Hey, this morning, I looked at my G1 and checked email. I pressed the off button briefly as I always do and put it in its case.
5 mins later I went to get it and it was off? I had to hold the power button down and it came and and went through the full startup sequence!?
I used it a little and then left it, 10 mins later or so I came to use it and same thing!?
Battery was full as it had been on charge over night.
It's been fine since, any ideas.
thanks

I've gotten a few sudden quits and restarts/poweroffs myself randomly out of the blue. Seems like some leftover bugs in the system software, not a hardware issue.
So today I left my tablet to charge, it was at like 25% left, while I went to out to my practice. When I returned about 2 hours later, it wouldn't turn on. Before I had left, it was charging so it's not that it ran out of power because the outlet didn't work. I switched the outlets, plugged it into a computer, pressed the power button a bunch of times; nothing. Perhaps I got a defected unit or downloaded a bad app? I don't know :/; ideas?

try holding down the power button for 15 seconds
Hold the power button 15 seconds, let go, then try again for another 7 seconds.
Wow, that actually worked, thank you so much (held it till it turned on, about 10-15 seconds). Would you happen to know why it had just turned off like that? I'm at 81% battery now, so it turned off at some point on its own, and why did I have to do such a long power button press?

i believe there is a sleep mode/lock hiccup sometimes. I experience it with my media dock but not my keyboard dock. its weird and sometimes annoying but not too much to kill my day lol
Yeah this happened to me too. Just a small quirk.
Oh, ok, thanks guys lol I had like freaked out.
I got my Tab yesterday. Used it then set it charging overnight. Won't power on this morning. The back does get warm though. I tried holding down the power button for at least a minute and also tried the 15 then 7 approach. Nothing.
I also tried an idea from a different forum (referencing a Froyo glitch) and tried touching the screen while holding the power button.
Does this sound like a hardware fail?
I had the same problem. Held the power button for 15 seconds and then 7 and nothing happened. Held the power button for a long time. What do I do next?
Mine didnt turn on today. Tried the 15 second press procedure and nothing happened. I grabbed my wall charger and plugged it in and left it sitting there for a minute. I tried the 15 second procedure again and this time the screen lit up and was showing that the battery was charging because it was in red. After about a minute the tab booted itself and all is normal now. I guess my battery went dead since i hadnt charged it and completley turned off my tab. Thats why it rebooted itself. Nothing to worry about.
happened to me too
looks like there is a glitch ... mine was left charging today ... and it did charge but did not want to start... i did leave it on.
I connected to PC and press Power ON + Volume Up + VOlume down all at the same time and it did seem to restart ... worried there is something wrong with it though.
I bought it in USA and Im in UK I wonder if things go wrong if Samsung UK would repair it.
I've had it for about 9 days and have used it every single day. Last night I downloaded 2 movies onto it and everything was fine. Today it would not power on one bit! I charged it over night so the battery shouldn't have drained. I ended up fixing my problem by doing the following:
Held the power button.
At the same time, placed a finger on the screen.
Held it down for 15 seconds or more and it booted up!
Not sure why it only worked when I put my finger on the screen.
I ended up exchanging it either way just in case.

For some reason this keeps happening to me when I leave it to charge over night.

Every night?? I charge it every night and it only happened once. Hopefully my new one is fine.

this also happened to me for the first time this morning from leaving it on charge overnight.
however i was able to start it by removing cable and holding power for 15secs.
what could be causing this? I hope it doesn't happen every night.
I had this problem as well a few weeks ago. Samsung sent me a shipping label and told me to ship it back. I got it back in just under 10 days. They never did tell me what was wrong but they shipped back my original Tab.
Guys,
Is this happening when you leave it booted up and charging overnight or is the unit powered off and charging?
I will say that this issue has only happened to me one time and it happened under the following conditions (Ive had a Tab sense launch day):
- Battery was at 35%.
- While booted, I plugged it in to charge overnight.
- The next day at 09:00 I attempted to use it and had to hold the power button for 15 sec to get it to boot.
So, It *might* only happen if its booted with low battery and you charge it overnight. Powering it off and charging doesnt appear to cause it at all in my case.
Yes it happened while powered on and left to charge overnight. Battery was probably around 30-40% as you said.
Still doesn't explain why it would happen regardless of the % of battery left. Hence the reason it's meant to be charging.
I've had it happen very quickly. High level of charge, plug it in, walk off, come back, unplug, and it's dead, need the 15 second press to power back on.
Not a huge deal, but annoying. And a bit scary, since mine went into the "sleep of death" once already, took four days for the battery to drain enough to break the nvflash loop it was in.
hi all, today when my nexus 7 left around 15% battery, it showed the warning sign to ask me charge it, so i thought of finish download 1 small apps before charging it. just before i hit the install button, the screen suddenly turn off and whole device was power off.
i tried to on it back (press for 30sec) but no use. so i go and charge it, after trying many times, i finally managed to on it back, but just after few minutes, the screen appear many lines ( just like those old tvs) and it turn off again...then, i tried many times only i managed to on it back.
after that, i continue to leave it there to charge. but after almost 4 hrs( and still counting), the battery only 45%.
wat had happen to my nexus 7? previously i had no such issues, and normally i can fully charge it within 3 hrs. i just got it for 1 week, can anyone tell me what happened? will it damaged my device?
thanks.
no people facing same issue as me?
hey there, im facing the exact same issue and symptoms as you!
the sudden off, the old screen tv effect and shuts down again.
a battery logo appeared though and im leaving it to charge now. strangely it was showing 18%
im running cm10, what about you?
I've had the same issue for first 2 times I charged the Nexus, then it went away. Seems to be battery related, faulty battery?
Same thing happens to me as well. Happened on stock 4.1.2 and happens on stock 4.2 as well. I never try to let it reach below 20%, just to be on the safe side.
Me too!

It happens to me too
Not sure if it's battery related but it happened twice and this is what my battery graph looks like.
Anybody with more info?
I am also on CM10 using setCPU app to control CPU speed when the power is low.
There is one other thread talking about this:
http://forum.xda-developers.com/showthread.php?p=34878700#post34878700
I placed my info there too.
Edit: It's actually happened the last 3 days now ... I'm going to exchange it today.
I get a message "shutting down, low battery" I used to get message telling me to connect to charger. Before I could finish what I was doing now I have no choice. Seems to happen after update 4.3
fix
somehow the battery calibration is out. only fox is to leave it charging for about 20 mins before trying to turn it on. as by then only will the 'x' logo appear. OR if you cant wait popout the back cover, remove/unplug the battery it works. another longer fix is to. turn in back on after it is able to, go to battery settings refresh it, plgg and unplug your charger. the shutdown logo should appear again and when you look to the top, the battery % will revert to its correct amount of 0% try to do this as soon as it is able to be turned on.
Hi guys,
My Nexus 7 (2012) turned off(not properly) when the battery level was low and won't power on. I tried a battery from a working tablet and tested my battery in another tablet. It seems like the issue is somewhere else.
These are the things I tried:
- leave it for a couple of hours charging (no battery sign at all)
- hold the power button with/without the volume levels while it being both connected and disconnected.
- tested my battery in another tabled and put a fully charged battery from another tablet
- made sure that the battery is connected
There was one more thing I tried - to press the Power button with no battery inside but the tablet being connected to a laptop via the USB cable. One could hear something like a boot noise coming from the tablet (doesn't happen when the battery is inside)
In December, 2015 I installed a Custom ROM with android 5.1.1 which I found here http://forum.xda-developers.com/nexus-7/development/android-6-aosp-grouper-t3268172/ (the thread was renamed and is now about the Android 6 update) The tablet worked fine for these 3 months but one day when I was checking my email it went off and won't respond to any actions.
Could you please help me to fix it? I'm just not ready to give up on this tablet. Thanks!
Both you and i, same model, essentially, the same circumstances. I also tried every method you mentioned as well. Even down to the flashing of a rom. Same results. I even tried "jump starting" the battery. Not wanting to give up on it. It sits in my closet like that boy in A.I at the bottom of the ocean, waiting... I know that is not the reply or help you were looking for. Just so you know, you are not alone..

Well, that's a good start, at least I am not the only one!
Have you tried to connect your device via USB? My laptop can see a connected device but it can't recognize it and I hear some sounds coming from the tablet when I try to hold the `power` button. This made me think that it can be a display/screen related, so the device works but we can't see it due to the broken screen/display. Don't know how to check that though.
Same here, stock Nexus 7, won't turn on, just switched off one day and won't come back on, have tried everything as suggested above, can't get it to flicker, doesn't even register the power connection with a green light or anything

Try replacing the screen, just to check. If that doesn't fix it, at least you have a brand new screen!

I fix mine,
let it sit on the charger for a hour, then hold down the button for 20 sec
same issue here as well ive had it for about a year and im not able to access anything via my pc google help forums had no answer either, looks like we may be screwed..........
Hi, I just had same issue with my tablet only thing is that I was using it with ~20% of battery, nothing special - browsing the web using chrome, then the screen lit gray and shut off. After that no response either from charger, holding power button for 60+ seconds didn't work either, tried re-connecting the battery, still with no signs.
And then, I tried to plug in the charger and then pressing VolumeDown+Power immediately after connecting the charger. Suddenly got some response, that battery charging icon appeared, and it shows my battery charging, but from 0%. Still waiting to charge a bit until I can try to boot it.
I'll update this post with any news.
EDIT: When I connected my tablet to the charger it had that hissing sound, but after few minutes it stopped.
After 15 minutes of charging I managed to boot my Nexus7 with 7% of charge in it a that moment, It seems to work for now.
Summarry of what I did to solve my problem:
1. Opened the back of the N7 (I used a guitar pick for this) and re-connect the battery.
2. Then plugged in the charger and at the same time pressed VolumeDown+Power, battery icon lit up but went out, repeated step 1, and then step 2 again gave me animated battery charging animation which showed up for like 10 seconds
3. Waited for 10-15 minutes and tried to boot normally. And it works now

Honestly, I do not think it is the battery, I can see the Charge signal, and the Battery is showing 1,784 VDC tested unplugged and disconnected, my smart young co-worker seems to think POST is failing, I still never see a "Charging" indication.
Does anyone know , Is there a fail safe, say the battery is disconnected, and usb charger is plugged in, will i just see all 5VDC at the sub port, ?
I never see a screen flicker, DEAD battery sign, nothing.
co-worker, tried some things that made sense when he explained what he did, I would have to agree with him.
Now it is rooted, 4.x something I forget, Never went to 5.x did once early and did not like it, Back stock, ran 2 days no issues, Rooted again, 4.x still do not remember, worked great 3-4 months, Sons ran it to DEaD and that was it, put it up for 90 days or so, wife got new tablet, kids have Fire each, and here i am tabletless, CRAP, did not want to throw to much $$$$ at this thing, nor did I want to buy a new one.
Samsung Tablet here we come.
any body want this Nexus 7, it is a 2012 model.

I would be more than happy to take it off of your hands mate. Probably gonna use it for parts to keep mine running.
I had my tablet on my bed, turned off, with ~60% of battery this morning.
On the afternoon I wanted to use it but it wouldn't turn on.
I already plugged it to the charger, nothing.
Tried pressing power + volume up + volume down (several seconds), nothing.
Same thing with only the power button, nothing.
When I keep the power button pressed while the charger is plugged in, the icon if the battery with a thunderbolt inside appears for a second, then disappears.
If I don't let go of the power button, this icon keeps appearing for a second and then disappears (and appears and disappears in a loop) and nothing else happens.
Any ideas?
I don't want to throw this tablet away.

I just had this happen to me a little while ago. My tablet turned off with the battery not even close to empty and couldn't get it to turn back on. I could get into recovery but not the OS. I tried flashing different things but it kept having issues. I tried leaving it in recovery mode to drain the battery all the way. Then plugged in the charger while it was off and let it charge up again. I flashed a rom again and I got it to turn back on. Everything seems to be back to normal now. But I really don't know what exactly fixed it or what caused it. I was flashing some older ROMs on it when it happened because I wanted to go back to Marshmallow. So, sorry I don't have a real answer but those are some things that I tried. It could be early signs of a bad battery but I don't know for sure

Well I could't enter recovery ao I just let it drain its battery, after some days I plugged the charger, the battery started charging and it booted.
So... I have no idea what it was, but now it's working again.
Yes, I'm guessing the batttery is dying so I'm starting to look for alternatives.
I guess I'll just go for an iPad, dont know what other tablet could be a good replacement for this one.

I agree. There's not really any other Android tablet that I think is a good replacement though. I like the size of the Nexus 10 and wouldn't want anything smaller. I thought about the Nexus 9 but even that has issues with running the latest version of Android. I guess tablets are just going out of style.
