My NookHD+ has been working fine with CM10.1.3 stable on EMMC. The other day I got home and it was dead even though when I used it in the morning it had at least 50% charge. I plugged it in and the charging indicator was slowly flashing green/amber and then would have several quick red flashes and then just go out. There was a battery icon on the screen that was empty and that was it. I tried another charger and got the same thing. I left it charge all night and the next morning it booted automatically into recovery, I rebooted and it loaded cm but only showed 8% charge. Left it on the charger all day and when I got home it was fully charged. (whew)
There still seemed to be issues though. I could no longer get into recovery and when I plugged it into the charger I was still getting the amber/green flashing, although it does seem to charge. I thought when charging it should just stay solid amber, my wife's HD is solid amber while charging. Thinking I may need to replace it under warranty, I have currently gone back to straight stock to see what happens. I sometimes get the flashing charge indicator and sometimes solid amber. Is this normal or is something going bad?

Edit: thanks to this post, my problem has been solved. Thanks!
So last night I went from stock motorola 2.2 to this wonderful-seeming version of CyanogenMod on my UK milestone - the install went flawlessly, but now I have a problem - my battery is not charging at ALL.
While the phone was on last night after I charged it, it was plugged in, first to my PC and then to the wall socket. In both cases, the battery indicator had a ? (question mark) on it.
I thought it might have been some weirdness with battery calibration so I left it and plugged the phone in from the wall to charge overnight. This morning, my phone was telling me to connect my charger (despite it being plugged in) and on removing the power cable, it died due to no battery power left within 10 minutes.
While plugged in from the wall, the battery indicator comes up but again just contains a ? on it. The little white light next to the power socket never lights up.
If I plug the phone in to my PC via USB then if the handset is OFF, the white light comes on and around 10 mins later it gets enough juice to boot up. The problem is that when the CM7 software starts, the little white light disappears, the phone stops charging despite the cable being present, and it then dies 2 minutes later.
I know the battery is fine because it was perfectly fine before I installed CM7.
Anyone else experienced this problem and/or know how to fix it?
One thing I did manage to do before it died was install a battery calibration app that I found on xda-developers - this told me that the battery was running at 3267 mV - any idea if that's good or bad?
(and yes, I'm using precisely the same cable/charger I was using before I put this version of CM7 on, so I know they are fine - they charge a friend's SGS with no problems)

Try plugging the phone into the wall charger, without the battery. Try and boot it up and let it boot. Once it's booted up, give it a bit and try and put the battery in and leave it to charge.
What happens if you turn off you phone and plug it in a wall charger? If the problem isn't in your battery it will charge fully.
When you phone comes up, try to disable the 1% battery steps in settings. I got a problem with it, and after disabled/enabled it worked fine for me.
Hope this helps.
On plugging it into a wall charger, the phone comes up with its special battery charging screen (i.e. a fullscreen battery level indicator) - no amount of pressing the power button seems to get it to boot properly (with or without the battery).
I'll see if I can get in and get rid of the 1% steps thing later, thanks for the suggestion

Dude, that was PERFECT.
Managed to get enough juice into the thing to get into the menu for a moment and was able to disable the 1% battery steps option - soon as I touch that tickbox, the battery indicator switches from a ? to the charging symbol and the phone starts charging. Thanks a million!
Nop dude, you are welcome
My HD7 was having all the problems above, and my charger broke awhile back I've been using a different brand. Until today I went and bought a micro usb charger for a Motorolla V9 and my phone is almost acting normal again. Charge lasts a whole lot longer, my battery indicator doesn't show the phone charging after taking it off the charger and the wake worked at first but just came across a couple times where the screen stayed dim. But I hope eventually that will go away after few times fully charging it.
Hopefully this helps!
My wifi started working again too.
*After my phone was working ok again I tried using the different brand charger again just to see what would happen, and it started acting up right away.
I looked in the previous threads about non-booting but no one I could find had my issue. Bought the Nook HD+ about 4 months ago and rooted it and installed Android (not sure which version but cm11). Out of the blue, last week I pulled it out of my bag and the battery % was flipping between 1% and 31%, so I put some stuff on it via USB and then shut it down to charge. I plugged it in overnight and tried turning it on in the morning. All I was getting was the low battery picture, so I kept trying to charge it, but it wasn't charging, the power light would go to orange when I plugged it in, thena fter 3-5 seconds it would flip green and then turn off and retry. My assumption is the battery is dead, but it could be a corrupted OS now as I got it to charge long enough to get to the CM11 boot menu. But I even went out and bought a new charger and converter to rule that out and it still is stuck in the same boot sequence. I obviously can NOT charge this thing while it is off because of it's reboot loop, it can't charge. I'm not quite sure what is going on or whether it is a battery or boot issue but after I leave it for a big it freezes on the cyan picture (which is frozen on some scrambled version of it) until I turn it off.
I can't power it on enough to charge it to rule out the battery, I tried holding the power and n button for 3 seconds, letting go of the power, and then pressing it again to get into the recovery menu, but that isn't working either. And I prepared another SD card for a second flash for a corrupted OS and that didn't seem to work either.
I'm stuck here and I'm not sure what to do now to get it running again. I don't care about the data on my tablet at the moment.
Try plugging it into a PC USB port over night.

That's what I did that got it charged enough to get to try to boot, where it now shuts down. But now as it tries to boot it reboots, maybe from too much power consumption? I only had it plugged in for half hour or hour before that got it charged to the point where it boots to the logo screen. I have a feeling it is not charging because every reboot the light turns off (orange light stays on for like 5 seconds)
I will plug it in to my PC and charge it overnight and let you know what happens. It's interesting, I plug it in now and the orange charge light comes on, shows the Nook screen, then shows the low battery screen and shuts off, then the orange light turns off, but it remains plugged in... not sure if it is still charging but as I said, I will leave it overnight and see what that gets me.
No success. I can turn it on and the charging lights turns on for 5 seconds and shows the nook screen, then goes black and shows the low battery screen, then immediately shuts off and the charging light turns off and it no longer charges.
Any other suggestions? I can't seem to do anything with the Nook now.
I have a Nook HD+ 9 inch tablet (BNTV600) that I haven't used in a year. I finally found the charging cord I had misplaced and tried to charge it, but the indicator light on the bottom flashes green, then orange, then a continuous blinking red, and will not power on. I've tried charging from my computer USB port, as well as the Nook charger that came with it, as well as a friend's charger (her nook works fine so I know its not her charger) and it still does the green/orange/flashing red, but not turning on.
The last time I used my Nook it worked perfectly, so I'm at a loss as to why it would not work if it was just sitting on my bookshelf for a year.
Any help/suggestions appreciated! I'd love to get this working again
Try pressing the power button + and n button at same time and hold for about 30 seconds, if that dont work, you might need a new battery, I Had to replace my battery got it from EBAY, My BN NookHD+ is working very good, I have Android 7.1.2 in it.
I had a similar problem. The charging indicator was flashing red. Powering off and then on again resulted in the indicator flashing orange and green for about 10 seconds then back to red. I tried all the methods suggested from various websites . All to no avail. Before finally giving up, I remembered that way back I had revived a battery by putting it in the freezer before trying to charge it. So I put the nook in a sealed plastic bag and popped it in the
freezer for an hour or so, took it out and and connected it to the charging cable. The orange light came on and stayed on. The Nook was obviously charging and when the software eventually loaded (after about 2 hours) the battery had charged to 5%. It then took a further 10 hours to charge to 100%. The battery has been discharging at the normal rate depending on use. From a low level (about 10%) it is taking about 4 hours to charge to 100%.
I have no idea if freezing the device was the real reason and solution to the problem but it worked for me.
I bought my Nook HD+ in 2013 and it has been a great companion all along. About two years ago, I noticed that the battery was not what it used to be, requiring charging too often. Last year, I installed LineageOS on the Nook.
About three months ago, something happened to the battery so that the Nook would turn on and be usable only if the main power was connected. If I switched off the charger, the Nook would immediately shut down - and by shut down I mean it would just blink off, not shut down over a few seconds. Also, in the shut off mode, it would lose battery a lot, like 20 to 30 percent in a day, without any usage.
Then, about a month back, I forgot to charge it for three straight days and now it won't turn on at all. When I connect the charger, the charging light turns from green to red, and stays there, indicating the battery is charging, and the back of the Nook also becomes hot, but whatever I do, it doesn't turn on. When I press the power button, the screen comes on and shows the charging icon for a second or two and then goes off. I've left it charging for a couple of hours, maybe six or eight or so, but it still won't turn on.
If I remove the battery and turn on the main power, the charging light keeps blinking green and red over and over. So, is there any way to use the Nook without the battery, running it off the mains power only? And if there isn't, is there any way to turn it back on? I've already gone through the threads here and tried some of the things but nothing has worked. I don't have a higher power wall charger, and it is not possible to go out in the present condition, what with the lockdown and all.
Please help.
Hi
I also have a Nook HD+ that I'm still playing with

I also installed lineage on mine a year or two back, but I've had random issues with mine. I'm going to try to reset and reinstall it in the near future (like, maybe this weekend or next).

I know that, if the tablet runs dead, you _have_ to put it on the original Nook wall charger and let it sit overnight... mine just went dead a couple of days ago and I tried just plugging the cable into a generic USB charger, but it didn't charge. I then remembered this and plugged it into the Nook charger and it charged overnight.
If I remove the battery and turn on the main power, the charging light keeps blinking green and red over and over. So, is there any way to use the Nook without the battery, running it off the mains power only? And if there isn't, is there any way to turn it back on?

I have no idea about this part... I've never taken mine apart (I wanted to buy a replacement battery a few years ago but they ran out and I never found more). Update: I just searched and there are a few battery replacements listed with Google search, I just don't want to pay 40.00 to 50.00 when I can buy a new tablet for a little more than that.
I usually just leave mine plugged into my bedside clock and it keeps charged, or if I unplug it plug it back in within a couple of hours.
Hope you find an answer.
better off buying a new tab
