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.

Problem..Volume itself goes up. Please Help

I have a MDA 3. I am facing following 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 up 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 up and stays up there.
When I try to decrease volume, it keeps going up right after I decrease 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 MDA 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.

If HR does not help, 90% chance that you have some hardware problem - stuck key, short circuit or broken connection from keys to the mainboard.

[Q] Screen wont turn on after it turns off. ATT Tilt 2

Everytime I boot my phone up, it works fine up until when the screen goes into sleep mode. Once it goes into sleep mode I cannot turn the screen back on, it stays black. The keyboard, end and answer key lights show up when I press the power button but the screen just stays black no matter what button I press.
I end up having to either take the battery out or using the stick to press the reset button on the side in order to get the phone to where I can see the screen again. I have adjusted the settings to where the screen doesnt go into sleep mode and the screen just stays on but that drains my battery. I want to be able to have my screen go off so I can save power but if it goes off it wont come on again until I reboot.
I have done a hard reset. This problem started happening to me when I started using the Energy Rom but I've even flashed different Roms and the problem still exist.
Somebody please tell me what's wrong! I need help! This is a big annoying problem to have. Thanks.

is this problem occurring when you slide the keyboard out?
i had the t-mobile touch pro2 with this problem.
the screen would die when the keyboard was out and not come back.
if this is the case, what i did was...
well. obviously not open the keyboard fully.
but if i accidentally had.
instead of pulling out the battery, i waited...
till the screen 'naturally' went to sleep.
than i would pull out the stylus or press power button
and the screen would come on.

Yes the problem still exist even when I slide the keyboard out. Once the screen goes off, that's it....pressing the power button to get it out of sleep mode, sliding the keyboard, I press all buttons and nothing works. The only thing that "works" to get the screen back on is removing the battery or using the stylus to press the reset button.
When sliding the keyboard out the keys light up but the screen doesn't come on, also pressing the power button lights up the end and answer keys without the screen coming on.

so. whenever the screen goes out, period, you cant get it back?
or the screen goes out and cant get it back once you slide the keyboard out?
if it is only when sliding out the keyboard...
try not opening the keyboard fully on the right side.
on my rhodium, after that point, the screen goes out.

Yes, period. Also, you know when you put your face to the phone during a call and the screen goes off so your face wont press anything on the screen? It doesn't come back on from that either once I end the phone call, it just stays black. I'm assuming you don't have any other suggestions. This Sucks

This has to be a software issue but I don't know where to start. I'm surprised nobody else has encountered this problem. I've grown frustrated of this issue because I don't understand why it's doing this. I have had the phone for almost 6 months only dropping it once 4 months ago and it wasn't a strong damaging drop that would affect anything inside. I guess I'll just have to go last resort and call warranty to swap the phone out. Thanks for the help.

Same problem

My phone also dos not come back on, when I put it in out the sreen with the power button on top, or when the phone goes to sleep. Nothing can put it back on(opening te keyboard, pulling out the stylis, presing the answer-, windows-, back- and end button). I and up using a music players too keep the phone busy what's makes it operational. Cant really remember when this started happening exactly. My phone is at the moment loaded with a standard ROM. I used too have a custom ROM.

My TP2 does this too, although I only encounter the problem sometimes when someone calls. I answer and put the phone next to my ear, the screen goes black as it should and the phone just dies. I can't hear what the other person is saying and the screen wont turn on anymore. I have to take out the battery to reboot.

set light sensor to manual in settings. You have some bad or fragmented code causing the problem. Pretty common actually, many different reasons, but usually either a bad light or proximity sensor or software issue. Setting the sensor to manual should do it, if not, hard reset and allow the phone to fully set up before touching it, to allow full customization process to complete. Search my posts on SOD (sleep of death) for more information.

Funny this was brought up. Now im worried I just dropped 250.00 and have a new one coming.
Mine started with the ear piece quit working. couldnt hear anything except on speaker.
Anyway I started having the screen issue over a month ago, only way to get it back was soft reset with the stylus. Also when the screen was lit, I couldn't hit the power button to turn the screen off. At times the screen would be on 24/7 and I just dealt with it. The times when it decieded to go to sleep was when I needed the soft reset. Well long story short I forgot my charger one day at work and the battery died. after pressing the power button for hours with no response, moving the screen in all diffrent directions as I pressed the button.It came on once after hrs of messing with it. Well today it died again and I am fed up with it so out came the tools. Once I opened it up I noticed the ribbon that feeds the screen from the mother board was worn and torn. the ribbon slides everytime the keyboard is slid out and it rubs on both sides of the phone. I thought maybe mine was just a fluke and was installed wrong considering the phone being 10 months old but now I read this and see maybe its a common problem. The cheapest I could find the Ribbon was 56.00 so I didnt want to chance it not being the issue.

Major Catch 22 - Desire got Wet now have 3 issues! PLEASE HELP

Hi guys.
So i managed to get my desire wet/damp and whilst it still works it has developed 3 issues:
1) The weirdest of all - the phone wont go into standby, as soon as you press the power button or let it timeout the screen goes off and they instantly turns back on to the lock screen. If i leave it, it will timeout again on lockscreen and come back on, it does this forever. I have done factory resets etc, all the same. Weird right. As i result i would like to reflash the mod and see if that fixed it as assuming its software related (somehow).
2) Volume keys do not work - think means i had issues getting into recovery. Finally found a widget to do it and then....
3) Trackpad does not work in recovery so i cannot re-flash or try any new rom to see if that fixed (1)
Proper catch 22
Any suggestions appreciated.
Thanks
Bridgstfer

Install 4ext touch recovery.

Update after installing touch recovery
OK I HAVE AN UPDATE:
The plot thickens but i have managed to S-OFF my Desire and eventually install Clockworkmod Touch which obviously doesn't require me to use the trackpad button so I was able to use Recovery. I wiped the phone and tried reflashing the ROM i had been using (Insertcoin) but this made no difference, the phone still keeps waking up immediately that it goes to sleep (either with power button or by sleeping timeout).
So i decided to install a completely different ROM (CM10_VJ_4.1.2_v3.0) and this installed fine. Now the phone will go to sleep and stay asleep if I press the power button. Problem solved I thought!
Now when the phone is asleep 50% of the time, trying to wake it with the power button will cause it to reset immediately and goto the white HTC screen. When it restarted it sits on the unlock screen and keeps timing out, screen goes off, then immediately on again - weird. If i unlock and lock with power button it will behave. For some reason the Search key will wake the phone every time no issues. Only the power key to unlock causes it to reset. Phone is sleeping according to Battery info.
Any other suggestions for what I could try. Could this possibly be something hardware related now? If there a way i can log the key presses or reason it wakes/resets?
Any help really appreciated, the phone is pretty unusable with this reset issue now.
THanks
Bridgstfer

theres a few videos on youtube, if it was me i would take the phone apart and clean all round the buttons. mite solve it. But as it got wet, the water could of damaged something in around the trackpad r power button, hense always waking the phone.

Thanks mate. So i tried this and installed CM7 today and have discovered something. As i said above the volume down button doesn't work and the volume up only works with some persuasion. Once i installed CM7 the problem where I lock phone with power key and it instantly wakes up now persists (on the JB rom it at least stayed asleep but reset if power button was pressed again).
However whe i changed the display timeout to 15seconds i watched as it timed out and instantly woke then noticed the volume would increment down one notch each it woke up again. This leads me to think that rather then the volume down not working at all it is actually stuck down permanently and could be causing the issue here. Is there any way I can find out if this is the case and disable the volume keys through software or do i need to open up the phone and disconnect it?
Thanks for any help - i think we are getting there!
Bridgstfer

I actually worked out that the trackpad is being pressed down constantly too because on CM7 when i disable trackpad to wake the phone actually stays asleep. Stil the phone resets if i try to wake with power button though, must be something to do with the button combo being held down.
Is there any way to disable both volume and trackpad buttons at the kernal/system level?
Tried button remapper but does not allow to remap the trackpad press.

With a file explorer, go to
system>usr>keylayout and modify bravo-keypad.kl.

I'm just back from holiday where my Desire had a ten-minute swim in sea water!
Naturally it was stone dead when I remembered it was in my pocket as I waded across an inlet which was supposed to be ankle- deep but was over 1.5 metres in places
I thought there was no point in drying it out without first removing all salt so (minus battery and cards) held it under a tap for several minutes then left it to soak in tap water in the sink for 30 minutes.
I then dried it over gentle heat for a few days then tried the battery. The vibrator ran continually and the white LED flashed randomly but nothing else. After another two days drying it booted - but only into Fastboot and the vol switch didn't move the cursor. But after another two days - it worked almost perfectly! The vibrator is dead and the screen a bit streaky, but all the other sensors work just fine and it's quite useable.
I had been logging the hike using My Tracks and it actually shows the course going a short way into the sea.

do you have an assurance or warranty?
if yes-->change phone.

Thanks for this. I actually got an app that let you remap the keys but it does not let you do anything to the trackpad click button (which is now the one stuck down). See photo of whats in my bravo-keypad.kl file here:

Any other way i can disable the trackpad completely. Perhaps at the kernel level?
Thanks

Problem with power and volume down buttons

Hi everybody,
I have sometimes a strange problem :
- the volume down button doesn't work anymore.
- I can't use the power button to turn on / off my phone, but it works as I can press it 3 times to open camera. On the contrary, I can't use it to ask for reboot, but it works for soft reset! Aaaaaarrgh! Brain pain!
When I try to soft reset, my phone enters in safety mode, as if I pressed the volume down button during restart.
In bootloader, I can't use power and volume down button. Quite annoying.
Sometimes, volume is turning down without pressing any button.
But what is weird is that my phone shifts from normal state (all buttons working) to defect state and back to normal state again without doing anything. It's unpredictable. It can work well for decades, then stops working fine for hours or days then back to normal.
Sometimes, when it works well, when I'm using it, it goes wrong without doing anything. I'm reading my favorite site and volume is suddenly going down. Without warning, without even touching a button.
I have to say one more thing. I picked up that phone from a coworker, and the volume button is a bit bent near volume up (picture needed?) but it worked fine for months before starting to mess.
I hope you'll be able to help me.
Sorry for my English, it's not my native tongue.

Seems to me like a hardware problem.
What I'd do honestly is to hit it repeatedly on a hard surface, but please, do not do that
If you can I suggest taking it apart and making sure all the ribbons are firmly set in place and undamaged. It can be an one way ticket for damaging the phone for good though, so wait for other suggestions too.

Thanks for your answer.
What is making me angry is that it also does this when left alone on the table : I let it there working perfectly and when I pick it up again, it fails.
And when it fails, once again I let it alone and suddenly the volume goes down, without even touching it. Raging.

its a hardware problem, u have to change the volumes and power flex, had the same problem with the powern button, i turn the phone off, and a few secons later it power on by himself till i change the flex

Did you take the phone apart recently? I had my battery replaced and that's when my Volume up started phantom pressing. I hit the phone repeatedly on a flat service and made sure to kind of slap it so it would impact kinda evenly as to not dent the case, it worked for about a week at a time, then I just took the phone apart and tried to align everything and made sure all the insulation tape was flat and and not bunched up and now it's fine. We'll except my USB port has got some giggle to it. Order a new USB of amazon for like $9, I'm trying to hold out for a LG V30
