Hello, I'm having the famous Cappy lock button problem (the one where said button doesn't work). It's not a physical problem (unless a contact has died somewhere on my motherboard) because my button feels the same as it did the day I got this phone. I've also never had any kind of problem with my power button before. I did get my phone secondhand from a friend which voided the warranty. The only way I can turn the screen on is by plugging it in or removing and replacing the battery. The only way it turns off is by timing out.
Help guys, I need some answers!
Thanks in advance.
P.S. I already tried the camera app trick and to no avail. I also can't do anything in recovery mode because the power button is also the selection button.
My button started acting up. I used a can of compressed air to spray into the edges of the button, and it's been working great ever since.

This is All very helpful, but I don't think that it is a hardware issue. I'll try all these things that you have suggested and we'll see to certain.
When you take the battery out then put it back in does it automatically turn on? If so the power button needs to be replaced....at least that's what mine and a lot of others I've seen was doing.

It's a hardware issue. What else would it be?

just disassemble it and clean the button. I had same problem on my volumn down button.

I took it apart and the motherboard was surprisingly clean. I was expecting it to be dustier, but everything looked fine. I'm now thinking it could be a micro-fracture on a solder contact. I still haven't sprayed keyboard cleaner directly on the button, so maybe I don't have to buy a whole new motherboard.

Did you replace the button yourself? I have been without my lock button for about a year now and I have kind of gotten used to it, but if the process of replacing it is fairly simple than I may just do that myself! Also where did you purchase your new lock button?

The power button suddenly quit working today. I left it in my grandparents car while we were in church (boring) and after church, I tried to turn it on, but the power button didn't do anything! So when we got home, I plugged it in, then the screen came on as if nothing was wrong. I tried pressing the power button, but nothing happened. Is there any way to reboot it without the power button (and no I am not rooted, I'm keeping my tablet stock, unlike my DInc )? Do you think it's a hardware (button) problem or a software problem? The button clicks when you press it just as it always has, so I don't know what the problem is
Thanks in advance
Sounds like black screen of death. Nothing serious, just hold power button for 10 seconds, then start it again and it should be fine.
Otherwise root and flash netformer 1.4r2, which may or may not fix the issue.
I already tried that. Lol. The power button itself isn't responding to anything
I had same problem yester day in school. I put my transformer on the desk and nothing else. When I wanted to turn it on nothing happens. In house i put the power cable to it and it worked, but power button isn't working...
You can probably find a widget or three that will allow you to reboot.
DO you have ADB setup? You can ADB reboot.
RMA time?
Mine had the same problem shortly after I purchased during the summer. I ended up having to send it in to be repaired under warrenty. According to the repair sheet they replaced a daughter board.

No one can help you except Asus. Sounds like you need an RMA.
I had a similar problem with my volume button exactly two weeks after getting my Transformer. I promptly returned it to Best Buy and exchanged it for a new one. Luckily I was still within my return/exchange period (by the skin of my teeth).
I now try to avoid using the hardware buttons as much as possible. I use the audio manager app to control the volume and plug the device in to turn it on (I try to use the power button as little as possible). I'm not rooted so I have to use the button to turn of my device.
Those buttons always felt a bit flimsy to me and I see it as the biggest build quality issue with the Transformer.

You don't need Root to have a screen button to turn off your TF.
All you need is the free app 'Screen Off and Lock'
It's an excellent App with a lot of amusing tools for switching the screen off.
I have it installed on my non-rooted Samsung Galaxy SII. The Market says it is compatible with the TF.

Yeah I I'm trying it out. I clicked on your thanks button.
I'll eventually root my TF and try out an app that will allow me to shut down my TF without using the hardware button. My TF is a B7O but I think it an early rootable version.

You should find one back to you.
Just letting you know that my power button died while the unit was still quite new. I ended up having to send it back for repairs to the dreaded Texas center (at my cost I may add) but they got it back in about a week and it seems to work, at least for the time being. Between that and having had to have my dock repaired this has been the most problematic tablet/computer I have ever owned. It is actually a pretty nice unit in many ways, but build quality seems to be pretty abysmal. What worries me is that if it has so many problems when it is new, what will it be like when it has a bit of age on it? This has also prevented me from rooting it until the warranty is over, since if something like this goes wrong and you can't restore it to stock they won't fix it.
I had the same problem after I got a new cover. The power button did not do anything while in the cover, when I took it out of the new cover the power button works perfectly. The new cover has magnets for closing it. I belive the magnets were causing interference. Everything is good now.
Hey ya all
Ive tried to google for this issue but haven't found anything. I got it yesterday evening, about 1-2 hours after OTA update to 2.3.4.
So what happens is when I hit the on/off button to turn of the screen, it sometimes goes black for about half a second and then turns back on. Same when I try to wake it, goes light and then goes dark. So it seams like a dubbleclick almost.
Sometimes I've also got the issue that my Home button just keeps making screen shots, took me a while to figure out thats conected to the power button. How am I supposed to take a screenshot? Could it be a simple hardware issue where the button gets stuck? I've tried to remove the backcover and clean up, but it all seams fine for my untrained eye.
How are you holding the phone when this happens? This same thing happens to me sometimes if I kind of wrap my hand around it when I pick it up. I unconsciously hit the volume button like half a second before I hit the power button, and the volume button wakes the phone & then the power button turns it right back off.
It can happen whatever way Im holding it im afraid, and it has only occured since last night. Lets see if someone else got this after 2.3.4 or if its just a wierd coincidence.
And also, as I said, it seam to bug out my screenshot function.
That's not a coincidence, happens to me as well.
My guess is that's because of the new screenshot feature (hold Power+Home). Can anyone hazard a guess as to how to turn it off?
Well, guess it's a good thing it aint then, hopefully it'll get fixed.
No one else with this issue? It anoyys me alot
I have this issue, but it only happens if I press the button too fast or something. I don't know how to explain.
happens to me too
Randomly enough, just tried the screenshot function and it said saved to Camera folder but it's not there. What app is used to take it? Someone said it was MySketcher but I don't know
I spoke to HTC support sweden today and they didnt seam to be aware of this issue atleast. Keeps happening to me about 30% of the times i hit the button.. I dont think its hardware issue but didnt care to factory reset the phone yet.. Anyone of you with the issue has other than stock rom? Did it only happen after you upgraded to latest firmware? Ive only had it since 2.3.4.
I'm getting this exact same issue since upgrading to 2.3.4. I have a stock ROM too. It's really annoying, press the on/off button and it doesnt always turn it off, it does exactly the same as what the op says.
Also getting it take screen shots when I press the home button.

Was abit tricky to understand you, well anyway, so you had it repaired then? Id love to avoid that, hate being without the phone. But maybe thats the only solution.
Thanks for your input.
Yea I'm not so sure if this is a software thing. I haven't experienced this during regular use, but I have experienced a double-press effect while in Clockwork Mod. If I press the button on the leftmost part and do it slowly, I can get a double click without actually clicking it twice. Scares the crap out of me when I'm flashing roms and kernels.
So maybe something is up with the power button itself? Too sensitive maybe?
same issue here, was afraid it was my button. first i thought it was crt animations that were causting it. i have to go in to build.prop and turn off power+home screen shots because half the time i hit home it take a screenshot. not sure what's up with the power button.
have the issue on both bulletproof and eaglesblood, both 2.3.4
Happens to me as well and drives me absolutely insane.. The problem is definitely hardware.. I got a replacement back cover under warranty and after two weeks the problem is back just as bad.
To somewhat remedy the screen off/on flicker, i use 'screen off and lock' for long press of search button.. Not the same I know, but at least it doesn't flicker back on.
As for recovery, you can use home/menu for up/down, back for back and search for select.. I find this light years easier than having to ninja push the power button to avoid a double press.
I wish there was some way to fix the damn button tho.. I don't understand how HTC screwed it up so bad.

Having the same problem. Is the problem with the back cover or the phone itself? I looked at the button underneath the case and it looks bent. I was thinking maybe a tiny piece of paper inside would help, if it does, I'll report back
EDIT: playing with the button with the case off shows no problem. It has to be the way the case interacts with the button
EDIT 2: A piece of paper doesn't completely relieve the problem but does make it much harder to reproduce, and in my opinion, it's much nicer to press now
EDIT 3: Thicker paper=issue solved. I'll send HTC an email about it not reaching the button all the way, maybe they can do a recall on affected backings

I ripped off a little piece of paper from a paper cd case about the width of the button inside, I then folded it until I found the perfect thickness and set it on top. I just carefully put the backing back on. It pushes the power button up about double what it was. I'd take pics but all it is is a piece of paper sitting on top XD

Hi everyone, I'm having problems with my power button. Every time I press it once, the phone keeps recognizing that I clicked it twice--which results in a situation where its hard to lock my phone properly and awaken my phone (the screen also flashes multiple times in some instances). It's not the rom or kernel either... because I tried it both on Sky ICS and Chimera
Has anyone had this problem before? Will I need to replace my power button?
I was always worried that the power button was built like crap. I've never dropped this phone, it just became like this after pressing the power button so many times from daily use.
There were a couple of threads about a "sticking" power button causing havoc... turned out that a small amount of lint built up under power button... and a quick disassembly, cleaning, reassembly fixed the problem. You might try rebooting a couple times to see if it resets on it's own. Also, if you get it working again you might consider flashing a "wake-on-volume" key mod to take some wear and tear off your power button. I'm on SkyICS 4.2F6 and flashed Sean's modified android.policy.jar (wake-on-volume)... works to perfection. Good luck. Hope all gets resolved.

Thanks for the advice, that's what I was thinking. The rom I'm using already has a wake-on volume mod... I just have to get used to using the volume keys. I'll probably tear it apart sometime this weekend and see what I find.
Depending on warranty it may be worth getting it replaced also.
I I have a Samsung Galaxy S2 Skyrocket i727 (with stock firmware and ROM), i dont have a SD card and not too many apps installed either, maybe 10-15 apps at most. Today while the phone was in my pocket it just went into this continous reboot cycle, it reboots, gets to the AT&T splash screen and then reboots again and then this goes on forever.
I googled the hell out of this issue but cant seem to find a solid solution and hence hoping u guys can help.
I cannot get into recovery mode cause it never gets past the splash screen
I cannot seems to perform a hard reset (power button + volume key) , it just reboots again.
I tried plugging the phone and connecting via USB but it doesnt help either, it reboots before the computer can detect the phone.
Hope u guys can help ? life without android is no fun...

I had this same issue with my LG Phoenix, I tried the needle around the power button, and that popped it back to normal. Apparently I held the button down to a side and it got stuck even though the actual button part was in it's "normal," position.
However it did reboot several more times after I got it unstuck. I did remove the back & battery, & unplugged it. Let it sit for a few minutes, after that I put the USB cable back in, then pressed the power button, put the battery back in and pressed the button again, and it went through the normal reboot process.
Just wanted to give you guys an update that i started cleaning the part around the edges as some folks suggested and that failed. then tried smacking around and blowing air into and that failed. Then took the entire phone apart and cleaned it several times using different techniques and sad to say that it all failed and i m SOL.
Bummer but it is what it is and i was quiet happy with that phone.

Where does one find a power button for the skyrocket (the one attached to the motherboard)? The closest thing I could find was this:
http://mobiletechvideos.mybigcommerce.com/samsung-galaxy-s-ii-skyrocket-power-button-repair/
It is a repair service though and I live in Canada, I would prefer if I could just order that part. I have been to few repair shops that cant do anything because this power button is hard to find. I opened up the motherboard and the power button clicks fine, so I think it probably has to be replaced.
Freezing the phone
I had the same issue, came here and read all the things about the stuck power button and needing to replace whatever is beneath it. My friend works in aerospace and had told me about one of the things they need to worry about is temperature causing wire shrinkage due to temperature. For whatever reason, I decided to use that logic and throw my phone in the freezer wrapped in a dry rag. 30min later and the phone finally worked after 8 hours of the boot loop/no boot. That was around November and I haven't had an issue with it since (until today, but it is a different issue).

I have just fixed mine!!!!
There is a little battery on the circuit board when you take apart the phone. It looks like a small watch battery. Top side is and bottom side are opposite polarities.
I had the exact same symptom. Sometimes just pressing the power button momentarily would bring up the power down menu, then I knew to press it a bunch of times because it was stick. If I didn't eventually it would turn off and vibrate constantly. It kept getting worse.
I measured with an ohm meter and the button itself seems fine so I figured maybe the digital logic relating to the button itself is faulty. So I shorted the little battery on the board (do this only for a brief period, no more than 1s) and put it back together.
Its behaving perfectly normally. I was also getting weird artifacts during video playback before, kind of like what failing solder would do on a bga gpu. It fixed that too.
So I think its similar to that problem some laptops have, where it wont turn on until you remove the battery, hold the power button down a couple times, and then plug it in. It seems a complete circuit discharge fixed this problem at least for me.
If people are interested I can try to find a picture
removed link
In that picture its the silver shiny metal circle. To short it you connect the bottom soldered part to the metal plate on top of the battery. This comlpetely drains all circuits.
So I think a lot of these problems are caused by a phantom charge. In any sense, Im very very happy
Also this could explain why the fridge method worked. Cooling the battery can significantly drop its charge, however I would advise against the cooling method if possible.
EDIT: blah cant post links... if anyone needs the image pm me your email

You'd need to find a friend or local electronics repair shop, but I ordered some here:
http://www.etradesupply.com/oem-samsung-galaxy-s-ii-skyrocket-sgh-i727-power-button.html.
The buttons are $0.99 USD if you buy 2 or more ($1.05 CAD), but 5-7 day business shipping is like $16.99. Still cheaper than a replacement phone, and it's an easy fix for an electronics person or electronics/tv/computer repair shop... At the rate these power buttons have had reported failures, and for the price, I'd get a couple of them in case the replacement fails in the future...
If my wife keeps squeezing the power button on her phone when some crappy app she has wigs out, I'll be needing my second button sooner rather than later...
why when one person says it something everyone band wagons on that idea. i actually had the same issue my skyrocket couldn't go pass the "samsung" screen. all i did was flash a new rom or i just restored an old backup

Then it was user error or a bad flash. And that's software, not hardware.
Skyrocket power buttons are known to fail. I believe Samsung has even acknowledged this.
When your phone randomly goes into a 1-second vibration cycle, sometimes showing the reboot menu beforehand without pressing the button, more than likely it's the power button that has either failed or is sticking.
With my wife's phone, the button was not sticking, and usually lightly tapping the phone at the right angle on your lap or the counter would break the vibration cycle and let it boot up, until the next random power button press and vib cycle would happen.
Button replaced, same exact ROM, and problem gone. :thumbup:

I have a repair shop and i fix these issues with no problem. the only issue im located in Puerto Rico. when the power button gets stuck is because of heavy use, a fall or something that makes a lot of pressure to it and the copper contacts inside the button stay making contact. this is know to happen to i727-i717-i997-i897 and some other galaxy s1 s2 models.
i attached the picture of the power button.
its half way down.. i can lightly touch the power button and it will turn the screen on/off.. really becoming frustrating. id like to fix this on my own. any one been through this and have a fix? if i send it back through insurance, will it be completely covered? thank you.
Sounds like the tab the battery button connects to is either broke or simply undone itself. Taking the phone apart is the only way to find out.
