Title says it all...
When you plug in the nook color the screen wont turn off in Cyanogen Mod... This isn't good when you are using <2 amp charging (say 500 mA from standard usb) as the screen uses more power then the charge provides... so it actually drains the battery. Any ideas?
When you say it will not turn off, do you still have a display or just the backlight? When I am charging my nook in standby, I have noticed that the backlight will remain on until I tap the power button. That gives me a black screen

I noticed that recently with one of the later nightlies. I can still power off while charging though, can you?
I put it in sleep, I don't turn it off.
Same problem here. I just turn have to remind myself to manually turn it off whenever I plug it in. Probably some kernel bug or something?
Not a huge problem though. =)

Turn the screen off by hitting the power button.
This is not a bug but a workaround for a kernel bug. We fixed a bug that would cause kernel panic if you let the device sleep while plugged into USB. However, it would still eventually kill ADB so for now I start a partial wake lock when connected to USB.
Just wondering when this might be fixed? Having to worry about the screen being left on when plugged in is a problem for me. I normally charge my Nook from a standard usb. If the screen is on it drains the battery.

When what might be fixed? As Dal just said, this IS the fix for the time being. And it isn't a worry. Just plug it in, and hit the power button; your screen will turn off, and you will be good to go.

The fact it sounded like a temp fix "for the time being" is why I asked about timing. Turning the screen off is fine but I have had one case where the screen turned back on during the night and I woke to a nook that was almost dead even though it was plugged in all night. Even an answer like planned for next RC or for the final release of 7.1 would be helpful.
If there is not fix coming it would be nice to know that too.
I appreciate everything that has been done for the nook and enjoy using it as a tablet.
Using the high capacity cable is not an option. I have tried two in my nook and one would not charge it all and the second was very hard to plug and would sometimes charge it. A standard USB cable has always worked fine. I have read about bad high capacity cables taking out more than one nook so I won't even go there anymore.
Have this been solved somehow?
I have recently mounted my Nook Color on the kitchen wall and it is annoying to manually having to push the power button to turn off the screen, instead of having the screen turn off automatically after a specified time.
Where is the setting to make the nooks screen time out, and turn off while charging? Secondly does anybody have any idea why my tablet has been charging so slowly lately?

i think screen stay on while charging because "charging" is one of the possible SOD cause. That's why there is no options (and it's charging slowly because the screen is on..)
Ok thanks, I thought the sod problem was fixed.

Just press the lock button after you plug it in.

I normally do turn off the screen when I plug it in, but until just this morning the nook would die in my book bag due, to it waking up when the nook button was hit in my book bag. Thanks to somebodies help I rectified that problem this morning, but long story short I would charge it when I would go to bed, and it would be too dead to turn on when I plugged it on, so by the time it was ready to have the screen turned off, I would be asleep. Sorry for the long post.
Before I went to bed last night (11:40-ish), my nc was at 48% charge. This morning I woke up (7:30) and my nook was dead. About an hour later after charging it for a bit, I noticed my screen somehow turned back on and I hadn't even touched it. It seems the screen timeout is broken, or the option screen always on when plugged in is broken, because I double checked to make sure it was off. Btw I'm on Nightly 177
May just be my nc though.

It is not broken, nor is it your nook... this is common just like stock B&N ROM works.
If it is dead when you connect charger... when it gets around 15% it turns on... if it is not dead when you connect charger... it does not go into sleep... you have to manually turn off screen by short pressing power button.
Its availabe under Settings->Applications->Developement->Stay awake
but this never works for me here(unselect above option), my screen will never turn off automatically on CM7 while charging.
It does seem like the nook is charging much slower on CM7, even when the screen is off, I remember it charged fairly quickly on stock, but on CM7 it seems like it takes hours, I have left it charging over night, and it has not charged all the way before. I could be wrong though.

I have the same problem too. Is there a way to resolve it? The reason I'm asking is before I turn my device off and go to bed while leaving it to charge and when I wake up, the device is somehow turned on (I have come to realise that the NC turns on by itself at random while charging) and the screen never goes to sleep which causes my NC not to be recharged even after a whole night.
To actually turn the NC off when charging you have to attach charger... THEN hold the power button in until you get the power menu... select Power Off

Of course I did that. What I'm saying is that my NC still randomly boots up. Sometimes after a few minutes, sometimes after a few hours.

Mine does that too (turning on while charging from powered off). It is telling you that it is now charged enough to operate. My solution was to not let it run down so far before you charge (below 15%). And don't turn it completely off. Plug it in and just turn the screen off. Then it charges the whole night without turning the screen back on.
I wonder if it would be possible to have the nook color shut back down if it loads into the os or recovery from a charger activation.
With mine as Long as the battery isn't dead when I plug it in, If I turn it off while its plugged in and not move it at all it stays off, but if I move it in any way it turns back on. Don't know why but movement fires it back up when plugged in.

Seems to be a bad connection....same thing happens wirh my nook also...I plug the cable in, put the nook on one of my floor shelves, turn it off, and leave it to charge overnight....then again ANY kind of movement while the cablle is plugged in to charge OR use usb storage makes it disconnect....maybe a bad cable, unfortunately I haven't found them in stores anywhere lately..

I was wondering if anyone else was having this issue.
I've charged my Nexus7 overnight on three occasions. Plugging it in before I went to bed (~1AMish) and getting it on my way to work (~8:30AMish). Out of those three times, on two of them, when I went to get my tablet the unit was powered off. I know for a fact that when I plugged it in, it was on, and no one touched it in the meantime.
The most recent occasion was this morning.
On all three occasions, the unit still had 40-50% battery life left.
On two other occasions, I've charged it during the day for a few hours, and it was fine.
Additionally, I've never had the unit turn itself off overnight when it wasn't plugged in. And I'm using the charger/cable that came with it.
Lastly, the first occasion was on the stock kernel/rom, and the second was on the motley kernel (but stock ROM).
So it seems like something is causing the unit to power itself off if it's on the charger for too long. This is concerning, because the only thing I can think of is that it's overheating and shutting down as a protection mechanism.
Any thoughts or ideas?
Plugged mine in for the first time last night at 11:30. Slept till 8, hit the power button and everything was fine.
Basically, no issues here.
Was it fully charged when you switched it back on? I ask because I shut mine down for the overnight charge last night (plugged into a laptop, not the wall - there's only one socket near the bed and my battery-sucking phone gets that juice), and when I woke up it had only gone from ~30% battery to 55%.

I had this happen to me on the first unit I had... I was actually using stickmount to transfer some data and left the usb adapter plugged in for about an hour and when I picked it back up it was DEAD.... I could not get it to boot up at all until I did the recovery (power/volume) method and then everything was fine but I returned it anyways cause of a defective screen... I am now on my 3rd unit from Sam's Club and I think I might have a keeper...? (Knock on wood) :fingers-crossed:

Yes, it was at 100%.
Keep in mind that charging via computer's USB port takes much longer. Maybe your laptop went into sleep mode and shut down power to the USB port?

Nope, my fiance's phone was plugged into the same laptop and it was fully charged in the morning. And as a general rule, I've never known the computer to automatically sleep while on AC power, even when the screen is closed.
Thank god i'm not the only one experiencing this. My nexus 7 always seems to turn off after I leave it overnight plugged in for charging. I thought it was a kernel issue but i've switched kernels and i still experience it. Still unsure as to what is causing it.
Same here. Its odd it only seems to be for an extended period of time. Also my battery was indeed fully charged. Should I exchange at Sam's?

There is nothing else wrong with the tablet. I have a feeling it could be some sort of hardcoded feature where if it notices that you're plugged into the wall charger with 100% battery and the tablet is in deep sleep for a certain period of time, it automatically shuts down.

Ikr. First time it happened to me I was like wtf? It might to stop the 2 amp charger from overcharging? My unit is fine, I think the sound is just right. I might get that squaretrade warranty though.

Well, I feel a little better that I'm not the only one with this "problem".
The question is, is this a "problem" or a "feature". I guess we won't know unless we ask Google/Asus (good luck getting that answer) or enough people respond saying that it happens to them too. But if people start saying it does not happen to them, it makes it more likely to be a problem....
This happens to my phone due to overheating. The tablet does run hot when charging. See if there's a temperature logging app and run it overnight.

It would be nice if it would just cut off the battery charge and run directly on A/C. But I guess I would rather have it power off than explode.
isnt bad to charge it overnight like i believe from 1% to 100% chrge is like almost 3hrs fully chrged.. i just alarm myself for 3hrs to check if its fully chrged already then unplug it

True, it's not good to constantly charge the battery once it's full.
Most devices however have a built in charger kill switch once it reaches that point. Laptops for example will switch to A/C power and only start recharging the battery once the level drops to ~95%. I believe my phone does this as well (SGS2).
I guess I'm OK with it turning itself off, assuming that it really is a safety feature. My main concern was something was wrong. It would have been nice if they mentioned this in the 100pg Nexus Guide eBook though .

I want to add my own observation -- mine was almost fully charged, I plugged it to my computer's USB, turned the screen off, walked away. A couple hours later, the Nexus 7 was turned off. But I was shocked to find that, pressing the power button couldn't turn it on. The first thought came into my mind was that my computer did not charge the Nexus 7 and the battery ended up completely drained. So, I plugged it to the wall charger, left it on for a day. 1 day later, I tried to turn it on again. No, it didn't work. I was panic and decided to Google about how to reset and checked if I could wipe it and sent it back for a replacement. I found that pressing the power, vol up/down button at the same time can force a reboot. I tried that and bingo, it booted into the bootloader. Before I wiped, I decided to try to boot back to the Android OS. Surprisingly, that worked. I was happy and decided to ignore this incident. Then, today, it happened again. This time, I immediately used the power + vol up/down trick to reboot, and that booted me right back into Jelly Bean. I checked the battery status and it's fully charged, which meant my computer was charging it all along. For some reasons, the Nexus 7 would just turn off itself. And, in my case, pressing the power button alone would not reboot it.

Sounds like to me that it's hard locking, not "powering off", and you're forcing a reboot. Long-press of the Power button should do the same thing.
I can't say I have much to offer in regards to this issue, but am I correct with my observation that everybody experiencing this issue has experienced it while their N7 was plugged into a computer of some sort for an extended period of time? Has anybody had this happen when plugged straight into the wall outlet?
Here's another update with an interesting 'twist' since my last post.
I've charged it twice in the meantime. Once was, again, overnight, and I woke up to find it powered off. A simple "on" press brought it back on.
However, on Saturday, I used it heavily and was down to about 40%, so I plugged it in around 11AM. I meant to grab it around 3PM when I went out, but forgot about it. Got home late, and went to look at it at about 11PM (12 hours later). It was charged to 100%, running off the A/C power, and still on.
This is weird, because if I leave it plugged in "overnight" for 8 hours, it will almost always turn off sometime before I grab it. But when left plugged in during the day for 12 hours, it stayed on. I wonder if it handled the situation different based on the time of the day???
Hi,
I just got my touchstone and I discovered the following behavior (I run the latest CM9 nightly):
the touchpad charges until it's full, it wakes up and says 100% charged and stops charging.
After a few minutes when the battery level drops to less than 100% the loop continues.
Thus, there's a charging cycle every 5 minutes. Doesn't this affect the battery life?
Also, can I prevent the touchpad from waking up when it's full? I put it on the touchstone,
turn it off (I don't want to show a dock app), but it will wake up every 5 minutes or so.
Thanks!
Interesting. My touchstone doesn't seem to do that. I put my touchpad on there at night (running cm9) and I will hit the button to turn off the screen. The screen never comes back on until I pick the touchpad up off the touchstone in the morning. Mine doesn't show a charging loop either. It just shows full but with a lightening bolt in the battery icon in the morning. I assume that it just keeps sending a slight charge to keep it at 100%.

Mine did this on cm9 alpha 2, but using the latest nightly it works just fine. Also I've had my Touchpad around 11 months and use it regularly its pretty much been switched on the whole time and always returned to the touchstone each night, and my battery life hasn't reduced.

Hello,
Wondering if any body else has been experiencing this and has come across a solution. When I put the S6 Edge on the charging pad (new one that came with the phone at Best Buy) it either works without issue 25% of the time, or the phone will say wireless charging paused after about 30 seconds and then the charging pad will flash 75% of the time. I am being sure to place the phone centered on the pad and on its back. Sometimes it will happen so many times in a row that I try unplugging the pad and restarting the phone and then it works, but I do not want to have to do this every time.
A lot of people are having the same problem and so was I.
Grab your phones charger and base and use that.
I think the long cord that comes with the wireless charger is causing the issue.
I have the same problem,,,half the time I put the phone on the charger and it works and the other times it doesnt.

I've had similar behavior although not as bad as you are reporting.
