HT3131 Will running the Macbook Pro 2011 in clamshell mode affect heat dissipation at all?

I'm worried about the heat not being able to escape when the laptop is closed.

I have used my new mid-2012 MBP in clamshell mode and monitored the temperatures and they were no different than when the lid was open, so it appears that the cooling system is unaffected. Very little heat dissipates upwards through the keyboard/upper case anyway, the heat is directed through the rear and underside of the case.

  • HT3131 Is there a way to use 2 external monitors with the MacBook Pro in closed clamshell mode?

    My internal display on my MBP is having issues and occasionally displays white lines all over the screen. The current external monitor displays properly. Is there a way to use two extrernal monitors intead of one external + the internal display?

  • MacBook Pro 2011 - 15" Core i7 - SSD - Heating, Screen Flickering Issues

    Hello,
    I recently brought MacBook Pro 2011 15" Anti-glare High Resolution with Core i7 2.2 G Hz, SSD, 8GB of RAM. I installed Microsoft Office and Angry Birds at this time. I'm facing multiple issues with my first Mac. Is anyone facing these kinds of issues in new MacBook Pro 15" models?
    Issue 1: Heating: Fan running on high speed even though room temp is below 60F. No major applications are running at that time expect Office 2011 and web surfing (NOT watching any video) and listening iTunes.
    Issue 2: When I log-off from computer, the screen flickers and goes to lower resolution. Also the windows colors changed to different colors. After log-in, I went to System Preferences > Displays. The highest resolution is already selected (1680 x 1050) When I try to change to lower, it changes but still displays different window colors and changing suddenly.
    Troubleshooting Steps:
    1.) Shutdown and Disconnected Power Cable (at that time battery is at 65%)
    2.) Reconnected Power Cable and Power On the system
    3.) Display shows correctly.
    Unable to Resolve:
    1.) Still fan is running on higher speed at low temp (below 60F with no major application running)
    2.) Sometimes Display is not showing properly. It shows different color shades.
    I scheduled support call with Apple Support and let's see what Apple can do...

    I brought my first MacBook Pro 2011 on Day 1, so I can't return it since it won't come under 14 day return policy. I'm taking my Mac to Apple Store to fix all these issues. AppleInsider is also confirmed Disaplay Flicker issue on some of the models that they tested.

  • How to keep display on Macbook Pro instead of Clamshell Mode

    I have an extended desktop through a Mini-Display Port-to-VGA connection from my Macbook Pro (OSX Mountain Lion) to an external monitor. I have the Macbook Pro screen set up as the "main screen" (with the display bar on top). But everytime I close my macbook pro, the computer goes into clamshell mode and sets the extended desktop as my "main screen" which switches my display bar. Is there anyway to tell OSX ML to always keep the Macbook Pro screen as the default and not go into clamshell mode?
    This also creates a problem when I want to physically close my computer to allow to sleep, but instead goes into clamshell mode and extends the desktop to my external display. Any ideas?

    this is from another discussion:

    Re: MacBook doesn't sleep when closing lid with external monitor attached with Lion     Oct 14, 2011 7:01 PM    (in response to admgtz) 
    I would like to offer this solution.  I have a MacBook Pro with an external monitor, and, for a year and a half both displays slept when I closed the MBPS.  This behavior stopped when I installed Lion.  They would sleep when I removed the power cord, but what a pain that would be.  The command "pmset -g assertions" gave no indication of which process ought be preventing sleep.
    I contacted Apple support, and after some searching, the guy working with me found this thread, which was flagged as an Apple-approved solution:

    Correct AnswerRe: How do I tell Lion to disable the LCD screen even when the lid is open?
    Aug 31, 2011 9:56 AM (in response to Bob_viking)
    Here's the command to make your laptop behave like it did Pre-Lion (courtesy of my friend):
    sudo nvram boot-args="iog=0x0"
    Works perfectly for me. If it screws up your system, just zap the PRAM next boot (cmd-opt-p-r) and you'll be back to the default Lion state. Or if you can still get into terminal, this command will get you back to Lion's default state as well:
    sudo nvram -d boot-args
    Enjoy!
    One snag was that I had to run it with the external monitor disabled, but it worked great!

  • Mid-2010 MacBook Pro stuck in clamshell mode?

    I asked a similar question to this earlier, but now the problem has been more consistent. I have a mid-2010 MacBook Pro that I often use with an external display, plugged in via mini-DVI to HDMI adapter. The problem is, after I've unplugged my macbook to "go mobile" and am away from my display, if I ever have to restart my computer or boot into Windows 7, my computer will think it's still in clamshell mode. The screen will stay dark, and if the lid is closed, the white light will stay on steadily, not pulsing. However, if I plug into my external display when this is happening, the external display works fine and I have a display again. When I look up my displays while connected to an external display while this is happening, my internal display isn't even listed in the system report; it's like it doesn't exist! And this is especially a problem now as I am away on a 3 week school related trip.
    I have not been able to consistently reproduce this problem. Sometimes it restarts normally, sometimes I restart it and get the gray + apple logo screen that then goes dark, and sometimes the internal display just never turns on. The problem doesn't seem to be related to an OS, as it happens when booting into Windows 7 OR mountain lion 10.8.5. I've tried resetting PRAM mutliple times as well as performing an SMC reset multiple times, and neither has helped. This even happened when I was booting into a mountain lion install USB, as I thought maybe a fresh install would help. I've seen many other forums discussing a similar issue, but none described quite like mine.
    What gives?? How can I get my macbook to restart normally? I really don't want to have to make a repair, even though it's looking like a hardware problem. My computer is one month after Apple Care has expired, and I can't afford a pricey repair as I'm a very in debt student who only has a MacBook because his school gave it to him in the first place. I would be very appreciative for any suggestions and/or help! Thanks!

    Hello thedoctor8706
    Reset your NVRAM and test to see if that resolves your issues. Typically that will resolve video, volume, startup disk selection, and kernel panic issues.

  • What refresh rates does the Macbook Pro 2011 support? (Internal Display)

    While I know you used to be able to change the refresh rate via General Settings, now you have to use an app or probably something terminal related.
    Ignoring this, I just got a new 2011 MBP when my old one couldn't be fixed and after having the display/resolution upgraded I noticed that, when scrolling webpages, there is a bit of... I dunno, ghosting or something? Nothing that indicates there is a problem with the display or card, but it's something that could probably be fixed by a stronger refresh rate.
    So my question is as the subject states. What is supported? I read 60 and 75 is typical for Apple, but I want confirmation. Remember, internal display, not external.
    Thanks!

    For some reason Displays no longer shows that information, so I don't know what it is. However, the last time I saw the information on a 2009 MBP it was 75.
    I'd think there is a utility around that might provide the info like Display Maestro 1.1.7 or SwitchResX.

  • Should I run my MacBook Pro in 64 bit mode?

    Thoughts? 

    >strange it's not offered as an option
    What is not offered?
    If you are talking about Mac options, I will GUESS that just like Windows, you have to buy/install a 64bit operating system... you can't tell a 32bit OS to run as 64bit

  • HP Mediasmart Home Server/ MacBook Pro 2011

    Hi there,
    I've recently upgraded to a 2011 Macbook pro and noticed that the Mediasmart connector software that facilitated backups of my old MacBook Pro via time machine to my HP Mediasmart Home Server (which runs Windows Home Server) no longer works. I believe this is because the 2011 Macbook pros are set to boot into the 64bit Kernel of Snow Leopard (and the HP kext is 32 bit).
    I don't want to have to replace the mediasmart - I've owned it for years and its done a good job in backing up both windows PCs and Macs and serving up media to various devices. Also, I don't want to have to run the Macbook Pro in 32 bit mode - does anyone have any suggestions here?
    Thanks

    Same situation with our new 13" 2011. You really have only 2 options:
    #1) Switch to 32 bit kernel. This should have very little impact on you.
    #2) Switch to a different time machine solution, such as time capsule.
    I don't see HP updating their driver anytime soon, as they are now out of the HomeServer business. You should be prepared for the strong possibility that when Lion comes out, that even the 32 bit kext kernel extension from HP may no longer work. in which case Time Machine may be permanently broken on the Mediasmart servers.
    So, you may want to do #1 (which you can always go back to 64 bit kernel), while waiting to see if Lion does indeed break the time machine functionality with the Mediasmart server. If it does, then you only have #2 open to you.

  • Will Remote Desktop allow me to access and use my Mac Pro 2009 from my MacBook Pro 2011?

    Own a small business, have two locations, I need to use Windows via Parallels on my Mac Pro 2009, but I am forced to spend most of my time at the other location which has a MacBook Pro 2011. Will Remote Desktop allow me to use the MacBook Pro 2011 to access the Mac Pro and use Windows via Parallels?

    If all you need is to be able to control another computer, then ARD would be overkill. If the systems have Mac OS X 10.5 or later you can use the Screen Sharing built into those versions of Mac OS X to control the system.
    Another and perhaps easier option is to use a service such as LogMeIn or TeamViewer. Either option may be significantly easier than dealing with screen sharing or ARD. 
    You'll want to confirm that any solution you choose will work with Parallels, of course. I haven't tried remote control of a system to use Parallals, so there may be special considerations there. If you don't get useful comments here, you might try Parallels' forums.
    Regards.

  • Ram upgrade for macbook pro 2011

    Hi people, i have a 2011 macbook pro with 4GB RAM ; i7 quadcore processor.   I am planning to upgrade the RAM. I dont really need it because I do not play games anymore neither do I do any video or photo editing, i just use it with xcode mainly. But my question is not whether i need it or not !  I need someone who has done this before to tell me the differences they noticed after the installation. Was there a big difference, small difference, and what was it. I know what more RAM will do. I just need to know if there is a big difference or not from 4 to 8 specificall for the macbook pro 2011. I am running Lion by the way. If someone could suggest some websites were i can buy the RAM at cheapest price that would be splendid. Thanks !!

    macsales.com
    I've bumped my ram up to 8 GB. However, I did that because I used programs like Photoshop and usually have five or more application running at the same time. If what you say is your MBP usage leave it alone you don't need it.

  • MacBook Pro 2011 Repair Extension Program for Video Issues -Feedback?

    Anybody have any feedback from the MacBook Pro 2011 Repair Extension Program for Video Issues?
    I had my early 2011 15 inch 8,2 repaired (free) under the extension program. The machine now appears to run well - but much hotter than before. The case is significantly hotter - especially at the GPU corner and the fans are constantly on moderate to high (not full). Anybody else experiencing similar changes?

  • HT3131 Display on to apple tv in closed clamshell mode?

    Hi Can anyone help me?
    When I AirPlay my MacBook pro display to my apple tv, all is fine.
    However when I close the lid, (clamshell ) with mains connected, my display drops out and turns off AirPlay on my MacBook pro?
    Any ideas please

    Yup. I have no issues using an external display in clamshell mode. It's only when I try to airplay to my apple tv while in this clamshell mode that I run into problems. So to clarify, there are 3 devices in my situation: my macbook, my external monitor, and my apple tv (which is connected to my hdtv of course, so 4 devices). Usually I just use my external monitor with my macbook closed. That works fine. But when I occasionally want to airplay to my apple tv as additional mirrored/extended monitor, I have to open up the macbook first to exit clamshell mode. Otherwise if I just go straight into airplay while still in clamshell mode, my hdtv shows a frozen image, my external monitor goes black and I have no choice but to manually turn off my macbook. Hope that makes sense. I think it would be easier if I could draw a diagram haha.

  • Do I need 2 keyboards for macbook and iMac in clamshell mode?

    Hi Experts, do I need 2 wireless keyboards to work with macbook pro connected to iMac in clamshell mode? or can the keyboard be switched from iMac to MacBook 'on the fly' (after activating TDM mode)?
    Problem is that when I activate TDM to display the MacBook screen on the iMac (used as the display only), the wireless keyboard is still connected to the iMac and can not be found by the macbook. So in clamshell mode, i.e. with a 'closed' macbook', I do not have a keyboard...
    Thanks and best regards, Chris

    Hello christoph128,
    Thanks for using Apple Support Communities.
    To get a wireless keyboard to work with multiple computers in any situation, you would first need to unpair the keyboard with the iMac, and then pair it with the MacBook Pro.  Since that's the case, it might be easier to either use a second wireless keyboard paired only with the MacBook Pro, or have a USB keyboard.

  • Will the macbook pro 13" 4GB ram be enough to run LPX ?

    Hi there,
    As you probably now know, Logic Pro X is finally out and it's time for me to update my old LP9 to this new soft.
    I'm going to buy a new mac and here is my problem : LPX needs at least 4GB RAM to run, I was wondering if my 2011 IMAC 21.5" would run it and in particular the macbook pro 13" (no retina screen) would too - cause I need a laptop and don't wanna leave my Imac.
    I'm not such a sound ingenieer but I don't wanna spend more than $1400 if I can't run LPX.
    Please give me advices
    Thanks
    Mike

    If it runs LP9 ok, and you have a core2duo processsor upwards (or in otherwords a 64 bit processor) that can run mountain lion, then yes, will run as well as LP9 in my experience on older machines.
