Coincidentally to the Oreo upgrade received time ago, the phone has started re-starting itself and sometimes ends on a eternal restart loop, only broke if you long press the power button.
Thought it was Oreo related so flashed it back to nougat, same behavior, thought if it was battery related but it does it while plugged too.
Watched it closely and I think is related to the actual power button, got to see the power menu in it once before it restarting, is like it just go and sets it depressed by itself.
The SMMI test does not have a button test, is there any low level hardware test that support button usage/monitor?
TIA.

Post this issue on ASUS ZenTalk Global.
I guess it's a hardware issue. Is your phone under warranty?

Thanks for your response, it is not under warranty anymore, is a shame because device is working awesome otherwise.
I am facing the same issue. Please provide me any solution.

So I'm having a bit of an issue. Had my nook for a few months now with relatively no problems. After upgrading to the new u-boot and .32 kerneled CM7, however, I noticed the power button became finicky. At first I thought it was software related, since it happened as soon as I upgraded, however I am not fairly sure it is hardware related. Frequently after pressing the power button to turn the screen on, the power menu pops up as if I held down the button. Often, it eventually powers down like I held down the power button. Furthermore, if I apply pressure near the power button, it acts like I pressed the power button. Needless to say, this sucks. So my questions are: is this most definitely hardware related as opposed to a software problem? And if so, is there any way to fix this by taking the nook apart? Or am I completely screwed? Any help is greatly appreciated. Thank you!
My wife is having the same issue on her NC running CM7. I am restoring it to stock now to see if the problem continues. If it does, I'll try to get it repaired or replaced...
I'll post back once I'm done and have had a chance to test things out.
I hate to bump this but did either of you ever get a fix? Mine's having the exact same issue...
Mine had a similar problem, but the power button completely stopped working after I applied an update. I had to send it back for a warranty replacement unit, which was a pain to deal with!
Similar issue but with the "n" button.
Yesterday I have updated my TF101/US to 9.2.1.17 (not rooted, serial B50) and now my power button does not work at all. I cannot either shut it off (I can hold it for minutes, nothing happens), nor can I wake it up (the only possibility is to plug in the power). Reset to factory setting does not help
I talked to Asus, they suggested to send it to RMA, but I want to try to discharge it completely and check whether it helps.
Will keep this post updated if I find out something more.
Update: battery discharge did not fix the issue. Going to send the device to RMA.
Thanks for this post, this if for no other reason is why I will be dealing with my random reboots (they only occur once a week or so, if that often, for me so not a big problem, not like a broken power button would be) rather than updating the patch. However, this belongs in general or Q&A not development
Also for me you have to call assistance for a RMA: i could understand that power button does not turn off screen, but i can't understand, a part an hardware problem, how it does not shut down keeping power button down or why it does not turn on.
Yes, that sounds like hardware issue, but that must be very weird coincidence.
The complete story is that I just received device from RMA yesterday (LCD backlights were broken). I turned it on, it happened to have ICS already (it was sent with Honeycomb) and I was able to install all my software. Then a message re. new OTA update poped up, I decided to upgrade, and right after that power button stopped to work.
Yes, that can be hardware issue as well, that is why it goes to RMA. If I were 100% sure that this is software issue, I would wait some days hoping that ASUS will release bugfix for it.
Hmmm..the device will not power on if it is shut down? (How would you know this unless you shut down, and then can't turn it back on I don't know).
I re-read this and it is unlikely IMO that a firmware update could break your hardware, but I guess if a computer virus can break nuclear centrifuges anything is possible? Could be a coincidence..I feel for you, I had an over-discharge issue one night and my TF didn't want to boot up, and then flashed the red battery on the screen, but for those first few seconds my heart wasn't beating..I get the same feeling when I get a bad flash too lol
Luckily, the device wakes up when you plug the charger in. So, currently my choice is either to keep it running (disable sleep) or to have a charger and plug the charger in when I need to wake it up.
The bad thing is that the RMA "cycle" takes about two weeks.
Maybe it isn't a coincidence..

Mine started this about two weeks ago before I picked up the update today... I thought i was the only one until I saw this post
I have misunderstood something: post says WAKE ON not TURN ON, ok this could be software related, but long press power button should be FORCE A SHUT DOWN...
Click this link on how to remove the front bezel. Then you can check the inside power switch to see if it's working:

That's the way I fixed my TF101 after I dropped it and the power button got stuck in the chassis.
Also read this thread:

I think this is a solution to your problem, if it's not software related, which I doubt.
I get the same problem all the time, I leave it sitting for a couple hours come back and it won't turn on or off...
I also sometimes get the non functioning power button. I cannot consistently replicate it.
Sometimes it happens after it sleeps for awhile.
Sometimes it turns on when I open the tablet up while connected to the dock.
I have to hold the power button until it reboots itself. This is annoying after while. And even getting more so.
I'm also having a power-on related issue since the ICS update but didn't want to start a whole new thread for it. Ever since the update my Transformer boots into CWM by default. If I power it down completely then press the power button the EEE Pad logo flashes on the screen, I hear an audible "click" (best way I can describe it) from the device and it boots into CWM. If I select "Reboot device now" from the CWM menu it boots right back into CWM.
The only way to boot properly now is to hold the volume down/power buttons until the menu comes up to choose between Android and recovery and choose Android. (It actually defaults to this so I can just let it sit 10 seconds or so)
Any ideas?

exactly same problem as me now. holding volume down and power is the only way to start it up if it has been left alone for awhile. since the update.

Apparently it's a pretty common issue with the new version of CWM, as explained in this here thread.
So far the only solutions I'm seeing involve ADB commands or flashing a custom ROM.
fixed for now....
I had the same issue the power button would only cold power off the device. The only way to power back on is by connecting the charger.
I solved it for no in the following way which i do no recommend to anyone. I have opened the device and disconnected the battery for 5minutes. After connecting it back the device powered on with the power button as it should.
In my opinion it looks as if there's some power related controller that was "hang" and ignored the power button .
Any ideas ? Asus ?
It seem that my TPT is shutting itself off more and more often.
Sometime just like that, sometimes when charging.
I can't figure it out.
It also seems to take longer and longer to get the "buzz" when restarting.
Any thoughts??
Thanks
My TPT is rock solid. Not one reboot yet.
As you are observing longer and longer times for powering up this could be start of a failing power button. It is a quiet common issue
I've already had my mother board replaced.
Took about 2 weeks, no charge.
Looking at some of the complaints, not too bad.
Here we have IBM doing Lenovo guarantee work.
I hope it is not the power switch again.
I think it is something else but do not know what.
No reboots at all here. A few forced closes but no reboots. Maybe the forthcoming ICS from Lenovo will work out most of the bugs.
Maybe try installing a log app. You can try inspecting the things that happens right before the shutdowns.
Mine started doing the same and I sent it in for repairs. New mainboard was inserted and it took 5 working days.
I suggest you do the same, agian..
I don't know the laws and regulations of your country. But here, in Denmark, if they can't fix it by 2. try, you can demand a refund.
Same issue here, but I don't think that it shuts down...I suggest that it's more like falling in a deep deep sleep. Everytime it happens, I have to force a restart (press the power button for 10-11sec.?) But sometimes it wakes up again, after holding the pwr button for 2-3 sec. Just tapping the botton doesn't help too often.
And everytime it happens, the WLAN is on. If i turn on the flightplane mode, it won't shutdown....pretty strange..
Send it in for repairs. It's a systemboard issue. Mine was replaced and the issue was gone.
Hey,
I've searched this forum on others but haven't found anyone who've had my problem.
I have an original GT-i9500 purchased a little over a year ago around the launch. The phone was rooted and had a custom ROM installed. (Crash ROM). I have installed the ROM about 3 months ago, and haven't fiddled with it recently. I've had CWM installed.
Yesterday I've noticed that the device went into boot loop all of the sudden. I haven't done anything unusual when it started boot looping.
I can see the Samsung logo for a couple of seconds, but then the screen turns off and the logo comes again. Loop. Trying to enter recovery mod (CWM) doesn't work. Phone keeps looping. Trying to access download mode does work partially. I can get to the screen where it says "Warning!!" and asks to click "volume up" to continue. But stays on that screen for a few seconds and then boots to the logo again. Happens whether I click "volume up" or don't.
I have no idea what caused this. But shortly before it started I did see that an app that uses wanam was updated (bubble UPNP) and there was some notification about it from wanam.
any help would be greatly appreciated. Thanks!
You have eaither a malfuntioning power button, a faulty battery or some other hardware failure.
This is not a software problem.

I have exactly the same issue, tried plug in power supply, shows an empty battery icon with circle in the center, stays for a few seconds and screen goes blank. It repeat this process if i keep it plugged to the power supply.
Just an update in case anyone ever finds this thread and is experiencing the same symptoms. It was indeed a faulty power button. Having it replaced has solved the problem.
It was apparently stuck on "pressed" mode (not physically, i would've noticed that). Another indication for that was that putting in a battery would automatically turn the phone on.
i know it was before a few months back,
but anyway... i got the same issue too, but my phone was on stock rom without root.
this is random annoying issue...
as i understand from you guys, i will need to take the phone to a lab to fix this, bummer!
thank you any way...
same problem here..
just got this issue today.. cant go in download , cant go in recovery, wont boot...
i was using it just fine when it just turned off...

Faulty power buttons, faulty power buttons everywhere.
I fail to understand how samsung does this. This has been like the 500th stuck power button issue here.
Looks like we have to add it in the guide.

I've got my phone back from the repair service and it was indeed a failure of the power button electric circuit,
(i don't know exactly how to translate it correctly to English, but they say something about secondary electric circuit board)
anyway, it been replaced and the phone came back to live again
I got it fixed today..
I think it should be added as a major cause for bootloop, if you cant open recovery or go to download mode
at first i thought my phone was bricked but then after some hard searching i found out this thread and proceeded accordingly..
I opened up at the phone and checked the power button myself with my instruments.. then i took it to repair center and told them to replace the power button... simple as that.. cost me 9$

Thanks for the clarification! My S4 has been doing that for a while now- think I'll take it to the repair center and get it checked out.
I have same problem
I just bought a used XA2 that appears to be in excellent condition. Problem is, whenever the screen sleeps either after timeout period or tapping the power button, nothing will get the screen to come on besides holding power and volume up buttons which reboots the phone. I have yet to set the phone up as I was checking out functions before I did all that. Bootloader is still unlocked. Did a factory reset several times and software repair with Sony Companion, nothing fixes it. The phone is still on. I get hepatic feedback when I press camera button for instance. But nothing wakes it. Power button functions normally as a power button. Used to be you could wake a phone by tapping the screen twice but there is no option for that on this phone. I've searched online with no luck, and I've found nothing on XDA. So just throwing it out there in hopes someone has some ideas. Last resort is I send the phone back, which is an option.

1st of all i am really feeling disappointment that xda is no more like past days forum now, i remember few years back xda was the home of resolving issues, but now i am seeing here that nobody have concerns with other problems..
Anyway bro for you my suggestion is to perform Xperia tests in support app, run all tests and specially ear proximity sensor test, i don't know why but i feel its an issue with proximity or any other sensor which is related with display, most probably its proximity or light sensor, run the test and see the results, if that test show you any problem with a particular sensor so it means its a hardware issue,
As you mentioned you performed hard reset and software repair as well and nothing had changed for you after this, so definitely its not about software but its a hardware issue,
Run these tests, it will show you the reason behind..
Phone went back to seller.

Still rooted. The problem was present before that.

Hmmm.. in that case i don't think so its a software glitch or firmware error, its your hardware issue, but i will never suggest you to disassemble your device by yourself, the device is in warranty or not is another thing, even your warranty gone void due to rooting the phone, you have to give it to sony service center to resolve this particular issue, don't do anything by yourself and don't give it to any cell phone technician to repair.. although its not good to even assume but i think its to be batter to change your device after repairing, hope things get better for you.. :good:
