MBP running hot when connected to Cinema Display

I have a 2.33 MBP that I use for work and at home. I also have a 23 inch Cinema display on my desk at home. I have noticed that when I have my MBP connect to the Cinema and the screen on the MBP closed it runs hot and the fans never seem to stop running. I was wondering if anyone has seen the same thing and if so what they have done to resolve the issues. I have had looked at the laptop coolers that go under the laptop and that powers the fans off an USB port, but I really like my desk clean and don't want to add something else to it. Any ideas or suggestions would be great.
Thanks
Matt

Try running with the lid open and see it temps drop.

  • 2011 MBP shuts down when connected to external display

    I've been using my 2011 15" MBP for about a week now with no problem until today when I tried to connect it to my old 20" cinema display. I have the mini display port hooked up to the dvi adapter and a usb connection hooked up to external keyboard and mouse. Everything works just fine if I keep the lid up on the MBP, but if I shut the lid, the MBP shuts down. Down, not that the big screen goes black & then comes on again. It turns itself off.
    Any way I can avoid a trip to the Apple store? In the past, the "geniuses" knew less about external displays than I did. Is there an issue because of the dual graphics cards?

    no - I realized later that the machine doesn't shut off it just acts like it. The hard drive stops spinning & the screen remains black no matter what I do. This doesn't happen when I just shut the lid & then go back to working on it.
    Then if I shut it again & try to get the monitor to respond, I get a blue screen of death color with a two inch band of blue noise along the left side. Very weird.

  • I want my MacBook open and its screen dark when connected to Cinema Display

    I have a c. 2009 MacBook Pro running OSX10.8.3.  When gaming I want to use my Cinema Display (only) with the MacBook open and its screen dark, in order to facilitate cooling and conserve video card resources.  Is there any easy, safe, reliable, non-technical way to accomplish this?? I have searched the Web and found everything from using a magnet to reprogramming to using Hot Corners.  Using Hot Corners seemed to have good potential but I can't seem to make that work.  I don't want to reprogram my computer whenever I disconnect it from the display.  I am afraid a magnet is not good for the computer.  And I really find it hard to believe that something this basic should be impossible!

    Hi Squiji,
    Turn the brightness control all the way down
    does that count as an easy, safe, reliable, non-technical way?
    Another nice trick:
    ctrl+shift+eject
    instantly darkens your screen to black.
    You can return to normal brightness by pressing any key or the trackpad.
    very handy when somebody like your boss unexpectedly comes in, and you don't want him to see your 'confidential information' :-)
    Don't know how this behaves with a second screen attached though, I assume that goes black too but you can try it.

  • Cannot use boot keystrokes when connected to Cinema Display

    Hi there,
    Just a confidence check:
    I've just (at last!) upgraded from a 15" Studio Display ADC, to a 20" Cinema Display ADC (shiny Apple logo, not the graphite one). I am using the standard Apple Pro Keyboard w/black keys that came with my system (profile below).
    However, unlike with my 15" Studio Display, I find that I am unable to use any of the boot keystrokes when the keyboard is connected to the back of the Cinema Display:
    C: boot to CD/DVD
    T: boot to Target Disk Mode
    Option: boot to Startup Manager
    Command-S: boot to Single-User Mode
    Command-Option-P-R: reset PRAM
    Command-Option-O-F: boot to Open Firmware
    The keyboard functions normally once the boot process has completed, and the aforementioned keystrokes do function properly when the keyboard is connected directly to the Power Mac G4.
    My initial thought was that the Cinema Display is (presumably) not making USB devices connected to it visible to the ADC/USB bus until sometime during the Mac OS X boot process. However, I'd be surprised that the more capable/expensive/newer Cinema Display would lack functionality present in the older Studio Display.
    Any thoughts on this one?
    Thanks much for looking,

    Hi Keith,
    Thanks for the follow-up, but as I'd noted in my original post, I am using a Cinema Display 20" ADC, and not one of the newer displays (the ones in the aluminum enclosure that have a separate power supply, and use a DVI video connection).
    I do appreciate the look, of course!
    Best wishes to you,

  • Use Thunderbolt when connected to cinema display

    I have a macbook pro that I connect to a cinema display using thunderbolt. is there any way to then also plug in a thunderbolt device - such as an external harddrive that uses thunderbolt so i can take advantage of the speed? the only thing i can figure out is unplug my laptop from the cinema display so i can plug the external directly into the laptop. but i'd love to keep working on my big monitor! my cinema display is a couple years old and has 3 USB connections in the back, but no thunderbolt one. Thoughts? Thanks!

    If the drive has two Thunderbolt ports (many do), use that as the first step in the daisy chain, and cable the monitor to that.
    You could also look for a Thunderbolt dock which has a separate video output (often HDMI) to which you would add an adaptor for mini-Displayport for your cinema display.

  • MBP runs hot when in Bootcamp (xp)

    Any ideas why this could be happening? I currently am running two tabs in my browser and Skype. Dont think these two should be asking too much of my MBP. Any remedies would be appreciated.

    I have the same issue with Vista which is probably normal. And the only thing I can speculate on is that I only have an option of using the 9600GT which requires more power and produces more heat. I'm sure the energy management that was given to us for Vista or XP is not optimal. I could be wrong but Vista x64 sure does eat up the battery power. There is no complaint from me I just accept that Vista or XP is a different OS and pretty much a power hog to run optimal even running apps that doesn't require muscle. When running OS X with performance settings I get basically the same heat as running Vista x64. They tell me this is perfectly normal.

  • MBP runs HOT when playing online games

    Hi,
    Yesterday I was playing online flash games and istatpro reports the fans were running at 4500rpm (they were very loud). Today I am running the same game and the fans don't run higher than 2800rpm with the cpu temperature at 92 degrees Celsius. Is this cause to be concerned? I got this macbook pro about a month and a half ago so if something is not functioning right I have free genius repairs.

    Oh and random question: is it advised to keep the lid open when doing that graphics intensive stuff? Does that allow it to cool easier?
    Yes, I'd say that's advisable when you're doing demanding work (or play) with it. All of its internal air circulation takes place through the vents below the display hinge, but it would certainly be able to radiate away more heat from its top case surface with its display open. You can also improve cooling by raising its back edge an inch or so to allow freer air convection underneath the bottom case.
    When you're just emailing, word processing, working in spreadsheets or doing other low-demand tasks, the machine will stay quite cool in clamshell mode. No need to open it then.

  • Macbook air runs hot and makes noise like processor running hard when connected to display - even when not actively using air book

    macbook air runs hot and makes noise like processor running hard when connected to display - even when not actively using air book

    You could use the free tool iStat Pro to see what changes when you connect your MBA to the display. Without doing anything the CPU pane should show a high percentage for "Idle". If the idle value is too low, launch the Activity Monitor and sort by CPU usage. There is a pane showing the different temperatures of your computer. Watch them for a few minutes after connecting the display.

  • I have a MacBook Pro 15" 2.53GHz Mid2009.. updated to Lion which is now 10.7.3 build 11D50b... when I close lid and connect to Cinema Display, display will not activate... disconnect display, open lid laptop display will not activate... used to work fine.

    I have a MacBook Pro 15" 2.53GHz Mid2009.. updated to Lion which is now 10.7.3 build 11D50b... when I close lid and connect to Cinema Display, display will not activate when keyboard/mouse used... disconnect display, open lid and laptop display will not activate... only way out is hold power button.  Worked fine before Lion update.   Any Advice?

    Thanks very much Coander15... I've printed the doc you pointed me towards and I'll run through it.. hoping it helps!
    Before I installed Lion I simply hit any key on the keyboard or clicked the mouse...
    The keyboard is USB (usually connected to monitor which is connected to laptop... have tried direct connect to laptop as well with no luck) and mouse is USB wireless to one of those tiny plug in's... have tried direct connect USb mouse as well with no luck.
    I could plug the closed/sleeping laptop into the monitor and unplug from the monitor without incident all day/night... always worked fine. 
    Had heard something about this happening w/ Lion but went ahead anyway. 
    Oh well...
    Hoping your pointer helps... will let you know how it turns out.  Thanks very much for responding!!!

  • How do I connect a new Thunderbolt MBP to and old 23" HD Cinema Display ADC port

    A question Im sure many have asked but I cant find a straight forward answer.
    I simply will be buying a new thunderbolt MBP 15 and NEED to connect it an old 23" Apple Cinema Display that uses the old ADC connector.
    Can I do it and if so how? I realise theres a potential under powering issue?
    Thanks

    Hello Sigh
    I am sure there is no way to get your ADC connector display to function with your new Mac Book Pro.
    I tried everying I could and gave up and purchased a 24" Apple refurbbished Cinema Display for $599 + tax on 4/27/2011. The Apple part number is FBXXXXL/A, Model A1287.
    Gave my  year 2002 ADC 22" display to a friend.

    Re: How do I connect a new Thunderbolt MBP to and old 23" HD Cinema Display ADC port Jul 8, 2011 4:58 PM (in response to Russy47)
    Got my new MBP 2011 today. Hooked it up to my 23" Apple Cinema Display fine, using the Apple DVI to ADC converter > Mini Display port adaptors. I could then mirror display, but only at 1440 x 900 resolution.
    My dream is to have it like my old laptop--I mostly leave it shut, and main display is on the Cinema Display. So far, if I close the laptop lid on my new MBP, display shuts off. Also, can't get it to bump up the resolution to 1920.
    Sigh.

  • MBP Kernel Panic when connecting to HDTV (DVI)

    I have a 15" MacBook Pro that has been working perfectly since I got it. I tried today to connect it to my Hitachi 51" HDTV (via DVI) and got an instant Kernel Panic. I used my 15" Powerbook with this HDTV without any issues.
    I've searched and found folks with kernel panics when waking their MBP if the RAM is faulty, but nothing at all about issues when connecting an external display. I am running with all the latest updates, firmware update, etc.
    I don't have any problems connecting to a 23" Cinema display or to a 19" Samsung LCD, but I tried several times to connect to the HDTV and got a kernel panic each time. I changed resolutions on one try and still got the same issue (720x480 so the TV would see it as 480p). I even tried booting up with the display already connected and it kernel panic'd when it tried to switch into the full OS X GUI.
    The specific error is in the panic.log is:
    Sat Jun 10 16:23:48 2006

    What happens if you boot from the DVD that came with the MBP instead of booting from your hard drive? It could have something to do with your configuration.

  • Cannot change display resolution when connected to external display

    On my 2.0GHz 13" MacBook, I have no problem with the display resolution when connecting to external display/projector when I am running in Mac OS, everything work perfectly! But things start to get messy when I am running in Windows VISTA 32 (installed within the Boot Camp 2.1). Whenever I connect to any external display/projector via a MiniDisplay-to-VGA cable, the resolutions on both my MacBook LCD and external display/projector drop to 640x480. And i am not able increase the resolution in the Display Settings. Does this mean that I have not installed the latest version of display drivers? Or is it that Apple did not provide the VISTA 32 drivers (in Boot Camp 2.1) that is compatible with the Mini Display port.

    Cool!
    I'm glad you have it fixed.

  • Connecting DVI Cinema Display and VGA Projector from Minidisplay Port

    Hi Everyone!
    I'm trying to get my mid 2011 Mac Mini to send a signal from my MiniDisplay Port to a vga splitter which works fine. My biggest thing is that when I connect my inFocus IN112 VGA Projector the screen shows up from my mac but to connect my Cinema Display it takes VGA so I had to go from the VGA Splitter on one side and use a vga to dvi adapter and my cinema display shows blank? Help Me Please!!
    Thanks,
    Andrew

    I already have a converter on the end of the VGA Splitter to go to the Cinema. The reason I don't use the hdmi to dvi is because with the minidisplay port using vga to the projector and the hdmi going to dvi to the Cinema it makes the projector screen very rough and pixely

  • HT1825 Can I connect post cinema displays to my G4 and how?

    Can I connect post cinema displays to my G4 and how?

    You can use newer monitors but there are different ways to connect.
    It all depends on the video card installed in your computer. Different model cards had different ports. My G4 MDD has the ATI Radeon 9000 with one ADC port (abandoned technology) and one DVI port (useful technology). So we need to either see the description of your graphics card from System Profiler >Graphics/displays, a photo of the ports on your card, or both.
    As long as you find a monitor that shares the kind of ports on your Mac, you will be fine. I have a 2008-vintage LCD monitor on that circa 2003 MDD of mine. The MDD shipped with an Apple DVI-to-VGA adaptor so I can connect any monitor with DVI or VGA ports.
    There is an inconsistency in your equipment profile: No PowerMac can run OS 10.6. Please do "About this Mac" and verify your processor type and Mac OS version. Then you can edit your profile to avoid future confusion.
