Please notice this !! - Lenovo A850

I have a Lenovo a850 . Okey, the problem with it is that whenever the phone screen turns off it wont turn back on except if I remove the battery . when the screen is turned off I could still call it and the phone still rings so its not shutting down on its own . its just that the screen wont turn on . I cant turn the phone screen on by just pressing the power button, I have to remove the batteries . can anyone help me with this ? its a software problem I think its impossible for a hardware problem because the screen and the button works fine. btw, the phone is rooted, running jelly bean android, and I have tried hard reset it.

Help- on/off power button malfunction.

Orbit2 - the on/off button at the top is non responsive . It means when my backlight turns off I have to reset the device to use it again. I have disabled the backlight timeout for now,but it is an extra drain on the battery and im worried if the device turns off I will not be able to turn it on again. Any solutions ?
Is this an problem anymore?
Got the same now, an opened the device.
The button is mountet at 4 points, at mine 2 are brocken => no contact, no function...
After being quoted 100quid to fix it, I changed the settings so any button will take the device out of sleep mode. It is not fixed but this way works ok .

I have the same problem but can't find the setting that will allow me to un-sleep my phone with any button.
I use rom: 3LIT3_VIII_Full NLD
I think that these setting has been disabled in the rom.
Is there a register setting?
thanks
I do not know anything about roms.
You can turn off sleep mode in the battery saver I think. But means your battery gets used more quickly . The other way I tried was in the settings where any button will turn off sleep mode. This way was better.
Same problem! Although me being the idiot that I am have just dropped the battery and have no way of turning it back on. Any ideas?? Anyone?
Just plug your charger in press the camera and reset then you should get the spl screen then press the reset to boot into windows.This will only work if you are getting power ie from your charger or usb.

Is your phone led lighting up when plugged in ? If not could be usb not working,if it is could be your camera button knackered to so can't get to the spl screen.
Then plug your phone in then do a hard reset except dont press the send button then you should boot into windows without loosing any data.

[Q] Boot button not respoding?

All of the sudden today my htc with cm9 stoped turning on with the boot button, the only way of turning it on was taking out then putting in the battery, does anyone else have the same problem? and i know the boot button is working, because it worked in the morning
i think i broke my button somehow, but it was working just fine... and forsome reason my phone knows that the only way to turn on my phone is when i put in the battery... it just turns on byitself i need help :S
sweep to wake all the way, and volwake thing
and is there a way to use the power menu without using the boot button?
new edit: i think i jammed it because, in the bootloader when it askes me to use the power button, it would go by itself, how do you unjam it..? i can still press on it and feel that im pushing it.. but when im on my phone it doesnt randomly turn off so it cant really be jamed...
i dont understand this

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?

weird bug: once phone is locked it cant be unlocked

Hi, I am facing with a very weird issue. If I locked phone by pressing power button or waiting until time out, the phone can not be unlocked. The phone it self not freezen. If I turn on music, it plays even after screen is locked, I can volune down and up. But the screen is not back on. I have to hold power button to force phone restart. The phone is working fine until screen is off. No application is installed and I have tried to do factory reset. Also, I have tried to enter in safe mode and nothing helps, the result is the same. Maybe somebody had same issue and fixed it. Or could direct me on the right path where should I look. Thanks in advance.
