Closed lid clamshell overheating[?]

Hi, I have a macbookPro late 2009 running Mountain Lion OS, I started to use the computer in Clamshell mode where so far I was aware about ventilation issues hearing here and there incidents about overheating and stuff concerning using the computer with closed
Iid, are there any particular problems with that nowadays and any precaution actions I should be aware before I roast my machine ?
As far I can tell now relating on posts opinions are controversial.
I am an audio proffesional and sometimes I am using it full day with no break.
Thanks
K.

Can't be done. Unplug USB devices before closing the lid.
Should that happen again, you can force a hard restart by pressing and holding the power button for a few seconds.

  • Problem running in closed-lid (clamshell) mode?

    New 2.4 glassbook, upgraded to 4Gb Crucial ram, using bluetooth mouse and keyboard, with external Dell 2007FP monitor.
    With my old MBP in sleep mode, I could connect the monitor, ethernet, and power, and when I plugged in usb with the lid still closed, the laptop would turn on and everything worked in lid-closed mode.
    Now with new glassbook, do the same thing (using display port to DVI adapter), the machine whirrs up, the display turns on (without top menu), and then the laptop goes to sleep. Tried it on a different monitor, same problem.
    Am I the only one with this problem of the glassbook not wanting to operate in lid-closed mode?
    Thanks in advance.

    Yes, same problem. Swapped memory chips back to Apple, same problem. Reset SMU and zapped pram, same problem. It's gonna suck if I have to exchange the laptop because I've spent a day migrating over. I'm hoping it's just a defective DP-DVI adapter. I've also noticed external display flashing (losing signal) as detailed in this thread: http://discussions.apple.com/thread.jspa?threadID=1756755&tstart=0 This makes me worry it's not just the adapter but a problem (driver or hardware) with the 9400M. Can someone else confirm they can operate in clamshell mode without problems?

  • HT3131 With the lid closed in clamshell mode, the lid covers the fans - won't it overheat?

    With the lid closed in clamshell mode, the lid covers the fans - won't it overheat?

    This is useful but the MBA gets a bit hotter due to intake, but if you have the lid open + external screen it gets even hotter due to more for the GPU (processor) to do.
    Only way I’ve manage to run only external screen with the lid open is to trick the MBA that the lid is closed with a magnet positioned on the left.
    I’d really like a software solution to this though…

  • Closed lid, fans always running

    Howdy. I've been using my MBP in closed lid mode attached to a Cinema Display. I expected the fans to run constantly when in use, especially with XP running in Parallels. When I put the computer to sleep--still attached to monitor, usb keyboard, bluetooth mouse and power adapter--it acts as I suspect it would, fans stop, front LED starts fading in and out. However, I'll come back later and the LED will be solid, display blank, and the fans running away. The keyboard or mouse will wake the computer and then it runs as normal. This has happened overnight as well as in half an hour, and several times.
    I am kind of getting concerned about using the computer this way. Fans always fail, and I am not really looking forward to opening the computer up again.
    I guess my questions are: why would the computer be running the fans, especially after being in sleep for hours, and is it shortening my MBPs expected life using it with the lid closed?
    Thanks.

    I'd guess/assume that something is actually waking it from sleep and causing the heat/fan activity and that when you return you're not actually waking it up just re-activating it from screensaver mode ...
    Run Utilities/Console and click 'All Messages' top left - what lines appear during the time you think it should be sleeping ?
    It isn't shortening the life of the hardware using it in clamshell mode but if something is causing it to overheat regularly that will have an impact on internal components/motherboard that could be detrimental.

  • 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.

  • 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.

  • 15-r007TU-Display does not turn on when it automatically turns off after closing lid.

    I just purchased hp 15-r007TU, Windows 8.1 x84. I'm facing a strange problem. After all initial setup, I put the laptop on to download and install all lates Windows 8.1 patches. The display is set to tuen off automaticaaly after 5 minutes. After 5 min it did turn off as set. But then I can not turn it back on. I pressed all (except power) keys, used touch pad, closed lid and opened but it stayed off. Laptop was on and running as I could see HDD lights flickering, I could hear system sounds on pressign mute/volume keys, also I could toggle WiFi with key. I then pressed power off key to turn Windows off normally. I did turn off. I again turned it on, I could see 'hp' logo with spinning wheel and then nothing. Display is off and I don't see start screen. I have to hard reset (press power button for more than 5 seconds) then display is normal. This happens every time the display turns itself off automatically after set time or I close the lid. Only after hard reset it works normally and I see the start menu.
    The power settings I use are:
    1. never put system to standby after preset time. (either on battery or AC power)
    2. turn display off after 5 min. (both on battery or AC power)
    3. when I close lid - do nothing. (both on battery or AC power)
    4. when I press power button - shut down
    I am using Windows 8.1 x64 with all latest patches installed. BIOS updated to lates available. All latest drivers installed.
    I have not yet set password to the system to log in.
    Help would be immensly appreciate. The device is still in warrenty if it needs to be replaced.

    Hello K1200LT,
    Welcome to the HP Forums!
    I understand the computer will not sleep when you shut down the lid. You seem to have already done most of the troubleshooting I would've suggested.
    To be honest,  it is either a hardware or software-related issue. To determine this, I would like you to reinstall the operating system. It will clear up any software conflicts and allow you to start fresh.
    First, please ensure you backup your files. Here is information on how to do this: Backing Up Your Files (Windows 8)
    Once this is done, it is safe to reinstall the operating system. Performing an HP System Recovery (Windows 8)
    If the same situation occurs, the computer likely has faulty hardware. At that point, please contact HP phone support. You can utilize this website to learn how to contact HP appropriately, based on your region: Contact HP Worldwide
    Please let me know what happens. Thanks!

  • Closed Lid Operations Wont Work

    I am a big fan of the closed lid with external mouse, keyboard, and display (minimize spill risks in college dorm room). I just got a new macbook pro after 4 great years with my g4 powerbook and I cannot get the new machine to work with the lid closed. I have tried working with both displays then closing it, but it won't wake up. I tried putting it to sleep and attaching the external display but it doesn't wake up. The for either if I try to open the machine to use it normally the built in display, keyboard, and trackpad are non-responsive and so are all my external items. Has anyone else had this problem or any ideas on what could be going on.

    Jonathan , I am experiencing the same exact problems with my Macbook Pro 15 inch. I first started noticing about a month ago that the computer was getting unusually HOT to the touch , and after one day I set the lid down, when I tried to open it back up, it remained on , but no screen, and unresponsive. I have had to restart it everytime since then. It also now takes a lot longer than usual to reboot. I hope the people at Apple resolve this soon, because this is WAY too expensive to be having these problems on a new machine Ive only had for 5 months.

  • 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.
    Cheers,

  • 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.

  • 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,
    C

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

  • 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.

  • 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
