Got an NC for Christmas and after reading all the awesome help on here got it rooted and set up the way I wanted it. So I plug it in night before last and it wont charge. Had to hold it at a certain angle then when I let go it would quit. I call B&N and they were gonna send me a cable. I said no the port is bad and I tried another usb cable and got the same result. So they are sending me another NC should be here tomorrow. I had barely 20% battery when I restored it to stock (which they told me to do before sending it back) or I would have been screwed. Anyone else had his problem? Also she told at first that another USB cable wouldn't work on it?? Anyone else use another cable or phone charger?
Thanks again for all the great info on here!!
All I know is that the mini-usb port on my NC -- where the charging cable plugs in -- is a mess. I have to insert the plug at a sharp angle and wiggle/force it, before it will go all the way into the port. (lame!)
On another note, the black plastic around the larger USB plug at the other end of the cable fell apart completely on the second day I had the NC. That end of the cable is now being held together by electrical tape. (even more lame!)
I'm considering an RMA for the entire unit to try my luck with a new one...
PS: performance wise, once rooted, this thing kicks total ass for $250!
Yeah, once mine is plugged in if I push the cable around it will stop charging.
I wonder if that Tear down gave us a reason for this?
After reading lots of posts over the past months it seems the port/plug is the most often reported problem .. I have two units and one (the first) is just fine, the other had difficulty with plug insertion but once inserted was fine. I tried the plug from #2 on #1 and yup, it was a problem to insert, so perhaps the B&N supplied cable is the problematic part, not the NC itself?
Saw that the EU has/will 'standardize' on the uUSB for charging .. personally don't understand ... it can't make that much difference in design/mfg and the miniUSB is very much more preferable to me .. sturdier it seems ... but it is what it is and I still love my NC!!!!

NC #1 that I got last Thursday had a fault USB port, as in I had a b!tch of a time getting the USB cable inserted, but managed it twice on Thursday for initial charge and a second time to try something sideloaded from Calibre. (Actually was about to return it as soon as I got it home and had trouble with the cable insertion until just as I was about to give up and pack it up, the cable went in...)
The next morning no amount of fiddling would allow me to insert the cable, so I factory reset and went back to the B&N for a horrid cs experience before they finally deigned to replace it. NC #2 the cable inserts MUCH more readily into...
Crossing fingers that nothing else goes wrong with #2. Ended up giving up on a pushed 1.01 update and sideloaded it last night, but first try was a phail, 2nd try went as expected. They need a user fw check and initiate fw update app as their OTA doesn't seem to be very robust or even work AFAICT.

Sounds like the charging port is a piece of crap. Still love the NC but I dread everytime I have to plug it in to charge it. Also when I plug it in to the computer or the wall the screen goes crazy and is virtually unusable. Read a few cases on here but no real explanation as to why.
As far as the update. Had to sideload it on both of the NC's i have had. Never would push it to it. Strange.
My first NC had a bad charging port. I returned it immediately. The second is fine.

Does your screen act up when plugged in? Mine does either plugged in the wall or the computer. Just curious how many people have this issue??
I haven't returned mine. The cable that comes with it is difficult to insert, but if I fiddle with it, it goes in. I have a generic cable that I use to connect it to my PC and it charges it, too. It may be slower and doesn't indicate that it is charging, but if I leave it plugged in all night, it is fully charged in the morning.

You do realize the NC (and most phones) uses MicroUSB, right? And actually MicroUSB is rated for more insertions and is sturdier.
The reason the NC's cable is a PITA is because it's not a standard MicroUSB, it has extra pins on each side to deliver the 1.9A of current that the NC charges at.

Great info. What I was wondering about. One question....will it hurt the NC port to use a standard micro usb cable to charge or connect to the computer?? I did on my first one and thought that may have been the reason it went bad.

I would not think so, in fact if that were the case I'd hope B&N would have had the jack not fit normal MicroUSB cables, but who knows.
Also B&N knows users aren't going to unplug the cable from their charger and plug it into their computer.. At least a reasonable number of users won't do this, although I might be the exception having a MiniUSB and MicroUSB dangling out from under my monitor for plugging in stuff
I've plugged mine into my computer numerous times, no problems so far. It does charge from any USB source, albeit slow.
On the new one. No.

Yep. #2 has that problem while #1 did not. I notice it on #2 as soon as I had gotten home and had it charging and was trying to do the setup/registration... It was an exercise in frustration...
I'm going to be letting #2 discharge today, then do a full charge and carefully track how much time I get off the charge since I've read a battery runtime thread on the B&N forums. (Very low backlight & WiFi off.) Might need to return #2 for battery problems as it seems very short to me although I have not been keeping careful track of how long I've been running between charges...

It is very frustrating! Guess will just have to quit using while charging. About the battery, are these like the new phones where you can just charge them each night? I do this on my Droid X just wondering if it would hurt these batteries?

I have this problem. I believe this is caused by the AC adapter. I went to my local B&N and hooked up my nook to their charger and had no problems. I called B&N support and explained the problem to them. They said they would send me a new AC adapter which should have arrived yesterday. It hasn't arrived yet but I think that should fix the problem.
I also have a problem with having to insert the micro usb in at a funny angle, but once in it charges.

Think I will call them as well. Just to calm my OCD.
Yeah I have insert my USB at an angle as well. Once there though it is fine.
Would like to know about the battery though as I stated in a post above.
My sister bought one on Monday with a bad port. She took it back and got a new one.
BTW - My sister so liked my rooted Nook she went and bought one. She came straight to my house to have me root and install apps.
Hi guys, I accidentally left my charger and USB cable at a friend's house 700 miles away during a visit. She sent it back to me, but it's been a bit over two weeks and I'm tired of being Nookless, especially with all of the new stuff developing (cyanogen on the way? AWWW YEAH!!).
Neither of the two BN stores near my house have replacement charger/cables in stock and it appears that the BN website does not either (not even a price listed, just a pic/description).
What is the cheapest way for me to get some power in this thing? I wouldn't mind charging solely through USB. Is the stock NookColor USB cable any different than a normal micro-usb cable? Can I just order a normal $2 cable from amazon and expect it to charge?
The cable that comes with the NookColor differs from a standard micro usb in a couple of important ways: It has extra pins to deliver a higher charge. OK, I guess by "a couple" I meant "one that I am aware of." Alright, maybe one more: The charger itself is rated at .5A, which is higher than the standard plug for usb chargers.
You might be able to trickle charge from a standard usb. I was able to get some power, but not much.
Here's one more thing to do:
Ask the manager at B&N if she has any extra chargers and cables in the back. Here's why I say this: I had to return my cable yesterday because it wasn't making proper contact with the pins and thus was not properly charging. The manager told me that he has a heap of NookColor plugs and cables in a box because when they send units back to wherever they send them for repair or reconditioning, they are instructed to send only the Nook, and not the cables.
It's worth a try.
Good luck.
It does charge very slowly when connected to the PC...It will charge overnight if not in use..
I have some Nokia cables (from my mobile) with Micro-USB, they are loading the Nook nearly as fast as the original one. Very handy for charging in the car.
I have been charging my nook with only a standard cable since day one. My nook came with a bad cable and at the time was one of the last nooks in my area. I have been calling B&N almost weekly for over a month and they keep saying they will send me a cable but I have not received it yet. I have had no problems charging my Nook overnight. I even emptied the battery once and it still charged fully over night.
A regular microUSB cable will eventually charge the NC, if it's sleeping. No 3-hour quick-charging, though.
Does the slow charging really have to do with the cable?
On high draw devices (e.g. iPhone or Palm Pre) the charger shorts the data pins to signal the capacity for higher current draw. The cable has nothing to do with it.
I have noticed the Nook plug is longer than a standard micro USB plug, but that only means you can't use the Nook cable on another device's micro USB port.
Anybody know the potential problems trying to root with a non-standard Cable?

Is this confirmed to be true? If so, what allows a non-Nook USB cable to be used with the Nook?
I'm sure the cable itself is different, either by using the data lines as additional power lines for higher current capacity, or perhaps by adding some resistors to pull the data lines to certain voltages so that the Nook can identify when the "right" cable is connected, so that fast-charging can be enabled. I just can't quite grasp the idea that the cable is not physically compatible with other micro-USB devices.
I am able to use the original nook usb cable, my samsung moment usb cable, and others for data purposes, no issues
I have two other devices that also use M-USB for data transfer, and they work just fine.
I picked up a few of these a while back and they work as well:

It seems that you can call B&N support for a new one if you had issues with your original. Not the OP's problem, but Some have had the issue.

So the idea is that these could be used only for data and trickle-charging? Even if it's connecting the Nook to its official power-thingy (is there a name for those?)

I am just using it for data transfer and charging with the stock wall unit. As far s using these cables or other USB devices that using the MicroUSB interface would require some type of software driver (USB Host) in order to make that work. As far as I know at least.

Actually... .5A is the minimum for all plain jane USB ports.
If I remember right, when I flipped the charger over when I first got the NC, it is rated at 1.9A, which would make sense considering the size of the battery we are charging and at the speed we are charging it at. Hell, my Epic uses a 1A charger and it is only 1500mAh battery vs the NC's 4000 mAh.

True but.... I have been calling for well over a month and first they could not ship me one because I bought it at Best Buy and they did not have the warranty info yet from Best Buy. I finally got past that and since the week after Christmas they have been shipping me one each time I call. I have yet to receive one. I am going on 2 months now trying to get the cable shipped to me.

I don't think there are any.. I do all my ADB work using a "non-standard cable". The usb cable that came with my nook wont let ADB work right. When I type ADB devices with my factory cable I get the serial number but instead of device it shows suspended or something like that.

Here is a link for a Hi - Power USB Car Charger. It's 2100mA and can run and charge an Android Tablet or iPad at the same time. Also the microUSB cable they offer, shows "Charging ( AC) ” When plugged into my Captivate. Most just showed "Charging ( USB) ".
Sent from my Samsung Captivate with Perception 10.3, Firebird2 v0.8 #77 Kernel, Firmware 2.2.1, Modem T959TLJL3 using XDA App
.5A is nothing. Most phone chargers now are rated at 1A with ones for tablets going above 2 as someone else mentioned. Most BT headset chargers are rated at .2-.5A in comparison. Some GPS units have charges rated over 1.5A. My Dash unit had a 2A.
And if I'm not mistaken, if you're connected to a computer you will only get a tricklish charge as it's limited to .2 or .25A (I believe).
In regards to actual cables, any microUSB cable will work. I've used stock ones from Samsung and Palm phones as well as cheap 50 cent ones from Meritline. And if the Nook one is actually longer? Why wouldn' it work in something else? The cable will just stick out further.

I tried posting a day or two ago about this, but wasn't able to get any replies or any help at all actually : /
Anyways, for some reason ever since I rooted my nook, when i plug a charging cable into it, it either
(a) Pulls out of sleep mode and shows the Lock Screen, which drains the batt
or
(b) Will actually turn the device ON and do the above stuff, making it really hard to charge in general
Is there any way to fix this? Right now my nook keeps hovering below the charging line and reboot looping, then when it does have enough power to actually full boot, it drains itself faster than it can charge bc it runs the screen at full brightness.
HELP PLZ!?
Your charger must be bad or some other such problem, because that's what the Nook does: plug it into the charger and it boots itself up or comes out of sleep to the lock screen. It will blank the screen relatively soon after if it is running correctly.
On top of that, the charger supplies way more than enough juice to charge even under heavy use.
Are you using the nook charger and the nook cable?
Im using a MicroSD cable either through the computer or through an actual AC port in an adapter.
Im basically now at the point where I can't charge the thing enough to get it past the "Battery is Dead, wait 15 mins" mark. It sucks so hard :<
Im thinking I may have to take it back to Best Buy and try again, I have the warranty on it, just I really dont want to do that! >_>;
I am having the same problem......

Yes, it does make a difference. A standard USB cable and charger takes 8 hours or so to charge an NC. The B&N cable and charger that came with your NC can do it in 2. Use them.
yes, it seems to make a difference. I can only connect to the PC [mounting the drive] with the originally cable. With the generic cable, it will charge but doesn't seem to charge as fast [less than half the speed]. I would suggest you try to get your hand on a original and see if there is a difference for you also.
from the user manual:
CAUTION: Only use the Barnes & Noble power adapter and custom microUSB cable supplied with your NOOKcolor. Other power adapters might damage your NOOKcolor and its battery. Do not use a power adapter and cable intended for other models of NOOK eReader. Use only a NOOKcolor power adapter and cable.
NOTE: Using your NOOKcolor’s microUSB cable, you can connect your NOOKcolor to your personal computer to transfer files. Connecting over USB cable does not charge your NOOKcolor, however. To charge your NOOKcolor, you must plug it into a wall outlet
My USB cable is red now(the little N light on it). Before it would either be green or orange but now when the nook is not connected, it's on and red. Why? Anyone know? Is this a problem?
mine has been doing that too, but it still charging, so I didn't think any thing of it...

Mines charging as well but I figure a red light like that must mean something and I'm worried that the cable could be damaged and charging my battery incorrectly.
I emailed customer service at Barnes and noble to see what they say. apparently poll who don't root it who have asked on their forums have the same problem, but there was never any real solution/answer.
They replied with the following
We are sorry you are experiencing problems with the charger for your NOOK Color and we are eager to assist you.
If your NOOK Color is plugged in via USB to a computer, try plugging the cable into a different USB Port; a red light generally indicates "no connection." You may also want to try plugging your NOOK Color into the AC Adapter and charge it via a wall socket.
If your NOOK Color is plugged into the AC Adapter and is charging via the wall socket, make sure that the USB cable is connected properly and it is not loose on either end. If the light is still red, the cable may be defective.
We reviewed your email, and based on the information you provided, we feel that we may need to process a warranty claim for you. Before we can get started, we need to speak with you to verify certain information about your device, and to make doubly sure that we understand the problem.
We ask that you call us at 1-800-THE-BOOK (1-800-843-2665) and select option 2 for NOOK Support. We are available Monday through Friday from 8AM to 11PM EST, Saturdays and Sundays 9AM to 11PM EST. Customers outside of the United States may contact us at 201-559-3882.

based on their description, I think they are saying if it's plugged in to the charger and the nook and red, then it's bad. not if it's not plugged in...
Guess I will call them tomorrow and see if that is correct.
Mine spent the last couple of weeks failing in very weird ways, finally being dark, red, amber, or green depending on just how I held it. New cable fixed it up.
The really bizarre thing was that it kept the same "plugged in" state it had at boot time; if I plugged it in and booted, it thought it was plugged in forever, and if it was unplugged at boot, it never charged or thought it was plugged in at all. USB mounting didn't work no matter what state it was in.
I think that the software has more to do with charging than I thought.

Just got my nook, and my cable won't light up at all. When I turned off the room lights, I can see a very low orange dim. My unit won't even charged. I may have to buy a new cable. there were alot of bad comments on the B&N site about the defective cables.
I hate proprietary cables, and the fact that if it breaks, I'm SOL until I get a replacement.

Why buy one? Go to B&N with your cable, charger, and NC and you'll walk out with the appropriate component. Most likely the cable, but it's possible the charger is bad. There have been cases where they don't have any to hand out and they have to ship it, but either way you don't have to buy one.

It will charge and communicate via a standard USB cable, but it will of course take much larger to charge.
I got the 16GB Touchpad few days ago and since i got the one with an american charger i cant charge it yet (till i get the traveler kit).
My actual problem is that it doesn't charge through the USB port too. I left it for like 24-30 hours charging through the USB port (with the cable that came with the touchpad) and when i try to turn it on, it shows me an icon of an empty battery.
Is my usb cable problematic or it just that the touchpad cant charge through the usb port from a PC?
ps: every time i plug the usb it get a message telling "to reliably charge please use the charger and cable that came with this device"
I have the same issue with a 32 GB one. I received it brand new, factory sealed today and it is going back to HP. I called HP, the cable is fine, works with my HTC phone, it's the USB port on the Touchpad, it's loose and losses connection. HP is sending a box with prepaid shipping label and doing a warranty repair.
I really love the Touchpad and I am a bit disappointed with receiving a new device with a loose USB port. HP has great support and I can't wait until I get it back.

Unfortunately thats not an option for me (returning it to touchpad), since i bought it from Ebay (thats the only way possible for me to buy a touchpad from my country).
You had the same issue with the charger plugged in the usb cable as well?
What sort of power source do you use, if not the charger.
I've tried to use a computer, but it does not look like it's charging, but data transfer work.
I tried with an iphone charger, that sort of work. It complains about not getting enough power (iphone charger is 5,0V while the hp charger is 5,2V)
Bottom line. Use the original charger, just buy an us adapter. It works great.

Im trying to charge it through my PC using the original cable that was in the box (tried it in a USB 2.0 port) and im getting the 'try a reliable recharging source like the USB cable and the charger that came with your touchpad'.
I also tried charging it with a 5.0V 200mA phone charger but it didnt work either.
Shouldnt it charge even a bit with the cable? im trying to charge it for 2 days now

Unfortunately thats not an option for me (returning it to touchpad), since i bought it from Ebay (thats the only way possible for me to buy a touchpad from my country).
You had the same issue with the charger plugged in the usb cable as well?

Yes, tried the wall charger, then pc, a different usb cable, all had the same result. When I plugged in I could feel the USB port loose in the Touchpad itself, it had a bit of play and if I played gently on it, it would begin to charge or connect to the pc. When i let go, it disconnected from my pc and then gave me the charging error message. I purchased mine from an e bay store and it has a warranty for 1 year.
I would be happy to help you with yours, if you want to ship it to the US, it has a warranty from the factory. Pm me if you'd like help. I am certain that shipping to and.from US could be costly but I am willing to help.

Mine will only will charge from official HP chargers. This is much like my old iPhone 3g before all the generic manufacturers caught up. I suspect that the voltage and amp requirements are tighter than the USB specification, so it will be a crap shoot if you use non HP chargers.
With that said, HP has 30% off all touchpad accessories right now. Combine it with the cupon SAVE15HP

Don't worry over that, I can get what you need and ship it to you.
Also, in speaking to HP, any USB charger in the US works, they're considered universal.

you cant charge the touchpad using a computers usb ports. it doesnt draw enough power. the voltage of the charger doesnt really matter, it needs at least 2 amps or it wont charge the touchpad. cell phone chargers usually only draw 1 amp or less and usb ports only .5 amps.

That is absolutely not the case.
I have only charged mine once with the AC-USB thing and I have been using it since I got it the first day of the sale. I use mine all day long and only charge it occasionally via USB to PC connection. I use the original cable from HP and another one from my Samsung Mythic (work and home).
The message that you get when you plug it in is misleading but normal on a stock TP. However there is a patch in PreWare that changes it to just default to charge and not bug you. Anyone who intends to use this thing at all with WebOS needs to get PreWare installed. In fact, some time spent at precentral.net would benefit any new owners. You will learn A LOT more about these little jewels. I spent a few hours reading stickies and interesting threads and learned a great deal.
If it is really plugged in (and you will know because your PC will tell you) and you get no charge, you have a problem. It should charge on or off while plugged in - mine does.

The problem is, its plugged, i get the warning but its not charging at all (while the touchpad is turned out cause its out of battery the past 2 days).

Now to be completely honest - the first charge I made out of the box was with the AC adapter and I left it in overnight like I had been told.
But since then I have never used the AC plug and I have let it get down to about 20% or so but no lower.
It very well may be that from a DEAD state, it requires the extra amps to jump start it, but as long as you have that initial charge it is covered by the lower amperage of the direct USB-to-PC connection. I'm guessing it came with a fair charge and you burned through it without ever plugging it in to the USB.
Bear in mind that not ALL USB ports on a PC are powered the same either. Older USB 1.0 and 1.1 are crap for power. Front or top-mount ones also may not have as much juice as the ones in the back directly off the motherboard. Look at portable hard drives, some come with a double-header cable to use two low-powered ports. I know my top-mount ones will not power my 1TB 2.5-inch drive, but the ones in the back do.
However, I am really surprised you can't pick up a standard plug in USB adapter for your country for a few dollars (equivalent) for wall. Jeez they sell them at the dollar stores here now. I don't know if a car adapter would output enough to do it but that is another idea. If you can get one, you should be able to bring it back easily enough. The 2 amp adapter does charge a lot faster.

LOL, I am really in a rare mood as this question has bugged me a little. So I decided to find some straight poop. Here is the best description I have seen anywhere.
http://www.maxim-ic.com/app-notes/index.mvp/id/3241
If you don't want to read it, the gist (as I understand it) is:
At 5V, the USB ports in a PC have to be able to source (provide) at least 500 mA (.5 AMP). However, depending on how your motherboard is provisioned (MOSFETs and diodes) that is limited/controlled.
The spec though, does allow as much as 5A to be provided. In fact, 2A is not uncommon if the other ports are not loaded.
So you could try unplugging all your other USB stuff or try another computer's USB ports.

Given that the HP charger has a 2A output, odds are that anything much below around 500mA isn't going to charge the device, or at least not at a rate that'll offset the drain while it's running.
The USB ports on laptops often won't supply enough current, particularly if there's other devices on the same bus. If you plug it into a powered USB hub then you should be in business as they should supply more like around 1A generally.
My Touchpad charges from my laptop USB port, however it is slow. I am getting about 8 - 10% charge per hour. The screen needs to be off though, otherwise there is no noticable charging happening.
Mine is not charging with USB laptop at all. Need to use wall charger
I have XRON VB2.8 on my two touchpads and both show battery charging symbol when they are connected to computer via USB and yes the they charge very slow.
FYI, can't remember if WebOS / Govnah tells you what the current amps being used is, but if you are on Android tools like Elixir 2 tell you how many amps you are either discharging (-) or charging (+). So depending on what you are using (wifi, bluetooth, # of widgets, running applications, screen brightness, overclocking, underclocking, etc.) YMMV on whether or not you can charge via usb connected to your computer.
So if you are discharging at a rate of -750 mA connecting to a usb port on your computer will still have you discharging at a rate of -250:
Code:
[COLOR="Red"]-750 mA[/COLOR] + 500 mA = [COLOR="Red"]-250 mA[/COLOR]
mine charges in the usb port, but only if I turn off the screen or turn off the touchpad completely. my ports only provide 500mA, and with the screen off, the touchpad draws about 50mA, so it can charge at about 450mA. With the screen on, it draws about 760mA, so even when it's plugged in the USB, it is discharging at a rate of about (760-500=260mA).
