I had my Nook HD unused for a couple of weeks and now I can't turn it on.
The tablet has been charging for more than 10 hours.
When I plug the cable the green led lights. It also lights for a few seconds when I push the power button if the power cord is plugged. But any signal of life in the screen.
I've tried to hold on power button for 15-20 seconds and also power button + Nook button and many other tricks I've read in other forums, but anything works. The screen is completely black.
I haven't found any thread with a solution for this specific model and I feel really worried. The tablet is almost new, just 2 or 3 months and used a few times.
Any help is much appreciated. Thank you,

Have you tried turning it on whilst it is plugged in? I seem to remember that the devices only charge when switched on, but not sure how that operates when the battery is very low. If there is no failsafe for low battery, charging for 10 hours when the device is switched off wouldn't help.
If you can get the device to turn on whilst plugged into the wall socket, you may be able to start a proper charging cycle.

I tried with the nook plugged and unplugged, no success.
So, you think it is not possible to charge the nook if it is switched off? I would say that this is an incredible error of design. So, should I consider it lost? I've used several tablets/ebooks in the past and never happened something similar, I'm really disappointed
thank you for your support. Since I do not live in UK nor USA, I can't see how to solve the problem, so it will go directly to the trash

There are posts on this forum and on the XDA forum both saying the HD+ will not charge if switched off. I realise that you have an HD, but the XDA forum post went further and noted that all Nooks need to be switched on to charge.
If you plug in a Nook HD+/ HD that is switched off it is supposed to turn itself on so that it can start to charge up.
I know that the Nook HD+/HD's need a strong electrical current to charge.
Wulfraed posted on a different thread that:
'Standard USB provides 500mA (five units of 100mA distributed over four ports). Some charge-only supplies may provide around 1000mA.
Problem: HD/+ wants closer to 2000mA, especially if the LCD is alive. The HD/+ charger output is 2A @ 5.1V -- all fed to one cable.'
If you are not in USA or UK, your power supply may be the problem.
If you are trying to charge it from your computer, the USB port may not be providing enough power to nudge the HD into turning on.
If you are using an adapter when you plug the HD into the power supply, it may be effecting the current flowing too.
Which method are you using to try and charge it?

I'm glad it's working! The UK and USA B&N shops both have international charging cables, so you should be able to find one that works for you - don't know if they will ship internationally. Maybe find it on Amazon in your country too.
You may find that now the HD is fully charged you can top it up from your pc when the screen is off by plugging the HD cable into your usb port.
These batteries last much longer if you charge little and often.
