[Q] Problem with power - LG Optimus Black

Hi all,
Someone can help me please...
My P970 got problem with power as below:
if the screen turns off for long time, the phone also turns off. And It cannot be turned on again. I have to take out the battery, wait a long time then put it back to turn on the phone. Not everytime I can turn it on. I dont know this problem is because of firmware or hardware. If I set the screen on never time out mode, the phone works perfectly without any problem.
Thanks

help me ......... please

[Q] a strange problem with power button, PLS HELP!!!

Hi everyone,,
I hope I can tell my problem properly with my poor language!:crying:
my device got a problem in response of the power button, sometimes it does not work and I did use the volume buttons to wake up the screen instead of it!
then one time the device fall down from my hand and the battery pulled out so the phone turned off. I tried to switch it ON but no way because the button became totally not working
I tried every way to make it ON, I unscrewed the devise and I check that the button was not damaged and every thing looks fine.
I tried to use some ways that are mentioned in youtube like unplugging the battery several times and so on.. but still not working.
I took the phone to a service shop in my town and they made an electrical check for the button and it was working well electrically! but they could not doing more with the phone because they don't have spare parts for HTC devices!
after that I expected that this issue is a software problem, because I installed a custom rom recently!
finally I succeeded to make it ON using ADB commands and I changed the rom 2 times, but the power button still not working, then I changed the Kernel, and the problem remains :crying::crying::crying::crying:
so, do you advice me to try anything else?
Please heeeeeeeeelp
i have the same problem
i have the same problem here and i use cmd to reboot :'( but i have a big problem my mobiles keeps on shutting down alone and i restart it by adb but if i am out of home what can i do ? anyune help us

And if you using custom rom write to the author mayby he will change a vendor key for you.

I was written what you need to make you life easier if you have power button broken. If you have shutdown problem write to developer of rom you're using. Or change it.

[Q] Samsung Galaxy S GT-I9000 won't work if not plugged on external power source

Hi guys,
The following problem has taken me litterally DAYS of reading XDA, trying everything I could, but still no solution. Googling and searching this forum didn't help either, and it's totally weird.
It's a Samsung Galaxy S GT-I9000, on which were installed, almost two years ago, the ClockWorkMod recovery, Darky's ROM, Froyo, and everything was fine for months. Then, one day, out of nowhere, it switched off, without notice. Impossible to switch it on again! I remembered having seen some strange battery behavior few days before, like falling from 80% to 30% with no reason, so I thought of a battery issue. I plugged it for a full night. In the morning, I was able to boot it, but not easily, and all apps were crashing: during boot, or when launched manually. Yes, all I tried were crashing! Then, the phone became fully not bootable: press the power button, the screen shows "Samsung GT-I9000", then switches off...
I ordered a new battery: same result.
A guy from a phone repair store told me to plug the phone, and keep the power button down for 2 minutes: after this, I could reboot the phone, and thus, wipe data (factory reset). But it didn't help.
After "playing" a bit with it, I realized that the problem is:
the phone won't boot if an external source of power is not connected (as said above, white text shows, then the phone "dies")
if started with power cord/usb, the phone will work fine, all the time
if started with power cord/usb, and the external power source removed once the phone is booted, the phone will work fine, UNTIL the screen goes black for power saving mode or by pressing pwoer button, after which, within seconds, you can't open the phone anymore. I mean: if you press the start/power button immediately after the screen goes black, the screen goes on again, and the phone is ok. If you wait for few seconds, it's over, you can't do anything, and have to reboot the phone. This said, the phone doesn't vibrate, so I suppose it's not really off. But then... what is this state??
I really tried my best: updated to GB2.3.6, bricked my phone trying to re-install the CWM and having a bootloop, installed and used Odin and Heimdall, reverted to stock kernel, etc, etc, etc.
I feel sorry to bother you guys, I was really convinced that with the incredibly huge amount of data, how-tos, explanations, etc. I would manage to get rid of this, but this problem, though I don't really think it's hardware (but maybe it is?) stayed across so many kernels, roms, etc. that it's killing me!
For the record:
Model number: GT-I9000
Micro-software (?): 2.3.6
Baseband: I9000XXJW4
Kernel: 2.6.35.7-I9000XWJW7-CL1125830 [email protected] #2 (problem was the same with [email protected] #2)
Version number: GINGERBREAD.XXJW4
Any help would be greatly appreciated, considering that a wireless phone that needs to be wired is a little bit of an issue... :laugh:
Thanks in advance !

That's a very strange problem... let's try something, remove the battery, sim card and sd card and hold the power button for 1-2 minutes, btw when the screen is off, is really the phone off or just the screen? did you try to make a call to your phone when the screen is off?

Hi timberman thanks for the answer!
You're very right: I totally forgot to say that what initially allowed me to restart my phone "regularly" was this procedure of pressing the power button for 2 minutes (hint given by a man from a repair shop). Before this, I couldn't (kind of a bootloop).
It's a very good question! I don't think the phone is really off in fact, because there isn't this vibration saying the phone turned off... Let me try to call it!
F..k! I was redirected right away to the voicemail... so... phone was off
I'm starting to think it's an harware issue... I reinstalled lots of ROMs, kernel, etc. Same ****...
Any idea?

Hi! Answering is already nice
I tried the button pressed for 2 minutes without battery: didn't change anything.
I tried playing a sound: MAN, YOU'RE A GENIUS!!! Launching the music, then forcing the screen off with power button lets the music play, and OF COURSE, I can reactivate the screen by pressing the home button. The screen goes off normally again after few seconds, but the music is still playing, etc. So, as long as the music goes, the bug doesn't happen!
Other hints:
For some time already, when I was removing the phone from my ear after a call, quite often, the screen was staying off, and I had to press a lot of buttons to have it on again, and be able to close the call
The moment where it crashes when booting without power is the very INSTANT where the initial white text (Samsung Galaxy S) goes brighter. So, if you unplug the power cord just after this, the boot ends normally. In summary, something happens at boot just after screen brightness changes which is the same thing happening when the screen goes off for power saving. All this, only when no external power is plugged.
Hehe, we (you) are making progress

Hi again, it seems like your phone is unable to exit the deep sleep mode or something like that so, let`s try another thing, in ICS or JB there´s an option in the developer option settings that unfortunately is not present in gingerbread roms, so, you can try to switch to a ICS/JB rom and go to settings-developer options and disable the "PM sleep mode" let`s see what happens then

I tried to install ICS, with a GREAT tutorial found here: http://forum.xda-developers.com/showthread.php?t=1494493 Sadly, the phone reboots after installing the ICS kernel, and then doesn't work anymore, I had to reinstall the Gingerbread (I tried twice).
Last news: I let the phone play music (sound muted!!) for about 12 or 18h: all was fine! So I decided to pause the music, and see what happens. Boom ((c) Steve Jobs)!! The screen went black, and phone was "dead". I was expecting this, so no panick, I put back my SIM card, my SD card, and tried to reboot, with power cord plugged: it boots until the screen shows the small loader animation, then the empty battery image, but then goes black again, instead of showing the charging battery!! Download mode is still available, so I'll try to reflash the kernel, say.
It's like if each time screen was put black, phone was dying.
I can't stress enough how I appreciate your help: even if we can't save my phone, it's very pleasant to be able to TRY things. Thanks man!! :good:
Update: I reinstalled all... and it's not, even with power cord in, going further than the "Samsung Galaxy S" white text. The moment this picture disappears from screen, phone is dead. For good this time ?

Hi! No, I didn't, I used Odin. But now, I can't try anything anymore The only "results" I can get from this phone are:
- enter download mode and update from Odin (maybe from Heimdall, too, but I didn't check)
- reboot until the first moment the screen goes black, after which, the phone becomes fully unresponsive

[Q] Random shutdowns

Hi guys,
I've been having quite a problem with my HTC One. Sometimes it just turns off. But it doesnt just turn off, its completely useless after that. I can not start it again after the screen turns black. I always have to connect it to a charger and press the power button and disconnect it again and try turning it on for ages until it starts up again. Besides from that everything works perfectly.. I was really hoping u could help me... Thanks in advance
Basic info is needed-
Device model
Rom
Kernal
Mods(underclock, overclock, voltage changes)
Anything done shortly prior to the symptoms...........
Well I have a german o2 branded Htc One 32 (no dev Edition). It is still on stock, not rooted and bootloader unlocked. I actually did NOTHING special to the phone I installed normal apps( a few games and navigation software and such) and synched music on it so nothing that could provoke such an error

[Q] Phone shuts itself down

My phone was shutting itself down so I decided to root my phone and flash a custom rom. First everything was alright but afterwards it started again to shut down randomly. It shows a notification: "Shutting down" and when it is off I can't turn it on for a while and it's led notification won't turn orange when I charge it. What could be the reason? If anyone could help me I really would appreciate it. Thanks in advance. I'm very new to this forum so sorry if I did something wrong

Today I discovered that when I put my phone outside my room (around 4 degrees celsius) my phone will start immediately when cooled down but is shutting down after it heats up to the room temperature. Is there a way where I can disable the function where the phone won't turn itself down. I tried your method elia but still it starts shutting itself down.

[Q] Help! Trying to troubleshoot and hopefully solve problems with HTC One.

Hey guys, could anyone shed some light on what's wrong with my phone?
The initial problem was that it would display a notice that the phone was going to restart, the phone would turn off but not reboot.
When trying to turn the phone on immediately afterwards, it wouldn't turn on. The first thing I tried was seeing if that battery was dead but even when I plugged it in, it still wouldn't turn on nor was the charging light on.
After leaving it for a while, I tried a hard reset but the phone would turn off after 2 seconds in the boot menu. After a few hours and a lot of expended patience, I got the hard reset done and it worked flawlessly for around 30 minutes then turned off again.
Right now, when I turn it on, it shows the HTC screen, the backlight for the icons at the bottom flashes around 10 times and it turns off.
Any idea what's wrong?

Kinda sounds like your power button may be sticking in. Is the device bootloader unlocked and rooted? Or still stock?

The phone has been unlocked to be used with SIMs other than from AT&T but it hasn't been bootloader unlocked or rooted.

Ok I would recommend you check warranty to see if it is still covered. To try a software solution will mean unlocking the bootloader which will void warranty. And may not fix the problem. As I say it seems like the power button is stuck in.
When the capacitive buttons flash like that it is because of a forced reboot by holding in the power button.
