23" Cinema Power Button Does seem to work

I have a PC running windows xp and a 23" cinema display. I works great except the power button. The power button doesn't seem to function when the machine is on...meaning I can't turn my monitor on or off when in use with my machine. Once I shut down my machine the monitor stays on that ashy black screen and never completely shuts off even if I try and press the power button.
Also what does the light in the front stand for because I have had the monitor working when the light was on and off...seems a little strange.
FYI - I have an EVGA 8800GTS card and I downloaded the bios update from them already...don't know what else the problem could be.

I have a similar problem but with my Mac Pro. I have one of the older (acrylic casing, not the newer aluminum case) 23" Cinema HD Displays (made around 2002) with the power button that lights up and is touch sensitive.
Anyway, I cannot shut the monitor off manually. When I touch the light, it brightens so I know it senses my touch. But it will not respond by shutting off. My Display Preferences are set properly ("disable buttons" is unchecked). What could be the problem? I need to be able to shut the display off when not in use because (for some reason) the display awakens from sleep periodically for no apparent reason and may be on for hours unattended.
Thanks in advance for any help!

Froze on black screen and power button does not work

my sons ipod touch is stuck on a black screen when plugged into the computer got a spinning wheel and will not connect now spinning wheel will not go away the power button does not work so can not reset it manually
any suggestions would be appreciated

- iOS: Not responding or does not turn on
Neglect the reset and when it says place the iPod in recovery mode use one of thes programs
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Lenovo V570 Laptop Power Button does not work. Did I screw it up?

Hi, my Lenovo V570 keyboard recently stopped working so I took the keyboard off to reposition the cable. In the process I disconnected another cable on the motherboard (shown in the pictures below). I also cant find the black plastic piece that was holding it down.
Now not only does the keyboard not work but the power button does nothing. After research though Ifound out this laptop is notorius for having the power button go bad.
When I plug in the AC adapter I do see the battery light go on and it charges so I dont think the motherboard is bad. I
have tried every trick in the book as far as getting static out of the laptop power button (holding down power button for
certain times). I looked at the mainteneance manual for this laptop and could not figure out what the disconnected cable does. I have tried reconnecting the cable without the plastic piece but that did not work.
Is the disconnected cable responsible for this or should I order a new power button board with cable?

Hi Deziant,
Welcome to Lenovo Community!
As per the query we understood that you are facing issue with power button not working in your V570 laptop.
As per the snap shot which you have shared it looks like the black support connector is broken, you can fix this cable by using a gum, but I would suggest you to visit nearest service center to fix this issue.

i recently noticed that my original iphone power button does not work i push but nothing happens.

IBook won't start up - power button does nothing, PMU reset not helpful

Hi all - I was using my iBook earlier this morning and it just turned itself off without any warning. It was running off the battery, but had plenty of charge, and there was no 'low power' warning, so it wasn't that.
I can't get it to turn on now. Pressing the power button does nothing - no whirring, beeping, chiming or anything else. I tried resetting the PMU to no effect. No lights appear on the caps lock button. I haven't tried using the Mac OSX cd, but I'm a little afraid I won't get it back out of the slot-load drive with the way the computer is behaving.
I have it plugged in now and it seems to be charging the battery, so I don't think it's related to either power or battery issues. In fact, it seems the power and battery are the only things working! Absolutely nothing else happens. Unresponsive.
My warranty ran out in September (November now, unfortunately) so if it needs servicing I suppose it will be out of my own pocket.
Can anyone help?

iBook G4 Dual usb 14" Mac OS X (10.4.8)

Ok - good news. I've got the problem fixed.
After a call to Apple Support (called the Canadian one), and a $59 charge (worth it, in my opinion, since my warranty is expired) the gentleman on the line asked me to do a PMU reset with the SHIFT + CTRL + Option + Power combination. That's what I had tried before and it didn't work. Didn't work this time either.
Next, he had me remove the battery, unplug the computer from the adapter, and hold the power button down for 5 seconds. I put the battery back in, plugged it back in, and turned it on.
Voila. Works like a charm. Apparently, there are two ways to do a PMU reset.
Thanks everyone for looking at my thread, and thanks arnie for the responses.

HT201150 How do I configure what the Power Button does?

How do I configure my power button so hitting it does not automatically put it to sleep?
Because it is right by the delete key I am hitting it accidentally all the time. Also my cat is constantly putting my computer to sleep when I am working. Is there a config file or a hack I can use to force a dialog (Restart/Sleep/Shutdown/Cancel)?

Power button behaviourRe: after installing maverick power button does not provide options to sleep, shut-down
The first one is resolved but I can't see how. 10.9's pmset command didn't have the 'power button' setting when I looked recently, it looks like this feature was deleted to me.

CT, the behavior of the power button on Mavericks (10.9.2) is not as the note (OS X Mavericks: Using the power button - Support - Apple) describe. I have to press four or five times de power button in order to put the mac to sleep.

Kernel panic, "must restart" screen, but holding down power button does nothing! Need to wait until battery runs out???

Help! While doing workaday tasks on my 15" MacBook Pro with 10.6, I got the dreaded slowly unfolding darkened screen with the message "You need to restart your computer. Hold down the power button until it turns off." Kernel panic, I guess.
In the past, in the few times this has ever happened to me, I held down the Power button as instructed, and the Mac turned off.
HOWEVER, this time around, holding down the Power button does absolutely nothing! It doesn't make the computer turn off, no matter how long I hold it down, nor if I try holding it down in combination with other keys.
Needless to say, the OS is completely frozen otherwise, and no keyboard or trackpad actions have any effect.
And since this is the new kind of MacBook Pro -- there's no way to remove the battery!
So, is the only solution, to unplug it from the power supply and simply wait for 8 hours (or whatever) until the battery runs out of juice? Say it ain't so!
(I'm writing this on someone else's computer, needless to say.)
I NEED access to my computer's files TODAY for important work-related matters. Am I out of luck, or is there some secret way to get this darn thing turned off and restarted?

You may have to do this several times.
Saw this solution on another post about an iPad in a school environment. Might work on your iPad so you won't lose everything.

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just canceling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
~~~~~~~~~~~~~
Try it and good luck. You have nothing more to lose if it doesn't work for you.

Did you try to connect in recovery mode, as explained in this article?
If you can't update or restore your iOS device
If this does not work, get it checked by an Authorized Apple Service Provider or by Apple:

Lumia 920 Power Button and Flash Stopped Working

The power button and camera flash randomly stopped working on my Lumia 920. The phone itself still works (I can tap to wake it and use it normally) but the power button does nothing when pressed. I tried letting the battery drain completely then let it re-charge overnight to no avail. I also attempted to perform a factory reset but the issue persists. I contacted both AT&T and Nokia Support but they are no help at all.

hi mate,

I have reached out to this community as my Iphone display gone black and got the solution to keep home and power button pressed. It worked but I would like to know
1. Why it went black and is there a permanent fix for this
2.Will the IOS gets automatically updated as I feel the IOS was 5 when I got the phone in 2012 december
3.Do you suggest 7.1 for Iphone 4

1. There is no way of knowing. These things happen.
2. The iOS only gets updated when you want it to be.
3. You should always update to the latest iOS your phone will support. Apple do not write the updates to make your experience worse.

You need to restore the iPad.
Use iTunes to restore your iOS device to factory settings - Apple Support
If that will not work, you will need to use Recovery Mode to restore.

What to do now when my iPad won't turn on after I turn it off. It shows only the apple logo. I am sure it has above 70% charge as when I sync my iPad it shows necessary detail in iTunes. I have tried, HOME & POWER button, but did not work.

First try a Reset ( No Data will be Lost )
Press and hold the Sleep/Wake button and the Home button at the same time for at least Ten seconds... (But can take Longer)... until the Apple logo appears. Release the Buttons
If no joy... Try a Restore...
1: Connect the device to Your computer and open iTunes.
