I am owner of a Lenovo S6000L-F tablet and suddenly the power button stops to responce when the tablet is turn off.
To turn it on, I have to use the combination of power button + volume down, to go into factory mode and then choose "reboot" .
When the tablet turns on, everything is fine. I can use the power button to turn the screen on or off and I can use it to turn the device off. I believe that there is no hardware broblem because the power button works fine when the tablet is on and it has power. The problem occurs only when the tablet is power off.
After all I tried to reset the device to factory settings with no result.
The only way to turn on my tablet (exept with factory mode) is to connect it to my pc via USB cable and then the power button works as usually. This tip is working ONLY when I connect the tablet with USB cable to my PC and NO with the USB power charger.
Please I need your help.

I've got a Chinese tablet that boots properly up to the unlock screen, where if I'm quick I can unlock, I can see wifi is connected, etc. but around that point it completely freeze, even the power button doesn't turn off the creen and I have to reset it by long pressing the power button.
I tried all combinations of keys to bring up a recovery (power + volumes) without luck so far. If I press any volume or back key while powering up, the tablet doesn't power up and stays black. adb isn't finding the tablet. I opened the tablet, there are pins to connect a rx/tx serial. I could do connect a serial adapter to it if that could be of any help.
Actually, at this point I don't care much about the tablet but that could be a good opportunity to start learning a bit more about Android hardware development, just don't know exactly where to start.
Any tip?
Phone was running LP Pacman rom and did fine for several weeksbut then started bootlooping for no apparent reason. Now it bootloops if I plug in the charger cable or hold down both volume keys or the volume down key even if I dont press the power button. If I press the power button by itself without plugging in the charger cable it doesn't do anything. When I take out and put in the battery the "SAMSUNG" logo come on momentarily but then nothing. I cant get it into recovery or download mode and Odin doesn't see the phone. I didn't drop the phone or get it wet or anything. Any ideas? does this sound like a hardware problem with the power button?
Hello,
I just flashed this rom: http://forum.xda-developers.com/z3/development/rom-zyxxos-5-1-1-v1-0-pure-stable-fast-t3229169
on my z2 (D6503). Yes, I know how dumb I am.
So the thing is, the phone won't boot.
Nothing happens.
No LED's, holding power button + vol up also doesn't work.
Red power button also doesn't work.
When I connect the phone to the PC nothing happens. It won't get detected.
Any idea how could I fix this, or is it hard bricked forever?
Update1: When I connected the phone to the pc and disconnected the battery from the mainboard the red light started blinking.
have you tried flashing a normal z2 rom?

Nothing works. No flashmode, no fastboot. It doesn't turn on. It's completely dead.
start the flashing process with flashtool and your phone disconnected
Hold Power button and the volume UP button until you feel your phone vibrate 3 times. Now its off.
when the program asks hold volume down and connect it to the pc/mac.
Hope this helps otherwise i dont know.

Guys, please read the post.
Nothing works.
Vol Up + Power button does nothing.
Anyway, I have access to battery so it's off for sure.
i have read the post and i am wasting time trying to help you. Though maybe you didnt hold them long enough..
anyway
try
pressing and holding all 3 buttons (power,vol+and vol-) all at the same time till it vibrates once then let go of the power button and vol+ but keep holding vol - while plugging in the usb cable this MiGHT boot your phone into flash mode
Have you make the phone works?? I am in the same situation! No buttons work, no power, no volume, no red reset, neither testpoint, when i plug it to the magnetic port screen shows sony logo, left for some minutes just let the phone overheat and no more! Plug battery out and turn off, but no more! Completely dead!
Good Evening
I own a Samsung Tab S2 (SM-T810) and I am running stock firmware (Android 7.0), rooted and TWRP as a custom recovery.
Yesterday i was using my tablet when the screen suddenly turn off, i tried to turn on the screen as i usually do, with my power button but it doesn't work, i connect the charger and the screen wont turn on (like usually do).
So i go to TWRP and i realize that every button was working in there, if the screen turn off i can wake up with power or home button like i normally do on the stock OS
The problem begins when the system (Android 7) initialize, the navigation bar + home button wont work from the beginning , the power button works only for turning off the screen but not to turn it on, the volume buttons work until the screen turns off
Once the screen is off there is no way to turn it on, neither power button, connecting it to the power, or notification, the only way is restarting the device by long pressing the power + volume down
I already do:
wipe Data, Cache and Dalvik from TWRP
Reflash my stock firmware with Odin
This is my first time posting a question on this site, if you need more information please let me know.
Thanks in advance
I just remove the Samsung cover from my tablet and it fixed the problem!
Samsung Galaxy S9+ No custom, Just a normal phone from T carrier.
The situation is as follow. I wake up everyday and cannot turn on my phone, the screen is black but I hear it beeping when i press the volume keys. I do a Vol down Power to restart thinking it will , it restarts but the screen is black and unresponsive no matter what I do, the Power button is still functional at this moment.
What I quickly did is I connected the phone to my monitor using USB-C and i have a mouse connected to the internal KVM of the monitor- , perfect got excited that the phone at least works, on the monitor it shows up perfectly, I can control the phone with the mouse, enter my 4 digit password, works. That was the situation yesterday. Should have backed up then but didnt.
Today I wake up, the Power button does not work, so I read and find out that I can go downlead mode which I did using the Vol down and Bixby and plugging the charger.
tried the Vol Down and Power to restart it does not, so again I go in to the download mode and accidently press Volume up, Now I am completely stuck on Downloading... Do not turn off target
1. Power button does not work- I have no idea how to get the past Downloading screen now
2. Would I be able to recover anything it its really dead?
3. Any tips?
