Hey Y'all,
I helped a friend of mine root his NT awhile back, and it was working fine for months. I showed him CM7 running off of the SD card and he liked it, so I set it up for him on Friday. I did a factory restore on the NT, and he reentered his BN account info. I then booted off the SD card and everything was working fine as I could tell.
He brought it to me this morning and it won't charge. The "n" is always green when plugged up to the wall and it never goes orange to indicate it is charging. But when I attempt to power it on, it is always displaying the low power message and says to plug in the charger.
What I have tried:
-I removed the SD card, and it still won't charge... (not that it would matter).
-I have 3 chargers and my own NT. When I plug a charger up to my NT it works fine and the "n" goes to orange. But when I plug the same charger into my friends NT, the "n" is green and I can't get past the low batter warning.
-I have had my friends NT connected to a wall charger for about 3 hours this morning and I still can't get it to boot.
Any ideas on what might be wrong and how to fix it?
Thanks for your time.
I found this thread and tried both of the suggestions and my friends NT still won't charge or boot.

The same thing happened to my wife's nook this evening. I think the battery is completely run down, but won't receive a charge for some reason. Her charger showed green also.
I tried, removing and reinserting the SD card and also holding power for 20 seconds. I finally was able to hold down the power and the N button down for about 20 seconds. This did the trick. It showed that the battery was too low to turn on. After about 10 minutes, it booted.
Hmm, I get the battery is too low to power on every time I hold down the power button and the "n" is always green on the charger.
strandedinar, did you have the power cord hooked up when you held the power button and "n" button down for 20 seconds?
So connecting the STOCK charger and the STOCK cable and leaving it alone for an hour or so isn't doing the trick? That's really the most that many of us have had to do... No "n" button needed either.

Yes. The nook was plugged in and the "n" was green. The Nook wouldn't power on - My wife was convinced it was my fault for rooting it...
I left it plugged in like that for 20 minutes, but nothing happened when I tried to start it. The charging light was green. I finally tried the power + N button trick and then I received the notice that the power was too low to turn on. This was the first time I received this message. After this, the color of the charging light changed from green to red/orange and I could tell that it was receiving the charge. After 10-15, it power on and has worked normally since.
I tried every thing I could think of and google and nothing worked. I took it to BandN yesterday. They thought it was a typical issue that they see a lot of, but after 3 folks at the store couldn't figure it out, they called 1800 support. Support said it was a bad usb port and swapped it out for a refurbished model.
I still think I could have fixed it, but after a couple of days my friend was getting antsy for it.
Thanks for all of the responses.

How did you do that? I was trying to hold the buttons and never got anything.
My NT has no juice to boot, but when I plug in a power cord (stock), plugged into stock power charger, it tries to boot up. Power indicator does turn orange, but then it runs out of power once it starts booting and turns off. After a few second it turns back on, and repeats same cycle again. It never boots to the point where it can actually sleep, seems that boot-up process takes more energy than charges could give it.
Try charging it from your computer. Just as suggestion not sure if it will help.

Hello Galets, did you manage to finally charge your Nook? I have the same problem as you have - when stock cable and charger are plugged in - device tries to boot and screen shows up but due to lack of power in accum it turns off and in a few seconds the cycle repeats.
I hardly understand - how it is possible that having mains power plugged it - there is not enough energy to charge and do other necessary things...
---------------
UPDATE: problem solved. In order to solve it, I had to disassemble the tablet and unplug the screen cord, then I put the power cable in, battery charged up for about an hour or so, then I plugged screen cord back in and turned it on without a problem. The down side of early charge attempts is that tablet decided that I had 10 failed boots and it reset my previously rooted device. Now I have fresh and clean stock 1.4.2 version.

how did you unplug the screen cord? I've looked up how to take apart the nook, but I'm not sure which one would the the screen cord. Did you follow a tutorial somewhere, or was it easy to figure out once you opened it up?

ACL3, check this link: http://www.ifixit.com/Guide/Installing+Nook+Tablet+Display/11148/1.
I did not really follow the guide. I was looking for first two bolts to unscrew. The rest was quite simple but challenging - i don't usually disassemble things.
I did not pull out any of the buttons or battery from where they are and simply unplugged their connectors too - you will see 3 small foam rubber black box-like pieces (in step 9 they only marked one of them). There are plastic connectors under foam rubber pieces.
Be careful not to short-circuit anything with metallic tools.
On the attached image I marked the screen connector. I unplugged it by gently hooking it with two small screwdrivers. When putting it back I gently pressed it until I heard a click. And make sure those small slots on connector match with corresponding ones on motherboard.
Also, when finishing assembly I ran into a small problem with corner flap (which covers sdcard) - it did not want to smoothly slide in and out. So, pull it off completely and after putting plastic cover in place and screwing last two bolts, put it back - some small help of small screwdriver will be needed.
Hope my explanation was helpful

thanks, looks cool. I've never taken anything apart before and I'm afraid of short circuiting something. I think I might try this.
Its been day 3 of having a phone that refuses to power on..
I went camping over the weekend and had it plugged into (and charging) my travel charger via cigarette lighter and it was working fine. At one point I went to use it and turned on the screen but it glitched out by the screen turning on then off a few times until i left the screen off, gave it a few seconds, and turned it on again and was able to put in my security lock etc. It does that once in awhile and I chalk it up to a computer booting up and my impatience
Well the screen powered off while reading on my phone, and I went to power on but it wouldnt stay on this time. I got a glimpse of the battery and its probably 85% charged, but upon coming home and leaving it on the charger all night I am still with a dead phone.
There is no flashing white/green/red led light a the front, even when plugged in.
Ive tried all the solutions on these forums (camera + power button, camera + power + volume buttons, removed battery, cleaned with eraser, tried different chargers via wall outlets & laptop, and even the cmd & "bootloader" stuff but the request is never recognized..) I really need some help with this, PLEAAAASSSEE!
Ive never rooted (?) or flashed or did anything of the sort with this phone, its pretty much stock.
**I just tried putting the battery in after a few min, and as soon as the pins touched and the battery was in, the back lower camera light flashed on for a few seconds and then shut off. Still no power to the phone though
I cant find anything close to my problem so I hope someone out there has a new & successful suggestion!!
Thanks all!
Have you tried a new battery? It truly sounds like your battery is gone and doesn't hold (much) of a charge.
Hi All,
I was out a couple of days back and my battery died. No trouble, come back home and charge it up. Worth noting that in recent months battery performance has been poor with a full charge only lasting about 8hours or so. I put this down to a new ROM I flashed as well as natural deterioration (18 month old S3).
Plug into the wall, red charging LED comes on, but the battery splash screen does not. Tried another charger...same. Thinking nothing of it I go to bed and wake up next morning to be greeted by a green charging LED. However, still no battery splash screen. I try to boot...it doesn't. When I "power on" the bottom LED buttons do light up white and go off after a few seconds. When I press the hold button again, they also come on for a few seconds. If i press the hold button while the button LEDs are on, they go off.
This makes me think the screen has broken as both the hold button and the charging LED is doing what it would do...but without any screen activity. However, it was not dropped or put under any pressure in any way. I have opened it up and also made sure the ribbon is undamaged and connected properly. I have tried calling the phone to no avail. It also does not vibrate or make any noises. Perhaps the battery doesn't have enough juice? Its as if its on the battery splash screen, I just cant see it.
I should mention the screen is infact cracked from an incident about 6-8 months ago. It was however, fully functional. Presumably, this will unfortunately stop me from sending it in. It was also using a flashed rom (CM11) and a flashed kernal (Boeffla).
I used a multimeter and measured 3.96v across the battery so that's fine. I can't test the current as I cant break into the S3 circuit and I dont have a resistor on hand to put some load on it.
Next steps?

Try to put it in odin mode (power+vol down+home then press vol up to agree that you are now in odin mode). You should see it in odin.
If you dont see it, your battery or energy system of your phone is broken. Otherwise your screen is probably broken?.

I've managed to get it into download mode and too show up in odin. I can also get it to show the files in Windows if i wait after holding the power button.
This all indicates it is in fact booting up and the screen is broken...
...BUT...no sound...no vibration...and no calls received
Its as if its only half on. Beginning to suspect a catastophic motherboard failure. Is it possible the battery is at fault? Its as if a whole power rail providing for the phone receiver, loudspeaker, vibrator and screen has gone.

Can you try this?

and let it ring?
hi, i'm unable to start my phone. all of a sudden it turned off while being on charger.
The LED now lights dim red (if on charger) and does nothing. Pressing any side buttons do nothing, just the led still lights dim red. Plugging off charger cable doesn't make any difference just the LED turns off.
Can this be due to battery not charging? It has power off shortly ago due full discharge. I plugged in charger, phone turned on for a while indicating charging by LED bright red. Phone was awake about several minutes, then this sudden die.
Any help is highly apreciated.
have you already long pressed the power button until the phone vibrates?
It was solved! The phone kicked in 30 minutes after, now behaves normal.
Anyway curious why the phone didn't start so long. Tho discharged it had power supply.
I replaced battery recently, so maybe a bad contact or the cord dropped out?
Hello,
My phone's battery was starting to have issues so I bought a new one and replaced it yesterday. I've done it recently on another phone (same model) so knew what I was doing when reassembling it, with the right adhesives and everything. Then I left it plugged for the night as this was advised by the new battery's seller. But this is what happens this morning when I try to turn it on:
- Phone doesn't vibrate when pressing the power button, neither when holding different combinations of Power + volume, etc.
- When I plug it this is what happens: imgur[dot]com/fByubwN The screen turns on as it would normally do, displays the 100% charged battery logo and then just dies (with the green led remaining). The only way to turn the screen on is to unplug and plug it again. But the phone itself isn't booting.
Any thoughts appreciated!

I'd say that the battery is at fault. It can be two things:
- it is not correctly plugged (maybe the connector is not perfectly aligned, or one of the pins is bended)
- it is completely depleted, so won't charge at all.
Disconnect phone from charger and try to test voltage on the motherboard with a voltmeter. If you can't read anything, disconnect the battery and test it directly.
Personally I would say the first problem is more likely - a completely bricked battery is not that common.
Actually the battery was fine. I've opened it again and turns out I've kind of messed up with the flex connectors of the motherboard.
So I was able to boot it while it's open but as soon as I reassemble it, the controls are not detected anymore. It's a matter of millimeters, some parts probably don't sit properly, etc.
We spent some time on it with a guy at a local repair shop, the conclusion was that I had to get a new phone, or a new motherboard which is almost the same haha.
Thank you for taking the time to reply!
