Cinema display power button

I have a 20" cinema display attached to a macbook pro. I usually just hit the power button on the side to turn it off, but all of a sudden when I try to turn off the monitor, it asks me if I want to shut down the computer. Not sure what changed or how to turn off the monitor now. Any ideas?

Figured it out.
System Preferences > Displays > Display Power Button > Turns power on and off. Couldn't find it before.

Cinema Display power button doesn't sleep

I retired my older 15" Studio Display after recently purchasing a 23" Cinema Display. I loved the feature on my Studio Display that the power button would automatically put my computer to sleep. With my new Cinema display when I push the power button it brings up the Shut Down, Sleep, Restart, dialogue box instead. I changed the system prefs, and it still doesn't work.
Any suggestions?

I have the opposite problem as Michael's. Mine gives me the option to sleep, powerup JUST the diplay or do nothing. I want to be able to powerup/shutdown the whole Mac using the diplay button on the side. Checked the sys pref and nothing there. Maybe somewhere else?
Pls help. Thanks

Cinema Display Power Button Not Functional

The power button on my cinema display does nothing when pressed. The other button on the display (display preferences button) does work as expected. I have confirmed that the 'Disable power button' is not selected in the display settings panel.
The button glows brighter when I press it, but nothing else happens.
I would like to be able to start up and shut down my computer with this button since my bluetooth keyboard cannot do it, and I keep my laptop shut when it is connected to the external display.
I was just given this display, so I do not know if has ever worked.
Any ideas?

Hi Ron,
Possibly a daft question but do have either of the Cinema Display's USB or firewire cables plugged into your G4 as well as the DVI connection? This may sound obvious but I couldn't get the buttons on my 20" ACD to work until I plugged the USB connection into my Macbook.

23" HD cinema display power button with 2010 MacBook Pro

The power button on my 23" HD cinema display (clear enclosure) doesn't turn on my 2010 MacBook Pro. I don't use both screens at once much and would like to leave the laptop shut. Is there a workaround?

Thanks! I found I can also start up, close the lid (and sleep), then just click to wake the machine.

Cinema 23" Power button preference settings and Windows XP

Here is an obscure one.
I have a Mac Pro with 10.5.6 and a Bootcamp WinXP partition.
In System / Display / Preferences ~ options, I have the "Display Power Button Behavior" set to "Does Nothing".
When I boot into Windows XP, and then back to Mac OS, the "Display Power Button Behavior" is now set to "Turns the Display on and off"
I figure that there is equivalent behavior setting for the display in Windows XP that is resetting this, but have been unable to find it.
Anyone got any thoughts on how to keep the behavior of the power button as "Does Nothing" even after being in Windows?

I downloaded the most current version of WinACD, and it sort of works but does not solve the problem.
It appears that the most recent version of WinACD does not yet have the newer Apple monitors in its list of supported ones. So the control panel will say "No monitor present".
Here is a link to another discussion on this issue:
http://discussions.apple.com/thread.jspa?messageID=8967945&#8967945
So until WinACD is updated, this is a close but no cigar solution. It should work, if it was just updated to include the newer ACD monitors.

My Apple display power button is flashing short-short-long.

My Apple display power button is flashing short-short-long. I know what it means and I checked everything and everything seems fine. What can I do to ensure everything is really fine and the flashing stops. The computer and the display worked fine for over a year. It started doing it when I switched my computer off using the power button on the display. it never happened before.
thanks!

What you might try is unplugging the monitor at it s ADC connexion to the video card and the plugging it back in - all with the Mac turned on and everything working (and flashing).
I had an LCD/ADC flatscreen monitor that would dim the top half of the screen and start flashing whenever I would run Disk Warrior or Applejack or switch to a different startup drive. Simply unplugging and replugging would return it to normalcy - for days or weeks - but sooner or later.... Grew tired of waiting for it to go altogether and bought another monitor, but I tried it the other day on a spare Mac and - sure enough - it started up dim and flashing. Remedy was the same: unplug and replug the ADC connexion and it was back to normal. No idea why!
No guarantee, and no idea how long it might last, but the effort is small and the price is right.

Cinema Display Power Light Suddenly Not On & Power Button Not Responding

So, I've had major problems with my G5 which Apple diagnosed as being the board (and then the video card etc...). They gave me a $700 credit towards a new machine (I got a new MacBook Pro) but before I put the old G5 up for sale I wanted to try pulling some of the RAM to see if the problem was just faulty RAM. I pulled a gb from OWC I put in after purchasing the machine. Pressed power and I got the start-up chime which I haven't been able to get forever, AND the fans didn't go into turbo mode like it did before. BUT, my display which I had left plugged in for the last 6 months and whose power button has been continually lit up with the machine unplugged.......now won't light. What happened? Please HELP!!!

Happened to me last week and I did eveything possible to investigate if my power unit was broken, cable damaged, fuse blown etc. In the end I simply reset the PRAM and as if by magic the Cinema Disply came back. Touch wood it has been alright since. http://support.apple.com/kb/HT1379?viewlocale=en_US

23 inch LCD Cinema Display Power on?

I just got one of the older aluminum body cinema displays from a garage sale. I came home plugged it into the wall and hit the power button and nothing is happening should it be turning on and displaying something on the screen or do you have to plug it into a macbook/computer for it to power on?

I had the exact same problem and fortunately I own a second 23" display so I swapped AC adapters and it came back to life!
But the bad news is that I then bought a used adapter on ebay to replace it and that adapter died as well. Same display killed both dead adapters. I'm wondering if the display could be drawing too much power.

DVI to ADC adaptor: Display power button no longer works w/G5?

I'm looking for answers on a topic originally brought up in this thread:
http://discussions.apple.com/thread.jspa?threadID=221092&tstart=45
concerning the Studio Display's power button when attached to an ADC/DVI adapter for use on a G5.
I am having the same problem. I had previously used the monitor directly attached to an MDD G4, and the power button worked fine. Now that it's attached to the adapter, I can't power up the G5. The brightness button will open the Monitors prefpane, so I would say that it's not a problem with the overall USB system.
Otherwise things work fine, so it's not the end of the world, but I'd like some confirmation or denial of the problem just to know if there's a defect or not.
TIA
G5 Mac OS X (10.4.6)

It is working normally. ADC has extra pins to support the power button and light. DVI connectors don't have these pins, so there is no way for the DVI to ADC adapter to make the power button work.

30" Display power button

Just upgaraded my G5 with a 30" Display, however the power button the display does not start the computer as it did with my 23" display. The power button when pushed and the computer is on, it will turn off the computer, but it does not turn the G5 on anymore.
How can I get the power button on the display to not only turn the computer off, but also on??

It can't turn the computer on because it isn't powered through the computer anymore.
The power switch is only sending a command to your computer to shutdown... that isn't the same thing as actually turning it off. You could achieve the same result by selecting "Shutdown" from the Apple bar.
Unless Apple returns to the ADC connector, the days of powering on/off your computer from the display are over.

30-inch cinema display & Power Mac G4 Mirror Door

Does anyone know if it's possible to set up a Power Mac G4 to run a 30-inch aluminum cinema display? I have a G4 running a 22" apple display (clear enclosure) and want to purchase another desktop to run the 30-inch display without spending a fortune. I had it running on a G5 (June 2004) M9457LL/A but that just died, (logic board failure).

That monitor will work with a computer that has a DVI port, but you need this card to get a dual-link DVI port which is required to use it at its full capacity.

23" Cinema Display Power Question

I recently bought a 23" cinema display and a mac mini. I just received the cinema display in the mail, and plugged it in, but it won't turn on. I do not have the Mac Mini yet, it will get here on Monday, so I'm just trying to make sure the display will turn on or does it have to be connected to a computer to power on? Thanks.

It must be connected to a computer.

IPad Mini Display + Power Button Malfunctioning

HI I just got an iPad Mini (1st generation) two days ago and it was workig fine until today when I was clearing some app data in my settings, then the screen went out. I tried holding the power button to get it back, but it wouldn't work. However, I held in the home button on the bottom, and Siri still worked but I searched for something on the voice command and I couldn't bring up what it found because the display is still out. Can someone please send me options on possible ways to get the display back? Thank you

I have noticed this same exact thing with my iPad mini with Retina display. I notice it on YouTube, but it does it for only some videos consistently. there is this game called "Don't Starve" that I watch lots of let's plays for on YouTube, and the game has an over all sepia tone to it. Whenever I first start the video, some of the colors look off, but it fades sort of to where it should be. I pinch the video closed and everything looks off *outside* of the video, like there is no contrast, but it then kind of fades back to normal. Sort of weird, not exactly sure whether it is a display problem, or if it is a kind of auto adjustment feature... I notice it NOWHERE but videos. It doesn't really bug me, and I don't mind the screen fading back to where it should be after a video, (because at least the colors do go back to normal, rather than staying washed out!) but at the same time, it does concern me because I am unsure whether this is a software feature to enhance colors in video, or if it is a display problem. I have heard the retina mini does have image retention problems (for some devices only), which means that if a particular image is left on the screen for a long time, and then it suddenly changes, you can see an after effect of the previous image for a bit, which is a screen defect. Also, the iPad mini with retina display does have a lesser color gamut than other apple devices, seen easiest when comparing it with the iPad Air, it even can be seen when comparing to an iPad 3rd generation, or iPad 4th generation. I have observed this between my iPad mini with retina and the iPod touch 5th gen, iPhone 5, and this would also be seen between the iPad mini with retina and iPhone 5S, because the iPhone 5S uses the same screen as the iPhone 5.

Apple Cinema Display & Power Adapter

I just picked up a new 23" ACD, got it hooked up to my MBP. I had the power adapter box standing vertically on my desk. Anyways, While I was working on organizing the cables, SLAM!, the power adaper box tipped over onto the desk. now sitting horizontally from the 90 degree tip. Do I have anything to worry about such as internal damage to the power adapter?
Also, how come the manual said not to carry the display by the stand? But it just make more sense carrying the display by the stand, this way not having the screen itself lift that heavy-weight stand.
MacBook Pro - 15.4" Glossy , Intel Core 2 Duo 2.33GHz, 2GB RAM, 120GB HD Mac OS X (10.4.8)

My desk top is made of wood board, so it can echoes major sound from just small impact. The power adapter was standing vertically, then tips and lays flat horizontally. Sort of like a iPod tips over when it's not correctly connected into the dock.
I just shook power adapter to hear for any sound of any internal components broken off. Turned out no sound but a tiny bit of stiff rattling. Though it's still function, I'm still paranoid and worried.
As for carrying the ACD, Dave you made a good point, I dont really think it'll hurt if holding it by the stand upright position, which I did. The manual probably meant not to hold it by the stand upside down or in a 90 degress position, which increases the chance of the screen knock into something. The stand secures the screen and it's designed to hold the weight of the screen, I don't see why carrying this display by the stand in a upright position will be a issue.

Power on from 30" CD power button

My old mac would power on from it's Cinema Display power button. My new Mac Pro won't. The CPU is in a gear closet, so this is very inconvenient. Is this normal? Is there any way to remotely power on a Mac Pro? I've tried a USB keyboard with power button but no dice...

There were devices for remotely powering on PowerMacs but I don't recall who made them and I don't know if they'll work with the Mac Pro. You might consider just putting your Mac Pro to sleep instead of shutting it down.
