I own a Samsung Captivate and I was running CM7. Randomly my Power Button wouldn't unlock or lock the phone. I flashed to stock and still no avail. Also my phone turns on as soon as I insert the battery. Please help
Power button could be bad. If still under warranty, get att our Samsung to replace it.
I'm not under warranty though :/
This just happened to mine while doing the same thing. I took my power button plastic piece out, and messed around with the actual button, and it fixed it, but that's just for me.
I am having the same problem right now as well. I used this to remap a power button to my volume down key, but still cant get my power button to do anything.

If I feel bold I might try opening it up and fiddlying with the hardware button as welll...

My power button does not work at all. It doesn't put the phone to sleep nor can it wake it up. Holding it down doesn't even give me an option to shut it down and presumably it can't turn the phone on either.
So basically I think I just wore the button down. Now in spite of that, is there a way to reflash a new ROM without being able to turn it on using the button? I mean, if I remember the procedure correction, you just have to turn it off to take the sim card out and to put it back in. Can I forgo this step?
I mean, I am just sliding out my keyboard to wake it up but I fear if my battery ever fully runs down.
Try to Hard reset your device..
To perform a hard reset
1. Pull out the stylus.
2. With the device turned on, press and hold the VOLUME DOWN and ENTER buttons, then press the RESET button with the stylus tip.
3. Release the RESET button, but continue pressing the VOLUME DOWN and ENTER buttons until you see this message on the screen:
This operation will delete all your personal data, and reset all settings to manufacturer default. Press VolUp to restore manufacturer default, or press other keys to cancel.
4. Release the VOLUME DOWN and ENTER buttons, then press the VOLUME UP button to perform the hard reset, or press any other button to cancel the reset.
Yup, didn't work. Am I boned if my phone ever turns off? Jeez, and I just received that extra battery too.
Is there a way to remap the sleep button to the PTT key?
you dont have to pull out the stylus or have the device on to do a hard reset. just turn on the device and immediately hit volume down and center. once the screen lights up you can let go then wait for the reset message and press volume up.
anyways, if you have a att fuze, take it in, its under warrenty, theyll replace it. in any case you need it fixed. you cant live your live hoping your battery will never die. you cant turn it on or flash a new rom or anything without a working power button. if you dont have att im sure you can call htc and tell them you want it fixed and theyll mail you the supplies to get it shipped. just hope you can live without it for a couple days. its youre only options if you want it working.
I came back here all excited to post that it suddenly started working but it is back to the way it was.
The phone is really old so it's just of warranty and I don't think it is worth it to have it fixed when so many other problems are wrong with it. I guess it's time to be looking at new phones.
And now the power button is working. This phone just boggles the mind, people. I'm sure it'll stop working in a couple of hours though. Does anyone have any ideas what could be causing this? Maybe a short due to rain or something? Worn down contacts?
Same power button over here.
Sorry for reply on an old article but Google won't help me. I'm havin' the same problem. Na responds on the power button neither can i do a hard reset.
Anyone has a sollution. Phone is out of warranty ...
Is it a hadware problem of something with the software. Still has the (updated) stock rom. I've tried to reflash it with this latest rom but this didn't solved the problem.
Solved (for the time being..) The button seemed to be stuck. With my fingernail I managed to 'lift' it.
The other day my infuse's power button started dying, apparently i have bad luck with samsung buttons as my captivate's power button broke on me too. It started out just randomly lighting up as if it were touched, then moved on to rebooting, and now it just continuously plays the samsung logo over and over again, even when trying to go into recovery mode. Even with the plastic phone shell off, the problem persisted, so the plastic power button itself i know is not the issue.
I'm wondering if anyone knows of any possible way to render the power button useless, and remap one of the volume keys or something as the power key instead.
Any suggestions would be GREATLY appreciated, I really don't want to have to pay samsung to repair it.
There's an app called button remapper or something along those lines. But I believe it will kill any other function that the volume button does, like volume control. If you don't use it for that purpose, then try it out.

So my GS3 has been fine up until about an hour ago. It looks like the power button is somehow stuck to "on," as in, the button acts like it's always being pressed.
The physical button isn't stuck down. It clicks just fine. Here is my problem, I'm rooted with a custom recovery. I can't get into download mode to odin back to stock. whenever I press vol up to go into download mode it immediately reboots or boots the phone up.
Am I completely hosed here? If I take the battery out and put it back in it immediately powers up(hence why the power button is stuck in "on"). Also, another factor proving that the power button is always triggered as if held down is I can pop the battery in and just press vol down and home and it will launch into the initial download mode screen(press vol up to continue).
EDIT: I want to odin back to stock in order to send it in for warranty replacement.

I literally had the exact same problem yesterday and today. What I did was unscrewed the little screws holding the back plate on and this gave me more access to the power button. I popped the plastic cover of the power button off with my fingernail and proceeded to lightly press and jiggle it. This allowed for it to work temporarily which gave me time to odin back to stock and now my phone is being replaced under warranty.
Best of luck!
Have you tried massaging the button back and forth to try to loosen it? It might be easier than removing the screws to access it more. (If it works)
Literally just started happening to me yesterday also. Not quite to that extent, it randomly clicks on and the power menu jumps up over everything I do, but maybe I should return to stock before it does get stuck down. Either of you use the ZeroLemon 7000 ma/h battery and case?
SO I looked around and diddn't see my particular issue posted already.
My S III has a broken power button: when I gently tap the power button the phone locks, then turns back on, and then shows the power off options as it would if I held the power button down. I dissasembled the phone and tried using the hardware button itself (without the actual plastic button over it) and I had the same issues.
I am broke and really want CM on this phone. As you would expect, If I even try to get into download mode to flash CWM Recovery, the power button forces the device to restart.
I was wondering if anyone knew of a way that I could install CyanogenMod without the use of this button or maybe any other way.
All help is appreciated,
Thanks!
Edit: If it helps, I just noticed that i'm on 4.3. Is there even a way to unlock or roll back the bootloader at this point?
Thanks again.
Hi
My Nexus 5 has entered into (what I believe to be) a hardware bootloop due to a faulty power button switch. I will look into getting it fixed locally but am currently wondering if there's a way to get the phone on (disabling the power button in some way?) in order that I can recover data from the built in storage.
I realise this is unlikely as it would involve some kind of invasive hardware trick.
On the basis that my phone may never turn back on, is there any way to extract data from the built in storage at all?
try smacking it into table below the power button. Seriously If it wont help, just pop off the back cover and using a knife or something "brake" the button, and insert the usb cable while holding volume down button,. then send "fastboot reboot" command. You are going to fix the button anyway, so breaking it wont matter
I had same problem. I took phone apart and soaked button side in pure alcohol. And then some tapping and pushing the button and it started to work.
The power button getting stuck has happened a few times to me. I literally just find a wood table and give a few stiff taps to the top corner of the phone (power button facing down). Always does the trick for me.

Thanks, but I've had no luck with this 'solution'. I have tried tactically hitting my device but no luck. Have also smacked it down out of anger and no luck either.
I think there are two distinct power button failures. One where the button still works but sticks and can be unstuck (I had this on my first Nexus 5 and it was replaced by Google out of warranty) and another where the power button module fails and becomes 'always on' needing replaced.
