Nexus7 is turning itself off during overnight charge

I was wondering if anyone else was having this issue.
I've charged my Nexus7 overnight on three occasions. Plugging it in before I went to bed (~1AMish) and getting it on my way to work (~8:30AMish). Out of those three times, on two of them, when I went to get my tablet the unit was powered off. I know for a fact that when I plugged it in, it was on, and no one touched it in the meantime.
The most recent occasion was this morning.
On all three occasions, the unit still had 40-50% battery life left.
On two other occasions, I've charged it during the day for a few hours, and it was fine.
Additionally, I've never had the unit turn itself off overnight when it wasn't plugged in. And I'm using the charger/cable that came with it.
Lastly, the first occasion was on the stock kernel/rom, and the second was on the motley kernel (but stock ROM).
So it seems like something is causing the unit to power itself off if it's on the charger for too long. This is concerning, because the only thing I can think of is that it's overheating and shutting down as a protection mechanism.
Any thoughts or ideas?

Plugged mine in for the first time last night at 11:30. Slept till 8, hit the power button and everything was fine.
Basically, no issues here.

Was it fully charged when you switched it back on? I ask because I shut mine down for the overnight charge last night (plugged into a laptop, not the wall - there's only one socket near the bed and my battery-sucking phone gets that juice), and when I woke up it had only gone from ~30% battery to 55%.

I had this happen to me on the first unit I had... I was actually using stickmount to transfer some data and left the usb adapter plugged in for about an hour and when I picked it back up it was DEAD.... I could not get it to boot up at all until I did the recovery (power/volume) method and then everything was fine but I returned it anyways cause of a defective screen... I am now on my 3rd unit from Sam's Club and I think I might have a keeper...? (Knock on wood) :fingers-crossed:

Yes, it was at 100%.
Keep in mind that charging via computer's USB port takes much longer. Maybe your laptop went into sleep mode and shut down power to the USB port?

Nope, my fiance's phone was plugged into the same laptop and it was fully charged in the morning. And as a general rule, I've never known the computer to automatically sleep while on AC power, even when the screen is closed.

Thank god i'm not the only one experiencing this. My nexus 7 always seems to turn off after I leave it overnight plugged in for charging. I thought it was a kernel issue but i've switched kernels and i still experience it. Still unsure as to what is causing it.

Same here. Its odd it only seems to be for an extended period of time. Also my battery was indeed fully charged. Should I exchange at Sam's?

There is nothing else wrong with the tablet. I have a feeling it could be some sort of hardcoded feature where if it notices that you're plugged into the wall charger with 100% battery and the tablet is in deep sleep for a certain period of time, it automatically shuts down.

Ikr. First time it happened to me I was like wtf? It might to stop the 2 amp charger from overcharging? My unit is fine, I think the sound is just right. I might get that squaretrade warranty though.

Well, I feel a little better that I'm not the only one with this "problem".
The question is, is this a "problem" or a "feature". I guess we won't know unless we ask Google/Asus (good luck getting that answer) or enough people respond saying that it happens to them too. But if people start saying it does not happen to them, it makes it more likely to be a problem....

This happens to my phone due to overheating. The tablet does run hot when charging. See if there's a temperature logging app and run it overnight.

It would be nice if it would just cut off the battery charge and run directly on A/C. But I guess I would rather have it power off than explode.

isnt bad to charge it overnight like i believe from 1% to 100% chrge is like almost 3hrs fully chrged.. i just alarm myself for 3hrs to check if its fully chrged already then unplug it

True, it's not good to constantly charge the battery once it's full.
Most devices however have a built in charger kill switch once it reaches that point. Laptops for example will switch to A/C power and only start recharging the battery once the level drops to ~95%. I believe my phone does this as well (SGS2).
I guess I'm OK with it turning itself off, assuming that it really is a safety feature. My main concern was something was wrong. It would have been nice if they mentioned this in the 100pg Nexus Guide eBook though .

I want to add my own observation -- mine was almost fully charged, I plugged it to my computer's USB, turned the screen off, walked away. A couple hours later, the Nexus 7 was turned off. But I was shocked to find that, pressing the power button couldn't turn it on. The first thought came into my mind was that my computer did not charge the Nexus 7 and the battery ended up completely drained. So, I plugged it to the wall charger, left it on for a day. 1 day later, I tried to turn it on again. No, it didn't work. I was panic and decided to Google about how to reset and checked if I could wipe it and sent it back for a replacement. I found that pressing the power, vol up/down button at the same time can force a reboot. I tried that and bingo, it booted into the bootloader. Before I wiped, I decided to try to boot back to the Android OS. Surprisingly, that worked. I was happy and decided to ignore this incident. Then, today, it happened again. This time, I immediately used the power + vol up/down trick to reboot, and that booted me right back into Jelly Bean. I checked the battery status and it's fully charged, which meant my computer was charging it all along. For some reasons, the Nexus 7 would just turn off itself. And, in my case, pressing the power button alone would not reboot it.

Sounds like to me that it's hard locking, not "powering off", and you're forcing a reboot. Long-press of the Power button should do the same thing.

I can't say I have much to offer in regards to this issue, but am I correct with my observation that everybody experiencing this issue has experienced it while their N7 was plugged into a computer of some sort for an extended period of time? Has anybody had this happen when plugged straight into the wall outlet?

Here's another update with an interesting 'twist' since my last post.
I've charged it twice in the meantime. Once was, again, overnight, and I woke up to find it powered off. A simple "on" press brought it back on.
However, on Saturday, I used it heavily and was down to about 40%, so I plugged it in around 11AM. I meant to grab it around 3PM when I went out, but forgot about it. Got home late, and went to look at it at about 11PM (12 hours later). It was charged to 100%, running off the A/C power, and still on.
This is weird, because if I leave it plugged in "overnight" for 8 hours, it will almost always turn off sometime before I grab it. But when left plugged in during the day for 12 hours, it stayed on. I wonder if it handled the situation different based on the time of the day???

[Q] Is my Nexus 7 dead? Please give me options to charge/turn on

Good evening everyone, I have a Nexus 7 8gb, but the thing is, I cannot turn it on now.
It happened as follows:
I was using it every now and then, mostly to read and play.
I was using the charger to charge my cellphone too (XTC Explorer) as it was a lot faster, being 2amp/h.
I updated the cell to 4.1 and at the same week noted the battery wasn't running that long, but blamed it to the rom.
The cellphone also took a lot longer to charge with the nexus charger, yet again I blamed the rom.
I noticed the Nex was at 8% while reading so decided to charge it, but I guess I forgotten.
The next time I wanted to use it it wouldn't turn on. I figure it had no battery.
I plugged the nexus charger to the nexus a whole night and in the morning it still wouldn't turn on.
I figured something must be wrong with the charger, so I tried with the cellphone and nook color charger, but both are .5 amps/hour.
It wouldn't charge, neither connected to the pc (also .5a/h via usb) so I tried a psp go charger, as it is rated at 1.5 amp/hour, much closer.
I connected it at night and saw the charging icon (white on black battery with the ray) and left it overnight.
The next morning it wouldn't turn on either.
I've bought it almost two months ago and I really enjoy it =) but now I'm desperate.
I cannot call google play for the warrant because I'm in Argentina, and I don't believe they will ship me a replacement, nor anything. This one my brother bought from them, but he went back to US a few days ago, and I didn't think of giving it to him to RMA.
I tried keeping the on button, for 5 secs, 30 sec, 90 secs, 120 secs, and no dice. Also tried holding the Up Volume key to restart it, but no chance.
Please help!

Had a similar issue to this over the weekend after not charging for 2 days and the battery going dead. I let it sit on the original charger overnight and for some reason it did not charge. It kept booting and shutting down once it booted due to a low battery warning. It eventually got to the point where the screen would go to fuzzy lines and light but no boot.
To finally get it working I did a combination of a few things but don't actually know what got it going.
Put it on a different (kindle) charger and let it sit for an hour or 2, did several hard resets holding both just the power and also the up/down volume and power all at the same time for up to 60 plus seconds. I switched back to the stock charger and did an additional hard boot by holding just the power for 30+ seconds and it started booting and charging.
I did however put it on the charge again last night and noticed this morning it was still at half battery and didn't get a charge. I ended up putting it on a mifi charger this morning and it's charging again so don't know what is up with the stock charger. Also, have all the latest updates to 4.2 as far as I know as there have been charging issues reported with earlier versions...

Try this, it just saved my device:

try holding down the volume DOWN and the power key for 10 seconds, then release the power key and keep the volume down key pressed, and it will force the unit to restart into the bootloader from any stage, its effectively like pushing the restart button on the front of a computer and constantly pressing the delete key to get into the bios.

[Q] can't charge or turn on my nook hd+ at all

My nook was idle for a day or two, as I remember I hv shut it off.
But then yesterday I try to charged it, the light was green then turn to red, n then it went off, usually the nook would turn on right after I plug the charger. So I didn't notice it until today, and I tried to turn it on by pressing the power button, and the N button together as well, both didn't work.
It seems that I can't charge it or turn it on. Everytime I tried to re-plug it to power or press power button while its connected, the light went on in green to red then off again.

Connect your charger. Let it stay on charger 20 min. Then try push n button. If this not bring screen on then try push power button for 5 sec. Again if not then try power and n button combination.
Hope this helps.

Thx! Turns out tht external charger didn't work.

I think that last opinion is make CWM sd card (without CM10) and insert it do device, then try to switch the device on (with charger trick or power button). If you then get it live all is ok. If not then last change is wait when battery goes empty and charger wakes it up.
Actually i predict that item is itself faulty and you must return it for change (maybe not faulty at hardware side, only OMAP inside code got corrupt).

I don't know, that might because I rooted my device, and I did sth wrong. Sometimes it would reboot itself, since my cmw card was inserted, it would load tht root page so I found out. But I live in Asia so returning the device might be too costly, probably won't do it.

It could be several things. The most likely is it was trying to update itself and could not because the CWM card was there. I don't think your device is defective.

Now i can say same. With first information things was other.

...It's more or less a known bug to those of us who use CM10 (even to some who use stock), the battery simply often can't tell how much she has left. So she may fluctuate from 1% to 26% to 0% a moment later . In one such moment my Nook HD+ shut down (went from 26% to 0%). So I put it up for charging thinking (naively) that it would boot up ... it didn't, now all I get is a charging icon that never goes away (orange led remains lit). What's more I *know* it has some charge (the "26%" was the right value) and I know the battery works, so what prevents it from starting is the "battery charge sensor".
It's a pretty silly way to lose your (my) tablet over. Even more so given how much I grew attached to it for my workflow. So what's next? Is there a secret way to convince it to boot. As I said both the hardware and its software is in top condition. I guess an alternative would be to ship it back for replacement but I'm afraid that I've lost my receipt and -as I said- it's a silly way to lose your tablet over, there *has* to be a (fast) way out...
BTW when connected to my PC my device manager briefly shows an "Omap 4470" unknown device (with an exlamation mark) which goes away few secs later, so I cannot attain ADB control over my devices either (sadly)....

If you are running CM10 or 10.1, there is an easy way to connect with ADB. Do it wirelesly over wifi. That is built into CM. Just enable it in the developer options. No need to mess with the USB cable and windows drivers. You can do the same thing with rooted stock by installing an app called ADBWireless.

At the time that could not happen , since (as I had implied) my nook was not booting to begin with...
Anyhow, what I did was to leave it for three solid hours on the charger, and after that period of time it booted on its own wiithout warning. It's the first that such behavior was/is ever present to my nook and it's deeply worrying. A battery fix for the CM kernel couldn't come any sooner; now, if only verygreen was around

There's a few ideas on a couple of other threads including putting it in the fridge, etc. Question, if you plug it in, does the charging light come on? Does it come on after pushing the power button or the N button? If so, take your SD out, leave it charging overnight and try again. It often reboots when in this state and if there's an update problem, that could be the issue. Also, it is sometimes erratic on when and how it charges, be careful with the connections.

As I said it came up on its own, without warning after leaving it for 3 hours on the charger...
As for your question, the led (charging light) was on all the time but it would only show me that it had no battery (couldn't charge even though it was ... charging?)
Maybe the fridge makes sense in those situations, as it was indeed into a (relatively) hot environment and maybe it couldn't charge as a safety against overheating and since (at the same time) it also thought it had 0 battery. But what I can't understand is why needed 3 hours before starting to charge up, it was already cool enough long before ... strange things are/were happening with my battery all along and I worry...

Yep, I've noticed the same thing a few times. It no longer panicks me. When it doesn't turn on, I take out the SD, plug it in, wiggle the connector a few times, and let it alone. So far, it has always eventually rebooted, often as you say on its own. Quirky, but not fatal at least. One poor guy on here never did get his to turn on, but the key was the charging light,his didn't come on.

Need help cannot turn on Nook HD+ at all
Hi!
I cannot turn it on at all and it won't reboot.
It went out some point I didn't watch it. When I connected it to the charger the LED next to the connector starts blinking amber and green for a few seconds and then stays blinking red and makes a high pitched noise.
The only reaction I get is when I press power on an volume down after some time - it display turns on an shows a charging sign - but it never really seems to fully charge. I left it on the charger over night - still the same. Once the display blinked and showed “nook” but went out immediately after a few milliseconds.
Might it be some kind of bootloop!?!?
What combination to press to make a reset?
Thanks in advance for any help

Kindle Fire HD 7 Shuts Down Randomly

Bought a Kindle Fire HD 7 (first gen) back about 2 years ago. Has worked fine until a few months ago when my wife noticed it would randomly shut off. Battery could be 60,70,80 or even higher % charged. Once it would shutoff it would rarely boot up unless plugged into a charger for a while. Has anyone else had this issue?
I should mention it did this with untouched Kindle OS and also has done it with CM11.
Im wondering if this is just a hardware issue or if this is something that can be resolved via software/troubleshooting. There isnt anything important on the tablet so i can wipe/install as needed.
Any help would be great. Thanks

I'm thinking after two years your battery may be at the end of it's rope. You might try replacing it.

Thanks for the input. So last night i charged it to 100% and used a battery calibration app. Took it off the charger and started running stuff to keep the screen on and use the battery. Got to about 70% and it randomly shutoff. Tried booting into TWRP and was in for about a min before another shutdown. Was unable to start it up, would get to the CM load animation then it would die.
Then i did something either stupid or genius. I hit it a couple times and shook it. While doing this i tried turning it on and it booted. However after a few mins of use it wold shutdown. Did this a couple times where it would only turn on if i was shaking or "flexing" it. So this led me to believe this must be a hardware issue.
I decided to open up the back and make sure nothing seemed loose. Pulled the back off, unscrewed the battery and pulled out one end but not all the way out. Pulled some various connecting cables including wifi cable and plugged them back in. I booted with the back off sitting flat on a table and it ran without issue playing back a movie for at least 30 mins. I then put the back o and pulled up google maps and had that on/screen on for at least another 30 mins, occasionally pivoting and zooming in and out. That got me to about 45-50% battery.
I plugged it in to charge over night and will see if it now will behave. Im hoping it was just something loose. Will report back, Thanks

My best friend is having this same issue, and I was hoping if your findings have been positive. If so, we may do like you did and hopefully solve the issue.

Run a Nook HD+ without a battery.

I bought my Nook HD+ in 2013 and it has been a great companion all along. About two years ago, I noticed that the battery was not what it used to be, requiring charging too often. Last year, I installed LineageOS on the Nook.
About three months ago, something happened to the battery so that the Nook would turn on and be usable only if the main power was connected. If I switched off the charger, the Nook would immediately shut down - and by shut down I mean it would just blink off, not shut down over a few seconds. Also, in the shut off mode, it would lose battery a lot, like 20 to 30 percent in a day, without any usage.
Then, about a month back, I forgot to charge it for three straight days and now it won't turn on at all. When I connect the charger, the charging light turns from green to red, and stays there, indicating the battery is charging, and the back of the Nook also becomes hot, but whatever I do, it doesn't turn on. When I press the power button, the screen comes on and shows the charging icon for a second or two and then goes off. I've left it charging for a couple of hours, maybe six or eight or so, but it still won't turn on.
If I remove the battery and turn on the main power, the charging light keeps blinking green and red over and over. So, is there any way to use the Nook without the battery, running it off the mains power only? And if there isn't, is there any way to turn it back on? I've already gone through the threads here and tried some of the things but nothing has worked. I don't have a higher power wall charger, and it is not possible to go out in the present condition, what with the lockdown and all.
Please help.

Hi
I also have a Nook HD+ that I'm still playing with

I also installed lineage on mine a year or two back, but I've had random issues with mine. I'm going to try to reset and reinstall it in the near future (like, maybe this weekend or next).

I know that, if the tablet runs dead, you _have_ to put it on the original Nook wall charger and let it sit overnight... mine just went dead a couple of days ago and I tried just plugging the cable into a generic USB charger, but it didn't charge. I then remembered this and plugged it into the Nook charger and it charged overnight.
If I remove the battery and turn on the main power, the charging light keeps blinking green and red over and over. So, is there any way to use the Nook without the battery, running it off the mains power only? And if there isn't, is there any way to turn it back on?

I have no idea about this part... I've never taken mine apart (I wanted to buy a replacement battery a few years ago but they ran out and I never found more). Update: I just searched and there are a few battery replacements listed with Google search, I just don't want to pay 40.00 to 50.00 when I can buy a new tablet for a little more than that.
I usually just leave mine plugged into my bedside clock and it keeps charged, or if I unplug it plug it back in within a couple of hours.
Hope you find an answer.

better off buying a new tab
