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.
Hey there. New around the Kindle Fire HD parts as I haven't actually received mine yet..
But, I was curious as to whether you guys could answer a question for me!
If you have your Kindle Fire HD turned off and then apply power to it through the USB, does it turn on? I mean on as boots into Android, not simply displays a charging screen of some sort.
Are you on Stock or the unlocked bootloader?
And lastly, I doubt anyone has tried this.. but I might as well ask! Has anyone tried to remove the battery from the Fire HD and turn it on using only power from USB?
Appreciate the answers.

Hey there as well. In answer to your questions...
1.) Yep. It does power on when you plug in USB. No charging screen, just the whole OS (unless there's not enough power to boot Android, in which case yes, there is a charging screen).
2.) I have the second bootloader installed, with Chameleon OS installed.
3.) As for opening up the Kindle.. that's a gray area for me. If I knew what I was doing, I'd open her up, but I don't know if I'd be able to get her back together. Lol
Hope this helped

When you say "unless there's not enough power to boot Android.." do you mean the battery needs some level of charge before the tablet turns on?
For instance, if I left the tablet on and drained it down to 1%, then plugged it in, would the tablet boot straight into Android or would I get a charge screen?

If you drained the battery (and some ROMs do that in a bad way), the Kindle will only show a charging screen (at least mine does). However, I can't remember if this was when I was on Stock OS or on a different ROM.
So yeah, it does seem to need some level of charge before Android will boot.

Awesome. Appreciate all of the info. I'll see if I can't set Tasker up to turn off the device when the power is removed. If that doesn't work, I'll go build my own version of Android that changes the battery shut off percentage to something high enough to make sure it will turn on as soon as power is applied.
Thanks again for all of the info!
Hi guys,
So here's my list of problems i have encountered with my recently purchased asus tf701t (4 weeks back)
1 - the docking station doesn't charge since day one (although it's AD02, but from the october release), always at 0% with or without the tablet attached.Nor does it charge the tablet when its attached to it, rather drains its battery.
Even left it charging over night.
2 - 3 days back , vol up key stopped working without any apparent physical damage.
so far have tried:
contacting asus customer support without any positive solution, all they could come up with was that i do a "whip data" which i did to no avail.
currently the rom is stock rom JB 4.3, with latest US firmware and isn't rooted.
The problem am facing is i can't ship it back since i bought it online and paid a large amount for it to be shipped to my country, so shipping it back isn't an option for me.
PS: while the dock is connected to the wall charger and if i go into fastboot mode (power+vol down), the blinking of the 3 icons is painfully slow as compared to when i remove the charging cable. Also the docking station shows that its charging but actually drains the tablets battery instead.
so here's what am thinking will rooting and changing the firmware from US to ww be of any help?
Is there anything that can be done to fix the charging issue + the vol up key issue ?
also is there any way i could perform a triple whip data or cold boot without my vol up key working?
Please help me guys..............
Sounds like a hardware fault to me - I don't think rooting or installing a custom rom will help at all unfortunately.

Good question! I'm struggling to think of a way to do it as the volume up acts as the execute button......
hum... seems like am in a fix here. Not what i had expected from my first android tablet experience tbh.
Hope we get a work around for my vol up key problem which apparently had no problems 3 days back.
Another thing i have noticed is after three consecutive "factory rests" ,docking station when attached to a wall charger along with table "falsely" shows charging of tablet (instead it still keeps draining it battery) when its screen is off and goes back to not charging sign for tablet battery when it's screen is switched back on.
Throughout this time, the tablet battery shows its charging which it isn't. Also when the docking station is connected to wall charger independently it's charging (orange blinking led) does not light up....!!!:crying:
My Galaxy Tab S2 9.7", updated with the latest firmware (T815XXU2BPG2), has started to power on when fully charged. Usually I power off the tablet and go away while it charges. In the last days I find it powered on and fully charged. I checked that it doesn't power on on the moment is connected to the charger, I simply find it powered on after some hours it is connected. I tried to charge it with another original samsung power adapter with the same results (power off until charge is 99% and then I found it power on when fully charged). Someone could explain this strange behavior?
well, this explains why I always find mine discharged after I unplug it when my smart cable shows that the tablet is fully charged without opening the smart cover.

Found exacly the same problem on this forum ttp://forums.androidcentral.com/samsung-galaxy-tab-s2/709518-tab-s2-turning-itself.html (sorry yet can't post links) Any suggestion?
Hi,
I have exactly the same issue. No solution ? Thanks a lot
Still no solution. Same problem on my wife's Galaxy Tab S2 8.0". Definetely a latest firmware's problem.
I don't think there ever will be a solution. We're stuck with an always on Tab after charging.
im getting this too on my s2 8", glad I'm not the only one. it never used to do this i believe it happened after the last update...
Well, it seems that the latest firmware update fixed it. I charged it twice and so far it has not turned its self on.
Same here. Latest update solved the problem.
Hi,
I need do this modification in a Samsung S9 for my project.
I will put S9 inside a box and only space out of box is the USB-C for charging.
When battery over, I would like to plug the charge cable and the smartphone turn on again without press any button.
I search a lot, read stackoverflow/quora altought without sucess.
At this moment the S9 is rooted.
Someone could help me ?
This is not feasible by SW Mod.
Most likely you need to modify the FW boot loader on the MOBO.
Possibly it is momething to be implemented in the TWRP but also this rely in pressing some buttons on the mobile.
