Won't turn on D:

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.

[Q] Help, Blank Screen, Backlight on, no picture

Pretty self explanatory. It was dead for a couple of days, I put it on the charger for almost the whole day, now I get no picture, but the backlight is on when I hold the power down a minute. I bought it at walmart, doubt I have the receipt, and didn't get any extended warranty. Is there a way to fix this issue?

I've got the same issue. I was playing Tupsu, when suddenly my n7 rebooted and there was no picture, just semi-strong backlight. When the tablet died, the battery was about 45-50% and I was charging it through notebook's usb port (original n7 cable). I tried to turn it off, but pressing and holding the power button only made it reboot once again (i assume it was rebooting, since the backlight was turning off and on in a second). I've tried it many times, with tablet plugged into wall/usb charger, and even with the power+volume up/down combination, it would still behave the same way. However sometimes after rebooting there was not only backlight, but also thin, mostly white, horizontal lines, appearing in random places of the screen (appearing and disappearing after like 50-100 ms). It would stop only after a reboot, and happened every 5-10 reboots.
I've decided to let the battery die to see if it changes something, and as you may guess - it didn't. It died estimately after 2 or 3 hours. Now it's all the same, except for when I plug it to the charger, there's only a very low backlight (still no picture) and it's blinking... It also makes this continuous "electricity-related" (sorry, I don't know what's the word to call it ) sound. After I press the power on, or let it charge for 1-2 minutes it boots up, and there's just a semi-strong backlight, like earlier.
It's a refurbished 8gb n7, which I got 5 days ago from the polish Asus online store. Oh, and the speakers weren't 100% fine, if it changes something. They were fine at first, but after i plugged headphones in and out, they were making cracking sounds when the volume was over 50% or something like that. Is there any hope I can fix it myself?
edit: the android ver. is 4.2.2, not rooted
the device is getting warm on the left side when being charged, or just turned on...

Have you tried pulling the battery for a couple of minutes?

Nope, i don't want to mess with the hardware since i've bought it only few days ago... I'm afraid it may leave some traces of being opened, i'm not willing to take the risk.

You won't leave a trace pulling the battery. Just use a guitar pick or credit card and run it round, the back comes off very easily.

Yeah that is definitely worth a shot. Just pull the battery.

Ok, I did it.
Didn't change a thing >:[
btw. I didn't actually pulled off the battery, i've just disconnected it - it doesn't make a difference, does it? and another thing - the backlight was turning on immediately after connecting the battery... with these randomly popping horizontal lines.

I've got this too!

I've got this too! Pulling the battery does nothing. Last time it just fixed itself, now nothing.
Worried I'll have to take mine back.

How did that 'fixing itself' happened to you if i may ask? And how long did it last?

Your tablet has gone into sleep mode to protect the battery from further damage due to its low level of charge. What you're seeing is by design, as complete discharge of a lithium based battery is bad for it. You should never, ever, let it sit dead for a couple days. If you do discharge it to the point of shutdown again, immediately put some sort of charge on it, as waiting to long will cause the battery's protection circuit to fail completely. Best practice is to not let your device go to the point of shutdown, but rather to plug it in when not in use. Your battery will have a longer lifespan.
Plug your N7 into the charger and immediately press power and volume down to get into the bootloader. Once there, use the volume key to scroll to Power Off Device and then press the power button. After it powers off, unplug it and then plug it back in. It should then charge normally.

You seem not to have read my posts at all. When it happened, the battery was about 45-50% and it was plugged into the laptop's usb port. It suddenly rebooted and there was no more picture, just the backlight - and it lasted for like 2-3 hours (maybe even longer)! Can a completely discharged battery power the backlight for this long? After it turned off at last, i put it on charge and i've tried the power+volume method and it didn't do anything (btw. i already wrote about it)... then i let it charge for like 5-6 hours and it didn't change anything except for the fact, that the battery was evidently charged, because the backlight again lasted for few hours.

Actually, I was addressing the OP without realizing that this was a zombie thread.
To answer your question though... yes, when in sleep mode the battery can still turn on the backlight and keep it powered for some time due to the low power requirement of a black screen. Many users that have found themselves in sleep mode actually have their tablets enter into a prolonged cycle of bootloops. From the sounds of it, your device seems to have, for reasons unknown, put itself to sleep.
Anyway, I digress... I know you've stated you've tried various combinations of the power and volume keys. Have you attempted holding all three buttons for approximately 30-40 seconds while the tablet is plugged in? If it that will force it into the bootloader, you can follow the steps that I posted to get it up and running again. If not, then it seems your best available option is to seek an RMA from ASUS. Given your speaker issue, I'd send it back regardless- you shouldn't be expected to deal with battery and speaker issues after only five days.

Nexus 4 Died?

So i was playing a game called The room battery was at 1% but was connected to a charger and it suddenly powered off and a red light started to blink then the light disappeared and now it is connected to the charger and has no response, is my phone dead? :S i'm so nervous.

The device may not respond until it is fully charged. I think it's best if you wait until it's charged fully and see what goes from there.

Maybe it's the adapter that's broken? Try changing adapter/cable or try charging using your PC

So many threads on this. Charge your phone overnight. Not working? Rip off the back cover and disconnect and reconnect it. That's a no go? Check another thread.... Wish you luck

When I have get the red light I have to keep trying to power it on taking the charger in and out. Last time took 30 mins for it to go away of continuously trying to power on and taking charger in and out. The reason I do this is because if you leave it on charge with the red light on the phone will not charge. You can leave it over night and the red light will still be there and your phone won't be charged! It will only charge if you get the charger screen up and the red light is off.
Happens to me if don't have much battery and I try to watch something on the TV with slimport connected

plug it in, and press and hold volume up plus power for 60 seconds, then release. It should then power up automatically or press the power button again. This key combination is the equivalent of a battery pull, which is what you have to do when it gets locked up like that or battery drains too low.

none of those worked i tried it's bricked i guess

Your phone's fine. The reason it powered down even though it was plugged in is because it was at 1%, and considering you were playing a game your phone was probably expending power faster than it could charge.
When there's absolutely no power left it won't respond no matter how long you hold down the power button. Just plug it in & let it charge for a few hours don't worry.

It's not bricked, there are a lot of threads about it around here. You have to charge the battery, and keep trying with vol down + power, until it takes you to recovery. From there choose reboot.

you have to disconnect the battery and charge it withe external charger for an hour then reconnect your battery . i hope this help you .

My observation leads me to believe that this is typical for a battery that has been left on with a completely discharged battery. But it shouldn't take an hour.
My thinking is that this is product of bigger batteries and higher current requirements. Although I'd like to hear from someone if holding down the power button will start the device in spite of very low charge.

The Bootlaoder ( power on+vol down) not working.
When suddenly at least may 45 min, the battery icon is appeared and the device is started to charging.
Then It's on and full working.
Really strange.

[Q] Phone not charging

Last night I let my phone fully discharge by accident. Now it won't charge when plugged to the turbo charger. It just gets warm and thats all. Is this a known issue? Also I tried the Vol - + Pwr Buttons for about 5 minutos with the turbo charger and it doesn't turn on.

It could take quite a while for the phone to turn on when it's completely discharged. Might need 20 min+ charge for it to even turn on. If that doesn't work, try holding down the power button for a very long time (15+ seconds) after having it hooked up for maybe half an hour first.
