Charging issue?

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...

[Q] nook charger colors meanings

Hi,
I Just noticed That when I plug it into my computer the nook charger has an orange/Yellow LED color, but when I plug it into another computer it has a green color - without any relation to how much battery he has.
At first I thought that orange means charging and green means full But apparently that's not true.
Thanks.
P.S
-- I wouldn't have even bothered asking this if it weren't for this rule:

EDIT:
Figured out the problem, the other computer slow usb ports were just not fast enough to chrage it, so the nook charger lighted green

Today, for the first time, I noticed my Nook Color USB power cable had an illuminated red colored "n". And that was while the cable was unplugged from the Nook Color itself. (But, obviously, while plugged into the wall charger.)
I thought to unplug the charger from the AC wall power. It takes several seconds for the LED to stop glowing. I waited about 15 seconds after the light was not visible before I plugged the charger back into the AC socket. The cable glowed red again.
Upon plugging the cable into the Nook Color, the cable shows orange again. (As I'd expect, since it's been a couple of days since I last charged my Nook.) The battery icon on the top status bar is "filling", so I think it's actually charging.
I'm used to seeing a green "n" when the battery is full. And orange/amber/yellow when charging. Until today I have not seen a red "n" at all.
[Later, the same day... .]
I -do- find the battery is fully charging. I just have this funny feeling that I ought not leave this thing alone in the house, or take a nap, or whatever, charging. Somehow I think I'll end up on the nightly news... another "victim" of Lithium-Ion gone horribly wrong. ;-) I'll probably try, like some others I've now found via Google, to get B&N to replace the cord or charger.

Wonder if this has something to do with the poor quality of the charger? There is a thread about the chargers breaking easily and the plug bending and eventually breaking.
Just a thought...

I love both my Nooks (they serve different purposes) but the chargers/cables are very problematic. I had a perfectly working one with my first purchase but an accident destroyed the usb connector and B&N sent me a replacement. It worked for a couple of days and then died a slow death. I ordered a second Nook and got its cable confused with the third cable sent to replace the second defective one. Both worked fine, though, for a couple of days and then suddenly the N on one turned red while plugged in to the Nook or even connected to the computer. Tried it on two other Nooks and the same thing happened. So, I'll be calling in for my fourth replacement cable. I am very glad that I paid for the warranty; it has more than paid for itself with the replacement chargers/cables that B&N has sent to me.
On a side note, when I was waiting for the replacement cable and had no other Nook charging cable available, I used my Blackberry microusb charger to trickle charge the Nook. It literally took all night but at least it was up and running the next morning. It doesn't charge fast enough to use while running apps, as the battery discharges faster than the BB charger can charge the battery.
Again, I love my Nook, even with the charger/cable issues!

I'm running Froyo off the SD. Every since I've done that, I noticed that power cord never turns green when charging is finished at 100%. Has anyone else run into this problem as well?

Faulty LED on charger

So, I thought I see if anyone else has had this issue with the Nook charger. My first charger stopped lighting up correctly (not turning green when charged). The LED actually never changes from amber, even when the nook is not plugged in. It also stays dimly lit for about 60-120s after the cable is unplugged from the wall. It still provides the normal charge, but I'm scared to use it. I had this replaced (and the replacement is now broken - arg), but I was wondering if it might be safe to use.

Weird Nook HD Indicator image (flashing red indicator light)

So, I love my Nooks. I have an HD+ and an HD, and I've had a Nook Color or two in the past. I recently gave my Nook HD to my daughter in favor of my HD+. She brought it to me today and told me that it will no longer charge or power on. We know it's not the charger cable as I have used all three of the OEM chargers that we have on my HD+ with absolutely no issues at all. When I plug the HD into the charger, the battery indicator light turns from a flashing green to orange into a constant flashing red light. If I hold down the power button and release after 20 seconds, I get an image that looks like a triangle warning image with a red full thermometer inside of it. Above the triangle there are red "steam" squigglies as if to indicate that the unit is overheating, however, it's not hot at all and has in fact been off for over three hours. She told me yesterday that when she plugs it in, sometimes it doesn't recognize the charge at all. The battery indicator will show 13-15% and discharging until she unplugs and plugs the charger back in at which point it would show the actual current charge. Can't get anyone to help me out on the B&N website so I thought that I would come here. Her Nook is completely stock, unrooted and we are the first and only owners. Anyone out there have any idea as to what the heck is going on, or should I just take it back to B&N? (About a week after it came out of the box, she dropped it while it was inside it's case and ended up chipping off a part of the plastic shell, not sure if they will even touch it with that problem)
I am handy with electronics when it comes to replacing components but crap with the software... If they won't take it I feel comfortable in replacing any parts that need replacing by myself. I would rather not because it is only about 4 months old. It is also very VERY heavily used. She's always got that thing in her face. Any help would be greatly appreciated.

Sounds like a hardware failure. I would try to take it back, chip and all. If they won't replace it, I would consider buying a new one while they are on sale.

ook dead blinking yellow red wont charge [FIXED]
My Nook HD+ had been running great and was loaded with CM 10.1 for 09/01/2013. I had been on eleven day without a charge and finally widdled it down to 1% battery. This was with light usage of course. My nook powered off and from that point would not take a charge. I tried various hard reboot with the plug inserted and would get a brief battery icon with thunderbolt and then yellow and green flashing of the charging indicator light. It would often turn to red blinking as well. I let it charge for several days, tried different cables, and even tried to slow charge it from PC. I had read somewhere that sometimes when a battery got too low on some devices they would not charge. I decided to take my nook hd+ apart and attempt to hard wire the battery for a charge to a fabricated wall plug and wire cutters. Well it turns out that I didn't have to get that far. Just unplugging the battery cable from the motherboard somehow reset the battery and it started to finally power on. I immediately plug the charger back in and let it get a good charge before I put all the screws back in. The tear down process was very easy and I just followed a youtube video to do it. If anyone is in this situation, I would give this a try as it only took about 10 minutes and a small torx screwdriver.

My nook hd+ won't charge and blinks read I already changed the battery and tryed a different charger it still won't work

How long too recharge HD nook if battery completely dead, bought new charger flashing red

Nook HD+ - Not charging Not Powering On

Hi,
I seem to have a peculiar problem with my brother's Nook HD+. When I plug it into the wall charger, the device shows a green light, which turns orange and the Nook powers on to show the Nook logo, but all of a sudden it switches off and the light disappears too.
I have tried holding down the power button while the device is plugged in, holding the n and power button down, using another charger, but nothing seems to work.
How can I troubleshoot this?
Any help would be much appreciated.

Let it in charge for 1 hour. (orange light) then remove it. Wait like 10 minutes and try to turn it on. Press the power button for 10 seconds. Repeatedly

I'd suggest leave it plugged in and charged with the BN wall-charger for 4-6 hours.

The device is not charging, the orange light does not glow.
Here is what happens after plugging it into the charger - the light turns green for 2 seconds, then orange, the screen comes alive with the nook logo and then all of a sudden, the screen wipes out blank and the charging light also switches off.
I've tried to put it on charge the whole night, tried to turn on the device, hard reset - nothing worked.

Had a very similar issue with mine when I first got it. Turned out it was my USB cable, I called Barnes and Noble and they sent me a free replacement.

I've tried using two different USB cables. The other one is from my other Nook HD+, both the cables seem to be working fine on the other Nook.

I have the exact same issue with my nook right now. It has cm 10.1 installed. But my screen isn't even flashing on at all. It just charges green for 2 seconds, charges orange for 2 seconds, then goes black. Won't turn on. I've had it charges for like 2 days with no luck. Have you figured out what was wrong with your nook yet? I'm going to get a new cord this weekend I guess. Can't think of anything else to try.

I had the same issue of not powering up. Plug it in get the green ,then yellow, then nothing. tried everything. Well almost everything. My last effort got it going. plugged it into a PC at that point it went green , then yellow, but this time stayed on yellow after about 40 minutes it booted.. I was elated.Hope this helps:laugh:

Thanks! Went to a B&N today and got a new cord. Plugged my nook into the charger at their display booth and it showed the charging screen and the LED stayed orange. I was stoked, so I assumed the cord was broken and I bought a new one. Tried it at home, and same #%^#ing problem: green for 2 seconds, orange for 2 seconds, and then off. No screen boot up or battery charging display. Last resort, plugged it into my computer, and it is keeping the orange LED on (yay), but still hasn't booted. It's been a couple of hours, so hopefully it boots here soon. I'm gonna keep it charging with my computer overnight and see if that fixes the problem. Then (if it ever boots), I'm going to put a new OS on the thing so hopefully I don't have to fuss around with the issue anymore. Thanks Ifearnogod. I also fearnogod.

Had the same problem with the Grandson's, pressed and held numerous button combinations no luck so sent it back to argos for a complete swap out replacement. Guess what after a couple of days the replacement unit did the same thing. Now i'm tearing my hair out after looking through various forums with no answer i tried the daughters Galaxy note charger and bingo it worked, it appears that the original charger supplied with the nook HD plus is not powerful enough to do the job from a completely discharged state. I've told him not to allow it to go completely discharged and we haven't had a problem since with the nook supplied charger.

I have the same prob
I have the same problem, but with my Nook HD (not HD+). I used a different adapter at one point because I lost my Nook adapter. This may have caused the problem for me.

I've got a Nook HD that's acting like this, if I plug it into my computer or into the original charger it blinks green orange green orange, but never powers on. I've held the power button until it starts flashing orange only but it never charges it. When it's connected to the PC it keeps popping up a usb device failed to install prompt so I am thinking that this means the cable is working. I bought a replacement battery to put in it. Hoping that fixes the issue.
I did try it with another usb charger and it changed it's behavior slightly. It would flash green orange then show the N logo then shut off. If I left it on this usb charging adapter it still never would charge it up.
That is why I'm suspecting that it's a bad battery.
I'll get another charging cable next if that doesn't work.

I would go with testing a new cable / wall plug before anything else - but then for the price I would probably just jump on it then chuck it before spending money on a proprietary cable for an aging device.

Aging device? I would try to get a new cable/charger under warranty. Stores will do that if you can show the old one defective.

Its aging to me. Its been out for a long time now. I would go with something newer [then spend money on it] - but that's subjective - so I'm not getting into any debate here.
So they do that with just the cable - that's cool stuff.
lol.

yeah the battery didn't fix the issue. It's still not charging, if I connect the charging cable and adapter while it is turned off it turns it on, flashes green orange a couple of times then goes solid green. It boots up but I'm running on the remaining charge in the replacement battery I put in. visual inspection of the charging jack on the nook HD doesn't show any issues, visual inspection of the cable also doesn't show any issues. I'm going to take it to the closest barnes and noble and hope that they are willing to give me a new charging cable today. I guess we will see. Hopefully a new charging cord will fix the issue.

Make sure you still have stock on it if taking the device to the store. Alternate ROMs void the warranty. Maybe you can just take your charger and cable along with your serial number if the device is not stock. They can test to see if it charges their devices.

great...
my nook HD have booted on. when i plug it in a DELL's laptop. the light was green -> orange -> and still orange, after few minutes it boot on and install 148update :laugh::good::laugh::good::laugh::good:

The battery not charging and tablet appearing dead other than the led is a common problem with tablets, not just the nook.
In the tablet they use a chip that has a controller integrated to charge lithium ion batteries. The controller has limits that have to fall into a preset range or the controller will not allow charging. If the battery voltage is low enough , the controller will experience a spike in current when the power is connected, that will trigger an excessive current limit in the controller which blocks it from charging the battery. The cycle repeats over and over and it will not charge because it is never on long enough to get the battery voltage higher.
The fix is easy on most tablets including the nook. You have to open up the case , will void warranty, unplug the internal battery and then connect that battery to an external charger for about 20 minutes to get the battery voltage up high enough to stop the over limit from occurring. I have about 6 tablets of various models that wouldn't turn on or charge and all were fixed and working great by doing the above. Actually a way to get tablets cheap if you see some with the same symptoms.
On the nook the wires you need to connect to charge on the battery are any red for + and any black for - . There are I think 3 red and 3 black bunched together on the connector, any one will work. After charging re-attach the battery and it should boot right up. Just be careful about letting the nook get below about 10% charge.
The charger you use can be just about any standard charger that can charge 7 volt lithium cells, the nook has them wired in series , 2 batteries x 3.7 ~ 7.4V.
A good cheap one that takes out having to worry about charger settings is :
TLP-2000-Tenergy-Universal-Charger-3-7V-14-8V

Here's my story:
Rooted, running CM11 no problems. Read some comics, decided to download and try out Dragon Age from the play store. I had ~35% battery remaining (hard to tell exactly, circular battery mod). After the game downloaded from the store, I opened the app and it began to download the larger files the game requires. I sat the Nook down while it was downloading and eventually the screen turned off/timed out. I tapped the power button to see where the download was and it would not turn on.
So, as of now, pushing the buttons in any combination for any amount of time does nothing. Plugging the tablet into the wall gives me a green light only (never orange). Holding the power button (and any button in combo) for ~10 seconds kills the green light. Pressing the button again lights the green light. I've left the tablet on the charger for over eight hours, two different times now, no change.
Plugging the tablet into the PC acts the same as above, however the PC also repeatedly gives USB device connect/disconnect warnings (sounds) for a bit.
WTF, any advice?
