Broken Power Button

My power button has been acting funky lately, i thought it was just a software issue until i switched my battery today and realized it was hardware. now i cant turn on the phone.
Is there anyway to power on the phone via fastboot or some usb command? i need to get some files off the device before the device swap but i dont know how to turn it on without the power button =[
any ideas?

One of the bloggers on Droiddog.com had the EXACT same question. Yes it's possible... read her method here:
http://www.droiddog.com/android-blog/2010/06/nexus-one-power-button-failure/
Basically:
Plug the phone in– USB or AC works fine.
Wait until the charging light comes on.
Remove the battery, while leaving the phone plugged in.
Replace the battery.
After about 3-4 times, the phone should boot.

i need to know if i can turn it on via usb command, ive already called in for the device swap.

if you take it out and wait till right after the charging light goes off then put it back in it seems to start up a couple seconds later!

Glad you got it up and running. Sorry I misunderstood the question.

mytouch 4g Totally dead?

While in the middle of reading an email (using the gmail app) and downloading an update to a marketplace app (Go SMS Pro), my phone suddenly froze and a minute later, shut off and hasnt come back on again. I switched batteries, tried different chargers, nothing works. no screen glow, no charging orange light (battery was at about 80% when it died), nothing. the water damage indicator is white.
Plugged it into my PC and it recognized a USB device but could recognize what type etc and asked for drivers.
The phone had original software (2.3.4) and wasnt rooted or anything. Just a month out of the warranty period. Tmo threw their hands up and offered me their off contract pricing for new phones . is it time to start looking for a replacement? Any hope?

that is the weirdest thing ive ever heard. can you get into the bootloader? (vol down + power)

the phone behaves like there is no battery in there. And I've swapped out the battery (wife has same phone), and even my battery works in her phone.

but can you get into the bootloader? its not completely dead since your computer detects something when its plugged in so it could just be a messed up rom that kicked you into a different mode..
if you can still get into the bootloader you should technically be able to reinstall the stock image or even root and flash a recovery tool

You can make sure the connectors are clean for the phone, or it may be your power button, I have seen many people talking about dying out power buttons, there is a fix, I think I will have to look it up, it was on these forms.

Read up again, plugging it in and holding down either the home or the trackpad button for 20 seconds could work. Also found this post below.
jjbadd385:
If your power button is broken, you can seperate the black rubber from the chrome bezel, right at the power button, you will see a silver dot with a silver ring around it,,which is the flex ribbon, and very, very small. Anyway, take a piece of aluminum foil and twist it up, now touch the silver dot and ring simultaneously, for like 1 or 2 seconds, and it will come on, if your flex ribbon is not broken. I have an extra. Mt4g with a broken power button, and I power it on this way a few times a day...takes about 10 seconds.

Here is a good thread if it is your power button.

Sorry if none of this works :/

I've seen this happen already with a different phone, I went as far as sending it out to be repaired and the service department said the processor shorted out and needed to either buy new or a refurbished one. It will still show on a computer because there is power to it but due to the processor going bad it won't do anything from that point. I would go with the mt4g slide it has great reviews and a solid forum here.

[Q] Nexus 10 wont turn on.

I placed my nexus 10 on charging yesterday, and after a while (2-4 hours later) when i came back, i found the device to be turned off, I tried the power button in all the combination with volume buttons, but still no luck (even held the power button for 3mins) I searched online, and couldnt find any help on other forums. Some said to keep it on charging overnight and then try powering it up. But still no luck.
I dont get any notification when i connect it to charger, although when i press the power button while connected the screen lights up, and battery charging sign shows up.
Any help would be greatly appreciated.

So you cannot even get to the recovery?
You ether over charged it (very unlikely to happen) or you have a faulty N10.

No, can't even get to recovery. But i have been using the device for over two months now, nothing like this ever happened. What about the charging sign when i press the power button. It might be some kind of a sleep mode or something, no?

Could be a bootloader corruption, software issue, hardware issue or some part of the hardware "thinks" that it is still on when it is not causing it to not switch on.
Have you noticed any issues before it just came off like extreme overheating?

Well, yes the tablet was getting overheated after a long session of hd videos, or games, but that use to happen all the times.

I believe this is normally called a "Sleep of Death" or sometimes "screen off death". Hold power + vol up + vol down at the same time for 5 seconds and you should boot into fastboot. From there hit the power button to turn the tablet on. Then go about finding a better ROM/kernel combo that doesnt give you this problem.

You just need to press power and volume down to enter the bootloader.

Are you using the charger/cable that came with your device?

Its working.
Weird how it was taking any input from the power button though. I kept the tablet on charging over night and i tried turning it on in the morning and it worked.
Thank you all.

I've had my Nexus 10 for less than a week, and this morning I encountered this problem. I was working on setting up syncing through an app called FolderSync and SugarSync. Syncing of one of the folders seemed to go into a loop. The device locked up completely a couple times. I got the process running again and left it running while I went for a workout. When I came back no way could I get it turned on.
I had tried all the things suggested here before checking here for help. I'll try your "solution" of leaving the device on charge overnight. If I can't get it going tomorrow morning I'll return it to Staples, where I bought it.
I have an iPad and have never encountered anything even close to these problems. Bought the Nexus 10 specifically to run the Vim Touch app for Android. The only Vim app for the iPad is horribly crippled.
Sounds like this thread pretty much exhausted the possibilities by the time epicbearman discovered his "solution," but if by chance anyone has any further suggestions I would be grateful.
Thanks,
Eric Weir

I had the exact problem as the OP and none of my chargers worked. I then googled and found someone that said to try to charge via their PC USB instead of the wall charger. I left it plugged into the USB for a couple of hours and the charge went to 4% ( so it must have been very dead ) and all is well.

I charged it via the usb charger, and connected it to my pc overnight. Try doing that.

Take off the back and disconnect the battery and reconnect it

Thanks. If I'd gotten this in time, I suspect it would've worked. But when I couldn't get it started after trying everything else and leaving it on charge overnight, I returned it to Staples.
Will order a Nexus 7 from Google. If I can get Vim Touch running successfully---my reason for wanting an Android tablet---and I find the screen to small for heavy writing---I want to get by with a soft keyboard---I'll order another 10 and give the 7 to my daughter.
Thanks again,

Nexus 7 won't turn on

It seems there are already several threads about this seemingly common issue with this tablet, but I've tried the normal checks and still can't get any life out of my dad's nexus 7 whatsoever.
I've found several threads stating it's just a loose battery, but in this case it isn't. I've checked absolutely every single connection I can get to without removing the void if removed bits, and can't find anything suspect. However it still won't turn on, won't charge, etc. It's not a faulty charger or cable either, we've all got android in my immediate family and we can't get any life out of it with any lead or charger. It was simply working one day, it was turned off the way it always is once my dad had finished using it, and now it simply won't come back on again.
I also saw some people say to get it into bootloader mode by holding volume down and power straight after plugging it in, but that too does nothing whatsoever?
Does anyone know of anything else I can try, short of sending it back to Asus?

How long have you had it?
This sounds like something that should be addressed as a warranty situation, as anything else may be kludgy at best, and may fail again just after your warranty runs out.
I wouldn't really waste any more time.
JMnsHO.... :beer:

My dad has had it about half a year, maybe a little more. But he bought it from Comet, who no longer exist since they went under just after Christmas, so he can't return it to them now. Unless it'd just go straight to Asus instead.

I had exactly the same issue.......I fixed it by disconnecting the battery and reconnecting which by the sound of your post you have already tried.......you should be able to go straight to Asus for repair.......good luck....
Sent from my Evo 3D GSM using xda app-developers app

After probably 30 days it would need to go back to ASUS anyway.
As I'd said, I wouldn't waste more time fussing with it.
They'll take care of it and still preserve the balance of the warranty.
If you messed with it too much, you may find yourself with none at all, and on the hook for the cost of the repair.
Make the call.. :thumbup:

Well I've not done anything that shows I've been in there like I say, so any manufacturer warranty should still be intact. Same goes for the software too, not rooted, on the standard rom and kernel, etc.
I was just hoping I could fix it for my dad without having to send it off.

Not yet, but anything else would be more 'intrusive'.
How long have you been working on it?

Not long, only 10 minutes here or there to see if I could find something loose. I might check the voltage of it's battery to see if it's flat, and also check to see if any power is getting to the battery while charging. That'll help prove if the battery or it's control board is dead or not.

Just checked the battery over. It's a 3.7v battery according to the label, and my multimeter shows 3.7v, so the battery is fine with no loose connections. At the connector for the power button ribbon cable, I get the 1.8v that should trigger the tablet to power up when the power button is pressed, and the power button is good too, only showing continuity when pressed. Again, no loose connections. But the bloody thing still won't turn on.
Any more ideas?

When you say that you "tried all the normal checks", does that include all of the fixes listed in the sticky dedicated to this subject?

Yes, your thread is about a faulty or loose battery. As I've said, it's not a loose connection and I've now tested the battery too. Unless you can think of something that I've missed?

That sticky has all of the well-researched methods of addressing the collection of related issues (won't turn on/won't turn off/battery status). It is not only about a faulty or loose battery - there's much more.
Give it a read and let me know if there's a fix in there for you.

I have read it all, and unfortunately there's nothing in it for me.

If your able to get to bootloader maybe try to power off then let it charge for awhile then boot, or hold the power button for a good min

It won't turn on at all, so it can't get into the bootloader. Tried already.

I know you tried almost everything in the box, but when you plug it in the wall and press and hold the power button do you see the screen light up but still black?
If yes ( hopefully ) then continue holding power button then press VOL down til arrow pointing with START appears. Cycle through with VOL down til you see power off and select.
After it shuts down unplug from wall and replug and let it sit for a long awhile
If this didn't help at all sorry......good luck....warranty?

Nothing happens whatsoever mate, even while plugged into the charger. Tried the original charger, my s4 charger, my old HTC chargers, from the pc via USB, etc. None of them make any difference.
Got a feeling it might be the motherboard, as it has power. Can't be the display since I've tried getting a logcat from it after holding the power button for a while to make sure it would have turned on. ADB just kept saying "waiting for device" as if it wasn't plugged in, confirming it isn't even turning on.

Can anyone think of anything I've missed?

Did you take the phone in for service? What did they do to fix it, if they fixed it... I have a dead phone and need some answers if they are out there. I'm looking through every post that has anything to do with this subject and coming up blank - just like my phone's screen!
Part of my issue is that I had a shut down from out of nowhere on NYE. I was able to bring it back up with the power, volume up, and Bixby combo the next day. Foolishly I assumed it was a fluke and went right back to using my phone just as I had before. I saw an article about disabling the Bixby button, which seemed to be the thing to do... When the phone shut down the next day again, I couldn't bring it back because I no longer have a Bixby button for the combo. It's been down since Jan. 2, and I'm at my wit's end. Can you please update your phone status? I'd appreciate it if you can!

Lol disabling the bixby button in software does not mean you can't trigger download mode. That level of software has no idea what packages you disabled ?

Did you have Substratum themes applied before updating?

Happened with me last night, bunch of updates and then black. I was gonna send to warranty, then someone told me Power + Bixby + Vl down and it worked. How can I find out what did it

When I called Samsung, they were clueless how to get it started again as we walked through all the button combinations they had. It was fully charged when it stopped working, both times. The second time it took me a few days of trying on my own, calling, Samsung and then going into their repair store.
They took it back to work on it after I explained what was going on. He tried several things and came out and told me it may need a replacement but wanted to try one more thing. Hours later, he came back and said he hooked it up to a charger and it had been dead. Once it started charging, it showed the green battery, lightning bolt and blinking circle. It still didn't start normally, but the three button combo worked at around 20%. I'm not sure if he tried before that, but it came back on.
I've discovered that my handset is extremely sensitive to cold temperatures and shuts down. I'm in the Midwest and have been working outside in a tent like structure. I listen to music, books, or podcasts while I'm working. Many times, I will put my phone on a shelf while charging but still listening. The phone shuts off and first I have to wait for it to warm up, then it has to drain the fully charged battery, and then I start charging it again. After the first time on my own, I did the button combo right after it started taking a charge and it worked.
I'm not sure if a replacement phone is the way to go, because if this is common on the S8, I might end up with another dud that would just frustrate me more. I like the phone, but this quirk is annoying.

Last night my phone was charging and accessible fine. This morning I have a green light at the top showing I assume that it's charged but the screen is totaly black. nothing I do brings up any screen. I tried all the button combos I tried plugging it in to the charger and nothing shows any kind of reaction. I tried plugging it into my computer and the computer said it was setting up device QUSB_BULK. Then said it was set up but even after it supposedly complete I could not find the device. What the hell?

S8 Black Screen
Is the green light staying on? This happened to me on one of the many shut down times I experienced. I think I narrowed it down to my phone not liking cold temperatures, but I don't know if that is your phone's issue. It hasn't happened since last winter, so I haven't needed to do any of this for quite some time, but I'm trying to remember all of the steps I took.
I'm gonna suggest getting the battery drained back down to zero. In order to drain the battery when it's black screened, I kept trying all the button combos repeatedly for, it seems like, maybe three or more days... I couldn't tell if it was dead on several of the occasions, but when I had an indication light, it went off after days of doing any and all button combos, just to drain what battery I could.
Once you do that, while keeping it out of any extreme temps, (if there have been any) then plug in the adapter that came with it, using a good quality USB-C cord and charge it again and see if the charging screen comes up. (The Fast Adapter Charger that connects with USB 3.o is the best to use. Samsung wanted me to use the original cord, but I have no idea where that is! I just used a good quality cord.)
If that doesn't do the trick, then it's not the same issue I had, and I wish you luck on finding out and getting it fixed! Don't forget to update the site for others to find out if your tricks work... (You can still try this, but it may be just to rule it out as a possibility.) Try draining it more than you first did, and then plug it in again to see if it takes a change.
If it is taking a charge again after draining and plugging in your power cord, wait until you get back up to at least 20% and then try the three button start (Bixby / Power / Volume Up at the same time) and make sure you hold them for up to 30 seconds or until it kicks on. One time, I think I held it for almost a full minute. But it did take the change, restarted on the three button combo restart, and didn't have any new issues from its down time.
If this works for you, come back and tell us! If not, come back and report what you try and what the results are.
I really hope that helps! Good luck!

Sounds like a system problem, you can try to use the button to force a reboot, if there is no response, you can try to reinstall the system, if this still can not be solved, then you may need to replace the new screen, you can go to Witrigs to see Note 8 screen, they There is an original Note 8 Super AMoled screen for sale. The price is also relatively low.
