HELP!!! Power Button Not Working!!!!

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.

I meant actually shutting the device off, is in powering off. But thanks, it will be a useful app anyway.

Ahh... I see. Hope you find the App interesting anyway. It does have quite a few comical methods in switching off.

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.

Good luck with the root and many thanks for the Thank You. Each vote comes in handy when my surgical team check my votes at the end of each week.
My wallet then goes into hiding.
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.

Weird problem with volume buttons

Hello my volume buttons seem to be defected (when I press either the up or down key, the volume on my sensation goes up, then a split second later goes down again so I have no way of lowering and raising the volume. This happens even when I take off the case and just press the buttons on the main unit.
If nobody has any suggestions I think it best I take it back to HTC to get fixed. My phone is rooted and using Revolution HD rom though so I'd like to return it to stock. My CID has been super CID'd to 11111111 however it originally used to be HTC__053 (Thailand).
I have attached a screenshot of my software information - could someone please recommend which stock rom to flash from here?:

I had the exact same problem a few weeks ago after driving through a rainshower; a reflash of my mod unfortunately didn't solve the problem, so I think you are experiencing the same hardware failure I had.
I managed to solve the problem, but for doing so I had to open my sensation and during the process destroy the "void"-label which sits on one of the screws. As I suspected a water damage because of the rain I was driving through before I didn't hesitate too long to take apart my sensation - my warranty was gone either way for me.
If you don't want to risk damaging your phone or losing your warranty you might want to keep your sensation the way it is now. I also kind of arranged myself with the situation before I decided to have a look at the inside of my sensation and actually repaired it succesfully.
If you press one of the volume buttons, the volume might not change, but the volume slider appears and you can change the volume by dragging the dot to your desired volume level. By drawing all the way to the left you have set up complete silence. If you want to turn to vibrate mode, you can press the volume-down button once. For me this worked quite well and I was able to set all volume-levels and modes without any problem.
But as having my sensation in a state it should not be quite bugged me I decided to have a go and try to solve the problem. I watched the tutorial videos available on youtube and saw that the volume-buttons are sitting on a separate board. I then took away the back plate and released the upper mainboard. After that I could pull out the volume-buttons-board, blew off the dust of it and reinserted it. After these steps both volume buttons worked as intended again. So if you think you have the required tools and are a bit handy in taking apart expensive stuff you might consider doing the same as I did.
Of course I want to emphasize that if you decide to take apart your sensation I will in no way take the responsibility for neither any damage that might happen during the process nor for the void warranty. I also can not guarantee, that what worked for me will work in your case.
If you only use the volume buttons for changing the volume (and not for rebooting in case your sensation freezed or starting in bootloader mode) you might consider learning how to live with the new "feature" of your sensation as I described in my third paragraph

Yes I've been using the method you described, tapping a volume button then dragging the volume on the screen. I'd quite like to get it fixed though and I'd rather not void the warranty - my device has been plagued with problems and I fully expect something else to go wrong with it in the future in which case I'd like to keep the warranty. Also the HTC service centre is literally round the corner from me so its not a big deal to get it repaired!
Could anyone please recommend which stock rom to flash my phone and return it to its original state so I can take it back to HTC?

I have started having this problem today. No water damage or anything, it just started happening. Tried re-flashing ROM etc but no fix as you said.
I really would like to try to get it working properly again and I'm sure I could do this as I used to be a wiring tech for an electronics company. I'm just hesitant in case I fluff it up.

I'm experiencing the same issue with my volume up button, I can 'click' the volume up command but it is not recognised. The funny/annoying thing is that this happened to me before. Like a month ago, I had this same issue for two weeks, but then it disappeared. My guess is there's some dust or oxidation preventing the click to be recognised.

Stupid volume up press is being recognised again. I've tried to think of anything I might have done to achieve this but cannot think of anything. At least it was not the removal of the battery. I tried that but that did not make a difference.

Nexus 5 boot loop

Hi,
My nexus 5 constantly reboots at the google logo. I think it is a power button problem.
I bought my nexus 5 from the google play store but I do not live in the US, so RMAing it would be difficult.
So is there any way I can fix it? I tried tapping on the power button on the mother board but it didn't help.
Thanks!

I think your phone is soft-bricked... Try to boot into custom recovery, factory reset, and reflash a custom rom.

I have the same issue but I cannot get into recovery or anything else. There is not enough time before the phone reboots again. I have read of people having success but it seems rather rare. The strange thing is that I can press or tap (with luck) on the back of the phone, near the power button, and the phone will turn on. I am sure this is a hardware issue but I got mine from T-Mobile and my bootloader is unlocked and on Android 5.0. The bad thing is that I am now able to JUMP! and was looking at the Nexus 6... oh the humanity!
On an side note: When pressing on the back of the phone (see above) repeatedly I was able to get the phone to fully boot but once I quit it rebooted again. I have not been able to repeat this as of yet. I am leaving it on the charger and hoping that it will somehow right itself like other have reported... that is unless anyone has any suggestions.

I agree. I took the phone apart and messed with the components but nothing has changed. When I was able to get the phone to book all the way up "Power off" appeared as if I were pressing the button. I am not sure how to fix this.... I am sure that T-Mobile will not cover the warranty since it is unlocked.

it should be a relatively inexpensive fix at any local repair shop. or you can try repairing it yourself, can probably find a youtube vid about it.

I have not found a video, yet. I tore it down as far as I could but I will keep searching. I am 99% sure that it is hardware related but I don't think that T-Mobile will swap it out or let me use my JUMP! because of the unlocked bootloader. I knew I should have relocked it when I put 5.0 on it!!!!

you still can, its very simple. in fastboot.. fastboot oem lock. or if you have root, the boot unlocker for nexus devices app. you can lock or unlock the bootloader with the app, if you have root. personally, i dont think they would even know about the bootloader being unlock.

The issue is that the phone reboots about every 2 seconds making it impossible to make a connection through ADB, recovery, or anything else. I did, however, find a solution/idea on a post by "nadrojcote":
"For the last week or so my power button/lock button has been intermittent, sometimes having to hit it 5 times or so to get the screen to unlock. Yesterday it all of a sudden stopped working and I couldn't unlock.
I am making this post to share my fix I found for the problem. Seeing how my phone is not under warranty because I have already replaced the screen, I took to tearing it apart and seeing what's going on. Hoping I could order a new power button, unfortunately the button is soldered onto the main board. Upon taking it apart I realized I had put a little shim in between the power button and the plastic button in the housing as a "rattle fix". This is what I am thinking caused the problem, this caused me to be putting too much pressure on the power button and caused it to over time break apart the back of the actual buttons metal housing on the main board. I removed the shim and it still did not work. I was going to take the main board and heat it at a low heat in the oven in hopes to reseat solder points, but before I did that I tried using a fine pair of needle nose pliers to crimp the back housing of the button back together. Luckily this worked. Unfortunately I do not have pictures, but if someone else has the same issue you should be able to see what I'm referring to by comparing the power button to the volume buttons on the mainboard, there is a metal housing around the actual button that is soldered to the main board, it has a slit down the back side of it that allows it to spread apart. The volume keys should be tight.
THE PROBLEM: Power/Lock button stops working
THE CAUSE(assumed): Nexus 5 power/lock button rattle fix
THE FIX: Using needle nose pliers to crimp the metal backing of the power button housing good and tight.
I hope this helps others out in the future as I'm sure I wont be the only one with this problem."
Now, I did not have a loose power button and so did not mod it. I did however take the phone apart and pull the board out. On the back of the board, opposite of the power switch, if an aluminum(?) case which can be removed. Under this there is another aluminum housing with a circle in the middle of it. The circle was somewhat bent touching the board parts below so I carefully bent the circle up. Next I gave the power switch a few "gentle" taps and pressed the casing around the switch to hopefully make it tighter as was recommended by "nadrojcote."
As you can tell from my word use, I am no where near an expert on anything electric BUT my phone is now working. I have not put it back together yet but I am in the process of restoring it to factory and locking the bootloader in case I need to send it in. I have sent some major prayers to God today! (If you do not believe in God you don't have to say anything negative about my post... just carry on)

This happens to me always to restart device
There is a solution to this?

Nexus 5 restarting regardless of ROM

So I've tried factory wiping and installing a few different roms and no matter which one I go to I keep getting these random reboots. This is particularly troubling when I restore an older rom that I know I was not having this particular issue on.
It is making my phone pretty close to unusable since it will often go into an "Optimizing apps!" speil draining battery and taking an obnoxiously long time to reboot. Not sure what is up. Any suggestions?

Try with a clean flash (or the factory images) without user data/modifications and see if your RRs are still there.

The button will NOT seem to be stuck, even if it is, as the contact is made internally. My bro´s Nexus had this problem, and by the end it kept rebooting constantly because the button was making contact on its own. I fixed it by tapping vigorously at the area between the power button and the camera and that made it work.
A way to know if it is stuck could be to press the volume down key as soon as it restarts, if it goes into recovery, then there is no doubt the power button is stuck.
Don´t dismiss hardware problems, as many Nexus are affected by the power button issue and you already tried software solutions which didn´t work.
Hope you sort it out. Remember to use an app to avoid pressing the button so much, such as when waking the device. I recommend Gravity Screen, but there are many other options.

Holding down volume after one reset actually put me into recovery. Plus it's restarting at times in recovery now :/
I doubt it's under warranty since I got it in feb 2014 x.x

If you got it directly from Google, I'd try calling them up and asking for a replacement even if you are a few months off the warranty period, I have read some stories of them honoring warranties in order to get rid of stock. That'd be true even now that the new Nexus is supposedly releasing this year. Nothing wrong with trying, you might get a new, shiny phone.
That being said, don't worry, it's perfectly fixable. The part that gets stuck is not the button itself, but the part that goes into the motherboard, so don't bother fiddling with the black button. I managed to fix my brother's button by doing the following:
- Clean the area between the button and phone of debris or any dirt that could be causing it to be stuck. This is just to be on the safe side, as it is unlikely that it is the cause of the malfunction.
- Take the case off the phone if you haven't, and then put it upside down and tap vigorously with your fingers in the area between the camera and the power button. It might not work the first few times, but it eventually will release the part that is stuck.
- As soon as you can get it to turn on without rebooting itself, install Gravity Screen, or any other app that replaces the power button to wake up or turn the screen off. You are looking to use the button as few times as possible.
After doing that, his Nexus went for being unusable due to constant reboots to working fine. It's been almost 6 months since it happened so it is bound to work, just don't lose heart and patiently work at it. Tap a bit harder if it's not working. Let us know whether you managed to fix it.

Well someone mentioned maybe trying to clean it out somehow. I tried canned air and that didn't do anything so I formed a seal over the button using my mouth and then proceeded to exhale. It has yet to give me any trouble since then.

Had exactly the same issue, reboots over and over again, couldn't boot to bootloader without reboot...
What helped for me was something I read somewhere else, don't remember where, was knocking on the back cover between camera lense and the power switch, did it 4 days ago and it works since than..

Sounds sexual

You can take the back cover off, and if you are careful there is no sticker or seal that would tell google you have opened the device. It is difficult to pull all the way off, the vibration motor is attached to the case back and comes off with it so it would seem stuck. You just have to keep pulling.

Pressing on the area between the camera and the on switch seems to help a lot of people it didn't seems ot have much of an effect for me. While my phone hasn't given me issues since shortly after I posted this thread I'm kinda worried I'm one drop away from the issue coming back

Would this allow me to repair it?

Yeah but you'd need to unscrew a plastic cover that is inside the phone. Phillips head screws, jewelers screwdriver size. Depends on if its dirt or a broken switch though.

Sorry to disappoint everyone but this is a widespread problem that google is aware of fro some time now. It's not the power button but it's burried deep in the software and appreas to have popped up right after the Lollipop 5.1 up date. Check out all the posts on Google

While it apprears to be confined to the Nexus 5 I have had it happen with my nexus 4 just running stock L 5.1
I hope that casts some light on it

Weirdly enough, my power button works flawlessly on 5 and 5.1. Red 32gb from the google play store. I've opened the case multiple times and put Arctic silver knockoff heat compound in sloppily and without regard, no issues other than sprint screwing up their spark LTE rollout.

Sorry, I disagree. While some instances might be related to software, it has been proven that there is in fact a problem with the physical button getting stuck on Nexus 5 phones. You can check it online and will find lots of hits and even YouTube videos, most of them around the time before lollipop.
Best way to check whether it is software or hardware is to press the volume down key when your phone reboots by itself. If it takes you to the recovery, you can bet your cat that it is not lollipop's fault

So I'm suspecting that I have the wonky power button too but.....
I haven't been able to get it to go to recovery when pressing power down and I've defintely had a few restarts very recently.
More importantly, and something that I haven't seen anyone else post about; more often than not my N5 just shuts down. It's usually when I've doing something with the phone (today was flicking through my GPM library). I'll power it back on and it will boot cleanly and then (more often than not) power down again. Other times it will bootloop, but that's rare. It seems to me that if I let it boot up and then don't touch it for a while, it will stay up but I'm not sure that's consistent.
Anyone else seen or heard of the power button causing a powerdown instead of bootloop?

You will need to troubleshoot this the old-fashioned way. Have you installed any updates, apps, mods or anything recently?
Best case scenario would be that you flash a stock image without restoring apps, kernel or any mods. Run the phone for some time, couple of days or so, and be on the lookout for power downs or reboots. After that, you can try adding a few apps at a time and keep checking. If the phone reboots even with a clean factory image, then I'd have to say the hardware is faulty. Could be the power button, could be something else.
Try it out and let us know

Power Button won't wake up screen sometimes.

Hello!
After locking the phone, it happens that sometimes the power button won't turn on the display.
The button is still working, because it is possible to start the Flashlight (long press power button) or open the camera app (double tap power button, can hear the sound).
I'm using the latest lineageos 14.1 version.
Does anybody how to fix this?

I don't think so, because my display got replaced.

I'm afraid it is a faulty replacement then.

As ridiculous as that may sound i think it's a problem with your button, you will have to desolder this and resolder a new one. I used to have the same problem, button didn't work like 2/10 at first, and that rate kept increasing. With use and tear it kept worsening. I bought soldering iron and replaced the button, it now works freakin' great.

Okay that sounds strange. I can give it a try.

Now that i see this Thread again, it's far more likely that your lcd just died or partially did. Although if it turns on sometimes like your state, "that sometimes the power button won't turn on the display" it may be a bad teared down soldering on either the power button on the lcd pcb. Get it to a repair shop and ask for a check, if you don't mine you cant open your back cover and remove the screws so you let the motherboard pcb exposed, with a high quality picture we should be able to see if the power button is the problem or not.

aye, and? Mine was the same, it worsen upon the replacement, and within some days of usage, the flex cable had gotten damaged for good, the oneplus one replacement displays out there are crappy, mostly used, not well maintained, cheap ones, and they are not to be trusted.

I'm using a cheap replacement from ebay that I replaced myself,and I'm yet to see any issues with it.

most lcd have the problem. i got a lcd thrice now from different manufacturers had the same problem for some extent
digitizer works fine but lcd doesn't have good connection

My Nexus was also sometimes not waking with the power button. A custom ROM flash (Nexus4Ever) worked well, but still had the same problem. Probably related to this I would notice that when the phone did wake it was sometimes taking a few seconds to do it.
After some searching I found a solution under the lineageos forums -- search for BUGBASH-230 (can't post url here because this is a guest reply). Basically, you have to copy (copy them, don't move them) all tzapps files found in system/etc to system/vendor. It worked for me. There's no more delay in waking up and the problem has been gone for a week now. Before the fix it was occurring at least once a day. Try it.

I have same problem with you and this occcurd after change os nougat to Oreo 8.1 on my j7 prime

It's not the display
I have the same issue on my Nexus 7 with 14.1 installed. The mockingbird replies about it being a faulty display or power button are unfounded considering rebooting the device fixes the issue. Only seems to occur when it's been on for a while or has less than 30% battery.

Did anyone ever fix this? I see this on a few versions of Lineage. Disabling the lock screen in System Profiles settings avoids the issue, but then there's no lock screen!

Not The Display, exactly...
Just thought I would throw in my 2 cent observations. I have a Samsung Relay 4G (t699/apexqtmo). It worked flawlessly with its stock software / and official upgrade (I.C.S. & J.B). Once I upgraded to KitKat or Lollipop, the screen backlight would never turn on after waking the device on a single button push. The difference between these versions of android as it relates to waking the device can be found in changes to power management / wake locks code. I am not good enough to figure the ins and outs of this type of programming, but maybe this will give some hacker an idea of how to patch or work around this particular part of the firmware. Thanks!

Just upgraded form stock to LineageOS rooted and all....display wake up worked fine b 4 now i have this problem also it will sometimes eventually wake up but takes forever and many button presses

So, if anyone is till wondering about this, here is the information i believe to fix this bug, that is if anyone can integrate the change into CM KitKat and beyond for our sad old Relay. github.com/TeamApexQ/apexq/issues/24. Any chance this could be implemented through an apk?

Because I really don't want to shell out $$$ for an F(x)tec Pro
