[Q] Power Button problem - LG Optimus 3D

I need help to solve my power button problem. Whenever my screen is off (screen timeout), I cant turn it on back unless if people call, sms me or charging it. However if I remove battery and insert it back,I can still boot it up with the help of charger. Without it, it will just show LG logo before shutting down again once I press the power button.

phone shutting down - power button stuck?

I have a Fuze that wants to shutdown all the time. I usually run EnergyRom on it and the slide to shutdown screen keeps popping up. When I run a stock rom on it, it also shuts down, as if someones holding the power button.
has anyone ran into this issue or have any idea how to fix it? I've searched for a while and can't find anything.
thanks!
Opening up the phone enough to get to the point that you can remove the power button itself and clean that area of the phone should fix the problem.
This even helped me on my previous phone where I thought the button was losing sensitivity. After reassembly the button worked beautifully again.
I had the same problem...and then all of a sudden my power button stopped working altogether...its weird because it works fine to turn the phone on, but once it boots it doesnt turn off the screen or bring up the shut down menu or anything
how did you manage to remove it to clean it out?

galaxy s3 power button dead?

hi
is it possible for the galaxy s3 powre button to stop working? i used a aftermarket battery not sure if it play any part in the dead power button. but want to tell you that too. the power button seem dead to me or something is wrong with it, i take out the battery and put it back and the phone vibrate and a quick flash of the word "samsung" and stay fully dead. it turn on by itself when i insert the battery without pressing the power button. i can do that many times and sometime the phone work and it get to the home screen and all buttons work except for the power button. no matter how hard i press it it wont turn off the screen or anything. anytime i got lucky and it boot to home screen, i plugged in the charger so that way everytime the screen shut off i can turn it back on by unplugging the charger, and that turn it back on... otherwise i cannot turn it back on with the power button...
anyone solved a problem like this power button issue? what could be wrong? i know the phone is not dead ,, so could the powwer button issue trigger multiple issues for the phone?

if you can get it to turn on u can use a app to wake it up by sensor.
Could be related to the 3rd party battery but hard to tell without checking out the internals to see if anything on the PBA got fried.
If you're able to get it to turn on with an app and not able to unlock the screen without use of the charger it may just be somethin to do with your power button itself.
Did anything happen around the time of the issue starting? (New apps, physical or liquid damage, software updates, etc)
Have you tried a known working OEM battery?

Phone won't boot up

I have researched the "related threads" and none are similar to the issue I am having.
The phone turned off midcall and fails to turn on afterwards. I thought it was the battery, but it still fails to turn on after charging over night.
It boots up to show the logo, after a battery pull and turns back off.
If I I press down the power button + down volume+ menu, I get the warning about a custom install of an OS may damage the phone and if i want to continue to press the volume up, or cancel.
The phone only lasts about 5 seconds, after every battery pull, other wise it won't turn on again.
I haven't gotten a blank white screen nor the Android logo.
Thank you.
Update: I believe I confirmed it is a power button issue.
What I used to confirm it was pressing the volume down button and menu without the power button and was able to see the Warning as if I had pressed all three. Also, the phone vibrates as soon as I place in the battery.
Issue now is: Supposedly the cause is due to a stuck power button, but physically the power button is not stuck. It clicks when pressed.

Phone will not turn off, screen not working

The LED light is blinking (slow), i touch the screen, push the power button and volume buttons and the phone will turn on. I have to plug the charger or usb so the screen can come on. I swipe the screen, push the power/volume buttons and phone will revert back to black screen. Can someone please tell me what is wrong with the phone!

To force the phone to turn off hold down the power button (and ONLY the power button) for a count of 10 seconds....the phone WILL power off as it's a hardware function...however if you have the phone plugged into power it may reboot right after back into your rom. While disconnected from power it will stay off. You may need to do a factory reset to get rid of whatever is causing your rom to act that way.

Black Screen and Not Powering On

Hi guys,
TLDR; Phone won't turn on, notification light flashes red once on power up (sometimes), black screen all the time. :crying:
So my brother has asked me to try and fix his Nexus 5 as he isn't tech savvy at all.
So the problem he is having started when he tried powering the phone on and it started to boot up and then started resetting iteself.
It now will not power on at all and doesn't seem to be on at all.
When holding the power button, it will sometimes flash the notification light (at the bottom) red for a second or two. No other response from the phone.
I've tried holding the power button for up to 5 minutes with nothing. I've tried holding the V+ key with the power button for a few seconds up to a few minutes then tried pressing the buttons expected to get to a reset menu with no indication of anything.
I'm kind of lost and was wondering if anyone has had these issues before and know what is the best issue to try and repair?
Thanks
It could be a faulty power button which is a common issue with the Nexus 5.
Remove the logic board, clean around the power button with isopropyl alcohol, dry it, quickly press and release the power button using more pressure than normal, re-install, and try to boot.
You could also try this: hold volume + button and connect the phone to a computer using a USB cable.
Thanks audit13, I'll give it a shot and shout back if it works
