get the increase fan and the system does not heat up.
    I have read a few articles that there are problems with the new NVIDIA 9400 cards - but does this pertain to my particular setup? Are there any known issues or solutions to this particular problem?

    In "Better Performance" mode, you are using your MBP's more powerful 9600M GT graphics processor, and your machine runs considerably hotter than when you use the lower-powered 9400M GPU. The fans in your MBP run at all times; speeds range from 2000RPM at idle to 6000RPM flat out. Fan speed should ramp up at temperatures of 80-90° Celsius. If your machine gets to 105°C., it is in danger of overheating and will sleep to protect itself. At lower temperatures than that, it is not overheating. Use iStat Pro to monitor the temperature sensors in your MBP, along with many other aspects of its operation.

  • Computer freezes in lid-closed mode when connected to external display

    I have a Sylvania SC190 CRT display connected to my Powerbook via a VGA to DVI adapter. Every time I put the computer in lid-closed mode and try to run it off of just the SC190, after a few minutes it freezes up and I have to hard restart it(hold power button down).
    Now, a few days ago, my powerbook stopped recognizing the display as an SC190, and just recognized it as a VGA Display. Don't know if this is relevant, as I have never used lid-closed mode before.
    Does anyone know what the problem is, and/or what I can do about it?
    Thank you.
    PowerBook 15" G4 1.67 GHz   Mac OS X (10.4.8)   512MB, 80GB, SD-DL

    I have the exact same problem.
    Here's my story:
    To give you some backgroud, my setup involves having the macbook on a mstand hooked up to an external monitor. I run a usb hub from my macbook, this is where my mouse transceiver is plugged in. I use am Apple wireless bluetooth keyboard (latest slim model)
    I recently purchased the 13.3' inch 2.26 MBP as I gave my older 2.0 uMB to a family member. The computer is in the stock configuration with no hardware upgrades.
    I have noticed weird behaviour when waking the computer from sleep when the lid is closed. When i wake the computer up (by tuning on bt keyboard), the keyboard light blinks like there is not bt connection and the computer will wake in an inactive state. The led light will be on, but when i flip the screen up....nothing. Screen is dark, keyboard pressing does not illicit any responses. I have to do a hard reboot by holding down the power button to restart the computer. Unfortunately any previous data or work is lost.
    I work in IT so I completed troubleshooting and also things outlined on forums in google. Reset PRAM, reset SMC and also reinstalled OSX. Still I get the same result. Fearing I purchased a defective unit, I called Apple and they told me i could exchange the computer so I dropped by the apple store and exchanged it quite easily.
    I've spent hours restoring from time machine and I am experiencing the same issue on my new laptop. I'm now assuming its not hardware but more firmware related as I had to do a bluetooth firmaware upgrade when I bought the computer when I checked for software updates.
    Is anyone else having any wake issues with their new MBPs? And what should I do next? Should I exchange for a 3rd unit? Thanks for you help everyone.

  • MBP in lid closed mode, will the display get to hot?

    i run my MBP in lid closed mode all of the time, as i have a Cinema Display hooked up. i'm not too worried about the MBP overheating, but i was wondering about the display getting extra hot from the MBP when it's closed. i do have a radtech microfibre cloth on top of the keys as protection...
    should i be concerned?
    17" MacBook Pro   Mac OS X (10.4.8)  

    I'm interested in this issue too, as I intend to get an MBP but use it with an external screen and keyboard most of the time.
    I'd also like to know about ventilation - where does the cooling air come from and go to? What parts need to be kept clear, and which bits can I have up against or close to a bookshelf or hutch or whatever?
    Thanks in advance.
    PS, I think the glossy screens look fantastic, but also think I'll go for matte since they are more practical.

  • Lid closed mode--ntsc and pal

    I used to be able to put my MBP's display onto a TV using lid-closed mode and the Apple DVI-video adapter. I was changing my TV's resolution to something slightly higher, clicked the wrong setting (set the display mode to PAL), and now whenever I use lid-closed mode (or when I use boot camp to boot into windows XP) my TV (NTSC) does not work. It only does this in lid closed mode, and I've reset the PRAM to try to fix it. I can't see the TV display in PAL mode, so I can't change it back to NTSC. Please help!!! Should I reset my PMU or use some EFI command?
    15" MBP   Mac OS X (10.4.7)   using composite video on dvi-tv adapter (ntsc)

    I recommend running both the MBP (lid open) and the TV at the same time in screen spanning mode (not mirror mode). In this way, you should have complete control over the TV's Display Preferences settings from the screen on the MBP. Make sure you have the "Show displays in menu bar" check box clicked in Display Preferences. You should be able to restore the old settings you were using for your TV with this technique.
    Once you get your old settings restored, you can go back to using just the TV with the MBP lid closed again.

  • Closed mode glitch

    For a couple of weeks I’ve been very successful in using my MacBook Pro in closed mode with an external display. Once the closed system was in operation I would put the MBP to sleep at night, turn off the monitor, and next day turn the monitor on, touch a key and connect to the Internet, all very smoothly.
    But yesterday I rearranged my office, and closed mode has been very iffy ever since. The Internet rarely connects without my having to shut down or restart the MBP several times, and then, if I close the lid the connection cuts out. Trying to solve the problem, I’ve taken all the plugs out and reinserted them to no avail, gone through the connection start-up process from scratch, and even given the system 24 hours ‘settling down’ time in case it needed it to adjust to the new position in the room – no improvement.
    This posting is written on the MBP with the display not connected. And it's fine. But the display worked with it before, so why not now? I must emphasize that it is only the Internet connection that causes problems when the display is connected - oh, and the occasional freezing of desktop files.
    Any thoughts, please?

    Hi Uxenden, you might want to move this post to the Macbook Pro forum; this is the Mac Pro forum. You will probably get better answers to your problem there.

  • Resuming sleep from lid-closed mode?

    Sorry if this has already been answered, but searching through the manual and 34 pages of previous posts didn't turn up anything.
    When I get to work, I connect my MBP (in sleep mode) to my external monitor and then to my usb keyboard/mouse, which triggers the computer to wake up and go into lid-closed mode. I work all day with the lid closed.
    The problem is that when I'm ready to leave at the end of the day, I cannot just disconnect everything and resume sleep mode for the transport home.
    If I go to Apple/Sleep, it'll go to sleep for 1-2 sec, then re-enter lid-closed mode. If I unplug everything, then the computer stays in lid-closed mode and won't go to sleep. The only way to get it back into sleep mode is to disconnect everything and open up the lid, wait for the display to come on, then close it again. Time consuming measures like this clash severely with my impatience at getting out of the office.
    Any tips on how to re-sleep from lid-closed mode without having to open the lid? Thanks in advance.

    My impatience was my own undoing. Upon further testing, once the magsafe is disconnected, the laptop begins the routine to go to sleep. I'm a very happy camper now...don't have to open the laptop at all, and I get to reduce the rate of dimming of my laptop screen.

  • Bezel separating? / lid closed mode

    I've been operating my MacBook in lid closed mode for a week now. This morning I noticed that the plastic bezel on the left side and at the bottom of the display are starting to display small gaps with the LCD. Is this something I should be concerned with? Thanks.
    MacBook   Mac OS X (10.4.7)  

    This is my question too, so to save a new thread I'll chime in here.
    When I used an ibook, extensive googling yielded the concensus that the ibook should definitely not be run with the lid closed as the machine is ventilated through (or partly through?) the keyboard. In contrast it was said that lid closed mode was fine for the powerbook which was ventilated through the case somewhere.
    As far as I can tell the ibook and macbook have pretty similar cases, including what I assume is a vent at the back. (Actually on the ibook it looks more obviously like a vent, as it has a grill.) I don't have access to a powerbook to compare.
    So I guess that still leaves me asking whether it can be confirmed that the macbook is definitely safe running with lid closed (which is how I've been using it). Is the rear vent on the macbook more efficient than on the ibook? Or is the thing on the back of the ibook not actually a vent at all? ???
    Can anyone shed any light?

  • MacBook Pro, Lid-Closed Mode

    Hello, I'm considering getting an Apple Cinema Display to use with my MacBook Pro. I understand that most modern MacBooks, including the Pro are lid-closed mode compatible.
    A) I understand that one must have the display, keyboard, and mouse to use the notebook in lid-closed mode. Is it true that the Apple Wireless mice and keyboards are compliant as well? If I've read this article correctly, then yes:
    http://support.apple.com/kb/HT1308?viewlocale=en_US
    B) The screen doesn't turn on, back inside the notebook does it? That would be a redundant use of power.
    C) Is lid-closed mode harmful to the longevity or otherwise well-being of my MacBook Pro?

    Is it true that the Apple Wireless mice and keyboards are compliant as well?
    Yes.
    Is lid-closed mode harmful to the longevity or otherwise well-being of my MacBook Pro?
    No.

  • Problem with lid closed mode

    So as far as i know, to get the computer to run in lid closed mode you press f7 until you get video mirroring, the second mode i believe, close the display, then wake the computer with the external mouse or keyboard. I've done this, but almost as soon as i wake the computer, it goes back to sleep again.
    How do i fix this??
    Is it a problem for I'm using a windows keyboard, but i wouldn't think that could be it.

    Also, if you haven't already done this, make sure that Bluetooth is enabled and that you "Allow Bluetooth devices to wake this computer" (Systpref/Bluetooth/Settings)

  • Macbook - External Display - Closed Lid

    Hi there,
    I know full well that the powerbooks and the macbook pro run monitors in lid closed mode... but does the Macbook?
    I would only do this without a hack as I do not want to destroy warranty.
    If it doesn't, it may be time for me to look into a 12" powerbook G4.
    I had to sell my iBook and I want something for presentations and to travel with. If I sell my iMac, I'll need a big display as I am not going to just look at a laptop display all day.
    Thanks, Martin

    "it'll run in closed book mode with the external display. it may overheat however, so i'd be careful."
    I don't want to sell my iMac and then break a macbook...
    I used to have an iBook G4. Then I bought an iMac. Now I want a laptop, but know that if I get one, I'll want a desktop again...
    What monitor do you use? I can't find any white ones...

  • Simulate lid closed mode

    Do you know if is possible to use a software utility to simulate the lid closed mode for use with external display?
    I would like to use my macbook pro only with external display without close the lid, is possible?
    Thanks

    I have two suggestions:
    - If you close the lid and then wake up the Mac with a USB device like a mouse or a USB flash memory drive or some other USB device, then only the external screen will be active. Once the external screen comes on, you can open the lid and the internal screen will remain off. You have to have the MBP power adapter plugged in for this to work.
    - You can also use a small magnet to simulate a closed lid. Just place the magnet on the right edge of the plam rest over the area that is above the security port on the right side. This will make the MBP think the lid is closed.
