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.

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.

Power button epilepsy o_o

Heya, i know this has info here and there but here's the deal:
The power button has gone soft lately, it was good but then it became really sensitive to touch "one touch to activate" which was cool, until it started pressing by itself, now when i click it to lock the screen it turns on again, and if i shake the phone or something it'll activate.
But now it goes on and off randomly, and sending me sometimes to the power screen i can even activate it by pressing against the body around the front camera.
any ideas what might be causing it (my guess it's a broken/displaced spring), and please if you have links/guides to fix the thing (teardown vids/whatever) i'll be most thankful ^^
i looked around but i want something specific to our device, thanks! <3

Hardware problem mate. Will need repair. Read about this sometime ago where a user had actually taken the DS apart and fixed a broken plastic lever under the power button that does it... but since the power button presses a switch directly mounted on the motherboard beneath, i'd suggest you refrain from doing this yourself unless you are fairly good with tinkering with electronic innards. I mean software is one thing to mess around with, but hardware has very hairy balls indeed!
P.S. Love the thread title!!

Trigger Reboot if frozen (3 Finger Salute)

I looked around the forum and could not find an answer. Basically, I'm looking for the button combo that will force reboot the phone. Sometimes, I get SOD (Screen of Death) and need to reboot the phone. I want an alternative to pulling the battery.....

I did read on a website that was talking about tips and trick, hold the power button down and it will do a soft reboot. Haven't tried it though, could be bs.

It's BS.....didn't work. Anyone else know how to trigger a reboot on our phone? My old Droid Incredible did it by holding the Power, Vol Down, and Menu key (I think)....I feel like this phone should have something similar. Nobody likes pulling the battery!

If the software is truly locked up, nothing is going to force reset it except cutting off the power source (pulling the battery). Be thankful we can do that on our phones, iPhone users have been dealing with this for years and have to wait for the battery to die.

Research those 3-finger salute methods. They truly are fail safes when your phone completely locks up. Devs describe it as the end all (battery pulling replacement). Although it might be considered a hidden feature on most phones, I'm sort of surprised nobody has discovered how to do it on the S3.

Friend's iPhone locked up, power+home for 10-15 seconds restarted it without issue. Also, if it is a 4/4s/5 it is easy to take apart so you could unplug the battery from the board if you were desperate.

I second this and we'll add on my RAZR when it locked up all I had to do was hold both volume and power (I think that was out). Having said that I don't get why you wouldn't just pull the battery in this'd phone.
Sent from my SCH-I535

I could pull the battery...and currently do when my S3 freezes. Sadly, doing this is rather cumbersome for my situation. To remove the battery:
1. Remove case which is tightly bound to phone.....I foresee repeated removal will harm case.
2. Remove battery backing from phone.
3. Remove small metal disc I've placed in between phone backing and battery. This metal disc is part of a Magnetic Car Mount I use (very slick). Placement of this metal disc is specific to avoid NFC issues.
Given all that, battery removal is a total PITA. I don't think I'm alone here.......I imagine the vast majority of people would prefer a button-hold combination to force restart their phone in the event of a freeze. I believe this is the very reason the method was created. Nobody likes removing their battery....especially after knowing other phones have more elegant methods of force restarting. Furthermore, I have a strong feeling the S3 DOES HAS such ability. It is just a matter of discovering what the proper combination is.....maybe its 2-button hold.....maybe 4-button hold....I just don't know. That is why I'm here asking.

I didn't mean anything by saying that, I forget all the stuff people have on their phones because I run mine bare. I'm sure there is a way to do it just seems like no one knows it. I'll say the one or twice mines froze up it rebooted itself after a little bit.
Sent from my SCH-I535

Before I bought the GS3 I had an HTC One S and the battery wasn't able to be removed. If you held the power button for like 10+ seconds it would force reboot the same way power + home on iphone forces reboot. It seems crazy to me that you can't do that on every phone. I mean phone manufactures have to anticipate phones freezing up every once in a great while. How do they expect them to restart? Expecting a customer to remove the case and the phone backing to pull the battery seems like a terrible way to solve this.

Just figured it out for you
Volume up, home and power

I've tried many button combinations with no luck, including the one aforementioned.

Haha, can't that get to work for the life of me. Took screen shots, turned up volume, brought up apps but no reboot.

You have to hold power, vol+- for about 5 to 10 seconds, to power down idk how to force a reboot. But this method is good enough for me. I use it all the time it works on tw and aosp Roms. Sometimes it powers down around the 5 second time and sometimes it takes longer ldk why, guess it depends on how locked up you are.

It is the iMagnet Car mount. The thing is amazing and not expensive. There is an extensive review thread in the accessory page for our S3 here.

It's weird that this function would be ROM specific. I specifically remember this function was a constant across ALL ROMS on my Droid Incredible. Pisses me off I can't perform this reset on CM10....then again, its still kinda phasing bugs out..so who knows.

Interesting, I tried all of the combinations given in this thread and they did not work. Of particular importance though, this three finger salute method is still reliant on software working to control it. I don't know how it is controlled in other devices, but if the software that controls it is locked up, nothing is going to reset it except for pulling the battery.

I did it just now by just holding down the power button for about 10 seconds. I'm running slim bean rom.

Didn't work on CleanROM 5.0. I would think if there is truly a software reset on our devices, it must be controlled separately from the ROM and should be the exact same combination regardless of what ROM you are running.

Sticky Power Button

Just got my white 32gb and out of the box it has a very sticky power button. Sticks all the way down almost every time I push it so the power menu comes up. Anybody else have something like this happen?

I'm having this happen actually. Did you find a way to pop the back off and fix it, or did you send it back?

Actually after about a week of usage, it worked itself out and was fine. Haven't had a problem since, so I'd say just give it time and see if the problem resolves itself like mine.

Not sure if you've made the choice to unlock/root yet, but if you have, I'd highly suggest installing a kernel w/ sweep or tap to wake features. Additionally, it's (in my opinion, of course) a good habit to utilize a widget or toggle that will turn your screen off w/ a tap as well.
Obviously, if you determine you've got a manufacturer defect w/ the power button, by all means replace it. But the less dependent you are on the hard buttons, the less wear & tear on them. More often than not, these buttons are the first to go the longer you have your phone.

Mine seems to have sorted itself out too. The button doesn't seem to have that satisfying click my Nexus 4 did.

Glad your power button got sorted out. Being a new phone, I would probably send it back, rather than crack it open, but that's me.
On another note... Personally, I haven't touched my power button in a long time. I use "Gravity Screen," which shuts my phone off when I put my N5 in my pocket and turns it on when I pull it out, It also senses the micro-movements of my hands when I'm using it, and prevents the screen from timing out, If I set it down on a table, and it shuts off (due to timeout), I only have to wave my hand over it to turn it back on.
This app literally changed the way I use my phone, which is why I sprung for the $2 (ish) pro version, rather than the free one I linked. I highly recommend checking it out.

I RMA'd my 32GB White because of this as well as a vibration issue.
Sent from my Nexus 5

After 3 RMAs (= 4 different N5s) I stuck with the last phone and fixed the (loose) power button myself because I was fed up with the quality.
It is really no problem opening a phone, especially if you have done it with a PC before.

Disabled power button but it reboots my phone if I touch it

Hello,
I have a Nexus 5 with Android 4.4.4 and CyanogenMod 11. Like always, it had been working really find untill today, when it started to reboot and entered in a loop. I found out that it was because the power button was broken and with the lightest touch, it would activate.
Searching through the Internet I found out that many people happen to have this problem. I tried to disable the power button editing a file that is found under /system/usr/keylayout/qpnp_pon.kl, where I had to simply comment the line where the power button was.
Now, if I click the power button it doesn't happen anything, like I was expecting, but after 30 seconds of clicking it, it shuts down and it reboots like if it was an internal error or someting similar that caused that reboot.
Is it possible that disabling it the way I did could cause any type of problem that made it reboot after touching it?
I know it's an internal problem or something like this because when I touch it, it doesn't lock the screen or show the power menu, so the button itself is kind of "disabled", but it keeps causing this problem.
Is it good what I did? How can I solve it?
Thanks!

I had the same issue unfortunately. My N5 is still at LG for repair and it's taking much longer than they told me. Which is good of course. Like most smartphones now though, a 10 second power button hold will forcefully reboot the phone. It's hardcoded in the phone and no matter how much you try to disable it through the OS it won't make a difference until the rogue button is physically taken off the motherboard. If you're in Europe though and your phone is still in it's 2 year warranty I would strongly suggest flashing a factory image, relocking and calling LG (or Google, if the device came from Google).
Hope this helps.

Well... It's been like three years since I bought it, so I guess the warranty is over...
And if I want to disable it, I will have to do it manually and disconnecting it of the motherboard, am I wrong? I guess I'll either have to live with this problem or buy a new phone... Today it's not my lucky day! Hahahaha
Anyway, thanks for your reply!!

Many owners have the power button issue. A competent cell repair shop should be able to replace it.

Yes, that's true, I've found a lot of people over the Internet with the same problem.
By the way, I could finally solve my problem; after searching for a while, I found a YouTube video that showed a peculiar way of solving it... And it actually worked!
Well, it looks like I cannot put the link because I'm under 10 posts :cyclops:

Thanks for your replies!

Are you referring to banging the power button? It wouldn't work for my friend's power button. He had to have it replaced because it failed a multimeter test, apparently.

Yep, exactly!
Like the video said, I bumped my phone a little bit because the power button was kinda stuck inside the phone, and that really worked...
I was amazed! And I'm so happy it worked! No need of having it replaced. [emoji16]
