I've come across a problem using Rack's dualboot CM9. If the Nook Color's been running and the battery has run down, connecting plugging in the stock cable + charger results in a green light on the cable and the Nook not charging. After playing around for a bit I figured out that if I reboot it or keep the Nook off it will charge fine. If I reboot and charge, however, the battery percent indicator does not update until after I unplug the charger. If I try to charge it again after unplugging, the light stays green and refuses to charge as before, even though the battery is not at 100%.
I wanted to rule out this being a problem with the charger first, and it seems that way to me but my knowledge about the inner workings of the Nook are limited. Any help is appreciated!
I have the same problem yesterday, and I just rebooted and work well now, don't know what's wrong with it.

I'm running the latest build of cm7 (7.02 I think). I've noticed even though the indicator on the included charging cord turns green when the nook reaches 100% under menu and status it says my nook is still charging. I've tried other USB cords with the same result. My optimus v running cm7 indicates its not charging after reaching 100%. Is this normal and is the nook still in fact charging after its reached a full charge?
In which place do U see that is still charging?
When the cable sign goes to green it means its full.
It says it under settings, about tablet, status. Also if you have the elixir app it says its charging. I'm just wondering if its a bad idea to leave it plugged in after its charged if it indicates its still charging.
Also something that may be of note is I'm running the 4/24 test oc kernel. I'm not sure if the kernel handles the device charging or not.
If the AC adapter cools off, the NC has stopped quick charging. My charger gets warm during quick charge, but I'm not sure if it stays in quick charge mode until the NC is 100%. Probably not. Probably switches to a lower charge rate when near 100%. I am pretty sure that the battery's integrated chip controls charging & I don't suspect the the OS can interfere. The battery is designed to protect itself from overcharging.
Cheers,

Thanks for the info. I do see the battery temperature drops some after reaching full.
My Nook Color quit unexpectedly on my because of a dead battery. I have been charging it for a day with various non OEM chargers. Previously when something similar happened I could plug it into my computer and it would charge without booting, but it no longer does this. When it boots it takes too much battery and it quits before it boots. Help!
You need an OEM charger.
Could also try finding the shortest uUSB cable you have and let it charge from the PC overnight.
So is that trick to charging a Nook when the battery goes completely dead? I've let this happen a few times, and I've always found it difficult to get charging cause it starts to boot and shows a message about not enough power, and just hangs there, but doesn't apparently charge.
I've got mine in that state right now, and since I found this thread I plugged into the OEM charger using the OEM cable. With that combo, it didn't start up. Handy thing to know. Kind of annoying though because when I'm traveling I'd like to just take one cable along for phone and Nook. I'll just have to be sure and not kill the battery then.
Hi Guy,
First post here. I looked around and could not find a solution to the problem so here we go:
So I have a U8800 X5 which I've rooted and installed Clockwork Mod and the MIUI Custom Rom.
I had been running that set up for about 3 to 4 weeks and it had been going great until recently when it started acting buggy. A few hours ago I used my phone until the battery fell to about 3% and while the phone was still on, I put it on charge.
It said "Charging" but the percentage was not increasing so I went to sleep with the phone still on charge thinking maybe it needed some time.
Now, in my sleep, the phone turned off and it will not turn back on. I have tried plugging it into another socket, charging through my pc, taking the battery out and putting it back in but every time it's the same result:
The 4 buttons at the bottom of the screen light up and the LED next to the speaker flashes red. There is NO activity WHATSOEVER on the screen itself.. I personally don't think it's charging.
Is it my battery? Is it the ROM? Is there a solution? :/
And I believe that the U8800 also works without a battery if the charger is connected (by getting power directly through the Mini-USB Cable).
It refuses to turn on when I take the battery out as well.
the same thing happened to me. it was a problem with the usb cable. i bought a new one and everything works fine again
Well, first of all try to connect it to a computer USB port with a different USB cable. If it still does not charge, then it might be that your batter is dead. OR if you're unlucky then there might be something wrong with your phone (though I don't think that. Most likely it is your battery)
You can try to connect your battery to a separate charger and see if it charges.
New to this ROM, is it a normal thing for the nook not to charge while on? I have to power off for the nook to charge up. Any ideas or just a normal side affect of using the ROM? Thanks!
I charge while it is sleeping.. no problem..
whats weird is a usb cable to computer charges it but not the original nook charger, only when I power off the device. I guess its not a huge inconvenience though it would be nice to charge with the wall charger.

And using original cable, not just a micro usb cable?

yes stock cable and wall plug. It wont charge while nook is on, but as soon as I power off the nook, the cable turns orange and charges just fine. If I power it back up, cable turns green like its all charged. If I use a regular usb cable while its on, it shows charging (USB). I have a new nook charger and cable coming from B&N so will see if that fixes the issue. But this cable was charging stock nook color fine, so I think its something else.

I don't think the replacement is going to fix the problem either.
I have seen this issue with CM10 on EMMC... I THINK my issue is due to multiboot from SD... Here's why... and I will do more investigating...
1. When booted to CM10 light is immediately green and nook shows discharging even when plugged in.
2. When booted to CM7 it works correctly... unless....
3. If I set deault boot to EMMC/Normal... No matter what boot i choose... immediate green light and no charging unless powered off... or sitting at the CyanoBoot menu
4. When attached to USB car charger... both indicate and charge normal.
I will do some more testing and investigation... like changing CM7 and CM10 install locations and performing above tests again and see if can narrow down the cause.
I have an SD card in the nook but its just for storage. So you think its a ROM issue with CM10? I put it on the charger last night and this morning it was at 39%, I just reconnected it and its orange again so I will see what happens.
so I installed the latest CM10 nightly and the nook at the moment is charging while turned on. How often is PA synced with the CM10 nightlies? I will do some more testing to make sure its not a fluke and falsely charging.
now its not charging while powered on LOL. Almost wondering if its the cable since the tip kind of moves a little bit. Powered off it does charge fine though. Weird.

Synced with the day of the build...there is nothing charge related in the PA framework so you should see identical behavior in CM nightlies, all things being equal.
so it must be a CM issue? I suppose I could go back to stock and see if it works there. the latest PA I see is from Nov 21 or am I looking in the wrong place? I just dont know why the thing charges perfectly fine with the device off, but doesnt charge correctly while powered on. I have to plug in a standard microusb cable which charges it while powered on.
It wouldn't be strictly a CM10 issue or others running the same ROM would be seeing the same problem.. I am not..
ok I am awaiting the brand new charger setup from B&N to arrive and will see if that fixes things. I tried CM10 based roms and CM7 based roms and the same thing occurs so it might be a bad cable. CM10 seems more responsive than PA, which I know is based on CM10.
I restored to stock 1.4.3 and the cable is charging just fine while powered on. I am going to redo the rooting and see if maybe I might have missed something on the install.
Nexus just died on me last night, out of nothing at all.
Plug the charger into USB, out for a bath and N4 give me a welcome with solid RED notification light. Unplug the charger RED light gone, but phone won't have any response no matter what key combination i press.
No fastboot, no bootloader, no charging animation, just a piece of brick with RED light when connected to USB power. Have tried to remove the battery connection and reconnect but yield the same.
Anyone have similar case? All the search i found is blinking RED light, unlike mine with a solid "RED mean STOP"
Plug it into the mains and let it gain power for a bit.. Battery might be completely depleted

Have leave it charge overnight, however still the same when i woke up this morning.
One thing i forget to mention, when i unplug the battery pin and put in USB cable, the same solid RED light appear, wondering is this having to deal with battery not receiving/release charge

It was plugged in the USB all night, or AC power?

AC, original charger.
This is so weird that i have idea what have went wrong, worst case scenario it should have boot up to bootloader even if kernel / ROM went wrong, but haven't flash anything new for the past few days.
