Here's a weird one.
I plugged my NC in to charge this morning. It was just fine and then all of a sudden, the green light turned off and now the NC is no longer charging even though the battery is only at 59% .
What gives? Anyone else notice this?

Have not experienced anything like that. If I did though, I would reboot and see if that changes anything.
Good luck.
Try a reboot. I have noticed the last couple of days that my NC charges, but the status on the battery is not updated until a reboot. I have not figured out why this is happening yet. . .
I will try. The thing is, when i connect to the laptop via usb, it no longer recognizes my device as a drive. My macbook says it's drawing too much power and disbles the port. I'm wondering if they're related? I guess the NC charger requires more juice .......

I have two Win7 laptops and one of them no longer recognizes my NC as a drive either. The other one sees it as the Nook Color and as two drives. It's strange. I have not tried to find out why yet as there are only so many issues I can worry about at one time.
You know. . . I have noticed my problem just in thelast three days, and I have not tried it on a USB port in that time. Let us know if a full restart fixes your problem. It does sound a little different from mine.
I had the same problem till I started doing the following:
Make sure Nook is completely powered off.
Plug in USB cable, Nook boots up on it's on.
Turn off WIFI.
Unplug USB from Nook and then plug USB cable back in.
Now: Nook charges correctly in CHARGE mode:
It seems it takes unplugging 2X to get it into charge mode. You will see the light turn amber on the cable and the status of the Nook will be charging. The battery icon will show as well.
Well, that's annoying. Will i have to do that every time?

So rebooted the NC last night and plugged it in to charge. The light was orange and device showed it was charging when i went to bed. I just got up and the light is no longer on and battery only charged to 90% overnight. What gives? Is there somthing faulty?

And i just rebooted again and the NC still not recognizing the charger.

Yet another update --- I finally got the NC to start charging again. Now the light on the cable turned green and the battery is only at 97%. Isn't it supposed to stay orange until the battery is fully charged?
Never had any problem charging mine at all... I plug it in typically towards the end of the second day, or when it gets much below 40%.. I always (intentionally) charge it using the Nook Charger and Nook Cable, any other combo will only charge it slowly, probably around 10%/hr at most IF the NC is standby/screen off.
As for how far it charges until it says it's done... Some Android phones stop showing "charging" at 90% but continue to slowly charge to 100%, some it's higher... And when it hits full it TURNS OFF THE CHARGER until it drops below the threshold again. This is how charging LiIon is done. I personally haven't paid any attention to how the NC charges, as it "just works" for me.
I'm wondering if it's something wrong either with my cable or my actual NC. Ugh. I don't want to return for another unit.
Bump. Anyone else seeing these charging issues? Should I take this back?

Not sure how relevant it is, but "slow charging" will not charge device very quickly, buti does supplement battery life quite nicely. since open wifi is my only internet source atm, I use an fm tranmitter with a usb port to listen to pandora in my car without draining battery at all. actually slowly charges if screen is off.
I'm just trying to figure out if there is something wrong with my NC or it's charger.

Dunno, but I finally broke down and bought a NC yesterday morning.
Had a b!tch of a time inserting the mini-USB cable, which presumably should not be the case. Managed to get it charged. Mine came OOB w/a 98% charge!
Then stupidly I removed the cable, but wanted to sideload a book shortly afterwards via Calibre and again had a b!tch of a time getting the mini-USB cable inserted. (Only mini-USB device that I have, so no other cable to compare with.)
Can't even get it to insert this morning, so I'm giving up for now and back this one goes.
Not real impressed so far with the build quality of a $250 device. Arguably OOB both the Pandigital Novel and Augen Gentouch were better. To make matters worse it doesn't even come close to the gTab's build quality either, which I was expecting it to be closer to.
Funny note in the manual that I noticed while browsing through it(checking to see if they maybe had a sneaky trick/lock to insert/remove mini-USB), and found a line:
"do NOT turn off NC while charging"?!
I usually turn off my devices while charging as they'll charge a bit more quickly, typically...

I would suggest that rather than relying on the battery percentages, start looking at the actual mV readings of the Spare Parts/Battery Information. I say this because I've seen android have fits trying to give accurate battery percentage readings. I'll put mine on the wall charger now and post the max mV level I can reach. Perhaps others can as well?
Ok I just put my NC on charge and the battery was reading 13% and showing a 3601mV reading.
My replacement NC, whose USB/charge cable inserts MUCH more easily that #1's did, came OOB @ 98% too, but #2 took FOREVER to charge to green... touch screen on this one is supersensitive as well... now to check for dead pixels, hot pixels, and chipped screen...
Getting tired of going to B&N, and their CS wasn't exactly wonderful as they were going to try telling me that #1's cable/USB port were fine and dandy until I made him check that the LED wasn't coming on & that the demo unit inserted more readily and further into the socket, just like #2 did which I checked right at the register but didn't linger to check for dead pixels, etc. as I was holding up the checkout line(@ 9a?!).
I went to look at one a few weeks ago too at that same store, and the woman at the Nook kiosk wasn't very interested selling. (She'd rather continue reading her NC than trying to sell one.)
#2 also came upside down in the box, i.e. the tab on the protective plastic to pull out the NC was at the end that doesn't open...
B&N needs some serious QA/CS/sales training... esp. with their crap return policy... well 13d to shake down and see if anything else falls off...
is there a way to "not" have my NC turn on when it is off...and i plug it in to the charger? i dont like having to plug it in first, then turn it off when i want to charge it and not use it.

To my knowledge, it has yet to be discovered. Which definitely irks me.
If you have it rooted, NEVER let it get low on battery. Recovery from a semi-brick in my case took 1.5 days since I had to do a crap load of charging since it was bootlooping and sucking juice.
Someone will find the setting and share hopefully.

It will turn the screen off at the normal amount of time, so what's the issue? You mean you want the NC powered completely off? Why bother?
Isn't this likely a hardware/firmware trigger?
If you read your manual.... B&N says to *NOT* turn off the NC while charging.
I don't think it is possible to charge with it off. In the 1.0.1 zip there was a charging file that looks like when you plug in the charger it has to use that code to charge properly. I haven't seen something like this before but it could be possible. If so, no charging ifvthe nook is off

So I just found this:
http://forum.xda-developers.com/showthread.php?p=12513699#post12513699
and a modified version for my HTC Aria phone. It works great!
Is there any chance a dev here can modify CWM for eMMC to work in this way?
Pretty sure the Nook doesn't need any HTC hacks to charge while off.
isn't it an issue with the cm7 builds not being able to go into deep sleep (or having that option turned of or something?) cuz it causes problems with wifi?
i thought the not turning off if plugged in issue was related to this

Not sure if you were trying to be a smart-ass or not, but obviously my Nook isn't made by HTC, however if I plug it in while it's turned off, guess what, it turns on.
I believe it's a Clockwork "hack", not an HTC specific hack, but I could be wrong.

That is because it is actually supposed to turn on when you plug it in. You should have it plugged in and then shut off to have it charge while off. No need for a HTC clockwork mod, as the problem was only with HTC devices.
I know you can turn it off after it starts charging, but it's not supposed to turn on, as you say, the stock Nook doesn't.

Yes it does. Plugging in any nook while off turns it on.
Really? Guess I missed that in the day or so that I had an unmodified Nook.
Still would like to hear from a dev whether or not the system could be modified to not fully boot when connected. It seem illogical to me to have a device as power-hungry as the Nook boot up when you want to charge it, which will slow down the charging process.

Day of stock? Pft 10 minutes.
But yes, it does seem completely bass-ackwards to have it do that.
Isn't this driven by the whole USB then microSD then EMMC boat loader? It makes sense to me that the device be turned on when plugging in USB if your first boot device is USB.
Ahhh... didn't realize that the Nook had USB booting, that would probably kill this. I thought it was just SD, then eMMC. Bummer.

It's not wifi it's the touchscreen and other parts go too far into sleep and will never recover. This has nothing to do with charging or recovery.

It's a hack implemented by Clockwork to replicate the same behavior that the stock HTC recovery does on your phones.
Before this hack was in place plugging in your HTC Aria while off would force it to boot into recovery with no real reason. This modification just boots into a "off-mode charging" screen which was implemented using the recovery ramdisk and kernel but a different userspace program.
The Nook doesn't need this as it's implemented in hardware quite well.
1) The nook will turn on automatically.
2) There is not enough power the bootloader will display a screen needing more of a charge
3) It seems, based on my testing, that the nook will continue to charge even when the device is full turned off.
So in conclusionL I am glad it worked for you on your HTC Aria, but this hack is for specific HTC phones and does not apply to the nook color.

From the B&N Nook Color User Guide:
To charge your NOOKcolor from a wall outlet, do this:
1. Assemble the power adapter and microUSB cable. Insert the large end of the USB cable into the matching receptacle on the power adapter.
2. Plug the NOOKcolor end of the USB cable into your NOOKcolor.
3. Plug the power adapter into a compatible electrical outlet. If your NOOKcolor was turned off, it will now turn itself on.
NOTE: Depending on how much power remains in the battery, it might take around 3-4 hours to fully recharge
your NOOKcolor. Do not turn of your NOOKcolor while it is charging.
NOTE: Once your NOOKcolor has enough power to turn on, you can see how much power remains in the
battery by checking the battery charge indicator in the right corner of the Status Bar. You may need to
drag the green NOOK symbol to the right across your screen to unlock your NOOKcolor and display
the Status Bar, which runs along the bottom of the screen.
4. Once your NOOKcolor has fully charged, unplug the power adapter from the electrical outlet. Unplug the USB
cable from your NOOKcolor.

Seems like there is a design reason for that.
What? You can boot off USB too? I didn't even know that!
sorry, i was totally off i guess, thanks for the clarifications guys.
I've powered my NC off after i've plugged it in and have come back to an already booted device.
This is not once or twice, it's pretty much all the time.
Maybe i just have a weird device? I DID buy it off craigslist used... but i've had no issues at all as far as user functionality goes in the month or so i've had it.

I knew that, but was trying to avoid that step.
Thanks for all the info guys, I still think since the Nook does charge after powering off, it would be nice if someone could find a way to skip that whole boot/power-down process so I can just plug it in and walk away.

Are you running the stock ROM? Mine did the same thing until I installed a different ROM. HC and CM7 both stay off when charging after I have powered them down.
I've been running CM7 nightly builds off emmc mostly, if not the tablet tweak ones before they were integrated.
Not something I consider an issue for me, but I've yet to do any complete wipe since I first flashed CM7. I might try phiremod over the weekend unless the fascinate forum blows up with new stuff (our 2.2 source code finally dropped today), in which case I'll do a complete wipe and see if the problem persists.
EDIT: Yes, i'm running with the latest OC kernel
EDIT 2: Ok... I didn't notice before, but I guess I have a sort of faulty usb? not sure but it flickers from time to time, like on and off. I've never really paid attention to it while it charges, but i just noticed that the light on the N went off and came back on a few seconds later and confirmed that it flickers from time to time on its own. So on the bright side i guess i don't have hardware with an anomaly, too bad I have a charging cable with a mind of its own
Are you running one of Dalingrin's Overclock Kernels? I'm guessing not, since that would be the only other difference.

I've been plugging it in and then powering it off to charge. Now I find out that the guide specifically states to not turn off your NOOKcolor while it is charging.
Will charging while it's powered off screw up the battery calibration?
edit: one thing I've noticed is that if charging powered off, the usb light never turns green when it becomes fully charged.
Using the newest build of verygreen's emmc 10.1 CM.
Every so often I'll plug the HD+ into the stock charger and cable, and the light will turn amber for about 2-3 minutes, then it will turn green. It will say "not charging" instead of "discharging", but it won't gain in charge and will very slowly discharge.
The only fix is a reboot.
Any other similar experiences? Kind of annoying, since I'll let it charge overnight only to come back to a nearly-dead tablet.
Thanks.

Mine only charges when Usbhost is off.
I'm running a July rom of verygreen and for the first time since running it my hd+ would not charge
when plugged in.
I normally leave it sleeping with wifi off.
I plugged in charger and it would not say it was charging.
did a reboot and then it charged itself.
I am using the latest version of verygreen's cm 10.1 before it went official and have no problems charging with us host off.
Happened to me once. Hard rebooted and the issue never appeared again
Last night I let my HD+ discharge to 1% for the first time. (It was interesting. It reported 5%, then jumped up to 7%, ran for about 15 minutes, then suddenly announced 1%.)
I immediately turned it off and put it on the charger.
I usually don't let it get below 15%. Fortunately I dodged a bullet in that it started charging when I plugged it into the OEM charger. (I read later in the forum that sometimes you can't get the HD+ out of deep discharge.)
BUT . . . the charging behavior has changed. I can't charge the HD+ up anymore when it's off. It has to be on now to charge.
IIRC, it used to be that I could plug the HD+ into the charger when the HD+ was off, the yellow light would come on, and the unit would charge. It doesn't do that anymore since the deep discharge.
I came back into the room about 15 minutes after starting the charge and I noticed the back light on the HD+ was on. The unit had mysteriosly turned itself on and booted when I plugged the charger in.
So I turned it off while the charger was still plugged in. The yellow light went off and when I came back in an hour, the unit had not charged at all.
In the end, I had to disconnect/connect the charger and let the unit boot to charge it up.
Doesn't seem right that the unit should do an un-commanded power on. Not sure if that's a bug or supposed to be a "feature." (Like, to tell the B&N warranty team that you let the battery go deep?) I can't imagine how this could be a ROM issue - the power button is a "soft-switch" which is controlled by hardware or firmware. But I cleared /cache and /dalvik anyway. (No change.)
Anyone else got this behavior? I read one post in the forum where a guy had to open the unit and unplug the battery to get a "reset" just to get it to take a charge. I'm hoping I don't have to open the case.
So, maybe I don't recall correctly?
I found a post over in the cyanogenmod forum where someone claims the Nook HD+ needs to be on to charge.
So maybe I'm all confused. Maybe my HD+ always turned on when I charged it and I never noticed.
Can someone confirm for me if their HD+ will charge powered off?
Thanks.

I'm pretty sure the stock HD+ works that way but I don't know if that's a hardware thing or a B&N software thing. I usually just plug ours (we have both HD and HD+) when they get down to 25% or so and they rarely get turned off.

Well, it's easy enough to power it down to see if yours will charge powered off.
I was fairly sure I was able to charge power off, since I woulda thought it was odd that I couldn't. And I thought I had done that at nights, powering it down for the night but charging it up at the same time to get ready for the next day.
But again, it could have always been that I just never noticed the unit had booted itself on. Then I would have assumed I had powered it on when I got back to it.
Anyway, I await some soul to power theirs down while plugged in and report if theirs charges powered off.
