OK, I've seen this twice (so it isn't complete death) but wanted to see if anyone else had any ideas. I've done a complete shut down (power button for 8 sec) and then couldn't get it to turn back on. When this is happening, I can plug it in and see the green charging light. Holding the power button then for 8 sec will make the green light go out. Pushing it again, light comes on. So the button is working... If i leave it for awhile, the nook will then reboot and appear to work normally...

If your device battery level is below 10 percent it will not turn on until it charges up to at leat 15 percent level. Then it will turn on.

I think that is the mechanism stopping it, but it is malfunctioning, I'm at about 90% this last time...
Is there ther equivalent of 'battery stats' somewhere that can be affecting this? or is this hardware? It should be turning on fine at 80-90% but no. However, plug in for 10 mins and it works fine. So that seems to be the problem.

OK, this is getting worse, I'm now at 100% charge and it happened. Weirder still, if I leave it plugged in for awhile, it will reboot on its own.
I have not had this happen on my HD but something similar has happened on my HD+. It seems to be related to whether an SD is plugged in. I have to take the SD out, press power off for a while, then release and momentarily press power again.
I know on the Nook Colors, they would not turn on unless it could find the boot files to boot from. So if a user formatted his internal boot partition by mistake, it would not turn on unless a bootable SD with active boot files was in the slot. Something akin to this may be happening, only in reverse.

OK, this seems to have worked. I tried to change the partition of my CWM SD card using EaseUS, but that seemed to make it no bootable, and removing it does seem to have worked. Now I can boot a new reimaged CWM card.
Thanks!
Good to hear that your nook is working again.
It seems i am having a similar issue, only a little more severe.

Something similar happened to my HD+ running the 12/31 build of verygreen's CM. In my case, I think it was precipitated by the battery draining too far first, though. Very weird and a little spooky, but glad there's a workaround.
Wow, this is dumb. I can't believe a badly-formatted SD would cause it to look like it's broken. Put a message up or something. Thanks for the help, thought something was really wrong!
Nook HD Plus won't charge
I've seen dozens of reports of this. The symptoms are all about the same.
The unit drains the battery, even if you plug it in, it still drains, so although the charger and cable are fine, something inside the Nook doesn't get the memo.
It drains down to the point where it turns off. Then every time you plug it in, the light goes green, then amber, then off. The battery never charges.
I tried taking the unit apart and disconnecting the battery overnight, but that didn't seem to help. I suspect something in the software gets in a "vapor lock" where a dead battery condition is mistaken for a fully-charged battery condition. I only paid $109 for it refurbished, so it isn't worth another $60 for a new battery, and I don't think there is anything wrong with this battery.
If I knew the pinouts of the battery connector, I might try charging it without going through the Nook. Perhaps if it was actually fully charged, the "vapor" would realign.
Does anyone have another idea, apart from the nitwit stuff Barnes & Noble allows on its forums, like "push the cable in harder" or try another adapter. I notice they aren't interested in entertaining any idea that their firmware is at fault.
It will not charge when plugged in if OTG USB is activated (e.g., to connect a USB keyboard). That's happened to me a few times using unofficial VG CM versions where the USB state can be changed inadvertently from a pull down drawer. If the USB isn't toggled back to normal in time to recharge the battery before its completely discharged, it might not be revivable.

I've the same problem, except even if I leave it a while, it doesn't boot or even appear to start. Is there something wrong with the battery or display? It was working perfectly fine until suddenly the screen froze and I had to do a complete shut down.
I cant get my nook to turn on. I try charging it and a little green light comes on at the bottom and stays on for about 3 seconds and then a orange light comes on for about 3 seconds and then it shuts off. I dont know if the light is supposed to stay on while it is charging. Sometimes it comes up with a dead battery sign but it just goes right back off.

Have you tried charging it with its wall-charger for an extended period (8+ hours)?

My nook was idle for a day or two, as I remember I hv shut it off.
But then yesterday I try to charged it, the light was green then turn to red, n then it went off, usually the nook would turn on right after I plug the charger. So I didn't notice it until today, and I tried to turn it on by pressing the power button, and the N button together as well, both didn't work.
It seems that I can't charge it or turn it on. Everytime I tried to re-plug it to power or press power button while its connected, the light went on in green to red then off again.

Connect your charger. Let it stay on charger 20 min. Then try push n button. If this not bring screen on then try push power button for 5 sec. Again if not then try power and n button combination.
Hope this helps.
Thx! Turns out tht external charger didn't work.

I think that last opinion is make CWM sd card (without CM10) and insert it do device, then try to switch the device on (with charger trick or power button). If you then get it live all is ok. If not then last change is wait when battery goes empty and charger wakes it up.
Actually i predict that item is itself faulty and you must return it for change (maybe not faulty at hardware side, only OMAP inside code got corrupt).
I don't know, that might because I rooted my device, and I did sth wrong. Sometimes it would reboot itself, since my cmw card was inserted, it would load tht root page so I found out. But I live in Asia so returning the device might be too costly, probably won't do it.

It could be several things. The most likely is it was trying to update itself and could not because the CWM card was there. I don't think your device is defective.

Now i can say same. With first information things was other.
...It's more or less a known bug to those of us who use CM10 (even to some who use stock), the battery simply often can't tell how much she has left. So she may fluctuate from 1% to 26% to 0% a moment later . In one such moment my Nook HD+ shut down (went from 26% to 0%). So I put it up for charging thinking (naively) that it would boot up ... it didn't, now all I get is a charging icon that never goes away (orange led remains lit). What's more I *know* it has some charge (the "26%" was the right value) and I know the battery works, so what prevents it from starting is the "battery charge sensor".
It's a pretty silly way to lose your (my) tablet over. Even more so given how much I grew attached to it for my workflow. So what's next? Is there a secret way to convince it to boot. As I said both the hardware and its software is in top condition. I guess an alternative would be to ship it back for replacement but I'm afraid that I've lost my receipt and -as I said- it's a silly way to lose your tablet over, there *has* to be a (fast) way out...
BTW when connected to my PC my device manager briefly shows an "Omap 4470" unknown device (with an exlamation mark) which goes away few secs later, so I cannot attain ADB control over my devices either (sadly)....

If you are running CM10 or 10.1, there is an easy way to connect with ADB. Do it wirelesly over wifi. That is built into CM. Just enable it in the developer options. No need to mess with the USB cable and windows drivers. You can do the same thing with rooted stock by installing an app called ADBWireless.

At the time that could not happen , since (as I had implied) my nook was not booting to begin with...
Anyhow, what I did was to leave it for three solid hours on the charger, and after that period of time it booted on its own wiithout warning. It's the first that such behavior was/is ever present to my nook and it's deeply worrying. A battery fix for the CM kernel couldn't come any sooner; now, if only verygreen was around
There's a few ideas on a couple of other threads including putting it in the fridge, etc. Question, if you plug it in, does the charging light come on? Does it come on after pushing the power button or the N button? If so, take your SD out, leave it charging overnight and try again. It often reboots when in this state and if there's an update problem, that could be the issue. Also, it is sometimes erratic on when and how it charges, be careful with the connections.

As I said it came up on its own, without warning after leaving it for 3 hours on the charger...
As for your question, the led (charging light) was on all the time but it would only show me that it had no battery (couldn't charge even though it was ... charging?)
Maybe the fridge makes sense in those situations, as it was indeed into a (relatively) hot environment and maybe it couldn't charge as a safety against overheating and since (at the same time) it also thought it had 0 battery. But what I can't understand is why needed 3 hours before starting to charge up, it was already cool enough long before ... strange things are/were happening with my battery all along and I worry...

Yep, I've noticed the same thing a few times. It no longer panicks me. When it doesn't turn on, I take out the SD, plug it in, wiggle the connector a few times, and let it alone. So far, it has always eventually rebooted, often as you say on its own. Quirky, but not fatal at least. One poor guy on here never did get his to turn on, but the key was the charging light,his didn't come on.
Need help cannot turn on Nook HD+ at all
Hi!
I cannot turn it on at all and it won't reboot.
It went out some point I didn't watch it. When I connected it to the charger the LED next to the connector starts blinking amber and green for a few seconds and then stays blinking red and makes a high pitched noise.
The only reaction I get is when I press power on an volume down after some time - it display turns on an shows a charging sign - but it never really seems to fully charge. I left it on the charger over night - still the same. Once the display blinked and showed “nook” but went out immediately after a few milliseconds.
Might it be some kind of bootloop!?!?
What combination to press to make a reset?
Thanks in advance for any help

Well you tried everthing I've seen or could think of... though leaving it on till the battery runs out would be a curious test? If it will even do so.
Edit: You didn't state how long you tried charging it for. If it drained all the way it can take a good amount of time and WILL get stuck at only the backlight just like you have.. The charging symbol shows up later and will finally boot at around 15%'

Since i cant see anything on the screen i can only go by the light next the charging cable. I charged for for a whole day and the light was green on the tablet stating it is charged 100%. i did not try to drain it. will probably take a week or more since i unable to use it.
Unless someone has another suggestion i think it time to throw in the hat? the tablet is only 2 months old so it shouldn't be a problem returning it to the store and getting a replacement

I just researched info on the emmc brickbug in the event you were testing or running the rom with trim enabled. Or lagfix too. The brickbug can brick the device where it doesn't turn on. Just something else. Or that is from what I understand anyway.
But it sounds like you might as well take it in for replacement.

So... I had my Nook HD+ plugged in to my laptop for adding new video files. I went to unplug it, and it said something about "Powering Off" on the screen. I waited until it was off for about 2 minutes, then tried turning it back on. First by a quick press of the power, because I didn't realize it had completely turned off, as it had never done that before when I unplug it. Then I have been trying full 10-second press of power, and several tries, NO POWER! I have no idea what the heck happened, I have been using this tablet with the new CM10 version mod, and have not had any issues. I usually have it in sleep mode and on the charger cord. I was getting ready for a day trip in the morning, and now it's like a paperweight.
PLEASE HELP!
When you plug in the charging cable, does the LED light register anything at all?

I assume you mean the charger? I had it charged to 75%-80% before I'd put the new videos on it, so I didn't think that had anything to do with it, it shouldn't have been dead already, but I did plug it in to the charger so it went to full power, and for a long time it just showed a battery with a bolt on the black screen, but now it appears to be working.

Try removing your SDCard and turn it back on, welcome to the weird world of Nook. Put the card back in once it has booted up. Can you let me know if this at least lets you boot.

Well, since I already got it working again, I will just hold on to your suggestion for when it crashes on me again...
Seems I cannot find any other people asking this question
Basically I have Nook HD+ rooted and CM10.1 and it works great. I have google market on there and the original Nook OS has been sent to the nether region of hell where it belongs. So it's a pretty decent basic android tablet.
But when I let the battery go to zero and it shuts itself down, it seems that it doesn't turn back on so easily.
I'll charge it overnight and then attempt to power it on, but it doesn't do anything. I see the screen backlight come on but no "nook" logo.
So then I try plugging it back in and hold power and the "n" for 10 secs or so. I'll see the screen turn off.. I'll do that a few more times and finally I see the dead battery logo show up..even tho I charged it all night.
So then I let it charge a bit longer and try again with it still plugged in and finally it turns on.
I was just wondering if others saw this and if there was some proper method I should be using to restart it to avoid this.
Yeah, my nook was doing that same thing for a while. Now though, I let the battery die and I can't get the thing to turn on at all. No backlight lights up, no battery charge icon, the thing's led just glows green for 2 secs then flickers to orange and stays orange for a few secs and then the led turns off. No matter how long I hold the power button or the power plus nook button, nothing happens. I hope my tablet isn't dead forever. Anybody else have this problem and find a way of fixing it?

Just keep trying.. i noticed my backlight was so dim that i wasn't sure it was on either until i turned off all lights... then after holding power for like 12 secs i saw it go even darker so I know my backlight was on now.. but like you said.. no logo. Just extrem0 said.. you gotta keep playing with it, unplug it, plug it in again, etc.. it's really hokey. I've been sure to keep it charged up since my last post so I am just avoiding the problem. But it is stopping me from recommending a modded nook to my friends and family because the first time this happens they will come crying to me to help them.

I also have this problem on my Nook HD+. I don't think there is a solution for it, so I'm going for a warranty.
However, before you go for a warranty; flash the stock ROM back on. You're probably think how do I do this with no battery? Well, once your Nook boots up, your tablet will not charge at all. So, we need to charge your Nook whilst it's powered off. Again, how do I go about this? Well, turn on your Nook charger from the wall socket, but do not plug it into your Nook yet. Now, hold the power button on your Nook (ensure that your have no battery at all, and that your Nook does nothing when you hold the power button). Whilst holding the power button on your Nook, plug in your charger. It should turn green, then turn orange. It should stay like this for a while.
Give it a couple of hours, and it should charge up to around ~60% (you may be lucky if it charges more). With that much battery, put the Stock ROM back on and go for a warranty. Don't rely on this method for too long, as with time it will also stop charging with this method. At the moment, it will not charge when the Nook is turned on. Go for a warranty whilst you still can.
All the best.

I recently went on a 3 month trip. Before I left, my nook was working perfectly fine, when i got back, it didn't work at all. It's not dead because i left it plugged in overnight but it still didn't turn on. when i plug it in the LED goes from orange to green and then off (or green to orange, i can't remember). The screen doesn't turn on at all. I can't get to recovery either.
This is a Nook HD, I believe it had CM11.
:crying:
Can this be fixed
or should i plan it's funeral
Same here
The same has happened to me. Screen doesn't turn on, but there is power, I can play it into my laptop and something is there, just not enough.
Good excuse for a new tablet!
It can be fixed. I've done it before. It has to do with the fstrim not being compatible with certain hardware versions of our device. If I can remember how I fixed it, I'll post it here. Trying to fix mine (again).

If would be fab if you could fix. Seems to be a common issue
I was able to fix it. YMMV.
1) Make sure the Nook is completely off and unplugged
2) Take out your sdcard
3) Hold down power button until the "battery depleted" icon shows, then promptly plug in the power before the icon disappears.
4) Let it set. The screen will go black, then it will attempt to boot and get stuck on the faint black screen, but this time, the charging light should stay amber.
If you want to be safe, wait until the device reboots itself. That could take hours though. If you're plugged into the wall wait at least 30 - 45 minutes before holding the power button down til it shuts down and then rebooting it (with the sdcard inserted).
Good luck, I hope it works for you.
EDIT: Also, I've read this may also have to do with wifi sending the device into some sort of strange bootloop when the screen is off. I personally believe it has more to do with the fstrim of JB but perhaps changing the wifi sleep policy may prevent this issue from happening again. I'm skeptical, but figured I'd pass that info along if anyone wants to try it as well.

Not sure we have the same problem. My screen doesn't come on at all, I don't get a battery depleted icon, no matter how long I hold in the power button. The only sign of life I get is when it's plugged in, when it goes from orange to green after about 10 seconds.
Thanks for the help, but I think it's a lost cause.
YMMV. But mine was the same issue. You should be able to get the icon by holding the power button down for 5 or 6 seconds. I'd say just eff with it until that icon appears. Try different button combinations. I used power and home trying to get the icon to show.

Anyway... since people are continually running into this kind of issue...
Give or take 21 seconds after turning orange it turns green during actual boot cycle into rom
Give or take 10 seconds after turning orange is cwm internal recovery.
After about 10 seconds the charging screen image disappears.
The charging screen image once finally no longer may not show up again until full power off/on (holding power button > 10 seconds or full battery discharge). Unplugging and plugging back in does nothing except making the device look bricked if there's too much light shining on it.
Device may not automatically leave the above state under a specific situation(s). May still need manual full power off/on.
Guessing 10 seconds could also be something else during the early/late boot process or other. The light changing color though should indicate that something is indeed happening.
Light should stay green during the boot process if its completely and fully no questions asked 100%. If you go based on that than yours doesn't appear to be completely fully charged which should either mean its turning on and using battery or not charging correctly.
The light turning off is curious. The device could be shutting off. If light comes back on a moment later then the device has rebooted. if the light stays off = n/a.
If its booting into recovery then the device would be available via adb. At that point it could be further evaluated.
On the off chance the screen was damaged it should boot and usb should be available via computer as well as adb.
If not then its probably toast unless its simply not getting a good enough current causing mislead battery stats and/or not enough energy to get to charging screen (bad wall power adapter in use, damaged power cable - though could be bad battery, defect, damage or whatever). OR there's some major error on behalf of the user happening (think should have tried that in the morning not while 1/2 asleep or came home from long trip and forget how that works).
Maybe the only other things are the emmc brick bug, was left sitting in the sun or heat or ocean air or other physical damage/defect even to the power port as well.
Or maybe it was mad that you left it. Shouldn't have hurt its feelings you know. At least its not crying battery acid on you.
That should just about cover everything except for the things not mentioned. Since its your device, you decide what happened.
Its complicated so anyone see any improvements, clarifications, or mistakes? Please put it in a post.

Bumping this thread to make it aware that there is a real answer. I have been able to duplicate this problem and rather easily too.
The problem is indeed from bad power. The device isn't receiving the correct amount of power needed to charge and start from a fully discharged battery.
To safely* duplicate this you can use a usb extension that isn't fully connected to the nook power cable. You may need to fully connect it first then slowly disconnect/connect till the light turns green when it should actually be charging. It won't actually charge in this state, or if it is, its very little and the battery percentage will continue to drop.
Leave the cable as is and unplugged. After the tablet is fully discharged, connect the usb cable. The light will change through the modes and turn off. The device will not turn on.
There are probably other ways to cause the problem like for instance a portable usb battery that doesn't put out enough juice (not the orange kind). Etc.
* It didn't hurt mine, but not my fault if it breaks your device.

I actually ended up fixing it yesterday!! I haven't touched it in about 3 months, and I was planning on just throwing it out getting rid of it some how. For the heck of it, I decided to plug it in, assuming that it was gonna go through the same process. But this time it went from green to amber, but it never went off. So I pressed the power button and the battery icon appeared. This was a really good sign. So I left plugged in for about 5 to 10 minutes then tried to power on.:fingers-crossed: As soon as I saw that '' Nook" boot up screen, my heart stopped. It booted up perfectly and I almost blew up from excitement :victory:. So I then flashed the stock firmware back onto it, so this would never happen again.
I guess the battery had to be completely depleted or just had to cool down. Idk but either way this was one heck of a miracle
So I recommend for anyone having this problem to just leave it off and don't mess with it. I wouldn't say for 3 months like I did but maybe test it each week or wait a month if you have good patience
Wow. Man, that's awesome! Glad you posted that update on it. Thought if you had posted an update it would be the opposite as in trashed it
Actually, I guess only you could answer if you had also moved/unplugged the power cable from the wall adapter or put it into a different wall adapter, etc. Thinking there could have been a difference there.
These modern day devices are so finicky, guess anything is possible. Like you say, maybe sitting without power is another answer.
From some experimentation I have etermined that your power adapter (that plugs into the outlet) is the issue. It does not like to be leaft plugged in indefinately. It will continually use power even when the nook is not plugged in.
Also, if you use a differnt adapter you will have the same problem unless it is also of the exact same voltage and amps.
