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...
Recently my phone overheated, after this spontaneous heat was over my power/unlock button has become quite unresponsive. It works when it wants to and i am in fear that i have fried my phone and or the power button
Is it possible to turn the search button or the Volume buttons into the power buttons until i can replace the phone and or power button?
Thanks!

I must be searching for the wrong things. What is the button combination to force a shutdown on the Note Pro? Thanks.

Press and hold:
Power only - power off
Power + vol up - recovery
Power + vol dn - download mode.
Is this what you are needing?

Those were what I was expecting. But the power+vol combinations aren't doing anything on mine. It is a Verizon LTE version, but I wouldn't think that would make a difference?
They should work . . . best way IMO is to just do a shutdown from within the OS, then while the tablet's off press and hold a vol/home combo prior to pressing and holding the power button. Once the model number splash screen appears let go of power first while holding the other two . . hold the other two for a second or so and then let go.

Ok, this is really silly, but I don't find any way from the Note Pro's OS to do a power down, other than the popup from holding the power button?
(Sorry, bit of background, this all started from a problem that my power button was only working to wake the tablet, but after that, had no effect whatsoever. After mucho playing, for no apparent reason, finally the popup menu came up, I did a restart, and it's been 100% since than. But it has left me worried how to do a shutdown if the power button isn't working. No pulling the batteries on these things.)

Correct, when booted into android OS a momentary holding of the power button will bring up the power menu one option within which will be to power off. This is typical of many android devices.
Are you sure your power button is operating normally?
I have read elsewhere of a user having issue with his power button not feeling right (less travel than anticipated without much tactile feedback when depressed indicating possible defect).
I would like to add for clarity that there is no force shutdown via hardware button, only force reboot. Holding power down for several seconds will force a full reboot. Holding it down briefly to get the power menu gets the power off option in the menu to fully turn the tablet off. If your tablet reboots after this option is chosen then something is wrong.

No, because after returning to working fine yesterday it is acting up again. Not a hardware problem - if the tablet is off, the button will always work to wake it up. But once again, it is now not being responded to when the tablet is awake - either a quick push, a long push, or in combination with the other buttons.
It seems like this is a software problem, either driver or app, since mechanically the button works every time to wake up the tablet. And, of course, I can't do a shutdown or reboot to see if that clears it, because its not responding to the power button. Can't remap the power button because no root available on the Verizon LTE model. Frustrating.

I would take it back to Verizon. IMO software shouldn't interfere with a long depress forcing a reboot. That function is fundamental. This still sounds to me like a possible hardware issue where a long press is not identified as such (intermittent connection in the button).

But a short press also doesn't work when the tablet is on, but does work when the tablet is off. But then it clears up, and always works properly for awhile.
Unfortunately, unlike phones, taking out the battery isn't an alternative option...
I dunno what to tell you. Without root I don't see how any software you have installed on the tablet would have changed anything, and without the ability to get into download mode I'm not sure there's a way for you to do a factory reset that will fix the issue (if it is indeed a software one). I hope someone else chimes in that can help. My suggestion to take it in to Verizon still stands though.
Good luck!
Hello there,
I have a problem with my Galaxy S3. The Power Button is damaged, and doesn't work how it should. Sometimes there is no reaction after pushing the button, or it sticks fast. And there is the Problem, when pressing the Power Button for 8 Seconds, the Phone reboots -.-
So sometimes while just using my phone it reboots itself because of the damaged power button. I found one kind of solution, with Root Explorer I changed the functions of the Keys Home Button und Power Button with the files /system/usr/keylayout/gpio-keys.kl and the other one qwerty.kl
I changed just the Names HOME and POWER, now my Power Button = Home Button, and my Home Button = Power Button.
And here is the Problem:
There is still the Function after pressing the Power Button for 8 Seconds, it reboots. How can I deactivate this Function? Where can I find it, or is there another Solution for this Problem?
I bought my Phone from a friend without a bill, and its rooted + CyanogenMod. So if someone asks... I can not let it get repaired by Samsung.
Thanks for your help and sorry for my bad english.
Hi,
Go to a service center. You need it fixed and it's not that expensive. Or find the parts and a YouTube guide and fix it yourself. Not much you can do otherwise.
Good luck!
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.
