Yesterday my HD+ suddenly notified that it was down to 5% battery. I plugged it in and it instantly went to 33%. I left it charging for several hours. Came back and it was still orange but I disconnected the charger anyway. When I turned it on, it said it was at 100%. I used it for awhile and noted it was still at 100. Plugged it in, and it quickly went from orange to green and said "charged". This has persisted thru several reboots, including my usual CM 10.2 SD card, my CM 10.1 on EMMC and my stock SD card. Today I'll likely try to get stock back onto EMMC to ensure I'm covered if it dies. Anyone else had their HD+ get stuck at 100% or have suggestions on how to fix?

After completing a nandoid backup via CMW and restarting, it was clear that battery time was updating again, it was reporting 69%. But I went ahead and restored stock and flashed stock recovery in case I continue to have issues.

Not sure if i have the same issue. My Battery goes up to 100% while using the device unplugged on 10.1.3 and stays at 100%.
If the battery is drained (still showing 100%) i get the charging leds flashing red and i have to disassemble the device and re plug the Battery to get it charging again.
I tried some battery calibration tool from the play store. no help.

@Sherip: Faulty battery. Mine had a similar issue. Get it replaced ASAP.

Been running cm7 for a few months now with no problems. Battery was full when I left my house, came home and it wasn't turned on. Tried for a while and got no response. Plugged in the charger and it keeps restarting after the cm7 logo screen. The farthest it got was the home screen for about 2 seconds before restarting. I noticed the battery was in the red zone before it restarted even though it was full earlier that day. The battery usually last 3-4 days unplugged......
Have you tried to get it into cwm? If you can, download cm7 rom again on your computer and put on sd card and flash the from again, the rom could have been corrupt due to a bad download

My guess is it SOD'd, and the battery is dead. I have noticed that my NC will not power up if the battery is very low, even if it is plugged in.
I guess we won't know any more until the OP returns, but often when a charged nook just shows a dead screen, and it is actually on, and you just can't tell. There are multiple workarounds for this, but the easiest to my mind being a sdcard with a burned with a bookable image like CWM or a hard reset. Let us know after you have let the nook charge. If thencord is lot and it still won't turn on, try a bootable card.
Hi,
I just got my Nook HD+ yesterday and installed CM10.1.3 (stable) right away. Great job guys, the OS is really running nice and smooth!
However I've got an annoying problem (2 to be precise):
The Nook won't charge from the charger and the LED stays green. When rebooting with the charger plugged in it goes orange, but turns green as soon as the Cyanoboot Logo shows.
The only way I can recharge the Nook is via my PC (although painfully slow, had I not found verygreen's Charger Control tool).
This leads right to problem 2: The Nook is not recognized by the PC at all via USB. On some of my ports it shows up as an unkown device, but there seems to be no traffic between the two (PID and VID of 0x0000).
Both problem could not be solved by updating to CM10.2 M1 or wiping caches or data.
Any ideas on this?
Thanks!
€:I just tried reinstalling the stock im (from my cwm backup) to see if it works in there. Result: nope, same thing. Charging from the PC, but not from the wall, no USB connection. However after connecting to my wifi and reporting available updates the Nook suddenly rebootet only to get suck at a Cynaoboot screen followed by a flickering TWRP logo. Which is rather strange since I thought I had just installed a full backup thus removing both of those.. So I am guessing there is still some stuff gone wrong left on the device. Installed 10.2 M1 again afterwards.
So how can I make sure that I get back to a truly clean state on all boot-related partitions without having USB/ADB access? Which can be wiped from CWM or TWRP without risking a brick?
€€: Oh well.. I just set up a bootable sdcard with verygreen's 10.2 binaries on it and started the Nook from that.. Same behavior So it seems like either my hardware is bad (which would suck since I'm in Germany and shipping it to the US and back would cost more than the Nook did) or there is some serious weirdness going on...
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?
I'm getting constant times when my nook HD+ just shuts down, it first happened in cm11 the 9/11 nightly, it would shut off when I went on certain web pages and on YouTube, then it would shut off when I tried to change the wallpaper. It would then shut off at the cm boot logo after about 2 seconds,only being able to boot fully after repeating about 4 times. So I did a factory reset and reinstalled the rom, but then when I tried to install gapps the device would shut off, so I went in did factory reset again and formatted system, installed the ROM and gapps fine this time but the first time it still shut off at the cm boot logo, its now booted back into cm 11 the second time but still getting shut off's when I try to apply wallpaper etc.
I've re installed the stock ROM and I'm still getting random shut downs and its saying my battery is 1% when its fully charged
can anybody help please ?
same here

i have been having this issue for like two months now. it all started when my daughter ran the tablet out totaly. took a good three days of tinkering before it would actualy take a charge. now i get constant shut downs, flickering screen. will say im 100 percent charge and when take the cable out it will go down to 1% i dont think the battery is bad because sometimes it will actualy hold the charge.
Could be the power connector or at least somewhere along the power path. My old kindle had what looked like battery issues which was actually the cable itself at the port that was a bit loose and a different cable had fixed it - it even said it was fully charged but drained 4x faster (give or take). After the fix the battery life was normal again.
Its would be incredibly confusing [to me] if draining all life from the battery is the cause of your problems as I do it often with all phones/tablets (and others do it) and its never caused me a problem not even once. I do it on purpose not accidental.
More likely a coincidence and not the actual cause and the issue is that something was damaged or going bad. It doesn't sound like a software problem. And since it appears to be battery related that would likely be the battery or related path such as the power cable, port, wall plug.
Since its made by humans, I'm going to say if it turns green fully charged then its not necessarily anywhere near fully charged especially if the incoming power wasn't the proper amount, it could potentially be thrown off and confused instead of what one would expect happening that of either/or.
Wrong or right there's my best guess. Do with it what you will.
Adding if its still under warranty (I would assume), according to leapinlar, BN will give you a new power cable if that's the problem, or same with the device (as I took advantage of for hardware defect).

They will only give you a new cable if it is still in the warranty period AND it still is running stock. You may get by with just taking the cable in, and if they can demonstrate it is defective, get a new one. But if you bring the device in with CM on it the warranty goes bye-bye. So if you take it in, be sure stock is on it.

*gasp* the rest of it. Thanks for the correction there.
GOT IT
So i took it apart thinking i would replace the battery. Didn't end up having to. i disconnected the battery from the main board, then plugged it back in. tablet fired up and showed 100% battery. haven't had a single issue since. :good::good::good:
(Please see post #4 as the issue has evolved)
I recently updated my husband's HD from CM 11 to CM 12.1 (the one build in @amaces obsolete folder). This restored some functionality to a few apps that had "moved on" beyond KitKat and preserved the HMDI functionality. Everything else is essentially the same. Except.
Too often on starting the tablet up in the morning it shows about the same battery level as at shutdown the prior evening (maybe 50-ish) and then in a matter of minutes nosedives to 1%. You can see the behavior on the power usage graphic in Settings and it's pretty shocking. There's a vertical line for when it booted up and then *bam*, it drops to essentially nothing. If the tablet is plugged in for just a moment, the battery level returns to normal and everything is fine. It can be disconnected from the power supply and behaves normally the rest of the day.
So this is annoying (moreso because I need to hear about it every time it happens ). I've read the entire (unofficial) CM 12 thread. This issue comes up once or twice and seems to be "resolved" by "calibrating" the battery either with an app from the PlayStore or without. The app seems to just delete a file that would be overwritten at boot anyway from what else I have read on the subject, but the main idea is to drain the battery to an actual 1%, shut down and charge (the tablet remains "off" although the screen is on) until you've got 100% (which has to be judged by the green LED since the tablet is off).
I tried this (with the app), beginning by wiping cache and dalvik cache. It seemed to work for awhile. Then I foolishly suggested doing a backup. I did this with the emmc TWRP and everything seemed to go well except the battery indicator issue started up again...
So we did the battery thing again.... And it was just fine until this morning (not what you want to hear as you sit down to breakfast).
Clearly one could live with this if you always have the charger close at hand, but it's pretty lame. The tablet behaves beautifully in all other respects. I don't think it's a hardware issue as it started right after flashing the new ROM.
One person in the CM 12 thread actually praised the ROM as eliminating this issue which he had from CM 11!
Is this a flashing glitch which might be fixed by reflashing the ROM? I'm loath to do a clean install and reconstruct everything again after such a short time, but I wonder if a "dirty" install (don't wipe data, right?) would be enough. If I reflash the ROM do I have to reflash GApps also?
Suggestions? I'm really at a loss here.

I doubt if a dirty flash would change anything, but there does not appear to be any penalty to try it out as a shot in the dark.

Not if you don't wipe /data -- basically same as in the case of a dirty upgrade.

I finally got around to this after much complaining about the issue and now I've managed to make it much worse. Before, the tablet would drop from the 50's (or lower) to 1% on boot. Higher percentages of charge were usually safe. Now it goes through the boot process up to the animation and then abruptly shuts down UNLESS the power cable is connected, regardless of the state of battery charge. If the cable is connected boot occurs normally and you can disconnect after boot is complete and everything is "fine".
Except, of course, it's not "fine" at all. Unless you have the charger and cable with you at all times, the tablet has to be left on when you're on the go.
Ugh. Any ideas besides going back to stock and starting over?

I came across a post that suggested returning all the way to stock and doing a factory reset, then rebuilding the system.
Once at stock I had no trouble completing a boot without being plugged in. So that is not a hardware issue. I didn't stay on stock long enough to see if the battery indicator behaved, but I'm guessing it did. I prepared a completely new SD card with newly downloaded files and proceeded to do the needed flashing for CM 12.1 w/GApps, using CWM 6.045. It all seemed to go well--even no screen flashing--until I unplugged the tablet so I could easily remove the SD card and reboot. As soon as I removed the power cord the periodic screen flashing that seems to be common during CWM use started up.
I rebooted and got only so far with the CM logo before the tablet shut down.
I don't get it. It worked fine before. What about this process could be causing this odd behavior?
Edit: in desperation I tried flashing The ROM again right over the prior installation. This time I booted into the emmc CWM (6.0.4.6) and waited for the tablet to calm down. Then I unplugged it and flashed the ROM from the ext.SD card. No error messages. I held my breath and rebooted. I got to several iterations of the cyan android face and then it shut down again.
Next I flashed TWRP 2.8.7.4 to emmc and tried flashing the ROM from the ext.SD card that way. Same result.
The battery charge shows 80% so it's not like the tablet is running on fumes and it's hard to believe the problem is the battery or the indicator since none of this happens on the stock ROM.
I just don't get it. We don't want to go back to stock but I don't understand any of what is going on. Initially CM 12.1 was working beautifully. Then the battery indicator issue started. I addressed that as best I could and when it seemed like we had that on the run I did a backup. That resulted in this shutdown issue. You can use the tablet just fine if you never turn it off and keep either the charger or a portable power pack handy (don't forget the cable!).
I really need some help troubleshooting. I'm willing to try just about anything.
Edit: indeed, the last resort was to buy another HD... But it turns out the booting issue was caused by an SD card that somehow was not properly prepared as 0x0C FAT32 LBA but was instead something else which I don't remember now (something with a "b"). Anyway, once a new card was carefully prepared, the tablet booted fine without being plugged in. Whether this also solves the battery indicator issue remains to be seen.
