    Nook HD+ refuses to charge except when hooked up to computer

      i've tried to charge it with multiple usb wall jacks and never can get it to charge. if it is hooked up to them the light by the bottom of the nook stays green no matter how long and never gains any charge. and even when its hooked up to my computer the nook never says its chargingbut it does gain a charge. any kind of fix to have it charge off my laptop ?

          As I understand it, the HD+ is designed to require charging from the supplied wall charger only - standard USB ports do not provide adequate amperage.

            S....do you not own the charger made for the HD+? I think there is a question as to the volts required to charge your device. I have only used the charger that goes with the HD+.

              Saera, is your question

               

              1) Nook HD+ charges from your computer, however it does not charge from wall plugs?

               

              or is it

               

              2) Nook HD+ does not charge from computer?

               

              *****

               

              If it's the former

               

              a) Using the wall plug provided with HD+ is essential or using a similarly rated wall plug.

               

              b) Make sure your connection of the USB cable into the wall plug is properly done.

               

              *****

               

              If it's the latter

               

              Nook HD+ will charge off computer very slowly. IT's best to have the screen in sleep mode and not be using it.

               

              If you're using it it won't charge since battery life needed to run screen and processor and WiFi is more than the trickle charge of the USB provides.

                Well if you are needing a replacement AC adapter or a 2nd one. I have found that the LG Nexus 4 wall charger works perfectly on the Nook HD / HD+.

                 

                The Nexus 4 charger outputs @ 5V 1.2 Amps.

                 

                Hope that helps.

                    Interesting that you found a charger, besides the Nook HD+ mfr. one, that works. 

                     

                    I would have sworn that I had other ones that worked when I first got it, but have not been able to do that since.  Also, difficult to tell anything about charging without external metering.  I have noticed that the charge light goes green, without the HD+ being charged, when I use other chargers.

                     

                    Internal regulator, I am sure, plays a part in this, and I am wondering if maybe it accepts charge from high amp chargers, but only if it gets really low on charge? I will do some more experimenting when I get time, and I have a special USB charge meter coming that should help tell me what is really going on. Maybe there is variance between the chargers or even other Nook HD+ builds. My limited testing would not reveal anything about that.

                     

                    Has anyone had any luck with it charging reliable from generic 3rd party chargers? 

                     

                    Thanks all

                        I have done a few experiments.  Apparently the HD+ will charge with some chargers, but not others.  I have tried several Samsung (galaxy 3 and note 3) chargers and even a SurfLink hearing aid device charger that work well at 1.0 or 2.0 amp rates..  However, other non OEM chargers do not seem to work right unless strictly emulating the slow output from a computer USB port.  I am passing that on since you may find that your phone charger will work in a pinch as long as you have the Nook HD+ cable to use with it.

                      I have found that the Jawbone charger works... output 5V @ 550mA ... nothing else worked Apple, Kindle, etc. Hope it helps.

                          I have found that my HD and HD+ seem to discharge while charging at less than 2A even when the display is off.  I've turned off the Live Wallpaper and syncing but I much preferred the "standby" mode of the NC and NT to my experience with the HD and HD+.  I find I have to turn them completely off rather than put in standby to keep them from burning down power during the day -- and I've gotten to hate the raised buttons as those are the only reason I can come up with for seeming spontaneous power-ups.

                          I am having the same issue as the original poster. My Nook charged for several months with the Nook charger but then started failing to charge. With the charger, when I connect it to the Nook HD+, the light stays green rather than turning amber and it actually discharges rather than charges. On the computer, it will charge but it takes 8 hours or more.

                           

                          I tried buying a new charger from B&N and does exactly as the old one. However, it seems it will charge on any of my computers (again, it does take quite a while). Any other suggestions?

                            I am traveling and assumed that I could charge my Nook through my computer which doesn't seem to be happening. It is just one more thing that surprises me. Why B&N would limit the flexibility of their device is probably one reason why the Kindle is used more widely. Don't get me wrong, I love my Nook but it is funny when the device isn't really competitive that way.

                                The USB 2 specification is that a powered hub can provide up to 5 units (where "unit" is 100mA at 5V) distributed among four ports. That means a maximim of 500mA if only one port is used.

                                 

                                The HD/+ requires over three times the power to charge -- it comes with a 2000mA (2A) charger.

                                 

                                There are devices with more powerful USB sockets, but even those tend to max out at 1A. Ports with a lightning bolt emblem are charger ports that are powered when the computer is turned off. They may boost to 1A when computer is off, dropping back to 500mA when computer starts. My TV has a 1A port meant to power a small hard drive for playing media files without needing a wall socket. Neither of those will charge an HD/+

                                  [emphasis added]

                                  Could B&N have given you the "flexibility" you seems to want, i.e., the ability to charge using a computer USB?  Yes.  But let's stop and consider doing that from B&N's point of view:

                                   

                                  Option A (USB charging):

                                   

                                  Pros:  You can charge with your computer.  Possibly cheaper because don't have to supply a powerful charging unit.

                                   

                                  Cons:  It will now take about 6-8 hours to charge from about 15% to 100%.

                                   

                                   

                                  Option B (Wall charger)

                                   

                                  Pros:  Can charge in 1 to 1.5 hours.

                                   

                                  Cons:  Complaints from people who don't read the owners manual.

                                   

                                  The real problem is that B&N did give you flexibility you just don't appreciate it.  They sold you a charger (the wall unit) and a cord that can be used for both charging (with wall unit) and for data transfer.  They could have cut down on the confusion, I suppose, by making an integrated charger/cord and a separate data transfer cord that was labelled "Not a power supply.  Data only."  But they were trying to save you some money.  And to avoid all the complaints from people who would be asking why they needed two cords. 

                                   

                                  So, do you want faster charging or not?  That is the question.  If you do, you need something to supply the proper amount of power.  Why don't you send your complaint to your laptop manufacturer and ask them to give you the option of turning up the power output of your USB port?
