Macbook Air hangs when connected to an external main monitor

I have a Macbook Air the I connect to an external monitor as a main monitor using an HDMI to DVI cable. The configuration is equivalent to the LED display from Apple. The system works correctly while I am using it, but when it gets sleep, the system is unable recognize the external mouse/keyboard, and it hangs. I have disconnected the external monitor, disconnected and reconnected the USB and nothing works. The only way to recover the computer is to halt it using the power button and power it on another time.
I have also put the computer to not sleep if it is connected to mains. It still sleeps.
Does any one know how to solve this problem?

I do not know.
What I know is that if I suspend the machine, it recovers correctly, but if it suspends itself, it is not able to return to normal activity. It seems like it is unable to remember that it has to use the external monitor and peripherals in the second case.

  • MacBook Air freezes when connected to the Internet. (LAN and WiFi)

    I have a MacBook Air A1304 running Mac OS X 10.6.8.
    When it connects to the AirLive Duo router set as Client + AP (bridges the wifi signal from the DSL), it freezes up. 
    Wifi works fine with the iPad.  I tried the wifi and LAN and I get the same results. I don't even have to be surfing, just being connected to the Internet will freezes the whole MBA after about a minute.
    AirLive tested their router with their MacBook for two days but didn't have any problem. I run the latest firmware for the router too.

  • Why does my macbook air work when connected to HDMI but not my iMac

    Hi. I have an HDTV, an HDMI cord, and a HDMI -> thundebolt adapter. I plug this in to my 2013 MBA and it works fine, but when I plug it into my iMac, nothing happens.
    Why?
    Do I need a DVI -> HDMI adapter (I already have one for my dual monitor, so it would only be 5$ for the adapter.
    Thanks for the help .

  • Macbook air 2011 model to connect to an external 1080p monitor QUESTION

    i have the July 2011 Macbook Air 13". I would like to connect it to a 1080p lcd monitor or an hdtv.
    Can anyone recommend a decent model? i do not want to spend more than $300 and would prefer either a 27" or 32"
    When connected to an external monitor, will i get higher screen resolutions instead of my 1440x900 that i have on my air?

    Its going to be tough to get a "decent" model LCD monitor of that size for less than $300.  A decent model of that size will START at around $300.  That being said, your resolution will depend on what mode you set the monitor at from your Air.  If you set the mode as Mirrored, you will only get the 1440X900 on the Air, but if you set it at Extended Desktop, it should fully fill the monitor.  Also, you can set the external monitor to be the MAIN monitor with the computer operating with the display closed to get the full screen at 1080, but then you will need an external keyboard and mouse.

  • I have connected my new Macbook Air to my existing Samsung large external monitor with a VGA adaptor but I can't get the full mac desktop to display. No icons but then websites are coming up. Help!

    I have connected my new Macbook Air to my existing Samsung large external monitor with a VGA adaptor but I can't get the full mac desktop to display. No icons but then websites are coming up. Help!  Further info:  I am a complete newbie to Mac.  Had three macs prior to 2000 then four PCs.  Just come back and struggling a bit with the unfamiliarity. On my old PC laptop I could simply switch from the laptop screen to the large external monitor (and back)  with the F4 function key.  While I can get the background image from my MBA to display, that's it.  Until I noticed on the far left of the external monitor, the very edge of one of the web pages I was on.  So Idragged it over to display in the centre.  But that's all that's there.  And now I have gone out of those web pages but they are still displaying on the monitor.  There is some wierd disconnect.  I'm sure it is just a setting thing.  Will keep searching for answer but any advice welcome!

    Your dsplay is getting extended onto the external monitor. Chcnage the setting to duplicate it or only display on the external monitor and you should be fine,
    Let me know if this worked for you.

    If you are using Ethernet to connect the two computers, then enable File Sharing on the MBP. Select the MBP's Desktop drive icon. Press COMMAND-I to open the Get Info window, check the box labeled "Shared Folder." You should then be able to mount the MBP's shared drive on the MBA's Desktop and browse to your heart's content.

  • My Macbook Pro 15-inch with retina display crashes sometimes when connected to an external monitor

    My almost-new Macbook Pro 15-inch with retina display goes black and shuts down sometimes when connected to my external monitor. (The first time it did this was when connected to a projector.) They have replaced the motherboard but it still happens sometimes. The computer and monitor both come back on after a few seconds.

  • My MacBook Air has problems connecting to a saved network when I first open it.

    My MacBook Air has problems connecting to a saved network when I first open it. When it idles, the connection gets lost and even clicking on the network won't connect it. Then I have to turn off wireless and turn it back on for it to connect. My boyfriend's MacBook Pro does not have this same problem and this problem started maybe 2 months ago and nothing about our internet or router has changed, and its only my computer having the problem. Its a 2013 MacBook Air and my softward is: OS X 10.9.1 (13B42). Please help!

    Hello, nheredia05. 
    Thank you for visiting Apple Support Communities. 
    There are a couple steps that I could recommend trying.  Power cycle the router and test to see if the behavior persists.  Next, try an remove this prefered network from your list and then add it back again.  Make sure all firmware updates have been processed on the router side and the settings have been optimized for performance.  If the issue still persists try the steps in the second article.

  • How do I connect my MacBook Air bought sep13 to a Benq GL2450? monitor?

    How do I connect my MacBook Air bought sep13 to a Benq GL2450? monitor?

    External screens are designed to work as extended displays for your computer's display. It means that menu bars and desktop icons won't appear, and you will only see windows if you drag them to the right part of the computer's display.
    To change this, you have to activate video mirroring > http://support.apple.com/kb/HT5019

  • My new Macbook air won't connect to my Vizio HDTV.

    My new Macbook Air won't connect to my Vizio VO32LF HDTV.  I bought a mini-displayport to HDMI cable to connect the two.  When I connect the cable, and switch to the appropriate HDMI input on the TV, my Macbook Air screen will flash blue for a second, and then return to normal.  The TV reports it's unable to find a signal.  I use the HDTV as my primary monitor, so I'd really appreciate some help on getting the two to place nicely together!

    Cp,
    Thanks for the reply. However, it appears that the issue is not with the hotspot, but with the network settings in the MacBook Air as every other device I have (including non-Apple devices) will connect to the iPhone hotspot. Another symptom is that my MacBook Air can find my iMac (and other network devices) on my wireless network, but the iMac can't find the MacBook Air.

  • MacBook Air no longer connecting to monitor via HDMI after recent update.

    Hi all,
    My MacBook air typically has no issues connecting to my external ASUS monitor via Thunderbol-HDMI port. However, after the recent Mavericks OSX update that was pushed a couple days ago, my monitor says that there is no signal. My MacBook air screen flickers slightly once connected (typical behavior, as it begins to mirror the screen on a scaled resolution shortly there after) but then nothing happens.
    How can I fix this?
    Thank you!

    Welcome to Apple Discussions
    Try System Preferences->Energy Saver:Automatic graphics switching (Deselect the checkbox).
    If that doesn't work you might try changing the resolution and refresh rate for the monitor in System Preferences->Displays, or downloading an app called SwitchResX (shareware) and lowered the resolution just slightly .
    One other solution if possible - restore to time before update from backup.

  • I have an 11" MacBook Air.  When I plug in my VGA adapter to my Thunderbolt port, the computer doesn't recognize it ... unless I reboot the computer.  Is there another way to get the computer to recognize the adapter?  (It works with my MacBook Pro)

    Thanks for the useful feedback, Knucklesmac. I agree. I must have blown something on the logic board -- because I had a faulty old KVM switch that would not switch between computers without some nasty hot-plugging/unplugging the VGA video cables. (wince!). It's like when Dizzy Dean ruined his arm because a line drive hit him in the foot and he readjusted his mechanics around the injury. I take the blame because this has been a great computer, and does not deserve any blame.
    If it will help anyone else reading this thread, C2G (née Cables to Go) has some interesting ideas for still getting external video out of this computer:
    -USB-to-VGA
    http://www.cablestogo.com/product/30545
    -Convert s-video or composite video signals to high resolution VGA
    http://www.cablestogo.com/product/40971
    The price range is $75-$85, which doesn't make horse sense to me for such an old computer -- which has a lot of life in it anyway, because its own 15" monitor is not chopped liver.
