Power button problem

Hi all,
My XDA IIs works well before. But few days ago the Power button doesnt work properly, it can turn on the phone, hold to turn off the back light, but I can't use it to turn my phone screen off like before. Anyone has same problem ?

Can you see any part of the screen? It might just be that the backlight adjustments are set too low when the unit isn't cradled. You might be able to see the screen in daylight.. or maybe it was inside your home. I forgot where I was at when it happened to me. In anycase, if you can see a bit of images on your screen, go into the Backlight properties and change the setting to your liking.
Good luck..

The problem is i can just press the power button to turn off my phone BEFORE (the screen is completly off), and NOW it doesnt work at all ! When my phone was off, I can press the Power button to turn it on, or when I hold it for few seconds the back light will be turned off, but press once to turn off. I dont know why, if somthing wrong with the Power button it should be doesnt work at all, that's mean i cannot turn on my phone as well. But other functions of the Power button are still work well, except the 'Turn off' :roll:

power off doesn't work anymore
I have the same problem here. I can't use the power button to power off my qtek 9090!!
i can use the power button to turn my pda on and to switch the background light on and off - so the "hardware side" of the power button is working.
however, i can't use the power button to turn off the device. it's very annoying, because i can't put it in my pocket after finishing a call :-(
this should be some sort of a software problem - so i hard resetted my device (a couple of times) - but that didn't help!
can anyone help?
thanks,
lorenz

the ba doesn't turn off it is always on staand by mode. ->settings -> system -> button lock
this will stop any missed call because when the ba is in standby the power button is the only one to work

power on is no problem. i can't put my BA into standby mode. if i press the power button while the BA is turned on, nothing will happen. the screen will stay on, the background light stays on.
i have no way to put it into stand-by with the power button!

try this and see if it works. it's a software app that wil rest, shut down, and turn the screen off. just copy it to your BA temp directory and install it.

power button problem
Does anyone solve the problem???

Had the same problem...
I had the same problem going on for about two weeks or so...never changed anything and it went away all by itself.
The problem has not come back now in over 4 months.
Sure would love to know what the problem was tho...

Power Off does not work
Add my name to people with this problem.
The only event I can link it to is this: I deleted my Motorola Bluetooth headset and installed a Logitech headset. I noticed the problem (can't turn OFF with POWER BUTTON) soon after that.

same problem for me ..... someone must know !!!!

I think it is a hardware problem. The contact is not making cleanly. Disassemble and spray time, perhaps.

It's a standard push switch, easy enough to replace, I occasionally list themon ebay but any phone repairier should have them in stock.

i had same problem yesterday afternoon, but it is ok now. recovered by himself

Write again in two weeks and let us know if it is still healthy. In my case, anintermittent problem became continuous.

Can't turn the screen on after pressing power button
I have a problem with my Bell Atrix. After pressing power button to lock the screen, i can't wake up the screen up by pressing that button again. Could anyone tell me how to fix it pls.

Can't power off... volume goes down by itself...

Guys, need help... can't figure out if it is a soft or a hard problem...
Have had SX66 for 3 years. Almost never a problem (except for occasional thing when people could not hear me, I could hear them, but after soft reset that thing usually corrected itself).
However, just recently got a real problem.
- Can't power it off. Power buttom only works on powering on, but not on powering off.
- At the same time, the volume window pops up (with two volume sliders, "on", "vibrate", and "off), and the left slider automatically slides down on its own, preventing me from accessing anything else. When I try to do something else, go to Programs, or else, this freaking Volume window keeps popping up, and left slider keeps going down and stays down there.
When I try to increase volume, it keeps going down right after I raise it. And the volume window is almost constantly popped up.
From time to time, it disappears, allowing me to do something for several seconds or even minutes, but then pops up again.
Yesterday, I even managed to do something for several minutes without it, and even managed to turn SX66 off, although I had to press the button for a second longer than usual to turn it off. Today, no luck, can't power it off. If I press it for a bit longer, it just goes in "dimmed" screen mode, but stays powered on.
Any advice?
Thanks.

I guess, I'll have to try to clean the power button and volume slider on the side. Looking for good disassembly instructions. Found one, but more would be appreciated...

I have the same problem. I was starting to think that there is no way to turn of BA . Any help?

I have the same problem, only that mine is a HTC touch dual (niki).
the volume screen keeps popping up, and does a "volume down" command... sometimes it goes away, sometimes it comes back...

:S
Ive got a similar problem ive upgraded my BA to wm 6.1 (Xplod) the problem that i am having is that i cant seem to power it off..only way that im able to do that is by removing the battery..when i keep the power button pressed only the backlight turns off but no the phone..How to i power it off?
and secondly ive a problem with the keyboard..while writing some times i press a key and it keeps typing that for example i write s it keeps writing ssssss or giving spaces untill i press something else...is this a software issue or a hardware issue..cant seem to figure it out

I know this thread has been a while but if anyone has the same problem, you'd probably be interested about what i did.
well i had the same problem of the volume going down by itself and the volume icon pops which basically lets you do nothing.
tried all the approaches thinking it was a software issue. but i finally went nuts and took my torx screwdriver, opened the blue angel and tore off the part in the motherboard where the outer volume lever is attached to.
It worked.
So if you could with the fact you wont a direct volume adjustment at the side, you could probably try it

Reboot on screen UNLOCK with power button

Guys,
I got a strange problem that pisses me extremly off.
My Desire reboots when I try to normal unlock the screen with power button :-/
Im running Cyanogen7 stable. Never had any issues.
The phone went into water a few weeks ago but never had any strange behavior. It was all right. Few days ago I noticed thy my screens suddenly light on and off on and off...as pressing the trackball over and over again to wake up the phone.
Also the volume went down automatically as by magic hand. So the phone kept it on vibration suddenly switching the volume down.
I don't know what is causing it, but it is definitely annoying and frustrating.
Any ideas on what can cause such behaviour? I tested all buttons etc. seems to be alright.
UPDATE 1:
I just found out about the VOLUME DOWN + TRACKBALL + POWER BUTTON shortcut to soft reset
the phone (reboot instantly) I think thats the cause of my problem. Anybody know's how to disable this?
UPDATE 2:
Solved. It must have been my trackball that was faulty (howeever it worked) and keep the phone
rebooting. I took it out of the phone (got a ugly gaping hole in the middle though)
Since that It works perfect. No strange volume up/n/downs and no reboot on screen unlock.
All of this was caused by soft reset being triggered when I tried to unlock the screen and clicking the
power button soft reseted the phone every time.

[Q] Volume goes up automatically, power button doesnt work

Hi,
I have a Blue Angel (XDA IIS) that has been flashed with WM6.1. I have been using it for a few years until recently that I got this weird problem.
While the phone is idle, suddenly the volume increases automatically by itself, as if some one pushes the volume slider up, and keeps pushing it. As a result, the speaker keeps beeping as the volume already hitting the max.
After awhile, it will then stop. For a short while later, it starts again. While this is happening, I cant turn off the phone using the power button on the top. But I can turn off the backlight by doing a long-press.
I have tried to reflash the firmware and also did a hard reset, but it doesnt solve the problem.
Anyone has encountered this weird problem? The buttons seem to work fine when not in that weird condition. If it is not software problem (since I reflashed it) and hardware (buttons work fine in normal situation), what else could it be?
Any idea anyone? Really appreciate some advice.
Rgds,
CH

[Q] Screen not starting up for power button

Hi,
I started to get a weird problem since last week. I've had this phone for about 3 months now and never had any problem like this.
It all started one morning when I wanted to stop phone alarm. The alarm was going off but the screen was black. I pressed the power button to wake up, but it was still black. After couple of times pressing the power button the screen came up. First it was not that often but the situation started to get worse. It came to that I can sometimes cannot turn it on for a long period of time. I need to keep pressing power button, volume buttons and eventually it will come up.
This is what I've found so far:
1) When the power button is pressed, although the screen doesn't start up, I can see the three buttons at the bottom lighting up. So it is not a problem of the power button.
2) When the power button is pressed, although the screen doesn't power up, the screen seems responsive. I can feel the vibrations when I tap (I have a startup password)
3) When the phone is connected to a power supply, screen always starts up without a problem.
4) Screen will start up more frequently when the batter power is high.
It seems as though there is a connection between batters power and the screen not starting up. But then again, once the screen comes up (after not starting up), then it works fine, until I turn the screen off.
Has anybody experienced anything like this before?
I did a factory reset thinking it might be some application I installed but it didnt help.
I had to send this phone once to repair the speaker and cost more than $80 just for courier. I don't want to spend another to get this fixed.
Thanks.

I have this problem or a problem very close to this. I have a HTC One X (international version). I'm running the latest version and updates and the problem has existed for at least the last two updates.
Android Version 4.1.1
HTC Sense version 4+
Software number 3.18.401.1
I have the screen lock pattern turned on.
Sometimes when I hit the power button, the phone does not turn on and so I press it again and only after a third press does the phone turn on. I then unlock the phone and use as normal. So, several times per day I have to press the power button three times before the phone turns on. But other times I press the power button once and it turns on straight away. I've just turned the pattern unlock off to see if this makes any difference. I'll start to record the exact details of when I experience this and see if we can work out a common cause.
Hopefully if enough people report this problem then they can send out an update to fix this problem.

I'm pretty sure this is a hardware issue. I bought mine from Expansys and sent it back to them for repair. It's been more than a month and they say they're still reparing it.
In my case it was impossible for me to start the screen up with power button no matter how much I pressed it. The only thing that worked for me was to press the back of the phone just below the camera. So it seems like a hardware issue. But on the other hand, at times when I can't get the screen turned on no matter what I do, I'd turn the phone off and start again and the thing would start up like nothing happened. So while I'm pretty sure it is a HW issue, I'm not sure how a power restart makes it work.

For me I don't think that this is a hardware problem as it only started happening once I did the big upgrade from 4.0 to 4.1 and then it follows a specific pattern. That is three power button presses will always turn it on. Less frequently I also get a problem where the power button turns on the three lights on the soft buttons but the screen remains black. I then hit the power button to turn it off, and again to turn it on and the phone is back to normal again.
Is yours an international version? I bought mine an international version and had it shipped to Australia.

solved?
Hi - did anyone ever solve this? This is happening to me with my HTC desire X after having had the screen repaired, so I think it is hardware related, but the shop doesn't know how to fix it! My screen also does not turn back on when I want to end a phone call and pull the phone away from my face anymore. These problems seem related as they started at the same time. I would be grateful for help!
