So after finally fixing all the other issues i had with my phone (broken screen, broken vibrate motor, broken speaker) i was finally at ease. It lasted for about a week with everything functioning until now the phone gods have again struck me down. This time i have what is referred to as a Power Cycle. Kind of like a boot-loop except the phone completely boots up into my homescreen then the power options menu pops up, and no matter if i click back or not, that **** is going to reboot on me. Its to a point where if i pop in the battery the phone auto boots. Here's the kicker though. If i take off the back case and just set it on the battery with an open back, it doesnt power cycle. But the power button on the case itself is not stuck as you may be thinking as i can depress it and the cover spring pushes it back. I've hard reset, even went back to complete stock (no root) and it still does it. the power button works (very sensitive) if you have no case on the back, but if that thing is on, it acts like the button is being pressed.
Any Ideas?
Sounds like the power button is stuck... Try taking the phone apart and cleaning the contacts. Then press the power button a few times to ensure it works like it is supposed to. Put everything back together, tighten the screws but don't torque them. Should not turn on after you put the battery back in, wait a few to make sure it doesn't. Then power it on and see how it goes.

still didnt work. i used some rubbing alcohol and a lint free cloth on it. the interesting thing is, when you take the case off, if you set your finger over where the button is (making no contact) it still registers that you are touching it. this is what i think is causing it to power cycle when the phone case is on, as it believes that it is being pressed when it isnt.

I had almost the exact same problem with my Epic Touch. Ended up being a bad power switch. How handy are you with a soldering iron? If you're pretty good, you can buy the switch for ~$10 and replace it yourself. (You can also try cleaning it - several tutorials here, and the "Captivate" phone seems to have the same switch and issues. Search both forums)
Several eBay sellers sell the switch you'll need.

My money is on a hardware failure. Do you have a stock ROM ?
hey yea i went and unrooted and reinstalled my carriers stock ruu....still same problem.looks like taking it back to the shop for them to fix
Hey actually exactly one week ago my Desire started the same exact thing, and I could not find help anywhere. Best info I can find is that it might be moisture, but at least for me I don't think that is the case.
I ended up taking the whole phone apart (been taking stuff apart all my life, but i was still nervous) to clean it out since I've had dust in the screen for a while... I think I cleaned it out pretty well, but did not take the plastic tape off the button. This did not immediately help, but after playing with it for a while it now works most of the time, but is quite sensitive usually.. the button "presses" before it mechanically "clicks".
Anyway, If you were to become desperate enough to try this, I would recommend pulling that black plastic tape off the button when cleaning, then stick it back on. Good luck
I've been lusting after the Sensation anyway
yea im not into pulling stuff apart that i got no idea about...took it back still under warranty n its getting sent in for repair...now stuck with a piece of **** samsung omina icon....windows phone sucks the big one very hard...ill be going back and asking for at least an android as a loaner while its in for repair
ohh well that's good that it's still under warranty. I was actually using the camera at a beach during hurricane Irene and that night the power button went berserk.. continuously turning the screen on and off... before eventually just staying "pressed" all the time again. So maybe the moisture theory isn't all that far fetched in my case (I was at a beach the first time it happened, but never went near the water)
Currently trying to get a broken Desire on ebay to harvest for parts :/
Moisture - Htc Desire Power Button.
Hello,
I've met with that problem.
I've unscrewed the device, I've remove the black tape, and I've used a cotton swab to clear it.
But the problem was solved, but later withing the 24hrs, It's back to auto on/off without pressing the button.
I would like to know, Should I remove the yellow transparent tape on the button for cleaning?
Thanks.
I just got my Xperia play today and notice that I can hardly feel the button being pushed down (power button). Is this supposed to happen? First time it worked fine, but now it won't even work (e.g. to turn the screen on etc).
Should I give it a few days to see if it wears in, or return it? Thanks
Fully agree with you on this. I got mine yesterday and the button was sticking. There must be some sort of knack to put the battery cover on.
Would filing down the plastic be the answer? Seems a bit odd to resort to this when it should just work.
If it isn't working now to even turn the screen on, you should return it and get another, the sooner the better . Mine works fine, always some response from it.

I've got the same thing ; resorted to keeping the case around the power button slightly open - works fine like that.
Well what I meant was that it was so far stuck down that pressing it had no effect whatsoever. Even if I tried to use my fingernail to dig into the button, nothing happened. It returned to the normal state after pulling the back cover and put it back again, but after a bit of mashing the power button round, it got stuck and became useless again.
I was thinking of filing the back cover a bit, but I might as well return it instead.
I've just got mine unlocked (via Jinx13) so I'm loathed to return mine now. Let me know how the filing goes

This happened to mine too.
It resulted in the button acting like I was long pressing it when I was simply tapping it.
It seems the top of the button was getting stuck on the casing, I flicked it off the casing a few times and haven't any problems in a while.
But still, seems an issue.
I have a similar issue or had. I was able to wiggle it free gently.
Noticed it was the hard case protector I bought for it.... It's temporary for now until my skin comes then will go caseless.
For the past week or so, the power button has been flaky. Sometimes I would have to press a couple of times to turn the phone off (not shut down, just turn it off).
Other times, the screen would seem to turn on all by itself.
Then a couple of days ago, I turned the phone face up and it was in HBOOT, waiting for a command from me. I had turned it off about an hour earlier and laid it face down so the screen lighting up with an incoming call wouldn't distract a meeting.
Yesterday and today, things have gotten worse. If I tap the button to turn the phone off, I get one of several responses. Nothing happens, or the phone turns off then turns back on a couple seconds later, or I get the power options menu as if I were holding the power button.
Sometimes the phone will just spontaneously turn on with nobody touching it.
I have kept it in a silicon case the past two years that keeps dirt out of the controls. I wash the case at least weekly and make sure there is no cruft buildup in it or on the phone.
I have tried using a duster can to blow out around the power button. Sometimes it seems to help momentarily. Other times there is no effect at all.
Anybody ideas or suggestions?
Of course, it could be due to the fact I fondled a Razr Maxx the other day...

Mine use to do that because it would get stuck against the cut out for it in the back cover. I just took a file and made the cut out where the button fits slightly bigger, and all has been well since. Good way to test is to leave the battery cover off, press the button a couple times and see if it still gets stuck.
I took the back of the case off yesterday and tried a few times. Results were still random.
It almost acts as if there is something down inside the switch itself.
Thinking seriously about going online and activating the Boss Lady's old DInc and using it for a few months.
I had this same problem with mine a while back. The screen would turn on at the slightest tap and if I tapped the button to turn it off the power menu would come on. I wound up taking it to best buy and collecting the insurance policy I had on it, refurbed dinc was the result. It seemed to be an issue with dirt/dust in the power button.
If you don't have insurance and are willing to void any warranty you may have crack it open and take a can of compressed air to it... but this should be your last option.
dusty!
It definitely has grime underneath it.Use a can of compressed air or an air compressor tank with air gun to blow it out. Smart-phones don't take kindly to being taken apart.
As I said in the OP, "I have tried using a duster can to blow out around the power button."
So disassembly and blowing out the case did not work.
What DID work:
Saturday night, gave up and ordered RAZR MAXX.
Sunday morning (and ever since), no problems!
Hmmm...
I had a weird thing happen. Earlier today I dropped my phone from approximately 18 inches onto a laminate surface. The phone was in a protective case. After I picked it up, the power button wouldn't work. The rest of the phone was fine. No scrathes on the case, no other types of hardware failure or signs of damage. I opened the phone up, removed the motherboard and inspected the entire system. Everything seemed perfect. I inspected the power button and there didn't seem to be an issue. I put everything back together, while paying close attention to make sure that all connections were secure. After reassembly there was still no change. So I have a couple of questions:
1. Can I jump the connection between the two power button connections (which I believe is how the power button itself normally activates the phone) to see if that's where the problem is so that I can establish if the power button is in fact the problem? Or will that short something out on the motherboard?
2. Has anyone had anything like this happen, or know of a place where the power button can be bought, etc... Any suggestons are appreciated! =)
Thanks!
Edit: I was able to find the connections to the power button flex cable. The two terminals were loose and I was able to pull them out a bit using a wooden tooth pick. I now have good contact and the power button is working perfectly. I recorded what I did and will post a video on YouTube in case someone ever has this happen to them. I don't know why an 18 inch fall would cause this type of issue, but oh well. Fixed is fixed.
I have enabled Pocket mode and 95% of the time it works great.
But every once in awhile, I'll pull my phone out of my pocket and go to unlock it but it brings up a screen that says "Pocket mode is on" and wants me to press randomly appearing spots on my display to prove that I'm trying to unlock it.
Is this a known bug or do I need to try a factory reset?
My screen is clean and my case is a semi-minimal case and I've rebooted. It's been going on for a long time now.
This happens to me also sometimes with the original carbon bumper case. It happens when i pull out my phone quickly while pressing the power button, but the top of the phone is covered with my pants.
You can trigger that if you cover the ear piece with your hand an try to unlock it.

So, maybe I need to be slower to press the power button after removing from my pocket? hmm okay thank you.
