So I just found this:
http://forum.xda-developers.com/showthread.php?p=12513699#post12513699
and a modified version for my HTC Aria phone. It works great!
Is there any chance a dev here can modify CWM for eMMC to work in this way?
Pretty sure the Nook doesn't need any HTC hacks to charge while off.
isn't it an issue with the cm7 builds not being able to go into deep sleep (or having that option turned of or something?) cuz it causes problems with wifi?
i thought the not turning off if plugged in issue was related to this

Not sure if you were trying to be a smart-ass or not, but obviously my Nook isn't made by HTC, however if I plug it in while it's turned off, guess what, it turns on.
I believe it's a Clockwork "hack", not an HTC specific hack, but I could be wrong.

My HTC Aria is running CM7 and this hack worked perfectly for it.

That is because it is actually supposed to turn on when you plug it in. You should have it plugged in and then shut off to have it charge while off. No need for a HTC clockwork mod, as the problem was only with HTC devices.
I know you can turn it off after it starts charging, but it's not supposed to turn on, as you say, the stock Nook doesn't.

Yes it does. Plugging in any nook while off turns it on.
Really? Guess I missed that in the day or so that I had an unmodified Nook.
Still would like to hear from a dev whether or not the system could be modified to not fully boot when connected. It seem illogical to me to have a device as power-hungry as the Nook boot up when you want to charge it, which will slow down the charging process.

Day of stock? Pft 10 minutes.
But yes, it does seem completely bass-ackwards to have it do that.
Isn't this driven by the whole USB then microSD then EMMC boat loader? It makes sense to me that the device be turned on when plugging in USB if your first boot device is USB.
Ahhh... didn't realize that the Nook had USB booting, that would probably kill this. I thought it was just SD, then eMMC. Bummer.

It's not wifi it's the touchscreen and other parts go too far into sleep and will never recover. This has nothing to do with charging or recovery.

After plugging in the USB turn your nook off by holding the power button. It will continue to charge

It's a hack implemented by Clockwork to replicate the same behavior that the stock HTC recovery does on your phones.
Before this hack was in place plugging in your HTC Aria while off would force it to boot into recovery with no real reason. This modification just boots into a "off-mode charging" screen which was implemented using the recovery ramdisk and kernel but a different userspace program.
The Nook doesn't need this as it's implemented in hardware quite well.
1) The nook will turn on automatically.
2) There is not enough power the bootloader will display a screen needing more of a charge
3) It seems, based on my testing, that the nook will continue to charge even when the device is full turned off.
So in conclusionL I am glad it worked for you on your HTC Aria, but this hack is for specific HTC phones and does not apply to the nook color.

From the B&N Nook Color User Guide:
To charge your NOOKcolor from a wall outlet, do this:
1. Assemble the power adapter and microUSB cable. Insert the large end of the USB cable into the matching receptacle on the power adapter.
2. Plug the NOOKcolor end of the USB cable into your NOOKcolor.
3. Plug the power adapter into a compatible electrical outlet. If your NOOKcolor was turned off, it will now turn itself on.
NOTE: Depending on how much power remains in the battery, it might take around 3-4 hours to fully recharge
your NOOKcolor. Do not turn of your NOOKcolor while it is charging.
NOTE: Once your NOOKcolor has enough power to turn on, you can see how much power remains in the
battery by checking the battery charge indicator in the right corner of the Status Bar. You may need to
drag the green NOOK symbol to the right across your screen to unlock your NOOKcolor and display
the Status Bar, which runs along the bottom of the screen.
4. Once your NOOKcolor has fully charged, unplug the power adapter from the electrical outlet. Unplug the USB
cable from your NOOKcolor.

Seems like there is a design reason for that.
What? You can boot off USB too? I didn't even know that!
sorry, i was totally off i guess, thanks for the clarifications guys.
I've powered my NC off after i've plugged it in and have come back to an already booted device.
This is not once or twice, it's pretty much all the time.
Maybe i just have a weird device? I DID buy it off craigslist used... but i've had no issues at all as far as user functionality goes in the month or so i've had it.

I knew that, but was trying to avoid that step.
Thanks for all the info guys, I still think since the Nook does charge after powering off, it would be nice if someone could find a way to skip that whole boot/power-down process so I can just plug it in and walk away.

Are you running the stock ROM? Mine did the same thing until I installed a different ROM. HC and CM7 both stay off when charging after I have powered them down.
I've been running CM7 nightly builds off emmc mostly, if not the tablet tweak ones before they were integrated.
Not something I consider an issue for me, but I've yet to do any complete wipe since I first flashed CM7. I might try phiremod over the weekend unless the fascinate forum blows up with new stuff (our 2.2 source code finally dropped today), in which case I'll do a complete wipe and see if the problem persists.
EDIT: Yes, i'm running with the latest OC kernel
EDIT 2: Ok... I didn't notice before, but I guess I have a sort of faulty usb? not sure but it flickers from time to time, like on and off. I've never really paid attention to it while it charges, but i just noticed that the light on the N went off and came back on a few seconds later and confirmed that it flickers from time to time on its own. So on the bright side i guess i don't have hardware with an anomaly, too bad I have a charging cable with a mind of its own
Are you running one of Dalingrin's Overclock Kernels? I'm guessing not, since that would be the only other difference.

I've been plugging it in and then powering it off to charge. Now I find out that the guide specifically states to not turn off your NOOKcolor while it is charging.
Will charging while it's powered off screw up the battery calibration?
edit: one thing I've noticed is that if charging powered off, the usb light never turns green when it becomes fully charged.
Hi there,
I followed the guide to install cm7 on internal memory and everything seems to be working except charging the unit. It seems as my NC charger/cable only works when I have it shutdown. If I'm running the unit the NC cable stay green and won't charge. Anybody having the same problem??
I had the same problem. In my case, it was the data cable.
It used to charge in autonooter 1.x, but it stop charging when I updated to cm7 (green light on cable and status doesn't show charging) Unless I turn the nook off then the nook cable will show red. Is it the cable that's defective??
J
Nope, it is not the data cable. I have the same exact problem. So I restored back to Stock to see if it was the cable, and the cable works fine booted into stock. Obviously, its a CM7 thing.
hi, i just installed CM10.1 on my HD+ and love it!! the only problem is that i have seem to have lost my ability to charge my HD+ while synced with my pc (debugging mode i guess). i have searched but i have not found anything that helps with the Nook HD+. so i ask here if anyone can help me out with some info. thanks in advance with any and all help.
I have a motherboard which can provide 3x normal USB power. It can only charge my tablets (Nexus7, Nook HD+, TF101 ...) while the screen is off.
I think this is normal. My USB ports can charge the Nook pretty quick.

hhmmm... thanks for for your input. everything seemed to work when i was running CM10. my HD+ charged with or without the screen on but since i upgraded to CM10.1 my HD+ doesnt charge when plugged into my pc. im trying to search for reasons why but still cant find anything.
I'm running CM 10.1 (6/30) build and it charges over my pc usb.
I did initially have a problem where it didn't recognize it as a storage device for copying files over,
but then I got it working. Not sure if it wasn't charging at that point but I think it was. Wish I could
remember what I did to get the mass storage working.

????? damn! i dont want to reinstall but if i have to i will.... you used the 6/30?? hhhmmm thats weird cause i used the same thing. is this what you used, [cm-10.1-20130630-UNOFFICIAL-ovation-emmc] ????? i would like to say that its no big deal but it kinda is. i used to charge while i loaded new comics, books & magazines. now i have to charge and load separately (yeah i know its not a big issue but i got used to doing both at the same time). btw, thanks for your input pdx!
Using the newest build of verygreen's emmc 10.1 CM.
Every so often I'll plug the HD+ into the stock charger and cable, and the light will turn amber for about 2-3 minutes, then it will turn green. It will say "not charging" instead of "discharging", but it won't gain in charge and will very slowly discharge.
The only fix is a reboot.
Any other similar experiences? Kind of annoying, since I'll let it charge overnight only to come back to a nearly-dead tablet.
Thanks.
You don't by chance have Usbhost feature enabled?

Nope, it's set on normal (non host) USB.
Would USBHost cause that kind of problem?

Mine only charges when Usbhost is off.
I'm running a July rom of verygreen and for the first time since running it my hd+ would not charge
when plugged in.
I normally leave it sleeping with wifi off.
I plugged in charger and it would not say it was charging.
did a reboot and then it charged itself.
I am using the latest version of verygreen's cm 10.1 before it went official and have no problems charging with us host off.
Happened to me once. Hard rebooted and the issue never appeared again
Hi,
I just got my Nook HD+ yesterday and installed CM10.1.3 (stable) right away. Great job guys, the OS is really running nice and smooth!
However I've got an annoying problem (2 to be precise):
The Nook won't charge from the charger and the LED stays green. When rebooting with the charger plugged in it goes orange, but turns green as soon as the Cyanoboot Logo shows.
The only way I can recharge the Nook is via my PC (although painfully slow, had I not found verygreen's Charger Control tool).
This leads right to problem 2: The Nook is not recognized by the PC at all via USB. On some of my ports it shows up as an unkown device, but there seems to be no traffic between the two (PID and VID of 0x0000).
Both problem could not be solved by updating to CM10.2 M1 or wiping caches or data.
Any ideas on this?
Thanks!
€:I just tried reinstalling the stock im (from my cwm backup) to see if it works in there. Result: nope, same thing. Charging from the PC, but not from the wall, no USB connection. However after connecting to my wifi and reporting available updates the Nook suddenly rebootet only to get suck at a Cynaoboot screen followed by a flickering TWRP logo. Which is rather strange since I thought I had just installed a full backup thus removing both of those.. So I am guessing there is still some stuff gone wrong left on the device. Installed 10.2 M1 again afterwards.
So how can I make sure that I get back to a truly clean state on all boot-related partitions without having USB/ADB access? Which can be wiped from CWM or TWRP without risking a brick?
€€: Oh well.. I just set up a bootable sdcard with verygreen's 10.2 binaries on it and started the Nook from that.. Same behavior So it seems like either my hardware is bad (which would suck since I'm in Germany and shipping it to the US and back would cost more than the Nook did) or there is some serious weirdness going on...
