power button not working

I have a problem with the power button on my desire, the phone wont switch on.
I have taken the phone apart but cant see any physical problem.
The phone still charges ok.
Is there anyway to get a stock phone powered on without the power button.
Does it sound like it might be a faulty flexi cable.
Or any other advise.

you might need to take phone to repair center sounds like something a phone repair ceter can fix , i dont think there is a way of turning on the device with any other button ( i think it's possible if you changed it if you rooted but in your case i dont think so) does the cable near the power button look burnt out or loose , did you drop your phone ?
btw what are your usage patterns ?

The power button is hardwired. You can change the function of hardwired buttons using software, but software needs to be running/on to do that. You cannot use software to redirect the function of a hardware button with the software not running/off.

I have managed to switch the phone on using the usb trick, and the power button is working. Guess i will be ordering a new flexi cable

sounds like you need a new device

[Q] Help! Vol - button broken & stuck in bootloop

The Volume- button has been broken on my Desire HD for ages, but this has never been a major issue until today: I got stuck in a bootloop and I don't know how to get into recovery mode!
Please does anyone have any suggestions either on how to get the vol- key to work or on alternative ways to get to recovery? I tried "adb reboot recovery" in cmd.exe but I get error: device not found.
I am worried my phone is broken and I can't afford a new one, so I would be infinitely grateful if someone could give me a hand!
EDIT: I managed to temporarily fix the issue by pulling off the volume rocker and strongly pushing on the button underneath with a pin, but I would still like to know if there is a way to change the key combo that allows to boot into recovery (as my temporary fix might not work next time).

In short yes, I encountered this during a re flash where it said, menu or back disabled.
There is a way just can't recall what I read on here about an alternate button setup.
Running cmw for recovery + version?

So you used another recovery?

If the physical button on the ribbon cable is still good...take out your battery, remove the s/n etc sticker carefully-all the way, you'll see a ribbon cable under it about 1/4 inches wide leading to the vol button-use a small plastic twezzer or the like and gently lift the cable and volumn button strip up and out of the slot-it is not fixed in place. Now you can put your battery back in and use the vol buttons with your fingernail. Awkward but for a one time fix in an emergency-it will work. When fixed put it all back--maybe once out you will see the real issue with your volumn not working. Maybe the strip got out of it's position some way.. Of course if the physical buttons are damaged or the ribbon cable is ripped, this will not work.

Hello,
I didn' use the vol buttom in my revocery, install 4ext revocery and than you can with a spedified application start in recocery mod (rom manager for exemple).

I have the same problem with the volume keys. I can't boot into recovery without using ROM Manager... Is there another way?

This worked for me when I had a similar issue. Got it repaired though as I was under warranty (had to convince the repair folks that it had stock though )

[Q] Power button hyper-sensitive

Hi all,
I've had some problems with my S3 power button. It's behaving like it's being pressed when it isn't. Just slightly brushing it, without depressing the button, is registering a press. Pressing the button is behaving like the button is being held.
I've read a number of possible fixes. I tried software options, just to be sure (cleared cache, factory reset). But this is almost certainly a hardware problem.
I stripped the phone down and the physical button itself looks absolutely fine. It is interacting as it should with the internal button on the motherboard. The issue seems to be that the internal button attached to the motherboard (the little white button) is registering clicks even when it's not being fully depressed.
The phone did have some water damage about 6 months ago. I wonder if this could be causing the the phone to mess up now?
I even tried a fix that many people seem to think works: smacking the crap out of the power button itself. It had no affect on my phone - I think that "fix" that is for a power button that is stuck depressed and not a power button registering phantom clicks/being hyper-sensitive.
So I suppose I have the following questions:
1) Has anyone else experienced similar problems and, if so, did they get it fixed?
2) My plan is to try replacing the motherboard/logic board and see if that helps. Does that sound like the best fix or is it overkill?
3) If I'm replacing the motherboard, does it need to be an I747 motherboard or will any S3 model work fine?
4) What's the best source for a motherboard? I don't mind if they're used or refub so long as they work.
Any advice you can offer is welcome.
Cheers.

I had the exact same problem with mine, and unfortunately there's not much you can do about it as it's a hardware defect. I haven't tried replacing motherboards or anything, so that might help you. What I did to help with the problem was rerouting my power button to my volume up key so that I can use the power button as little as possible. The only time I use the power button now is when I need to power it on - which causes reboot loops sometimes.

Sucks.
I like the sound of your work around, though. Was it pretty simple rerouting the power button?

Ditto, my power button is borked too. Ended up doing the same thing but I don't use my power button at all. I just use rom toolbox to reboot system/into recovery
Rerouting was simple for me as it's baked into the settings in the rom I'm on (ground zero) as it is with most custom ROM'S I've been on. If you're just running stock I'm sure there's an app in the market that'll work however I'm drawing a blank ATM

I'm running CM.
I've had a look through the routing options. What I can't locate is a way to disable the power button completely. My main problem right now is the phantom clicks. I'd rather that button be dead.
Anyone know of a way I can make that happen in CM?

Nevermind. I just physically removed the power button. That did the trick.
For anyone interested, you can replace a faulty power button on the motherboard pretty easily and the parts are cheap. If I wasn't due an upgrade in 4 months I'd probably do that. No need to replace the whole motherboard.

Does anyone know the app to reroute the button? I too have the same problem.

[Q] Power Issues... Even in recovery/download mode

Phone randomly turns off/reboots (mostly reboots). Sometimes the phone won't go past the "SAMSUNG" screen on boot. I booted the phone into recovery and download mode multiple times but it'll reboot after a minute or two.
I've tried another battery and still had the same issue. I've removed the battery and held the power button down to discharge power. I've opened up the phone, blew the dust out, and made sure that the power button was not getting stuck. I'm fairly certain it's not a rogue app causing the issue, but I've factory reset the phone to stock.
Please advise!

if you have a sd card, sometimes a funky sd card will cause this as well. remove yours for a while to check if its causing your issue

Sounds like the same problem I was having. Take your finger and lightly move it up and down over the power button.. if it acts up or reboots it could be the button issue..

I was having the EXACT same issue. I thought it might be the recent upgrade to the cm11 nightlies since before it was once a week but now it's just non-stop. Is the issue the actual power button switch or the plastic buttons?

For me it was the power button itself.. Read my post on how to fix the issue yourself if you dont want to take your phone into Sprint
http://forum.xda-developers.com/showthread.php?t=2679936

Fixed (kind of )
I've taken my phone apart before to replace the speaker/audio jack module after my headphone jack stopped working in one ear (also a common s3 problem). I did as suggested and added a piece of paper wedged in between the button and the button switch. Surprisingly the switch was perfectly clicky so any problem will have to be internally such as corrosion or just worn out. The problem seemed to have been fixed (kind of, not really) as the phone turned on and wouldn't freak out when I rubbed the power/hold button. I got all my data off the phone successfully. The buttons themselves are pretty cheap online but I don't want to have to solder considering I have an upgrade. I'll just get an S5 whenever they are available. Thanks for the help.

I'd like to thank everyone for their suggestions. I determined that it was in fact a power button issue.
My "FIX" (for anyone with similar issues):
Temporary:
I removed the logic board from the phone and flicked the button up and down and that helped a little with the button's hypersensitivity. Because a slight tap would make the button "stick" and power off, I took apart the phone and physically removed the plastic power button. I could hit the button if necessary with a small screwdriver or my watch strap thingy, but I did my best to keep the battery from dying out. As for dealing with a lack of "lock" button, I installed an xposed module that let me remap my volume up button as a lock button.
Permanent:
My mother recently upgraded her phone and gave me her S3. Unfortunately it had a cracked screen. I removed her logic board and swapped it out with what was in phone and reactivated her phone as mine.
Thanks for everyone's help, and hopefully this can help someone else too!

September Security Update (#11 - R16NW.N950USQS5CRI4) bricked my phone

Anyone else experience this after the most recent security update?
My phone rebooted after the update was installed, and the notification that the update was completing was visible in the notification bar. Then the screen timed out, since I wanted to let the phone just do its thing while finishing the update. The screen powered off, and it has been stuck that way for two days now. I've tried all manner of button presses to simulate a battery pull (Verizon officially recommends pressing and holding the volume down button and the power button to simulate a battery pull), but none of them work. I tried all combinations of the button presses with the sim tray pulled out, the charger attached, but nothing seems to work. I don't get any led indication either, just a black screen. I've tried charging it for a couple of hours, but don't get any red LED or other indication that it's charging at all. I think it's fully bricked, but wanted to know if anyone else had this happen and had any suggestions before I take it in for service.

An update really shouldn't cause that.. How long have you held the buttons for? If you have a case protection on your phone take it off and then press the power button the Bixby button and the volume down button and make sure you have them all squeezed good and try to hold it for 2 minutes or more and if you still don't get anything then plug it in and then try again holding the buttons for at least 2 minutes.. If that doesn't work then you might need to have Samsung fix it for you under warranty if you still have warranty available..

You're right, it could be a coincidence, but one heck of a coincidence. If no one else is experiencing the issue, then it must be my phone. I tried holding the buttons for two minutes both charging and unplugged, no luck. Thanks for the suggestion though. I'm off to Verizon to see what my options are.

If the phone has been with you less than a year, Samsung will repair it for free since every phone has a 1 year warranty from the date of purchase.. Get a hold of Samsung and see if it's under warranty if it is they'll give you a shipping label and you just send it they'll fix it and send it back..
