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!

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.
Got a problem that I am hoping someone else knows how to solve:
Device: AT&T Atrix 4G stock 2.3.4 rooted (BL still locked)
Issue: Phone will not turn on or charge
Symptomshone suddenly turned off during a phone conversation the other day and now it will not turn on or charge. I noticed the phone was pretty hot when this occurred. Nothing happens when I hold the power button.I tried a new battery and same result. If I plug the moto charger in about half way I can get the green LED to come on but pushing in the rest of the way and it goes off and does not show battery image or moto screen. Plugging the phone into a PC causes a solid green LED. I have tried with a different charger (5.0V 2.1A) and same result as moto charger. If I plug in charger and then add battery and then hold power button it consistently will try to turn on (green led,screen powers up, and moto image for a second) and then it shuts off. I did this a bunch of times and noticed upper left corner of Phone getting warm (where the headphone jack is). I opened then phone up and didn't see any obvious problems. I bent a couple of the large spring pins around the headphone jack out for better connection and reassembled phone. Then it powered up like normal overnight but has been shutting off randomly. I was able to remove battery to get it to boot back up for a couple days but now it is dead again.
Any ideas? I am pretty sure I have a hardware or electrical connection problem. I really appreciated any guidance. Thanks.
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.

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.
