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.

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.

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.

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

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.

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 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

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.

27'' LED Cinema Display flickers when powering MBP and dimmed down

The 27'' LED Cinema Display flickers (backlight flickers) in the following situation:
* The display powers an MacBook Pro (e.g. later 2010).
* The MacBook Pro is fully charged (i.e. power is not used for charging).
* The MacBook Pro performs some GPU intense task (moving the mouse over the dock with magnification enabled).
* The brightness of the display is dimmed down to one of the lower settings (one or two "bars").
The problem disappears if the MBP is powered by an independent charger.
We reproduced the problem with two different MBPs (13'' and 15'') and two different displays.

Same problem here! I bought two brand new 27 inch Cinema Displays, one for work and one for my home office. Both showed the problem. I returned both, go replacement displays and both show the same problem. I am using them with a 13 inch MacBook Air late 2010. I use them with the MacBook's display lid closed and powered by the Cinema Display. The problem only occurs when the display brightness is at 1 to 5 bars. From 6 bars on everything is fine. I also noticed that the flickering is stronger when I USE the computer, i.e. dragging around windows, typing, etc. When I just look at the screen, the flickering occurs more sporadically. The flickering looks like a short switching off of the display light (a few milliseconds).
I just tried the hint suggested in this thread and indeed, when I open the lid and have the MacBook running on batteries (not powered by the Cinema Display), the flickering is gone! So it really seems to be dependent on that.
Please fix it, Apple! This is not acceptable for a premium-quality display! We have already done a good job narrowing down the conditions under which the problem occurs. You should easily be able to reproduce the issue like this:
- use a MacBook (e.g. new MacBook Air) and turn it on
- plug in all three cables provided by the 27" Cinema Display (power, DisplayPort, USB)
- close the lid of the MacBook and re-awake it with an external keyboard so the Cinema Display will be the only display in use
- wait a few hours for the Cinema Display to become warm (not sure if this is a necessary condition but it could be)
- then, use the computer under low-light conditions and ensure the brightness is at 5 bars or less
--> You will see the problem.
By the way, the recent Cinema Display firmware update (to address the audio issue) did NOT solve this problem.

Cinema display 30" power plug caught on fire

Hi everyone,
I have a 30" Apple Cinema display (A1083) purchased in 2008. Recently, it's power cable/wire came slightly unplugged from the 150w power supply while the monitor was on. The wire was still plugged in, but it was at a fairly severe angle. Spontaneously, sparks flew between the power supply and power cable/wire and fire shot out of the power supply melting the plastic around the cable. Needless to say but the monitor went dead at that moment.
I had another power supply laying around so I plugged that in to see if the power cable/wire would still work. The monitor came on for a while but then more sparks and the monitor went dead.
Apple no longer makes this monitor and apple care is expired (of course). Therefore, I figured I would fix this myself. By some miracle I found the entire set of cables on eBay and purchased them.
My question is:
Should I replace the entire set of cables, which would involve opening up the monitor? Or, should I just replace the power cable/wire at the end which would involve some soldering, etc.
Also, are there any tips, directions, pointers that anyone has for doing any of this? I found one guy online who opened up the case but that is a risky move.http://www.eliteweblabs.com/recent/cinema-display-cable-fix/
I'm upset my beautiful monitor isn't working and really need some help getting it back, if possible. What do you guys think?

If plugged into the power supply, should the Cinema Display A1081 standby light come on without being plugged into a mac

I was given an old Cinema Display A1081 a few years ago. I am trying to test it and want to know if plugged into the power supply, should the standby light come on without being plugged into a mac? I don't want to buy a DVI to mini display adapter if it isn't working. One thing I did do was plug Monitor power in and then the USB plulg into my PC laptop and my iPhone charger USB plug into the back of the monitor. I am able to charge my iPhone this way so I know that the power supply is working. But I can't tell if the monitor itself is workign as no ligths are on. (PS: I am purchasing my first Mac so I am a complete newb but very proficient with PCs) Thanks so much for your help.

Just a final question about Sleep mode - does this have any negative effects on the life or performance of the laptop? I'm so used to Shutting down the laptop each day that I worry about Sleep mode having some sort of drain on the components or something.
There are only two practical differences between Sleep and Shut Down:
1. Sleep will wake instantly, so you don't have to wait for startup.
2. Sleep will drain a new, fully charged battery after several days without being woken or plugged in. If you shut down, the battery charge lasts much longer. Obviously, if you only sleep it overnight, you'll still have plenty of battery left in the morning.
Don't sleep it more frequently than necessary, though. Frequently turning the backlight and hard drive off and on can shorten their life. Just do what's reasonable. I usually leave mine awake until I have to transport it in a bag, along with sleeping it overnight. On battery, I'll sleep it more often to preserve battery.

Power up Macbook Pro with 23" Cinema Display without opening Laptop lid?

Hi there,
I've just bought an Apple 23" Cinema display to use with my Macbook Pro.
I just have a quick question for working this setup. I'd like work with just the 23" display in use (i.e. laptop lid closed, due to desk space), but can't figure out how to turn on the Macbook Pro without opening the lid to the laptop for the power button!
This may sound like a silly question and I may be overlooking something as I've only had the setup for a hour, but it'd be a major pain in the ar*e if I had to open the laptop to turn it on every day, then close the lid again (and possibly go through the 'Are you sure you want to go into sleep mode...' process each time).
Can I avoid opening the laptop when connected to the 23" display? There is a power button on the display, but it only seems to put the Mac into sleep mode when it's already on, i.e. it didn't seem to work when I tried to use it to turn the Mac on from being off.
Thanks for any advice on this.
Ste

Power button on Apple Cinema Display 23"

I just got myself a used Apple Cinema Display and I have a quick question regarding the behavior of the power button. In the display options I selected "display power button : puts the computer to sleep or wakes it" but when I press the power button I get a popup saying "are you sure you want to shut down your computer".
The display is connected to a MacBook, running Snow Leopard. Is this a known issue I'm missing a setting somewhere?
Thanks!

Hi,
Don't worry, it's normal. Since Panther, It give you more choice. Personally, I prefer that.
