Is there any way to get the NC to charge off the USB port hooked to a PC and not the wall charger ?? Is it possible at all ?
amen to that. Its stoopid that you cant use a microusb for charging. I only have 50 of em. I know the vable is special but they should have made it a different design to not lead us on!
My NC charges just fine with a standard micro USB cable connected to either a wall charger or PC.
It displays "Not charging" but it does in fact charge.... however, it takes a lot longer than with the provided cable and wall-charger.
The socket on the NC has connectors for both standard USB and their proprietary stuff.
Correct me if I'm wrong but I think this is the same saga that iPad users went through. The device requires 2 amps to charge correctly, but a standard usb port only offers 500 milliamps or 1/4 of the required dosage. So while I havent tested it myself, it sounds feasible that the nook is charging, however its nowhere near the required amperage to show the charging icon on the device.
It sure does take a long time on a computer. Over night isn't enough. Even my Ipad charger takes for ever on the NC.
Charges just fine
Mine charges just fine, as long as I use the nook cable that came with it. I plugged it in to the PC this morning and it was only about 70% charged. I don't know how long it took, but when I grabbed it a few moments ago, the n was green and it was fully charged.
Mine charges from ~30% to 100% in about 3 hrs, via USB to a computer. I always make sure I use task killer to kill most processes before charging. It makes a huge difference.
after root I have been able to charge from usb. btw, despite the message below, this reply is sent from my NC via xda app.

Been charging it from USB since day 1. As luck would have it, I forgot the wall plug at my friend's parents house, some 80 miles away... I was spending thanksgiving there when I got the NC. So yes, charging works from the computer, but as they said, it's slower. Not really a big deal though, I do this crazy thing at night called sleeping, during which I dont have much use for the NC, so it sits next to my bed, charging off of the laptop. And the cool thing is that it'll continue to charge even after my laptop goes into sleep mode.

the NC only has a 1530mah battery, which should not require 2A to charge. my samsung captivate has a 1500mah battery, and charges fine from USB. the NC should be able to charge from USB fine, but it's strange that it only does so very slowly.
I thought the NC had a 4,000mah battery

i saw a replacement nookcolor battery at best buy that said 1530mah, but on nookdevs it does say 4000mah. weird. nooksdevs is probably right. best buy probably mislabeled that battery i saw.

You probably saw a replacement original nook battery. If you saw some of the teardown photos (mine), it's pretty obvious that this battery isn't user-replaceable. Ok, maybe my pictures aren't the best, but take my word for it. That block outlined in black in the fourth photo is the battery and is bigger than your entire captivate
A "Y" shaped USB cable with two male type "A" connectors that is plugged into two USB ports may charge the NC while avoiding the "Not Charging" message. However, since the overcharging / monitoring circuitry is external to the unit it may not be wise. It very well could decrease the lifespan of the battery and without the ability to easily replace it, I wouldn't try it myself.
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...
Ok so this nook was bought brand new in December 2010 For my mother In-law. She hasn't used it much. So I asked if I could put Android on it? She said sure cause she hasn't used it at all. As a matter of fact the NC was totally dead when she gave it to me. So I get back to my house and put it on the stock charger. I let it charge for 2 hours. I picked it up and turn it on and all I see is this message: Battery too low to power ON. I did a search and turned up similar problems but the nc where all rooted. I'm wondering if other people have had this same problem? And what they did to solve this as it is more then likely an easy fix. A. Take it back to the store and exchange it. Or. B. Send it off for repairs. C. Someone On XDA has the answer.
Also I've done some trouble shooting like trying to reset it. Also I've used 3 Other chargers and its still not charging or turning on.
Edit: It turns on it just stays at the screen with a red battery displaying the message in the title. Also after charging for a while the screen kind of lites up like its going to turn on but only goes black after that and then comes back to the same red battery screen.

what are you charging from? are you using the stock nook cable and plug?
Yes. And charging it from the wall outlet. Did that with the stock charger. my charger from my HD2 and also tried with the charger from my vibrant. All have the same affect. It has the red battery and the messege below and it also has been a total of 6 hours of charging 2 hours each with the all the chargers.
That stinks. You may have to contact B&N for it. If your using the stock and other chargers then it must be a battery failure.

Yeah seems to me thats what it must be I'll post back what I find out.
When that message is displayed, try holding the power button for 30+ seconds and then turning it back on.
That has worked for me the couple of times it seemed stuck on that screen.

If you're using other chargers, it's possible that you've damages the usb port. The NC uses a non standard usb port, which has two stages. The first stage is standard 5 pin uusb communication, the second stage is non-standard 12 pin charging...

Non-Standard chargers...
As far as I can tell it works fine with any microusb cord.
Their charger cables break...(bend and break) very easy. I have gone through 2.
The upside is that their charger provides power far faster than the normal microusb cords.
At this point...I'm charging mine almost exclusively from my stock evo cord.
If you don't turn off the screen when charging...it may not have enough power coming in to actually build a charge without their cable.

I never used another charger besides the stock charger that came with the NC. Up until this happened all that was ever used was the stock cable for charging. I only used another charging cable once I ran into these problems cause I figured the cable was damaged. Its happened to me before with other devices. But the same results happen with every cord I use. When I plug it in it lights up and shows the red battery screen. So that tells me that the cord or USB port couldn't be the problem. Cause its clearly getting power its just not charging.

No. They sell it without one...the 8GB internal storage is enough for looooottts of books. The microsd was just a nice + for people with lots and lots of music.
I had this issue as well, but I found a fix!
No matter what I did or how long I let it charge, it would always have that red low battery icon.
What I ended up doing to fix it was opening up the back of the unit and disconnecting the battery cable from the unit. I then plugged it directly into the wall without the battery connected to see if it would boot, though I don't know if that was necessary, I don't even remember if it booted that way or not.. I think it did not.
Anyway I unplugged the power cable again, reconnected the battery, then plugged in the power cable and tried to boot and it booted up perfectly after that. The battery icon indicated 13% charge, but it quickly charged back up just fine.
FYI I left the unit in the car overnight right before this happened, and it was pretty chilly that night, 10-20 degreed Fahrenheit. I suspect that caused the issue for some reason, so I've been sure not to do so since.
P.S. I had to do a fair amount of googling around before I found good instructions on taking apart the NC. I think I had to take off the 2 screws under the SD card slot and use a butter knife to just pry the back off. It's just held in with clips and you can't tell it was opened except for the little stickers over the screw holes.

Thanks for the feed back. I'm wondering by un-pluging the battery from the nook if it resets it. Kind of like if a phone freezes or if your computer freezes and you pull the battery. Seems like a plan. Not sure if this is what I'll do as I'm sure its still under warranty. If it comes back and its not covered or B & N wont replace it I guess thats my only hope.
im having the same problem as well it was off for a while and now its at the red batter screen. i guess ill try and take it apart?

I had this problem too, but I'm not sure "faulty" is the right word for the cable.
My friend borrowed my nook and returned it with a dead battery (Thanks asshole). So I plugged it into my computer at work and just got the always-on low battery message. After 45 minutes I took it to my car so I wouldn't forget it. I plugged it into my USB charger in the car using a different cable. Two hours later, same state.
When I got home I pugged it into the Nook wall charger with yet another cable (not the nook's original) and got the same thing. I searched here to see if I could figure out what was going on and decided to try the original cable with the wall plug. literally two seconds after plugging it in it started booting into Froyo.
I'm sure I didn't have four "faulty" cables. I think those that are saying you should be using the original are correct. The others worked fine when the battery wasn't empty, but mine only responded to the original once it got to the point of the unending low-battery message.
Original charger / cable required with totally empty battery
Same here. With battery completely empty and non standard cable,stuck at red battery sign forever. With orginal cable, boots fine and charges.
solution I found
Have CM7 installed on SDCard, got the battery icon, even with the unit plugged into the charger with oem equipment. Held the power button 'til the unit turned off completely, removed the sdcard, rebooted. Nook booted into stock fine, turned off, re-inserted sdcard and rebooted. All is well.
It's not normal for a nook to charge 10% -> 60% in 6 hours, correct?
Has anybody experienced the same issue?
I installed Honeycomb right after getting nook -> then i did nookie color ->
First I noticed it on Ultimate Droid FW, so I than I flashed to CW7 latest nighty with OC'd kernel, and now i am back to nookie froyo. and the issue still exists.
I haven't found any tools that do battery/power tests..
I was just charging nook for an hour, without using it.
went from 19% to 26%.
I think its quite low.
Thanks
i find the wall charger charges insanely fast. the usb charging is the one that is snails pace for me.
maybe try wiping your battery stats in CWM?
when you say "from a wall charger"
Do you mean the one included with the NookColor? or a different one?
With froyo on emmc, and HC on microSD, I find re-charging via the included 1.9A charger pretty good. Charging from a 1a cell phone charger is slow. And charging via USB port on PC, doesn't happen.
Wall charger -- the NookColor 1.9A charger.

Are you pairing that with the original Nook Micro usb cable? or are you using a different usb cable?
The cable that came with the nook as 2 extra pins that allow for the fast charging. standard usb cables wont have this.
If you are using the original cable and the original block. I would say that they are defective,
I have never heard of a Rom or Kernel effecting the charge rate like that but you might try going back to stock and see if its the same results.
*O and it should only take 3 hours from 0% -> 100% with the Nook cable and Block that came with the Nook Color."
Alright, thanks. I'll try the stock rom.
Can I exchange nook color in the store for this problem? or there's a procedure for that?
Cheers
Yeah I'd definitely say it should only take 2-3 hours to get a full charge from empty. 6 hours is way too long with the nook charger, that sounds more like the time it would take with a standard usb port charging it.

Depends on when you bought it. If it's still in the right time frame, you can just exchange it in-store. If not I'd recommend looking thru the website and/or calling about it instead of going in-store since they probably know more.
I think doing the wiping battery stats in CWM did the trick.. its charging quite fast now.
Thanks everybody for your help!
i had been running into this.. and could figure it out... i will try wiping bat stats too and see how it goes... thanks for the tip!
I rooted my Nook about 2 1/2 weeks ago running CM7 encore nightly 146; had no issues with the battery whatsoever. All of a sudden no matter what USB cable I use whether its the B&N cable/charger or not, the battery is taking forever to charge. Like this morning at 800am, I used the B&N cable/charger for the Nook and the battery reading as of 12:04am (Thursday) is still only at 61%. I mean come 17 hours to charge a battery and it's still not a 100%!!!
I wiped the battery stats in recovery mode and rebooted it hoping that it would incease the charge but no such luck. FYI, everytime I charged my nook the screen would always stay on and I use it pretty frequently to watch movies, read books, and use the web browser.
As of now, I powered down my nook to see if it would charge without being in sleep mode to see if that was the prob.
I really would appreciate if anyone could help me with my problem! It's very frustrating!
It will charge much faster if you attach the charging cable and then power off the Nook (however mine sometimes will turn back on during this process).
That's a pretty old nightly!
It will only fast charge with the B&N Cable AND B&N Charger. Any other combo will not fast charge, and will charge only at 500mAh vs 1900mAh.
Unless your NC is very loaded, it will charge quite fast on the fast charger, so I suspect you're not charging it with the cable + charger or there is something wrong with one of the two.
