Power button does not respond at any point.
*EDIT:except after battery out for a long time, then power button WILL turn the phone on, but then continues to not function as per usual.
However, the phone automatically turns on as soon as the battery is placed in, so it's not dead at least.
Also can not get the phone to be recognised on either of two computers (one running Win 7 and the other Vista) always get "device has malfunctioned etc"
Have re-flashed a ROM from SD but same problem. If holding down the Vol Down on start up (putting the battery in) I can get to bootloader, hence the re-flash. But holding down both gets to the hard reset 'warning' screen, but it won't let me press Vol Up to actually do the hard reset.
All in all a frustrating problem which means I have to remove my battery to turn my phone off and have to use the option from Windows Menu to lock the device.
Any help with any of the problems is greatly appreciated.
Also Power Button mechanical function is still normal.
Many thanks.
Sounds like your end key has become faulty as well as your volume up button. Both of witch are common issues, especially the end button, but most peoples volume down button wears out first. This is do to the fact that the end/power key is in constant use from turning on and off the HD2 or from getting MAGLDR to pulled up a bootup for those running NAND Android. Also the volume keys take a lot of wear and tear from constant volume adjustment especially if you listen to alot of music on your HD2. Plus the volume ..down key takes extra wear and tear from being used to enter bootloader.
hello
hello vsem
Yes it does seem that way, however I have had teh battery out over night, when I put it back in this morning it DID NOT automatically initiate the boot sequence. But it did after I pressed the power button, so it must have read it to some extent?
Also when the phone is on I can change the volume up and down as per usual, its all a bit strange.
Any other way to initiate a hard reset other than that menu?
Thanks very much!
It seems you are having a hardware issue, try sending your device to the service centre.
UPDATE: This remapping allows the Genius button to "act" like the power on button while your phone is on. Having trouble getting it to actually turn the phone on. Any thoughts?
Dead or dying power button on you MT4G? Mine was dying suddenly and i didn't want the hassle and risk a warranty exchange and get a phone with a bad eMMC chip or screen. Also didn't want to pay $100 to get the power button replaced.
Using the guide found below, I just remapped my Genius/search button in hopes it will become a power button (UPDATE: as of right now, it can only act to shut off the screen and to power down the phone--powering on the phone via the remapped button doesn't work yet.)

The only difference: by key 183, replace FUNC_4 with POWER (all caps).
like when you press the genius button, it turns the actual phone on/off...or just the screen on/off? if it turns the phone itself on/off, thats pretty cool as my power button was getting a bit unresponsive also. you could also use the trackpad to wake up the device(not sure if all roms have this feature tho). but either way Ive never thought of this little mod, reps to you
I've tried remapping Genius and Camera (I know, potentially lose a factory reset option), NEITHER of these will act to power on the phone. They'll power it down and shut the screen off, but they won't wake up an off phone.
Could it be that the power button is the only button capable of turning the phone on (based on hardware wiring and $hit?).
I've tried swapping Genius and Home buttons...they work perfectly EXCEPT for as a way to power the phone on.
I've also read that you can power up the phone by plugging it in and holding down the home button. That doesn't seem to work for me.
There must be some other code that would make this work...
Thank you for this. With the TPU case holding the power button to power off the phone is a little strange. Cant tell if im pressing the button too hard or not. I do not want to press it harder than I need to cause I know how fragile they can be. Now I dont have to worry about it!
Getting a replacement
The remapping POWER is surely helpful to some...and prevents wear on the pitiful power button.
But with no clear, definitive way to turn my phone on, should the power button completely die (which seems like it will this weekend...it's worse each time), I'd be f*cked.
I did the web customer chat with T-Mobile to get a replacement. They offered me a Samsung Galaxy S. I declined that, saying I want a MT4G or better. They responded that the MT4G is out of stock and they don't know when, if ever, if will be available. This waste of time was about an hour.
So I CALLED customer service, explained the situation, the rep looked in their systems and talked with a manager and said they have *limited* stock of MT4G. My guess is that when something is *limited* they can't give it out as an exchange. Anyhow, this rep put in the order, making sure they had the MT4G in stock, and wondered why the web chat people said they were on back order. This CS experience took about 15 minutes.
Should have a replacement MT4G next week--hopefully good screen, good chip and good power button.
This is only my second exchange.
ANY changes to the power button behavior in the ROM are in effect only when the ROM is up and running.
You can't do ANYTHING to make the phone turn on using another button when it's off, without reworking the HW.
i suspect the power/lock button is FUBAR, but there are some other symptoms that do not resemble just a bad power/lock button. here are the symptoms that indicate it is the power/lock button:
1. when the phone is off, almost impossible to turn on. sometimes have to press and hold power button 10-12 times before it will shut on
2. when the phone is on and i press the lock button to lock the phone, most of the time it thinks i held the button and says "slide down to power off" although sometimes it doesn't respond at all. it almost NEVER locks when i press it (like it should be doing)
3. when the phone is on and i press the lock button to unlock the phone, most of the time it shuts off completely and i go back to step 1
symptom that indicates another problem not related to power/lock button:
1. if the phone is off and i press the power button, when the phone responds it will sometimes say "samsung" like it is turning on, and then nothing else will happen. i won't get the ATT screen and it won't boot up. this some times happens multiple times before the phone finally boots
currently i've been letting the phone time out automatically instead of the lock button, and using the camera button to unlock it. i've also been trying to not let it turn off at all, because getting it back on is really tough.
is there anyway i can disable the lock/power button...and/or is there an alternative way to lock and turn on your phone that doesn't require the use of that button? even if i tell myself not to use it, there are still times in your pocket where the darn thing gets pressed. for me that could mean it kills my phone and doesn't restart for the rest of the day, which i'm sure you can imagine is not ideal.

You seem to have a (hardware) problem with the power button (obviously).
There are a couple of ways to turn on the phone/display without the power button:
- camera/back
- connect power charger
- usb connect
Last 2 are not practical and first you already do. You should try and see how much would it cost to replace the power button, if you're out of warranty. Should be cheap, and beats workarounds.
is there any way to lock it rather than letting it just time out? what about turning it on?
do you feel pretty confident that the seemingly unrelated symptom where the "samsung" screen comes up and then shuts off while trying to turn the phone on STILL indicates the button is broken? just worried this problem extends further than just the button.
thanks for your help.

There's no other way to turn it on (except plugging it to charge) and you found the one workaround, with the camera.
I am *very* sure that the power button is the culprit in your case, most likely the spring that pops back the button is either broken or out of place.
If you keep the power button pressed, in 2 seconds you'll see the slide message, but if you keep it pressed, then it just turns off after 2 more seconds. So, yes, it's the power button and nothing else, in your case.
Fix that and you should be back to normal.
And you're not the only one with this problem. Recently, I've tried to help someone else here, with the same problem, as you can see here.
thanks. i called around and a guy here in town said it will take him 30 minutes for $30 to fix it. i'm taking it to him at lunch, so hopefully i'll come back with a fully functional phone--he also was pretty certain it was the power button, and had seen this before. thanks for your help.
well it wasn't the power button. apparently there is a battery connected to the power button that is dying. but you can't even order a new battery, so pretty much once it's dead, it's dead for good and you have to do the camera button workaround like i was doing.
though he did solder the battery to the board a little more (that's another problem, from the factory it is soldered to the main board so even if you could replace it, you'd likely damage the board), and it seemed to fix the problem. he claimed it would only be temporary and within a few weeks the problem will likely come back.

That is weird indeed. I don't think I ever heard of another type of battery being used in phones, tied to buttons. Unless it's a capacitor but anyways...
Thanks for sharing the info with us!
I know this is thread is almost a year old, but unfortunately, it seems my Samsung Focus (v1.3) also has the exact same issue.
The worst bit is that every other aspect of this once glorious phone still works and I was very happy using it, not really feeling the need to upgrade.
I was using a custom ROM which I flashed back to AT&T original 7004 but that did not work. It doesn't seem to be a software issue at all.
The symptoms are the same - tapping the power button to lock the phone gives you the option to slide to power-off and after a second it will do that anyway (without any interaction). When you try to boot, it won't progress past the SAMSUNG screen and in the rare chance it does boot, it will work for an hour or two before dying again. Connecting power helps a little (as you can't turn off the phone with mains power connected), but only just. I have tried using the original battery which I initially suspected was causing issues but even a generic battery has the same issues. I'm tempted to spend $20 on a genuine battery but I don't think it will really help given the generic battery did work properly when the phone was itself.
I'm now faced with upgrading to the Lumia 920 but with new models around the corner I think I'm going for the budget Lumia 520 which has similar specs to the Focus (except LED flash) and will hold out for the new flagship model, or buy the 920 when it falls a bit more.
Hi - just wanted to add my experience with this issue (as my focus exhibited these exact symptoms today). Unlike some people, though, even if my phone managed to boot up, it would shut down again after a few seconds on the tile screen.
Like cysser0, I also suspected the battery at first, but replacing the long-life I had purchased last year with the original battery (which I keep charged as a back-up) had no effect on the symptoms. To be brief, I tried all sorts of things over the course of an hour. Nearing the end of my tether, and resigning myself to try a format as a last resort, I discovered that if I held the power button and the volume button down, I could get the phone to stay on. Releasing either of these buttons would result in the phone switching off suddenly.
Wrapping a rubber band tightly around the top of the phone has allowed me to continue using the phone for the moment, and I have managed to do a backup of all my content (not that I will be able to restore it on this phone, it seems).
This is my very first post, so I hope you can forgive me for any mistakes.
I buyed an secondhand ZUK Z1 from eBay. Everything was fine and dandy.
But after a week I encountered a problem. Firstly the Volume Down button did not respond properly then it utterly stopped working.
I buyed spare parts (side key) from the official ZUK-Store.
These are the contacts to connect with the "motherboard"(?)
I opened the the Z1 and even replaced the side key contacts myself.
After putting everything back together and powering on, the Volume Down Button still didn't work.
Volume Up button and Power-Button works perfectly but Volume Down does not...
I can press the Button normaly and hear the *click* noise.
I guess it's either a manufacturing error or some Software detecting error. Or something burned up inside. Well I don't know.
I can't access to recovery without the Volume Key. So yeah... i'm pretty frustated.
I'm typing this to find others with the same problem and would appreciate it when somebody knows more.
The device is not rooted
ROM: CyanogenOS 12.1-YOG4PAS60J
Phone struck
I too have the same volume down key problem. Because of that the phone enters boot menu and it becomes very difficult to come out of it till the phone shows some mercy on us. Once by chance if it works then the phone works absolutely normal. But it is a potential problem.
I've tried
http://forum.xda-developers.com/oneplus-2/general/guide-oneplus-2-home-button-dead-t3324321
none of the solutions worked while I was on Seraphs CM13.
There wasn't any on-screen buttons even in the buttons menu, so then I decided to flash Oxygen back on it because I know there was on screen buttons. After getting Oxygen 2.2.1 back, I tried to call *#808# and it would just lag and nothing would show up. Now the phone keeps restarting on it's own, power button doesn't make the clicky sound anymore however I'm able to feel when it's pressed down and I'm not sure if the power button is the cause of it. Not sure what to do from here, should I just contact OnePlus? It's been several months with my phone.
Same here
The home button on this phone is a capacitative one, it should not make any clicking sound as it's static.
Probably your home button and/or IC circuit just died for you like many others (me included). I swapped the button myself, as I'm pretty used to repairing phones myself, but that alone didn't fix the home button so it's probably the speaker IC or flex cable going up to the mainboard that's gotten fried by static electricity through the button.
