Hey everyone,
I've tried searching, but no luck, so here's my issue.
My nexus 7 was around 25% battery last night so I plugged it in for the night.
Woke up this morning and the backlight was on, but the screen was off.
When I unplugged my n7 the backlight turned off. Hitting the power button had no effect.
I then tried pushing and holding the power button for roughly a minute, nothing.
I have disconnected the battery and still no response from the unit.
I plugged it back in for roughly a minute as well, still nothing.
Unfortunately I don't have access to a charger right now.
Is it possible the battery is dead even though it was on the charger all night?

Weird.
Just plugged it in to my car charger and it booted up. Battery is completely dead, so I guess with the backlight staying on all night it didn't charge.
Now why would the backlight stay on if the screen is off...

Don't go flashing different roms and kernels now like most of the idiots here, it could just have been your charger being faulty or a bad connection to the tablet overnight. if the problem happens again then you can investigate further.
BTW, were you charging from your PC/Laptop with a USB cable or through a wall adapter? i've had issues in the past charging my Nexus 4 and 7 not charging overnight on my PC
I feel like a broken record but since I've fixed a ton of n7s with loose battery connections, I would recommend checking the internal battery lead to make sure its not loose. Asus didn't do a good job of making sure all n7 batteries were secure and this allowed the battery to shift and pull the power lead out. Some clear scotch tape on the connector and one on the battery (avoid the copper tape areas) will eliminate this problem if that's what you have.

I ran into this problem. Initially, my Nexus 7 didn't start. When I plug in the charger the screen would flicker from time to time but there's no indication of charging. So I decided to open it up to see that the battery cable has loosened. So I managed to fix it and use it happily thinking that it won't happen again.
Since last week, the same issue happened. I thought it was the same issue and opened it up to see that the battery cable is firmly in place. So I got a shock. I removed it and re-inserted it again to see if it fixed it. But nope, it won't turn on. And now it's been a week and I don't know what to do It's nothing wrong with the loose cable cuz now it's firmly in place.
Now when I plug it in to charge, the screen will just flicker (as in the back light will turn on and off in 5 sec intervals). What do you think I should do? I tried holding the power button for 30 secs as well.
I bought this new from eBay and still under warranty. But I live in Sri Lanka. So when I bought it, I had to ship to a friend in the US and had to wait till he came down. So it's not easy for me to ship back and to receive another device. Hopefully I can find a solution to fix this myself.

Make sure that the cables between the battery and the connector are intact and not broken. One or two people reported a broken cable.
Does it boot while plugged in to the charger with the battery disconnected ? You could simply have a bad battery.

I checked again. The cables aren't broken. They are all in good shape.
It doesn't boot when I plug in. Actually it doesn't show anything on the screen. If I look closely I can see static flicker on the screen from time to time. Just like the static in TV but much much less. Like only a few of those in certain places.
When this happened the first time I opened it up to see the loose cable. So fixing that helped it then. But now I dunno what's causing it.

Might have to try a different charger, maybe something stronger. I JUST had that problem with my GF Nexus 7. It wouldn't boot with her normal charger and the screen would flicker like a TV. I used my Nexus 4 charger and it worked.
She had left the battery fully drain for over two weeks and I think the battery didn't appreciate it.

Yesterday I updated my ROM using the goo.im manager. It seemed like everything was working fine, though this morning I tried to wake the tablet and it did nothing.
I can't get into recovery or the bootloader or anything. The screen is consistently black. I've tried holding down the power button, holding down the power button with volume buttons, pressing various buttons in rapid succession, but to no avail.
Any ideas for what I can do to fix this?
Thanks.
Could it have somehow discharged overnight? Plug it in and let it charge a little and see if it comes on?

It's been plugged in for a while now, and it's still not turning on.
In a dark room plug it in to the charger, see if the screen shows static, if so your battery may be unplugged.
Just did a write up on it

Just tried this and didn't get anything. I don't think that's likely anyways, since I haven't opened up the tablet or messed around with the battery.
How long are you holding power button?

When you plugged the charger in did the screen show static? If so when you removed the cover did you make sure it was plugged in, or just look at it? The reason I ask is the plug will look plugged in, but the plug will not be fully seated.
And as nespid stated how long did you hold the buttons? It can take 30 seconds or so before it performs a hard reset or enters recovery.

I sometimes wonder about the craftsmanship of the power button. From day one, bone stock,I sometimes have to sit and fuss with the power button if its powered off.

I had exactly the same issue. Black screen, nothing from the power button. So I took the back off ( which comes off really easy.....just used my nails!) And pulled out the power to the battery reinserted, put the back on powered up and all was ok...........strange one....but it got mine up and running.

This, sometimes my N7 takes about 10 seconds to turn on, other times I'm pressing it for a minute or so.

More likely this is related to the sleep of death, where when you shut off your N7 it does not power down correctly and requires a hard reset by holding the power button down for 20-30 seconds.

This is what I would be trying at this point. And again, it can look like the plug is securely fastened when it's not if you have the battery that does not take up then entire space as shown in the pictures I posted.
Alright, so I opened up the cover and unplugged the battery and plugged it back in. Still not working :/

Odd, these are hard to brick. you would essentially have to start by wiping recovery/bootloader. It sounds like the battery is completely dead. what happens when you plug it in? I assume you see no indication of it charging? Again, in a dim/dark room can you see what looks like static when you plug it in?
Okay. So this happened to me a few months ago. It died from me not charging it for a few days ( love the battery life) so I plugged it in before I went to sleep. When I wore up and tried to turn it on, I was having the same issue. It would not boot or anything. It was dead as a doorknob and I thought. "No way....I bricked a device in my sleep....(next flashaholics anonymous meeting on Wednesday)"
So I thought maybe the charger broke and it didn't charge. Well I tried different chargers and outlets and everything. Nothing worked.
Then I plugged it into my computer to see if I could get the wugfresh toolkit to connect. (It didn't) but after like an hour messing with wugfresh while my nexus was plugged in I went to try to boot to fast boot (for the 100th time) and it worked (that or it showed the charging symbol by itself) either way the screen only remained on for a few seconds. After trying this again an hour later. Watching it closely, as soon as the screen turned on I ran it to my Asus charger and plugged it in.. Then it charged normally and was fine.
Tl;Dr
These batteries should never reach 0% mine probably became z little too close to 0% took a lot of time and methods to make the battery take the charge.
Moral: don't let the nexus 7 reach 0%

If it doesn't turn on and...
You reconnected your battery (dismounting the back),
You pushed the button for 5 minutes! or more (i tried all of em, all possible combinations)
You plugged/unplugged it from your PC then tried to turn it on
...and nothing happened.... Plug it to your PC, go to device manager and if it is recognized as APX
Welcome to the "BRICK CLUB"
Your only hope is to get in the bootloader
pd. Theres no nvflash... search your warranty (got mine second hand :crying

Yep mine did the same thing, my battery connecter was visibly wonky though, only slightly.
It does seem to me to be a small design problem that the battery can move a little and pull on the connecter, either the wire needs a bit more slack or the battery needs securing. I used some tape to hold it and hopefully this won't happen again.

This may be the noobiest of questions, but is there anything special that needs to be done to chage the unit or is anyone aware of units with bad charging ports. I just unboxed my Nexus last night and as my usual new device ritual put it on the charger for a few minutes. Noticed the battery icon came on for about 5-10 seconds and then disappeared. Figured it was normal but when I powered it on we only at 43%. Shut it off and let it "charge" overnight but when I powered it back up still at 43%. Tried a different cable with same results. Calling store today but wondering if I might have missed something.

A common problem seems to be that the battery connector is not properly seated during assembly. Pop off the back cover and visually inspect the connector. Also, there are a handful of threads regarding the issue you're having. You may want to search for them and check them out for some pertinent info.

Thanks. Does the back just pop off? Was running out the door to work so didn't get to search. Will check when I get home.

Ok, so got the back popped off and all look connected. Power the unit back on and somehow it's at 49% and my wife said when she picked it up earlier today it was at 55%. Checked the battery stats and it's been online for 9 hrs. If I plug it in while powered on the charging icon displays as if it's charging. Just tried leaving it powered on and connecting the charger and just leaving it. If I hit the power button the charging icon comes on, so maybe it is charging, just incredibly slowly?

My cable went bad within a month. Luckily, every other item we own seems to have the same micro-usb slot, so we had a ton of other cables to try, so that fixed it. But two bad cables - I wouldn't guess that.
Try to unplug the battery and replication it again. Open the back cover and do that. You need to be carefully and not to break the pins.

Last night, the battery of my N4 was getting really low, so I plugged it in. I noticed it was not charging when I plugged it in. It ended up dying completely on me. I plugged it in again later that night, and the LED started flashing red. I unplugged it and replugged it a few times, and now when I plug it in there is a solid red LED and the device is totally unresponsive. I let it sit on the charger all night and it made no difference. I was totally stock, no root, no kernel, bootloader was even still locked.
Am I going to have to RMA? I'm a college student and don't exactly have $300 sitting in my account at the moment..

Find a torx screw and reset your battery.

you really need to hold it for a while, longer than you think. im pretty sure when it happened to me i had to hold the power button for around 30 seconds after unplugging it. if theres still no dice then it might be ok to freak out lol

You've got to open up the back of your Nexus 4, then unscrew the battery connector, take it out then plug it back in. There are some tutorials around the forum if you need them.

I have this same problem, I've already taken the battery connector off reset it nothing there, removed batter tried to ,annually charge using some wires on + and - terminals still no dice.
I'm afraid my warranty is void because of those procedures. Does any one know if that's the case.
I still have solid red led when I plug it, and I had solid red led when I plugged in with no battery, does anyone know if the battery is just completely dead and needs to be replaced?
I had a similar problem on one of my Nexus 4 phones - I went to the LG service centre to get it looked at. They said the motherboard is gone and needs to get replaced. If your phone is still in warranty then you can get it done - otherwise replacing mother board is a very expensive affair - you would be better off buying a new Nexus 5.

Is it time to trash the N4
My Nexus 4 went low on battery power (3%) so I plugged it in to my usb car charger, soon after i noticed a solid red led light coming from the notification led. I left it on charge for close to 12hrs once I got home. Pulled the rear cover off and removed the battery to test the voltage... 3.8V was available. After reassembly and many different attempts at button pressing combinations there is still no life whatsoever and when I plug it into the AC charger I still get the solid RED LED light of Death...
Can anybody tell me if the mainboard is likely to be fried???
unfortunatly my Nexus 4 fell into water and Iv'e tried the rice trick and it didn't helped. now after few weeks when I plug it to the charger I get a solid yellow notification light (sometimes it gets red too).
I just wondered what does it mean. it says the phone is just dead?
How long did you charge it?
Yellow light normally suggests it's charging. Let it charge for 3-4 hours and then see. But before this make sure that there is not water inside the phone.

I replaced the battery yesterday from my friend's nexus 4 and it's still the same (the battery was half charged on his phone).
but the phone can be dead even though the battery charging right?
