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.
I plugged in my razr before I went to bed. I've been using a HTC plug and cable for the last few months no problems. Woke up this morning and battery was at 5% and then the phone died completely soon after. I plugged it in using my original motorola plug and cable. The dual core screen came up and then the battery level said 0% and it looked like it was charging. It died again after about half an hour. Now nothing will get the phone going. I also tried the hard reset (Power and volume down). The phone is unrooted and hadn't been updated to Jellybean yet.
Any ideas what I can try?

Try using the correct charger and charge it for about an hour, thats the first thing I would try. How long is the htc cable you're using because the longer the cable the slower the charge.
I have tried multiple different chargers with no joy. I think the problem is with the connection. When I plug a charger in the white charging light flashes briefly for a second. I checked the connection for dust and it looks clear?
Try Booting into bp tool or hw diag (hold vol up and vol down then press power should see black screen with white text vol down moves cursor vol IP selects) the phone should charge if left in one of these modes (if you can even make it this far without the bat dying that is). if that don't work could try disassembling then charging the battery directly (never tried this its only an idea try at you own risk)
My xt910 razr maxx has suffered exactly the same fate overnight. Worked fine yesterday now it's dead with the only sign of life from the white led when attaching the moto usb charger. Phone wasn't run flat prior to this. Baffling

Yes I have and no button combination produces as much as a glimmer. I've had the back off and checked the battery for charge, it shows 4.3 volts so it's not that. Something has failed catastrophically I fear.
Check the battery's cable that connects to your phone.If that cable was broke,you can just see the battery level but without charging it.

I've read around this a little now and have invested £3 in a Motorola Factory Cable of fleabay which hopefully will resolve the issue. Due to be delivered next week so I'll keep you posted......
Well got the factory cable and tried it holding the vol down button. Nothing. Took the back off the phone and checked the voltage of the battery 2.75v. Removed the battery and tried the factory cable with vol down. Still nothing. Reinstalled battery and left charging off a pc overnight, this morning it had risen to 2.83v. Starting to think that this phone has had it
Cut the end off a micro usb cable, exposed the wires and connected the red and black to the battery terminals then plugged it into the moto wall wart. Left it until fully charged....volt meter read 5.1v, the output of the charger. Disconnected and checked charge, 4.2v out of the battery.
still dead. Nothing. No red moto screen, no recovery nothing. Something else must be amiss. All I get is a brief white led flash when I plug in the standard charger cable.
anyone have any ideas where to go from here other than the skip?!
Just resurrecting this thread in the hope someone has found a solution....
I still have a brick which is unresponsive to two factory cables plugged into my PC with and without the battery in.
Trouble is I've got pictures on there I'd like to recover if possible which causes me to persist with this troublesome device!

I access the boot menu by holding both vol up and down, and pressing the power button (hold for ~2 seconds, and release the power button, while still holding vol +/-. Volume down will only send you to APFastboot. Check out the post, I encountered the same problem. The final method I tried was the winner. Good luck, and let me know if you have any questions.
Thanks for that, I'll certainly give it ago when I get a free hour one evening this week. I am concerned though that the factory cable doesn't work, I was under the impression that the phone should at least respond to its connection in some way - it doesn't even when vol-is depressed when connecting to pc.
The only response I get from the phone is a brief flash of the white led as the usb cable (factory or charging) is connected to it.
That indicates that there isn't any power management remaining on the phone, and the battery is pretty weak. You'll need to get the battery charged up manually. After you flash with the last method I used, you should be able to reconnect the battery and charge the phone all the way up before booting. Sounds like you're having the exact same problem I did.

Really , Really wanted this to work but it doesn't look promising.
Made the USB charge cable as described (white and black twisted together to -ve, red on its own to +ve). Battery removed from phone, usb on charge cable connected to PC.
5 Volts found at the battery connection terminals. Original Moto Data cable connected to phone then PC. White LED flashed on for slightly longer than before then off. No response from phone - nothing on the screen or vibration with or without any combination of Vol- and vol+.
Battery refitted and charge lead attached to terminals as above to charge from PC. Now reading 4V across the terminals charge lead plugged in, 3.84V cable unplugged so presumed charged.
Still no response other than the brief white LED from the phone with either the Data or Factory cables and Vol-(or any other Vol configurations).
Any ideas???
I assume you tried pressing and holding all the buttons, for five or ten seconds, or even a little longer, to try a full reboot. Beyond that, I wish I could help more. I'm slap out of ideas. This was the last step for me (as the solution usually is). The main board might have had it, though I don't have a clue why.

I'm thinking dead mobo too. When it died it did so overnight without provocation - no flashing or tinkering, it was left on the kitchen sideboard and found dead in the morning. oh well I've tried. many thanks for your help:good:
Glad to try and help. I guess it's time to move on to the next device! Let us know if the phone sporadically decides to work, or you figure out a solution!

I am not sure if you already watched this video, its for droid razr maxx, charging a dead battery and works perfectly for droid razr too.
My droid razr was exactly in same condition, white light and no charging, did not power up, completely dead.
I popped open the back case, connected the modified usb cable wires to the positive (Red wire) and negative (black wire) ends of the battery and let it charge (stay connected) for one hour. Then i pressed vol up+ vol down + power button. And my phone switched on.
If only your battery is dead, this should work.
Anyone getting the sleep of death on their XTZ2? I'm running completely stock (not even rooted) on 23.0.1.A.4.30 and just experienced the unit not turning on at all until I do power + up volume.
Upon returning to life, the battery was 90%, so it wasn't battery.
Had a bit of a panic attack until I googled the solution (power + up) but this is the first time its happened to my unit, could it be related to the recent upgrade to 23.0.1.A.4.30? Anyone else seen this?
Mine lasted a day and a half after the 23.0.1.A.4.30 update and then became very erratic and kept forgetting wifi login info.
Did a restart and certainly got a sleep of death OK.
Would not switch on at all.
No power + vol up or attempt at repair via PC Companion made any difference to it.
Since gone back to Sony for repair, that was weeks ago, who knows if /when they will return it.
I had the same problem with mine as well I have the 561 the Verizon model. I have received a replacement but have not been able to get it to turn on either. It shows no signs off life at all not even when connected to power AC or PC. My old one would blink red and go dead when connected to a PC but this one doesn't even do that. I haven't had time to call for another replacement yet but really two defective devices in a row the second one didn't turn once.
Finally got mine back from Sony repair agent.
Worked fine for 3 days, then failed to power on again as per original fault.
Once again returned it for repair.
Think I'll give up and buy an iPad instead - at least they seem to be reliable and consistent.
This just happened to my tablet this morning. Tried all options under the sun but can't get it to boot.
I can't even do a factory reset and I don't particularly want to return it under warranty.... :'(
Mine is an xperia z2 tablet sgp561 (USA Verizon) build 17.1.D.0.437, stock 4.4.2. This issue happened to me 5 days ago after I powered off the tablet, it won't turn on again. Battery charge was ~70% at the time. Plugging it with factory Sony usb charger won't do anything, charging status LED remained Off, power button unresponsive. I let the tablet sit for 2 days without charging cable connected hoping the battery will drain completely by itself and the buggy firmware will restart executing at its base address getting out of the bug. Then I connected the crap to a fully charged 15000mah Anker power pack and alas, the charging status LED glowed red and after ~5 more minutes the LCD screen turned On for ~5 seconds showing a big battery icon at the center of the screen indicating 0% charge. Waited about 1 more hour and the charging status LED turned amber. This time I did the "power button + volume up" ritual holding both buttons for 10 sec+, expecting 3 vibrations but didn't feel any. At this point the tablet is still powered off. Because LED = amber, thinking battery must be at least 10% charged by now, just pressed the power button for ~2 sec and surprisingly the normal power On vibration came followed by Sony logo on LCD screen and the rest is normalcy.
From what I can remember, the recent change I made before this problem happened was turning Stamina to On in the battery settings (factory default is Off). I reset all settings back to factory defaults and so far so good.
Finally got mine back from Sony repair agent after about 3 week wait.
Seems to work OK now, fingers crossed it will keep working this time.
The note that came with the return indicated that they replaced the mainboard and battery, which is a better solution than their first attempt which was just to reflash the software.

Dude same thing, WTF is going on, I tried plugging it into charger, nothing. And once I got the msg of red colour battery icon and then I plugged it in. then it started charging and I was happy so I turned it on the it wasn't charging,
Please update me what happened and what they are saying cause I am about to send mine to get it fixed.
Edit: seems that by replacing the battery and mainboard has actually fixed the issue? Guess it's time to send it back to them, Gosh

Did this method work for you? Plus did you come across like it was charging but it wasn't really charging,(like it showed the low battery stat with orange/red colour LED notification but suddenly it vanishes) then it's not responding at all.??
I had this issue 2 times with months in between , no response from power+vol up , no lights when charging , no response from pressing on the red button behind the flaps.
The last time it happened i tried putting it on the charger for a whole day with no result, then decided to let it rest a few days first , since someone had the same issue and it magically came back to life when he got back from a vacation.
So i try to turn it on 2 days later and the tablet to my surprise responds again with blinking red LED, recharching afterwards did the trick and worked again since
In my case i was running CM11 at the time, both times it happened after an update which required a reboot while, still mistified about the cause and the fix , i presume it solved itself by letting the battery drain.
Since then i reverted to stock rom just to be save but havent had it happen since, this also seems to have fixed some touchscreen problems i was having at times.
Hope this helps.
Bloody hell, I've just ordered mine today!
Don't stress. Mine got repaired. if it goes tits up that's what warranty is for
What did Fonebiz indicate was wrong with your Z2.?
They replaced the motherboard in mine.
Exactly the same, works fine now
This just happened to me today. So seems like overall suggestion is to try and let it discharge. The try to start it back up and charge it then. Just want to make sure that's the only potential solution now?
No! Leave it powered off, put in on a known good charger for at least 12 hrs. Don't touch it in that time.
If it does not come alive after that, send it in for repair.
ok..let me try that. I originally tried that and nothing occurred. However, I just found the OEM charger and usb cable and will try that. Unfortunately it's a Verizon version so sending it in will not be covered by Sony warranty. Per the Customer Service that I called.
ok..tried another charger and the red light came on, but it's been over 12 hours and still no go. I did notice that the red light was no longer on (from overnight charging). I left it unplugged for a bit and reconnected. The red light came back on but still no response. Sounds like i'll need to send in?
Looks like it.
Had the same problem on tuesday. Impossible to switch on, no light, none effect with charger, none effect when connected to PC/MAC etc...
After 4 days without charging my Z2, it came back to life, showing only a big red battery icon when pushing some seconds on the power button. Connected to a charger the red led indicator glowed ! (red battery icon is totally different with the original icon when tablet is charging in power off mode)
After a full battery charge with OEM charger and after a normal power on, my Z2 is now perfectly functionnal.
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!
Hi,
I had a Sony Z5 compact in a drawer for about 2 years, where the battery already was weak. I'd like to use it as a smarthome button panel where the bad battery won't matter, but I can't get it to turn on anymore.
When I first plugged it, the status LED switched to constant red. I unplugged it a couple hours later, just to find, that the LED stayed on even when unplugged. The device still was cold, so I don't think, that it really charged.
Since there was no reaction on the power button, I tried the "OFF"-button in the SIM slot. After reading on the internet, I held that button for 2 minutes. The phone vibrated every 15s, so it seemed alive. I then plugged in the charger, again the status LED turned constant red. This time the device got warm, seemingly charging.
After a couple of hours I tried starting it, but still, theres no reaction on the Power button. I again tried the OFF button, with no reaction whatsoever, not even vibrating anymore. Also the status LED shows no more reaction on plugging it in.
Is the device dead now? Anything I can try to get it working again? I don't need the battery anymore, Its supposed to spend its second life permanently plugged in.
best regards,
RockNLol
The usual advice is to make sure it is off (Hold power and vol-downup until it vibrates 3x / if really dead, just wait ~20s), and then leave it on a charger for a few hours. If that doesn't do it, your battery is toast.
Even if it is revivable, there is a chance that it is so weak that it will make the phone crash - the battery is used like a buffer even when on the charger, and if the phone needs high peak current, it will try to take it from the battery. If the battery is too weak, voltage will drop and the phone will crash.
In any way, I would not want a battery that is potentially damaged to be at the charger 24/7. If you deep-discharge a battery, it can form tiny little short circuits, and if you charge it, it can become a fire hazard. As in, burn your house down and release lots of toxic fumes while doing so.
If you are familiar with soldering, the best solution would be to open the phone, remove the battery, and replace it with a fake battery circuit. Obviously, don't do this if you aren't comfortable doing this kind of stuff, and always have a plan for what to do if the battery decides to light on fire.
For that, after you removed the battery, try to pry off the yellow tape on it, and get to the battery protection PCB near the connector. Carefully cut the leads to the actual battery and remove it (this is the most dangerous part). Then, solder a large capacitor across the battery leads and a connector for a power supply that can provide around 4V at, idk, 2-3A. There aren't many 4V power supplies, but a 5V one and a (silicon) diode in series work well (make sure the diode can survive a couple amps). Then, plug the fake battery back into the mainboard, fix everything in place using tape or glue, and see if it boots.

The usual advice is to make sure it is off (Hold power and vol-down until it vibrates 3x / if really dead, just wait ~20s),

Power and Volume-Up?
Sure, one of the two
Power + Volume-down starts TWRP when the device is not running.
When the device is running, it takes a screenshot.
