I have messed up with my mobile and power button is not working properly. Even if I just touch the button, power menu appears and my restarts. Some service guys said there is a problem with the motherboard.
I found on this THREAD to map hardware keys for android phone. I did install Buttonremapper but power button option is not available for mapping.
Are there any other applications available?
I am also planning to sell this phone. Anybody interested? :angel:
If it's a loose contact, it can b solved by gently hitting the phone's side on a table/wall.

I had given that mobile for repair. The first time they repaired and later replaced the button itself but the problem persisted. Service center person mentioned there's a problem with the motherboard. Adequate power supply is reaching for the power button. It is even damaging the phone battery. I have already replaced my phone battery twice.
Hi, I have a problem with a P5113. I plugged an audio jack into it to listen to music on some speakers and the tablet instantly shut off and would not power back on. I have tried the vol+ and power, vol- and power, and power while touching the screen methods and nothing works. I aslo opened it up and disconnected the battery for hours and tried to boot (with and without battery connected) with no dice. The only sign of life is when I first press the power button, the screen backlight flashes for a split second. Also, when I plugged it into my computer via USB cord without battery attached, the backlight kept flickering at an interval while my computer kept trying to install it, like it was repeatedly trying to power up, but couldn't. I tested the fuse near the battery socket on the motherboard and it's good. Short of completely replacing the motherboard, I was wondering if anyone has a solution or suggestion that I haven't tried yet. I'm thinking a shorted capacitor, but my skills with identifying and testing SMD's is lacking. My main concern is the files that are stored on the memory of the motherboard since a replacement only costs $50. Any help would be greatly appreciated and any additional information will be gladly provided. Thank you.
I recently purchased the Nexus 5 which has been a blessing up until now when it decided to shut off the screen and freeze or turn off without a way to power up again (there's no way to tell which).
I've tried everything I can think of to reboot the device including:
•Holding the power button
•Holding power button+volume up
•Holding power button+volume down
•Holding power button and both volume keys
•The above while connected to the charger
•Letting it charge for a\an minute\hour\multiple hours then repeating the above steps
Here's all the info I have:
•The phone was in a normal state being used as it usually would before the incident
•The battery level was around 80%
•Right before the incident the speaker used to play back music, video, and apparently allows you to use your voice to input text stopped working.
•Right after the incident the temperature began to rise exponentially (as if the phone was still on but frozen) before cooling and heating again randomly.
Again anyone's input or advice\help will be greatly appreciated! Thank you for your time and of course any suggestions will do so don't be shy.

Yikes. I'd RMA. Sounds like you got a faulty one.
Sent from my Nexus 5 using xda app-developers app
Unfortunately because Google requires another $350 authorization hold before they send a replacement I can not RMA at the moment.
If no button combination turns it on for you, even with the charger...
I think your next best bets are to:
A: Let it DIE overnight.
or B: Let it charge overnight and come to it when you wake up.
If that doesn't work, maybe give Google a good ol' ring?
Those last few words before death on your phone are kind of troubling sounding. Maybe something when haywire?
Was it a Stock Nexus 5?
All of the button combinations did manage to finally turn off the device. So no letting the battery die anytime soon.
It was a stock rooted android 4.4 KitKat.
I didn't drop it or get it wet or anything, it was just sitting on my desk and it randomly shut off. I've tried shutting it off and on again but it just comes back to the google screen where it sits frozen for about 30ish+ minutes before it shuts off, I can't turn it off otherwise, if I try turning it off it just turns itself back on so I can't shut it off. Is there anything I can do to save my data (or even better, fix my phone) or am I screwed? I also don't have USB Debugging turned on so I can't get stuff back that way either. My phone is not rooted and running stock android 5.1.? (Don't remember my exact version but I think I've missed the last 2 minor updates)

Sounds like your power button failed, like mine

I has an issue with it a few months ago with the power button but it was stuck in a constant bootloop (I later found out that the power button was physically stuck, and a few hard flicks fixed it) , now it's just frozen on the google logo for 30-40ish minutes and then it shuts off by itself. Could that still be an issue with the power button?

Yeah, my LG warranty expired so I found a seller on eBay doing it for 25$ (replacing the switch inside)

I'm kinda confused on how this is the power button. On a working Nexus 5, if you hold the power button down the phone just continually resets, now it freezes on bootup and doesn't shut off for a really long time. Then after it shuts off, you have to manually turn it back on (then it just freezes again). I feel like this is could be a software issue but I might be wrong.
I've seen posts saying to reset the cache partition. Will that wipe the data on my phone?
I went into recovery mode (Does this mean the power button is fine, since I could successfully navigate the boot menu) and tried to format the cache and it says it was wiping /cache for about 20 minutes then it shut off and the notification light started blinking red and the phone wouldn't turn on at all when I held the power button. I assumed this meant the battery died during the cache wipe (Is that what the red light means, if so is that bad?) so I plugged the phone in. After about 30 seconds I could turn it on again, but it just holds at the google screen again. I'm really starting to freak out as I have some unbacked up data. Even if I can't fix the phone, is there any way I could save the data? I have a locked bootloader and USB debugging is turned off (Yes, I'm an idiot).
It does sound like a faulty power button. Since it's very cheap to fix, I would first find a local lab to change the button. At least rule out that..
If you can't fix the phone, you cannot get the data.
Also, be carful with bootloader and adb, so you don"t accidentaly erase your data.

The nearest phone-repair shop is like 45 minutes to an hour away from me so I want to be sure this is it. How exactly would a faulty power button cause this to happen? The phone isn't acting like the power button is permanently held down or not held down at all and I was able to get through the boot menu to the clear cache partition menu which requires use of the power button (And has the shut-off and blinking red light interrupting the cache clear made things worse), all that seems to be happening is the phone freezes during boot-up.

This sentence points all fingers at the power button
"I've tried shutting it off and on again but it just comes back to the google screen where it sits frozen for about 30ish+ minutes before it shuts off, I can't turn it off otherwise, if I try turning it off it just turns itself back on so I can't shut it off"
If you turn it off and it comes back on. it's the power button
Some symptoms of a faulty power button
If your LG Nexus 5 keeps rebooting for no reason to the Google Logo only
you cannot lock the screen
screen locks on its own
phone turns off for no reason during regular use
Lock/power Button is VERY sensitive to touch

The power button is not dead, it's faulty, and behaves erratically. Sometimes it works, sometimes it does not. It's an educated guess. If you put in a lab, and it's not the power button, perhaps they will know what else could be wrong. It's your call.
Just got back from the repair shop, it's not the power button, it's some unknown software issue. They can't fix it. Anyone have any ideas?
This is very odd. I am not aware of any software issue that can prevent a physical shutdown of a phone. Was this a reputable lab?

The phone shut itself off after a period of time, but holding the power button just restarts it. They replaced the power button just to be sure and it didn't fix it.
When you connect the phone to a PC does it show up? Can you copy your data? If not, I don't think you can save the data.
One more thought: If you put the phone in bootloader state, does it still shut down or restart by itself?
I just talked to the phone repair people and they said they just found out it's not software, a circuit in the motherboard got fried and they only way they could fix the phone would be to swap out the motherboard.
That is a 200$ reapair. Before you do that or give up on your phone try my guide here http://forum.xda-developers.com/google-nexus-5/help/nexus-5-stuck-boot-loop-lollipop-t3098632
I had a different problem but was also told by the local LG lab that it was the motherboard. It wasn't,
If my guide does not help, it probably is a hardware issue. See if the lab has an insurance deal. Over here they suggested to sell me a one year insurance for 150$ , and change the motherboard. That would have saved me 50$....
Hi,
First I hope I'm posting this in the right place - to get assistance/direction that will help my situation. If not my apologies - please send me to the right place.
I have a Nexus 5, Android 5.0.1, Rooted.
- My device was charging then suddenly went into boot cycle - showing the Google logo then powering off and repeating the same. Trying to get into recovery mode was impossible - would power cycle out of there too.
- I have tried doing the multiple fast press, and sticky button clean solution (actually taking the back plate off etc.) posted out on the net but that has not resolved my issue.
- Left my phone to charge overnight. The problem still persists. More accurately. Turning it on without it plugged in to the charger does nothing.
All the following is the behavior when its plugged into the charger:
- Without pressing any button just shows a full battery charge icon for about 8 sec then the screen turns black for two seconds and that keeps on repeating. If I press the power button it shows the Google logo for a 1.5 seconds and shuts of, going back to the battery charge icon flashing cycle.
- Now if I press the power and volume down button It takes me to the fast boot mode screen where can cycle through the menu's <Start, Restart Bootloader, Recovery mode, power off>. None of the options work. No matter which I chose the phone shuts of and goes back to the full battery icon cycle.
- I was thinking a battery issue but, when in recovery mode the phone will not turn off. I can use the volume buttons to go through the menu as pointed above but using the power button just takes me back to the battery icon cycle. Now I'm not sure, battery, power button or software. What could it be?
I am thinking, try a new battery or, damn buy a new phone (my phone has outlived its warranty). If there are any ideas on fixing this I'll appreciate your opinions. If i have to get a new phone is there any hope of salvaging data. I have a 4 month backup on my computer, but my latest is stored on my phone.
Thanks.
If you run into this issue and none of the solutions in my original post apply, read on in case my final solution helps you out (you might not even have to get paid help if you know how to work on the fault I was experiencing). If not - nothing more for you to gain if you read on.
As it stands:
I took my device to a reputable cell repair shop. After describing to them the symptoms of my device the out ruled the stuck power button issue and tentatively diagnosed it as a firmware bug or nand memory corruption issue which would require a nand mem flash which they had the tools to do. I went for it.
When I went to pickup the device. They reported that the device was functional and they did not even have to do the flush. My data is safe. Issue was a loose battery contact which they detected and fixed. It's been 8 hours and all looks good. These guys were going to charge me a $80 bill to do the flash if the recovery was successful, but I had to leave a $56 deposit after tax for them to begin the work and pay the balance if the procedure was successful. When closing the deal they just gave me the device and said since they did not have to do what they anticipated, the deposit I left them was satisfactory.
I have my device back and working (at least for now) and have the chance to make external backups incase the issue reoccurs. I'm happy. Cheers.
