Power/lock button doesn't work - LG Optimus Black

I woke up this morning, and when I press the (Power/lock) button, it didn't wake up the phone, after several intents I managed to unlock it by pressing it many times. What could be the problem?

It might be just the Rom! I noticed that OB roms has this lag before the screen wakes up. Or maybe it's a hardware malfunction. in any way you can remap your G-button as Power/lock!! And I recommend you doing it ASAP if you don't use the G/button, as if ever your power button REALLY stops to work, how will you lock/unlock it!?

I had this issue too.
While pressing hard in the screen, where the LG logo is at, made the button work.
I opened the phone, the flex connector was weak and didnt make good contact, but seemed ok... LG quality sucks.
I fixed it by tapping a bit of tape over the connector, so when closing the phone it makes some force over it.
I recommend thinking twice before buying LG again. My phone also dropped from a chair (half meter) and the camera broke up.
I also fixed it with a replacement...but...Life's Good

Power button not working right on HTC Diamond

Hi, I cleaned the screen of my HTC Diamond with a bit of alcohol and a pice of tissue and it seems that the alcohol got inside of the Power button. Now, every time I try to turn the screen on by touching the power button, it turns the screen on but it dispays a message that says: "Warning: Power will be turned off and you may lose data if you have not saved them. Do you want to continue?"
If I click YES, it reboots the phone, If I click NO, then its ok. That is fine, but the problem is when I want to turn the phone off. It's impossible. It will keep trying to reboot.
Does anybody know what can I do? I am really worried.
One solution could be to make some other button from the phone to act as the power button (like the Home button that is rarely used). How can I do that?
Please help!!!!
Thank you
Hi,
I have the same problem.
Did you already find an answer ?
No, I didnt find the solution. I tried to fix the hardware but didnt succeed. So, I created a dummy file to emulate the poweroffwarning.exe that pops up when you long press the power button.
Solution
Hello, I have one AT&T TITL 8925 that upgraded to Windows Mobile 6.5
After the new software was loaded I saw same behavior on my phone.
When the phone is ON and I pressed the power button sometimes it do not respond, and others I received the warning message "power will be turned off and you may lose data if you have not saved them..." My first tought was that it is because the processor is slow to this new software release, or maybe my phone is damaged. I was working perfectly with previous (light version) release so my final guess is that this sw requires more uses of the processos.
Anyways what I have been doing is before turing it off I press the red button or hang up button, and after this if I press the power button it works fine (No more warnings). I have some theories but I will keep doing the same
Hope this partial solution helps you as it does for me.
Regards
Jerry
this is not working for me :| the problem is i can't use my power button not even to open my display when it goes to sleep :|:| i don't know what to do guys please help me
You can use the Stylus to awake the phone, instead of using the power button. You can also use TouchLockPro, to suspend the device, so you do not need the power button for that too.
Also you can set the phone to awake on pressing any key (Windows Mobile Setting), but be sure to have a good locking tool, which makes sure you do not have bogus calls and it goes to sleep again fast enough, otherwise it will drain battery.
I have the same problem.
Anyone solved this one?
I have the same issue and this is not a hardware problem. Strange since even updates/changes of the rom do not correct the issue. Did anybody find a solution for this...?
Well.. ive had this problem just ones.. I was walking downtown with my diamond in the frontpocket of my jeans (face down), after about 3min. of walk, it started to rain (big drops), and my clothes got completely wet, i turned around emidietly, to walk back to home. When i got home after 3 more min. i layed the phone on the table, and then i could hear there were somethibg wrong.. The "turn off" sound came, and the notification kept on coming up, even though i pressed No, as if i were just holding the power button down.. Then i began to press the power button continuesly for about a 100 times, and to my surprise then it stopped and have functioned perfectly for about 2 month now.. Something tells me theres some serius promlem with the smallest kind of moisture near the power button on this phone..
Yes this is hardware related.
If you take a look at the inside of the powerbutton, there are 2 points making contact when you press the button.
If you press it, the software will recognize this and the screen will turn off.
If you press it long enough you'll get the "Do you want to turn off your device" message.
But, if water gets underneath the button, the 2 points may be making contact, because water/alcohol conducts.
In this way you'll get that message.
The button is very weak. Due to this, it may not properly work if you have used it for a long time.
I think that could also be a reason why you constantly get that message.

Hi! on one of my diamond, the power button off from the board. So the black little board with the button itself is not part of the complete circuit anymore... if someone know the hw testpoint for that it would great please.... i see a few TP around, but if i just start sorting them i just going to kill it...I use to flash phones with TP so is not new for me , but i find nothing for diamond.
I have a similar issue. Mine seems like it is almost stuck on, so it wakes its self up all the time, meaning a full charge lasts an hour or two. Then when it runs out of battery it tries to switch itself back on, so goes through a continuous cycle of vibrating and beeping until the battery is removed. The gf finds it very annoying at 3am lol.
Don't recall mine getting wet, but it's possible it could have got damp at some point, but it's been doing this now for about 3 weeks.
Tried a hard reset with no luck.

I think I should send it to HTC, and ask them to do it. Or go to a repair centre. But I should not try it myself, because it can be dangerous for the diamond.
Also try searching on ebay, there might be the parts you could use.
Good luck!
is there a way to remap the power button?
my diamond face same problem since this afternoon, arrrrgghhhh!!!
- blocking hwbutton1, hwbutton2, hwbutton3, hwbutton4, hwbutton5, hwbutton6, hwbutton7 >>>> NO LUCK
- hard reset >>> NO LUCK
guys, any of you solved the problem yet

My Sony X1 have some strange problems with the power button. When it goes into sleep mode, I can not wake it up with the power button, all I can do is to soft reset. Sometimes it does not go into sleep mode either , it just "wake up" all the time. I don't know what's wrong with it, tried Hard reset but no use .
ANyone had this problems before?
@
The only way to solve this is to leave the phone near your laptop heat vent ( fan) . hot air from it might help you to get the power button up and running. But if that to doesn't work then i'm afraid thats bad.
Current sol :
1. download SU2U ( search threads )
2. go to the settings and make the " lock when stylus inserted" option ON
3. Change the screen turn off time to 5 secs..
So , to unlock , remove stylus , to lock -> insert it back ( its turns off the back light within 5 sec )
Less annoying

Htc Tytn 2 Screen problem

Hi everyone,
I got a HTC Tytn 2 and i have a problem with it.
When i boot the phone it starts up and goes into windows like every windows mobile phone.
But when i press the standby button my screen wont go out of standby.
Only when i reset the phone it will work again.
Anyone got idea's ?
Oke, since no one responded.
Is there any way how i can make the Power Button replaced with the Speed Dial Button.
Because i think my power button is broke.

Have you at least tried backing up your data and doing a hard reset first ?
Yes, and i have also tried to put on a new rom and even updated the radio.
Iam a little bit out of idea's...
here are some more ideas:
1. how to test the power button: you say pressing the power button does not wake up the device once it goes to sleep. conversely, does pressing the power button put the device to sleep while the screen is on? if the power button is unable to make the device go off->on as well as on->off, then the power button is likely broken. if pressing the button achieves on->off, then the power button is probably ok and some software issue becomes more likely.
2. how to enable wake on pressing ANY hardware button: look for an option in Settings. i can't tell you the exact option because the ROM i am using does not have a link for this option, but this option does exist 100% in stock ROM and in lots of other ROMs. it contains settings like "Lock all buttons except power button" and "Keep all buttons unlocked" or something similar. by using the second option, pressing ANY hardware button while the screen is off will wake up the device.
3. you can use AE button plus to perform even more advanced button (re)mappings.
4. just to be sure that your device is really working correct, does the screen wake up when you call the phone or when you receive a text message? if it does not wake up even then, then search for "sleep of death".
Thanks for the response.
I think its a Service of Death problem.
Because when i try calling/smsing it, it wont go on
The buttons do work then...hopefully there's a fix for this problem...
Oke, i tried switching to 2G or 3G only but that didn't fix my Standby of Death.
I also bought a new sim card of vodafone so i wont get a No Sim error.
But what can i do now about it...it hangs like every 5 min...
Okay, after a will testing, the phone hangs every time its almost like when iam on the road with my tytn 2 and placing it upside down, it hangs.
But when iam putting it in the leather holder it doesn't hang.
Any had the same problems ?

Power button not working

Anybody having problems with the power button not working?
It doesn't work at all no matter how hard I push. At times it works without issue, other times I have to use the camera button to wake my phone.
Anyone else with this?
Defective unit.

Did you both ever opened the phone, maybe for repair or the.prevoius owner? Maybe check the "outside" when opening phone (and removing LCD) many times the button flex cable gets damaged or get a small crack so it stop working after some time... The button flex is mounted very easily, maybe just need to get it back right into position and make sure it holds the contacts. The whole flex is just 6euro, repairing easy.. Just follow "ifixit"

I had a problem with the power button on my phone recently. It was off, just like you describe, guys.
But the combination: power button + vol UP, to force a reboot of the phone worked and after booting, the button was working and the problem never occurred again.

[SOLVED]HTC One M7 thinks I use buttons, doesn't respond.

Hi all!
First of all, I'm not sure if I'm doing everything right here, so excuse me if I'm doing something wrong
I'm new.
I've had my HTC One M7 from aliexpress.com for 2 weeks and 2 days now.
Have had great fun of it, nothing seemed wrong, was working perfectly. There were some rumours about an unofficial android-version that was put on this phone, which might be the problem..
Everytime I turn the phone screen on it thinks I hold/doubletap/tap/repeatedly tap the home button, and sometimes when I power it off it thinks I hold the volume down-button and takes a screenshot.. When I finally get to type my 4-digit pin code, it unlocks, goes to home screen, does the same again. Seems like my phone thinks I'm using the buttons..
I've changed settings (in a legit official way via Settings) of my home button to Hold for menu, Hold and swipe up for Google Search, and double-tap for recent apps..
Have tried factory reset twice, have tried rebooting it over and over, have tried almost anything.. I'm at the point of buying a new phone now, because I fear that HTC will not help me because it's an unofficial version of Android.. Any suggestions?
Everytime I open an app it just closes it and goes to home, sometimes before it does that it opens recent apps.. After that it just freezes and I can't touch it. Sometimes after waiting a couple of seconds, I can tap the screen and maybe it's fast enough to open for example WhatsApp, and then it just shuts off and does what I just stated.
Really weird!
I'm quite desperate. Could a custom ROM (Cyanogen or Android lollipop) fix this perhaps?
Please, help

This is purely a hardware issue. Your home button is somehow always in "on" position. Given it's a capacitive button, it could be the digitizer or a scratch on the home button area

Should I just send it back to HTC or can I fix this myself, with your heroic help?

Seems like just the thing I wrote. Considering it's a hardware issue you could replace the screen-digitizer assembly by yourself if you are familiar with that kind of work. I tried once on my old Desire and fried the motherboard, so I don't have cojones to do it [emoji6]

Note 5 Touch Screen Is Unresponsive To Fingers

My Note 5 Touch Screen Is Unresponsive To Fingers it only respond to S Pen. I tried several restarts but nothing.
Please help!
I have the same problem .. unfortunately I was unable to fix it... so I changed my Note 5 for a Xiaomi mi5. It happened twice and the second time there was no coming back, the first time I was on MM and the second in Nougat custom. What you can do is to hold the power button and volume down button at the same time for 10 - 20 seconds then selecting power down It worked for me the first time, hope it works for you. This can also happen for water damage. Good luck!

Same thing happened to me after my Note 5 got wet by rain. It works only with the S pen. I tried to power down holding volume down and power button for 15-20 seconds and nothing. Another thread said factory reset and I tried that and still nothing. I'm sad because I love this phone and was working great until this.

Are you on MM or Nougat? there was a code you can dial in the phone to restart the digitalizer and it could work.. I don't remember the code though.. Lets find a solution this is bull****!
any solution yet?

Everytimw you shutdown the the phone or the screen is timed out the digitizer turns off instantly so whenever next you turn on the phone the digitizer gets turned on as well as recallibrate itself if the digitizer was always on then we could have native double tap to wake!
