Press & Hold for 15 seconds to power up? - Nexus 7 Q&A, Help & Troubleshooting

My wife's N7 sometimes starts normally, but very often you have to press and hold the power button for at least 15 seconds before you get the boot screen google logo.
I have searched but not found a thread dealing with this issue. I do not have the powering off/battery status issues, the tablet ALWAYS boots up, just that it seems very odd you have to press and hold the power button for so long sometimes. EDIT... HERE is a similar thread.
Any ideas if there is some fix for this?
The tablet is on Kitkat OTA update.

Your device is not shutting down properly. For me if i load a bad kernel or do some thing nasty in kernel settings then device some times goes into sleep of death. It is on but not responsive. You are just pressing power button for 15 sec to reboot it. Plz update your kernel if u have custom kernel or check settings if u have changed any. And if u haven't done any thing then start paying attention to apps after which these problems start to happen.
Factory reset would also fix the issue.
P.s: do not undervolt if you are and if custom kernel then try increasing lowest cpu state frequency to 200+. Just a thought. Not every device can handle all kernels.

Hi
Thanks, I had thought that not shutting down properly is the cause, but now I have updated to stock kitkat, wouldnt that have come with stock kernel? Yet the issue persists...

Some app is causing sleep of death or ur tablet is faulty. Please do a through checkup and try to find out what situation is likely the be the reason to cause the problem.

I wonder if there is an app for tracking/logging that...
I am not going to uninstall every app just to find this out.
Perhaps someone else with the problem has already found out some apps that cause this, anyone?

Mark.

well i have the same problem myself, even if i shutdown the device normal.
Sometimes i need to press the power button a few times for like a few seconds. Even after a factory reset.

Ok, thanks BL4CK...
So that seems to point at HARDWARE being the problem... since after Factory Reset it cannot be software, and since I have STOCK kernel STOCK firmware, it cant be the ROM...
ah well... just have to live with it, it seems... though it does behave as though it is not shutting down properly.
cheers
Mark.

Same here...device is untouched, no root, no custom rom etc.
At first after unboxing i thought the nexus was doa, untill i realised that you have to keep pushing power button for 13 seconds!
What i hate even more: it's still on 4.3 because OTA updated doesn't work!
-update notification appears
-downloading update
-confirming "restart and install update"
-nexus turns off
I would really really appriciate some help!
PS: i do NOT want to update via usb to computer connection

Here is a thread with some good fixes for the hard start problem (hardware problem):
http://forum.xda-developers.com/showthread.php?t=2090826
If an app was causing SOD when shutting down, a factory reset would resolve it.
Should also check bootloader to be v4.23
Start the device by pressing n holding PWR + VOL DWN until you enter the bootloader.
The info should be somewhere along the left-bottom side of the screen.
Once u get the version number, use vol up/down buttons to navigate until u reach power off.
Press power button to confirm power off.
Start normally/whichever way currently works for u.
Used to have this hard start problem alongside touchscreen problems.
Under the nexus's back cover are actually some antenna pins along with some grounding pins.
Sometimes these pins corrode or have poor contact, then it causes some electrical abnormalities.
Try to clean these pins with an cotton earbud and some metal cleaning solution. Stuff like carb sprays for example. Nothing oil based. Wet the bud a little with your solution and clean gently. Then use a dry bud and gently wipe dry the pins and all residues. Repeat a few times if needed.
Also try to push the pins outward so it will have more contact with the back cover.
!!Be very gentle and use minimal pressure, these pins break easily and if they do you will need a new board.
Other than that, check the battery connector too. Unplug and replug. Or other suggestions/solution in the thread above.
Good luck!

Word of advice be extra careful when messing with bootloader. I have seen many loss their devices because of simple yet stupid mistake.
Please ignore my spelling mistakes, English is not my native language and i hate on screen touch keyboards.

someone save my phone..plzzzzzz it won't turn on

so like...my phone cant turn on at all..no lights..no response..it's like practically dead..im sure the battery is fully charged...but the phone isn't working at all..i don't know what to do..i did everything possible to reset it and everything..i've done everything i can to it..and kept myself from throwing it across my room..so...anyone have any idea of what happened to my phone?..or what i can do to fix it..?
/cry
What operating system (WM/Android/WP7)/bootloader (magldr/clk) do you have insralled?
Did it work before and suddenly now it won't, or did it never boot up since you got it?
Did you do something like trying to flash a rom, install HSPL or an android bootloader, or is the phone stock WM?
Does it vibrate or anything when you try to boot up, or just no response at all?
Check your battery pins where the phone connects to the battery, maybe one of them is bent and not contacting the battery properly.

uhm...what..? *cough*..it's..a windows phone..i bought it when it first came out..and it works ok..for awhile i suppose...erm..im not a techie geek...so..you lost you after the first question...and it doesn't vibrate or anything anymore..it's as if..it's like a stone..no lights or anything..if i plug it in onto my computer it makes funny noises..and it's like the computer doesnt know i have it plugged in..and if i unplug it..it makes that weird noise computers make when you unplug something...so..i get like no responses from it..nothing..no lights..no sound..nothing (the battery was at 95% charged before it stopped working)
it all happened when...
my phone kept freezing on me every time i get a text (not a text friendly phone is it?)..and i would always just carefully take out the battery n reset my phone..only this time..in the process of it..it just wont reset or turn on anymore.. =[...ooh and there's no physical damage to the phone..all perfectly in mint condition complete with phone covers..screen protectors..and the sticky plastic stuff it came with...
Were you pulling battery to reset phone rather than use reset button next to battery ?
If you have been pulling battery in & out rather a lot checking battery pins as mentioned above would be a good idea.
In the hands of a non "techie geek" these devices are nothing but a problem ...
sms issue sounds like you needed a better ROM installed or perhaps mainboard fault that has esculated !

erm...yea...i did pull the battery in and out a lot...but it was never really a problem..and the pins n stuff are fine..>_< really flexible though..uhm..i also press the reset button a lot...i just thought the phone was soo pretty..cuz of the huge screen..and the awesome camera..i didn't know it would cause me so much trouble..could it be..'cause..i bought the first few phones of it when it first came out..?..i never done anything else to it..too bad tmobile said phone isnt under warranty so i cant replace it..cant afford a new phone..or pay for repairs..so i thought.maybe some techie geek or something could tell me what to do..
could be faulty hardware as reasonbly common but most of your running issues such as freezing on sms sounds like newer or custom ROM flash was needed.
Be 100% sure all flexible pins seem to protrude enough & spaced correctly to contact battery terminals & all are clean.
Couple of questions & things to try>
when plugged to charger does red LED show ?
Does it go to bootloader when you;
While phone is Off - Hold Volume down & press power button (keeping volume down pressed all the time) use reset button to exit bootloader screen
Have you tried hard reseting it !
While phone is on:
Hold Volume up + Volume down & press Reset button
While phone is Off
Hold Volume up + Volume down & press power button

Nexus S power button conspiracy theory/oddity

My power button has been malfunctioning for about 2 months now. That isn't to say it is 100% dead, but at times it'll work if I smack the button about a few times, and sometimes it will be completely unresponsive. I have read up on the subject and found a thread with a response from a guy claiming to be an engineer who said the micro switches they use in these phones are somewhat weak and only work for a limited number of presses. Recently, I changed roms, and to my surprise the power button worked great for a short period of time. Since then, I've found that when my power button starts acting up, wiping the dalvik cache put it back to normal. This lead me to thinking, and I've come to believe it could very well be a hardware problem that is meant to happen. I am by no means a coder/programmer but I have studied it enough to know that certain code can be written for a device that sets a "timer" for a piece of hardware to die out or malfunction. If that's the case with this, then it makes sense somewhat that wiping the dalvik cache resets this timer for a short time. Anyone have any thoughts? Am I crazy tinfoil hat wearer or does this make some sense?

I AGREE! I thought it broke a while ago but I did a complete wipe and put a brand new rom on it. Heck I almost sent it to Sammy but for some reason it stared working. I dont think its the dalvik cache though. I have a feeling its ClockworkMod Recovery because sometimes it says a key was disabled and I had problems after that. I couldnt lock my phone.

well, you solved your own theory in your statement. since when does smacking your phone equate to a software issue? my power button went in august, mostly. it started showing the behavior that you described about 4-6 weeks beforehand. i say mostly, because the physical button doesnt work anymore(rarely a response from it). but ive figured out how to work it to my advantage/needs. i can wake my phone by shaking it now, and put the screen to sleep. also can be done with a light smack in the right place on the back of the phone. but to be practicle, i remapped my search button to use as a power button and wake my phone with the volume button. really, the only hard part is navigating in the bootloader menu since the volume buttons wont work there with the power button broken. so ive learned to work it by lightly, very lightly, tapping on a certain place on the back of the phone near the power button. this "loosens" the volume buttons and lets me navigate the menu. then i tap the phone again to make a selection. this in no way indicates a software issue/conspiracy to me. when it just started displaying this behavior, i thought it might be a software issue too. but it turned out to be all physical damage.
You know, the funny thing about when it stops working is that it's never all at once.
It's a degrading process of malfunction until it takes repeated button pressing, not so much force, to work. After that it works so seldom that I'm forced to do something about it. It's for those reasons I think it's something more than a hardware problem.
From your experiences, even after a full wipe/new rom installation, your power button still doesn't work, if only for a brief time?
P.S. The new touch based recovery from team win works really well for those of us who can't use our power buttons

Hmm my guess is that there are multiple issues that result in a malfunctioning power button. Props to remapping your search button to lock your phone. It would be a great work around if my phone ever had this problem again. Have search to lock the phone and volume keys to wake it. I'm unsure how you remapped your search button though. Maybe you can tell me how?

Agreed! If you have no access to a computer with adb/fastboot control the touch ClockWorkMod recovery would be very useful.

ive been using twrp recovery for a while. even the non touch version has a no power button option. but i dont believe that theres anything else but hardware issues here. it is a degradation. at first it comes and goes, later it mostly just comes( ) and doesnt go. i can even hear a slight rattle in the power button area now if i shake the phone.
about after flashing.. at first, 50% of the time it would work after flashing, but it was just coincidence. but now no. btw, i flash many times a day, even then when it first started acting funny. flashing, wiping, it just doesnt make a difference, its coincidence.

ButtonRemapper app, available here on xda for free http://forum.xda-developers.com/showpost.php?p=9399440&postcount=1
you want v0241. i have all the power button functionality with my search key except waking the device(volume rocker wakes my device). short press screen off, long press power menu, long press plus volume down for screenshots.
@tw1tchy, I totally agree it is multiple factors, which is why I can only speak for myself based on my experiences, although your overall experience seems to be similar to mine.
@simms22, I have never noticed a rattle in my phone, its likely that you and I have different causes attributed to the power button failure.
Not trying to beat a dead horse but just for the sake of being thorough, have you tried ODIN? I noticed a substantial difference when I ODIN'ed back to stock.

I really like my Nexus S, but I kinda hope this power button self destruct kicks in soon. I see it as a feature - to make buying a Galaxy Nexus easier to justify. Good looking out Sammy.
I've had a similar problem for the last 4 months or so. It started when I dropped my nexus without the cover onto concrete floor. Not good I know.
But anyway...ever since then the power button been funny. Sometimes it didn't work at all and I couldn't turn the screen off and on. It was really bad. It took a while but now I kind of know how to handle it. Still annoying mind u.
Basically with mine the trick is to press the button really really hard towards the top end and it works fine. I've also noticed what some others are saying about changing rooms and doing resets etc. It seems to help as well.
But yeah...I still love my nexus. Lol. I think by me dropping it is the reason for my problems. It probably landed badly and loosened some part of the connection in that section or something. But as I said...all Is good now that I know the trick to it.

I've had my NS since Christmas Eve 2009 and the power button completely stopped working 2 days ago. I did notice over the past few weeks that it wasn't responding properly. TBH, my NS has been through a LOT in the past 14-months (multiple impacts, spillages, kids etc), I'm surprised it's lasted this long
I'm now using the ButtonRemapper app to use 'search' as the power button. Works great! Plus my volume keys wake the phone up so all is ok.
I love my NS and wish I bought another one when CPW had them for £150 sim free!
It might be time for me to let go of the NS , just have to decide which phone is next (but thats for another thread lol)
ugh mine is under a year old. im very angry that this happened so quickly. im gonna try giving samsung a call. hopefully the will replace it. i shouldn't have to hack my phone in order to make it usable.
@rener78 You seem to have a vast misunderstanding of how sarcasm works. Just as future reference, posting dry, tasteless irony up on the internet as a smart-mouthed statement of ill will is about as practical as a chocolate teapot.
@staplebox Lol! Well played, sir or madam. I can't say posting a thread containing the words conspiracy theory doesn't grant me at least a well placed snarky comment. Although to be fair, I was kinda bored when I wrote it.
@ALL Yes, I get it, we've all dropped our phones before. I guess I expected a bit more from Sammy since my little old HTC hero that I beat halfway to hell is still going strong, while I pampered this nexus and its already giving me problems >1 year in but that's a whole different discussion I suppose.

great mine just went out yesterday... had mine for a ltl over a year now.
No tapping certain areas or anything works.
I did notice it slowly degrade over the past few weeks.
I used the fix my power button app so my volume keys wake up my phone, but sometimes after using that 5 or 6 times it will stop working too so i have to plug my phone in the charger to turn it on. Is there another way of getting the volume keys to act as a wake button??
edit: i'm gonna try out that button remapper i saw in an earlier post.

if you are using an ics rom go to the main settings, security, lockscreen.. now disable the lockscreen. you can now wake your device with the volume button. its a feature built into ics.
interesting did not know this. Thanks, I think I'm still gonna use the button remapper to change the function of the search key to the power so I can reboot and stuff and go into recovery and such easier since i'm running cm9.

Here's another question what if i need to pull the battery?? I'm rooted and running CM9 what if i go into a boot loop and i need to pull the battery with no charger around (i know how to do it with a charger) would the button remap solve this?

no. the button remapper app doesnt do anything when off or the screens off. honestly, i no boot many times a week(because i test the trinity kernel as its being developed before release), ive figured out a system of light taps near the power button to let the volume buttons let me scroll, and to select in the bootloader.so for me its a non issue. to power up from being powered up, i dont do anything. a, pluging in powers it. b, tapping the back powers it when no usb is available. c, it powers up by itself usually, seconds to a few minutes after powering off.
Being a heavy user of my nexus s since July 2011, the power button died last Sunday.
One of the most important problems i had after that was that i was unable to lock bootloader before giving the mobile to samsung service, because the stuck power button caused problems to fastboot commands and the bootloater usage(menu) in general.
Finally i decided to go to the service and give the phone. The result was that in about an hour they replaced the button and gave me back the mobile. The repair was covered by the 2 years warranty and the unlocked bootloader did not cause any problem to that.
Up to now i have a "brand new" nexus s and i hope that the new button will last much longer.

Power button not working after upgrade to 9.2.1.17 / US

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..
http://forum.xda-developers.com/showthread.php?t=1546640
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:
http://www.techrepublic.com/photos/cracking-open-the-asus-eee-pad-transformer-tf101/6270147
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:
http://forum.xda-developers.com/showthread.php?t=1391254
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?

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 ?

Power button not working

Hi guys.
My Galaxy Note 3 power button has just completely stopped working. Is there a setting that turns off the power button functionality that I might have accidentally pressed?
Cheers.
Edit: I should elaborate here. The phone is switched on, everything works as normal but no matter how many times I try it, the power button just not do anything (holding it down, pressing different areas)

Did you try a battery reset? With the phone off, can you get into either Download or Recovery mode? That would eliminate the possibility of an OS issue.

I kind of scared to turn the thing off in case I can't switch it back on. I'll try it though.
Edit: It's dead. Taken the battery but can't switch back on now. What a joke.
Bad luck brian i feel sorry for you

I know I kind of expect this bad luck these days after having two faulty Nexus 7's. My Galaxy S2 power button is still going strong after 2 and a half years but the Note 3 lasts 7 hours

It's a dud mate. Faulty unit.
Just send it back and get it replaced.
Just send it for replacement. There's a reason phones come with a warranty that covers manufacturer defects. Whining about it to strangers in the forum is not going to fix it for you.

I was posting to see if any one else had the same problem or if it was a setting I'd missed. Arsehole.
Cheers everyone else I'll replace it tomorrow.
This is exactly the sort of thing that makes me worry about voiding my warranty. Decisions, decisions....

Yeah this is definitely the least friendly of all the Android forums. Sorry to hear you have a dud unit mate. Get it replaced.
My power button is not working to turn the screen off. Long press works to bring up the power down menu or to do a hard shut down. It works to turn back on though. Seems to happen after I plug it into the wall charger. Restoring a nandroid backup fixes the issue.
Not sure if it's related but my PC's USB crashed after trying to plug the phone in and use USB 3.0 to transfer files. I had to refresh my W8 PC to get the USB working again.
I have the Sprint version, rooted and running JellyBomb.

I have the same problem. my power button is done for. whenever i need to start it. I plug it in and go into recovery and reboot from there. I also use this https://play.google.com/store/apps/details?id=com.plexnor.gravityscreenoffpro&hl=en for screen timeout and lock. And you can also get exposed and gravity box and there is a status bar tweak to double tap the status bar to lock screen (put phone to sleep).
I tried everything then found the solution on another website
My note 3 has been with me for almost 2 years now and it's power button stopped working about 2-3 months ago. Until now I avoided draining the battery below 2% and was fine but just today I dropped my phone and it shut down. I knew that my power button didn't work because of hardware problems so a soft reset didn't work for me. What I found however is that if your power button is dead you can just very quickly remove and re-insert your battery and your samsung device (I have no idea if this works on other brands) automatically boots itself. I'll give the link too incase I wasn't clear enough and I hope this helps people who shared my worries.

Keeps resetting..help please..

Greetings fellow geeks.
i have a problem with this i9500..
it was working fine, suddenly it resets.
it keeps resetting every 4 seconds.
won't let me go to recovery.
i can go to download mode. but it won't respond to volume button, and resets after 4 seconds.
i have a custom ram on it.
if i place a battery back in, it will power on and keeps resetting every 4 second.
what should i do?
Maybe your power button stuck in? But if you can enter download mode then not I guess. You can always flash original firmware if you haven't necessary data on it.

Ok sorry my friend, read that you can use download mode well. I think there is something with your power button. Did you drop your phone? It shouldn't reset every time in every state, that looks like hardware failure. You can easly open your phone with little screwdrivers, but you will lose your warranty. If your power button is broken you can always order new ones from China, I did it with $1,3 (power and volume).

100% your power button is stuck. Try to wiggle it lose or replace it.

TNX mate.
if i may say something, the button isn't stuck.. it's pretty clicky and sounds like working fine. is it possible the cause is coming from something else?

No it's your power button for sure.
I had that issue with my S3 LTE. It is indeed the power button since it does exactly the same that my did, try to use some alcohol in a swab and pass on the button (let it penetrate the button area, next click several times to try to clean the button from inside).
Good luck.

I have the same problem with my i9505, I always fix it like this:
1) remove the battery
2) let the phone rest w/o the battery for min. 10min
3) put the battery in and try to go in recovery
4) if you can wipe cache and try to turn it on
If the problem happens again:
1) remove battery
2) short the pins like this x/-/x/- , then x/x/-/- and then -/-/x/x (x is the connected pin) with something that conducts electricity like a metalic ring or high resistor or s/t
3) do step 3) from the previous one
(Anyways what you do is that you drain the capacitors in the phone, and on the power button, that capacitor is the main problem)
If that doesn't help, then try to leave it w/o the battery overnight
EDIT: well that is not a permanent fix, the fix is probably that you need a new power button, or in the worst case a new phone
