Charge off USB possible ??

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.

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...

micro usb cable

I am using the Nook color wall charger, but left my cable at work. my nook was dead, i plugged in using a standard micro usb and the wall charger, it says wait 15 minutes, which makes me believe it is charging it. Let me go check...still says that. Do you think it will charge? I was able to transfer files with the micro usb cable to my SD card on the nook, but it wont charge it?

It may trickle charge on a non-OEM Nook Color cable (a standard micro-USB), so it would probably require charging overnight at the very least to get a near full charge once again, and certainly longer than 15 mins to get it back to usable from a low charge state.

Depends on the output of the charger, but youd likely be looking at anywhere from 4 to 8 gours for a full charge...

i think i can confirm standard micro usb does not charge this thing, even with the nook wall charger. I had it plugged in from being dead for about an hour and it never came on. Thankfully i found the real charger and am back in business.

It will trickle charge for me with the nook cable hooked up to my computer, but I thought this issue was already covered and others said it would charge with a regular usb cable (again on the computer not via the adapter). Is this not the case? I hate to think I'm reliant on the nook's usb cable and can't charge at a friends.

I have charged my NC with the cable from a cell phone. It takes a LOT longer and in fact, doesn't seem to keep up with even moderate use: wifi and web browsing and battery will slowly continue to go down. Just not AS slowly as being unplugged.
But it does charge.

Hopefully someone will find a way to make the damn thing charge without verifying that it's using a Nook cable.

False, it does charge. I assume at .5A, but it's possible it's lower. Haven't looked.

Plug it into any USB source using any cable providing 500mA, it will charge. It won't SHOW it is charging, as it doesn't appear to show charging unless it's on the fast 1.9Ah speed the Nook charger + special Nook cable provides. However, if it's idle enough the thing does charge.
Sitting on my desk playing with adb one day plugged into my workstation it charged 20% in a little over 2 hours. Of course that's pretty slow, but consider this is a 4.0Ah battery, you cannot compare to your phone charge times unless you multiply by 2.5 to 3!
So 20% over 2 hours would be 50-60% over 2 hours on a typical Android phone battery.

you say it charges, but leaving it plugged in from being dead to the Nook wall charger but to a standard USB did not charge it at all. No power
I have no doubt that the nook cable, plugged into a PC will charge it. It is the cable that is different.

Here are the ways that I have verified that my Nook Color wil charge:
NC wall charger/NC usb cable- best and fastest
NC wall charger/Droid usb cable (standard) - charges slowly
other USB wall charger/either usb cable- charges slowly
computer USB/NC usb cable- charges slowly
computer USB/other usb cable- charges slowly
What I have NOT done is completely drain the battery and test.
My guess is this: it charges slowly without a high rating charger and the special NC cable and when it is dead it takes a LONG time to get enough juice to boot.
Another possibility is that device variance has kicked in and while most people seem to get at least a trickle charge out of any cable/charge source we have, other units simply will not.

that is kind of what i was thinking, the fact that it was dead was not enough to even charge it properly where as if it had kind of been charged then maybe it would be more noticable that it was charging.

It charges no matter what cable or charger as long as it's providing reasonable current. Most USB ports and non-fast chargers provide 500mAh.
If it's dead I don't know, I don't do that to LiIon batteries.

[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

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?

Can not bump energy into Nook

Hi,
after having problems with running out of battery:
http://forum.xda-developers.com/showthread.php?p=19807551#post19807551
I can now hardly get any energy in the Nook. I used the original power cord and when i plug the cable in, the Nook Color recognizes this and poweres up. The display shows a Battery sign (i booted in the stock ROM) but it dont seems to be normal. Sometimes the LED of the cord flickers green and sometimes it stays orange. Sometimes the Battery symbol goes away and pops up in a second - it seems as is there a defective contact. At the moment i have plugged in the cord and the LED stays orange. But the display says: Not charching. When i power off the Nook it stays off with the cord plugged in (which is also not normal - normally it boots again).
I tried also two other USB cords but the display says: not charging.
Sometimes (i think when it flickers) it bumps some energy into the battery which is 51% at the moment.
Do you have any hint or trick for me?

You may have a bad cord. You can power down the Nook after it is plugged in and it should stay powered off. If it restarts you have a short somewhere. Does the cable fit snugly in the port? You can't use another cord. If still under warranty ask B&N for a new cord. If not, they are $14.95 from B&N.

I've bought it in the US and iam living in germany. Can't exchange the cord on warranty

Just use another USB cable then. It will be slow but it will charge. Otherwise you can buy another adapter from b and n as stated

You cannot use another cord unless you want to completely shut down the Nook and wait over 24 hours for it to charge. The Nook cable has a 2 step pin configuration and you will not get the needed power to charge it properly. B&N ships internationally.

Pat... the only way the nook stays powered down with charger connected is if you select power off from the power menu... if you jus hold the power button it will reboot...
You can use a standard uUSB cable without taking so long to recharge if you shut the screen off after the charger is connected.

I know that Den. That is how I always charge mine. From what I have read from other users using a different cable, even when completely powered down it takes forever to fully charge. Someone else suggested using a higher capacity charger but I think that is just asking for trouble trying to force more current through less pins.

Regular micro usb cable plugged into AC will yield 1000mah charge rate, more than enough for the Nook to charge even with the screen on. I plug mine into my laptop for overnight charges (USB power yields 500mah charge rate) and the screen has to be off for it to charge. ~12 hours for it charge from <5% to full this way. Half that if you're plugged into a wall (also with the screen off).
The proprietary cable has an additional pin that lets it charge at a rate of 1900mah.
So yes, a regular micro usb cable works fine. In fact I only use the B&N cable if I'm in a hurry (due to their tendacy to break).

Weird, cause I charge it every day without it being shut down. Even with the screen on (but with the backlight off) it still charges. If the battery is dead I plug it in and one hour later the device turns on with 10% power. I then have to turn off the screen because it will stay at 10 forever until I do that which is weird cause the rest of the time I have it in that state it will charge. So yeah another USB cable is workable

I stand corrected..........

Hi,
i tend to say its a hardware problem. The LED of the Nook cord flickers sometimes. As i said before, Nook color tells me, it wont charge although the cord is plugged in.
The best i can do is remove my SD card where CM7 resides and boot into stock and charge from there. Although the LED flickers it charges - slowly, but it charges.
When i use another charger (with another cord) it wont charge at all. Furthermore i lost overnight again 80% of battery (booted in CM). I dont know why.
Just a further remark: Although i used the Nook cord i have connected it to a HTC Desire charger since the Nook charger dont matches to german electric network. Nevertheless i used this configuration several months and had no problems at all.
One stated that BN ships international. May i also send my Nook back to BN and do i have warranty? My Nook was bought in may.

That might be more problematic. The Nook Color is not available outside of the US. If you have a US address and credit card attached to your B&N account you may be able to have a purchased cable shipped. Trying to get a warranty claim shipped outside of the US may not be in the cards.
