Cinema Display and MacBook Pro - Power Button won't work

I have been using a 20" Apple Cinema Display (plastic model) with a 17" Powerbook and never had a problem. Recently I acquired a 15" MacBook Pro and it's like the power button on the display has no use at all. The only way to turn on the computer is opening the computer lid, turning it on and then closing it. The display also won't shutdown the computer, although the power button light reacts to the touch. The funny thing is that the display settings button work fine. Does anyone has a clue?

Malcolm, thank you for the answer! But I still don't understand why my new MacBook Pro, having exactly the same connector as my older Powerbook had, won't behave the same way? I'm still using the same DVI to ADC adapter, I'm wondering if the new Macbooks maybe have some PIN assignment disabled on its DVI connector. And anyway, shouldn't the power button be able to at least shut down the computer, as long as pressing it would just open the shut down dialog box?

  • I just installed iOS 6.1.5 and now my power button won't work

  • Dual Display - help with Cinema Display for MacBook Pro where MB won't detect displays.

    I just got a Cinema Display (a1081 20") ("CD") off eBay to use as a dual screen with my Macbook Pro OS X 10.6.8 ("MB"). However, I can't get MB to recognize CD! I've tried power cycling both the MB and the CD with and without USB cord connected. MB won't recognize CD display in any situation. However, it is recognized in some capacity although I can't use dual display because the CD power button triggers MB to ask me if I want to restart, shutdown, or cancel.
    Any help is appreciated!!

    Have you tried smc and pram resets?
    Try Detect Displays in the Displays preference pane.
    Does the Displays preference pane Arrangement show two screens?  If so do click gather windows and check the resolution setting of the new screen.

  • Apple Aluminum Keyboard and 23" cinema Display and MacBook Pro??

    Hello there
    I have just purchased an Apple Aluminum Keyboard and have and MacBook Pro with and 23" cinema display, and if i try to connect the keyboard to my cinema display via USB the keyboard don't work.
    i have an Apple mighty mouse that works fine wen connected to the USB port on the display...
    why is it not working...

    have you tried a different USB port on the ACD? Maybe the one you used was defective? I run a 7-port bus off one of the USB ports for all my hardware. OTOH, I do use bluetooth mouse and keyboard!

  • Connecting a 20" Cinema Display and MacBook Pro 4,1

    I admit I bought a cinema display from a co-worker because I thought it'd be nice to have a larger screen to attach to my MacBook pro 4,1. However, the monitor has a flat connector that doesn't seem to fit anywhere on my laptop. Is there some sort of adapter I can get? I've seen similar questions posted, but none with my exact specs.
    Or, should I just sell the monitor back to him or someone else?

    It says: Model Name: MacBook Pro
    Model Identifier: MacBookPro4,1
    Processor Name: Intel Core 2 Duo
    Maybe I'm a total dork. on the right side, I see, back to front: a monitor adaptor (which i use at work to plug in a Dell), an Ethernet port, a square-ish port with a firewire symbol, another firewire (with the 'dog-eared' edge), a USB, and then a tiny tiny rounded little hole that doesn't appear to go to anything. On the other side, I have the magnetic power cord, another USB, and two small round holes - one for DVI?, one for headphones.
    This is where I get a little confused. The Cinema Display looks like the one in the bottom right of this page: http://en.wikipedia.org/wiki/Mini_DisplayPort, and the little round port on the left of my laptop has the same symbol, but is the size of the headphone port.
    Do I need some adapter from the squareish one to the little round one?

  • Weird color tint w/Cinema Display and MacBook Pro

    I just purchased a new MBP a few days ago and have it connected to my 20" Cinema Display. Here's what I'm doing to get the display ONLY on the Cinema Display:
    1.)Start MBP with display connected
    2.)Put MBP to sleep and close the lid
    3.)Wake the MBP with the attached keyboard or mouse
    This then turns off the MBP's display and the picture appears on the Cinema Display. However, when the image is first displayed on the Cinema Display, it has this very strange brownish/orange tint to it for about 2-3 seconds. It then changes back to the correct color.
    Is this normal? If so, why does it do this? Anyone else's Cinema Display<-->MBP combo do this?
    Thanks!

  • I have a 25" Apple Cinema Display and Macbook Pro. Want to use iSight camera on ACD.

    When I use Skype or Google+ Hangout, I'm not able to use the built-in camera on the ACD. Is there a preference to switch camera from Macbook Pro to ACD?

    I don't know about Google+ but in Skype's Preferences, there's an Audio/Video tab and within that window there's a popup menu for the camera.  Does that allow you to select the ACD?

  • My MacBook pro's power button won't work.

    So my MacBook pros power button wouldn't work, there fore I couldn't switch the notebook off, which I need to do to try and get access to my houses wifi, which strangely wouldn't connect although would t my iPad and iPhone. So I turned the laptop off through the keyboard short cut and now when I try to turn it back on, the button won't work. The laptop was running perfectly fine (appart from the Internet connection) it was charging great and should be duly charged at the minute, i just can't find a way to turn it om, is there anyway other than the button? And what could be wrong with the button itself, as I'm clueless.

    System Preference > Trackpad > Point & Click > Secondary click
    Make sure that "Secondary click" is enabled.
    Click the  black downward arrow to get the pop-up and pick your choice.
    Best.

  • Sound Switches Between Thunderbolt Display and MacBook Pro

    I have an Apple Thunderbolt display and MacBook Pro set-up with dual screens. I have an iPhone plugged into a dock that runs to the display. When I have music playing out of the display and I disconnect my iPhone, it switches the sound to the MacBook Pro.
    1. How do I stop this from happening?
    2. If I can't stop it from happening, how do I move the sound from the MacBook Pro back to the display?
    There doesn't seem to be any options within Preferences/Sound to change it back.
    Thank you.

    I've a Spyder4Elite that I use on both my Thunderbolt Display and on my MBP - and, while both are calibrated, they don't - and cannot - 'match' one another, no matter how hard I try.
    I suspect that you're running up against the same wall? Different technologies in different displays. I doubt that you'll ever get a perfect match: mine are just 'good enough'.

  • HT4245 my iMessage on my macbook pro mountain lion won't work.

    this is a very frustrating problem
    my iMessage on my macbook pro mountain lion won't work.
    it keeps on saying that ive entered the wrong passcode.
    i even have my firewall turned off
    plz help

    Ok...
    So I bought my MacBook Pro second hand, and it came with no installation discs, but I got Mountain Lion and had it installed and decided to back it up to a disc in case of this scenario. I followed some instructions to make a bootable disc and used it to install a fresh copy of Mountain Lion back when I first got it.
    My problem is that without the boot partition of my MacBook's hard drive it doesn't seem to want to boot the disc.
    Since I didn't want to buy a disc and I don't have another MacBook or know anyone near me that does, I decided to download a hackintosh iso and use it along with my other laptop to install iPC 10.5.6....this installed successfully and my hopes were that my MacBook would be able to boot it, so I reinstalled my MacBook's hard drive and to my surprise it booted, although not normally. Since it is hackintosh it has some rewritten boot features so it's not a true OSX, but it is fully functional. Since I finally had OSX booted I figured I was in the clear and would be able to install Mountain Lion from this, but then I found out that you have to have Snow Leopard 10.6.8 or later in order to install Mountain Lion.
    Now I'm stuck with a hactintosh version of Lion and still no way to get back to Mountain Lion, is there anything I can do now that I have a functional OSX installation?

  • Ipod power button won't work

    As of late, my power button is acting weird.  Either when you press the power button it won't turn on.. or it will.. Sometimes it works sometimes it doesn't..
    To get it to turn off if the power button won't work, I'll just drain the battery.  Anybody know anything to help?

    That's a hardware problem.  Apple doesn't repair it.  If there is no sign of abuse (don't try to fix it yourself), they replace it with a refurbished unit.  The fixed-price for non-warranty replacements can be found here.

  • Macbook and Macbook Pro Power Adapters

    Is it safe to use a Macbook Pro power adapter in a Macbook and vice versa?
    I have just noticed that the MBP's adapter is 85 watts and the MB's is 60 watts. I hadn't realised they were different.
    My wife and I share each others adapters all the time (she has a Macbook). Will this be damaging either of the laptops?

    Shouldn't cause any problems. The main issue will be that the 60w adapter won't provide enough juice to both charge the MBP battery and run it if there is much of a load so I'd avoid using the 60w on the MBP for anything other than charging the battery whilst not using the machine - sudden power shortage could be painful for the machine.
    Best of luck.

  • 27" Cinema Display & 17" Macbook Pro not calibrating correctly

    I've had my 17" macbook pro hooked up to a 27" viewsonic LCD monitor for about a year.  The colors have never been right, as many times that I tried calabrating them through the built in Apple calabration system, or if I use my X-rite I1Disply 2.  Today, I bit the bullet and bought the 27" Apple Cinema Display and nothing changed, the colors are still off.  The monitor looks slightly warmer than the laptop. I'm a wedding photographer, so it can be frustrating not being able to use the bigger monitor to edit.  Thanks in advance for you help...

    Would changing the contrast help?  I don't know, I'm just asking, because there is a contrast control in the Universal Access preferences Seeing tab.

  • Installation of 27" cinema display with macbook pro silver key and bootcamp

    For everyone out there who may be interested in using the new 27" cinema display with an older Macbook Pro Intel with silver keys and bootcamp.
    What is needed:
    1. Apple 27" cinema display.
    2. Macbook pro Intel silver key model
    3. Altona Dual Link DVI to Mini DisplayPort Converter (Model AT-DP400)
    4. Bootcamp 3.1 drivers from Mac OSX Snow Leopard V10.6.3(retail)
    Procedure:
    1. Update your display software on the Mac OS side. Apple has posted an update on their software downloads page, "LED Cinema Display Software Update 1.0" After doing so, make sure that the 27" CinDisp is operating correctly and you can change the brightness from the system settings.
    2. On the Windows side, install the bootcamp 3.1 drivers. These are on the Snow Leopard distribution CD. However, there is a bug in the .msi installer that causes the installation to go into an endless loop. This must be resolved during the installation of the drivers. The following article discribes how to do this:
    http://discussions.apple.com/thread.jspa?threadID=2305631&tstart=0
    3. After you have successfully installed the bootcamp 3.1 drivers, then install Apple's bootcamp update: "Apple Magic Trackpad and 27-inch LED Cinema Display Update for Windows 32 bit".
    Good luck, it works!

    I have the same MBP and recently bought a 23" cinema display on Craigslist for $140.  It works great.  I had a display port to DVI adapter and it worked fine.  Built a stand to hold the laptop vertically so it's out of the way.  Don't know about older displays but anything with DVI should work fine.
    The screen size and resolution are great for photo editing.  I now have the best of both worlds, a display that rivals my wife's iMac and portability.
