Cm7 charging screen timeout & charging

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..

[Q] can't charge or turn on my nook hd+ at all

My nook was idle for a day or two, as I remember I hv shut it off.
But then yesterday I try to charged it, the light was green then turn to red, n then it went off, usually the nook would turn on right after I plug the charger. So I didn't notice it until today, and I tried to turn it on by pressing the power button, and the N button together as well, both didn't work.
It seems that I can't charge it or turn it on. Everytime I tried to re-plug it to power or press power button while its connected, the light went on in green to red then off again.

Connect your charger. Let it stay on charger 20 min. Then try push n button. If this not bring screen on then try push power button for 5 sec. Again if not then try power and n button combination.
Hope this helps.

Thx! Turns out tht external charger didn't work.

I think that last opinion is make CWM sd card (without CM10) and insert it do device, then try to switch the device on (with charger trick or power button). If you then get it live all is ok. If not then last change is wait when battery goes empty and charger wakes it up.
Actually i predict that item is itself faulty and you must return it for change (maybe not faulty at hardware side, only OMAP inside code got corrupt).

I don't know, that might because I rooted my device, and I did sth wrong. Sometimes it would reboot itself, since my cmw card was inserted, it would load tht root page so I found out. But I live in Asia so returning the device might be too costly, probably won't do it.

It could be several things. The most likely is it was trying to update itself and could not because the CWM card was there. I don't think your device is defective.

Now i can say same. With first information things was other.

...It's more or less a known bug to those of us who use CM10 (even to some who use stock), the battery simply often can't tell how much she has left. So she may fluctuate from 1% to 26% to 0% a moment later . In one such moment my Nook HD+ shut down (went from 26% to 0%). So I put it up for charging thinking (naively) that it would boot up ... it didn't, now all I get is a charging icon that never goes away (orange led remains lit). What's more I *know* it has some charge (the "26%" was the right value) and I know the battery works, so what prevents it from starting is the "battery charge sensor".
It's a pretty silly way to lose your (my) tablet over. Even more so given how much I grew attached to it for my workflow. So what's next? Is there a secret way to convince it to boot. As I said both the hardware and its software is in top condition. I guess an alternative would be to ship it back for replacement but I'm afraid that I've lost my receipt and -as I said- it's a silly way to lose your tablet over, there *has* to be a (fast) way out...
BTW when connected to my PC my device manager briefly shows an "Omap 4470" unknown device (with an exlamation mark) which goes away few secs later, so I cannot attain ADB control over my devices either (sadly)....

If you are running CM10 or 10.1, there is an easy way to connect with ADB. Do it wirelesly over wifi. That is built into CM. Just enable it in the developer options. No need to mess with the USB cable and windows drivers. You can do the same thing with rooted stock by installing an app called ADBWireless.

At the time that could not happen , since (as I had implied) my nook was not booting to begin with...
Anyhow, what I did was to leave it for three solid hours on the charger, and after that period of time it booted on its own wiithout warning. It's the first that such behavior was/is ever present to my nook and it's deeply worrying. A battery fix for the CM kernel couldn't come any sooner; now, if only verygreen was around

There's a few ideas on a couple of other threads including putting it in the fridge, etc. Question, if you plug it in, does the charging light come on? Does it come on after pushing the power button or the N button? If so, take your SD out, leave it charging overnight and try again. It often reboots when in this state and if there's an update problem, that could be the issue. Also, it is sometimes erratic on when and how it charges, be careful with the connections.

As I said it came up on its own, without warning after leaving it for 3 hours on the charger...
As for your question, the led (charging light) was on all the time but it would only show me that it had no battery (couldn't charge even though it was ... charging?)
Maybe the fridge makes sense in those situations, as it was indeed into a (relatively) hot environment and maybe it couldn't charge as a safety against overheating and since (at the same time) it also thought it had 0 battery. But what I can't understand is why needed 3 hours before starting to charge up, it was already cool enough long before ... strange things are/were happening with my battery all along and I worry...

Yep, I've noticed the same thing a few times. It no longer panicks me. When it doesn't turn on, I take out the SD, plug it in, wiggle the connector a few times, and let it alone. So far, it has always eventually rebooted, often as you say on its own. Quirky, but not fatal at least. One poor guy on here never did get his to turn on, but the key was the charging light,his didn't come on.

Need help cannot turn on Nook HD+ at all
Hi!
I cannot turn it on at all and it won't reboot.
It went out some point I didn't watch it. When I connected it to the charger the LED next to the connector starts blinking amber and green for a few seconds and then stays blinking red and makes a high pitched noise.
The only reaction I get is when I press power on an volume down after some time - it display turns on an shows a charging sign - but it never really seems to fully charge. I left it on the charger over night - still the same. Once the display blinked and showed “nook” but went out immediately after a few milliseconds.
Might it be some kind of bootloop!?!?
What combination to press to make a reset?
Thanks in advance for any help

[Q] Power on with CM10 tricky from dead battery?

Seems I cannot find any other people asking this question
Basically I have Nook HD+ rooted and CM10.1 and it works great. I have google market on there and the original Nook OS has been sent to the nether region of hell where it belongs. So it's a pretty decent basic android tablet.
But when I let the battery go to zero and it shuts itself down, it seems that it doesn't turn back on so easily.
I'll charge it overnight and then attempt to power it on, but it doesn't do anything. I see the screen backlight come on but no "nook" logo.
So then I try plugging it back in and hold power and the "n" for 10 secs or so. I'll see the screen turn off.. I'll do that a few more times and finally I see the dead battery logo show up..even tho I charged it all night.
So then I let it charge a bit longer and try again with it still plugged in and finally it turns on.
I was just wondering if others saw this and if there was some proper method I should be using to restart it to avoid this.

Yeah, my nook was doing that same thing for a while. Now though, I let the battery die and I can't get the thing to turn on at all. No backlight lights up, no battery charge icon, the thing's led just glows green for 2 secs then flickers to orange and stays orange for a few secs and then the led turns off. No matter how long I hold the power button or the power plus nook button, nothing happens. I hope my tablet isn't dead forever. Anybody else have this problem and find a way of fixing it?

I also forget to charge mine and it got discharged. I charged it for a bit but couldn't power on. When I plugged the power cable it showed orange light. After changing the power socket and repeatedly press power button for like 7 secs it turned on with 28%. I'm Using CM10.2.

Just keep trying.. i noticed my backlight was so dim that i wasn't sure it was on either until i turned off all lights... then after holding power for like 12 secs i saw it go even darker so I know my backlight was on now.. but like you said.. no logo. Just extrem0 said.. you gotta keep playing with it, unplug it, plug it in again, etc.. it's really hokey. I've been sure to keep it charged up since my last post so I am just avoiding the problem. But it is stopping me from recommending a modded nook to my friends and family because the first time this happens they will come crying to me to help them.

I also have this problem on my Nook HD+. I don't think there is a solution for it, so I'm going for a warranty.
However, before you go for a warranty; flash the stock ROM back on. You're probably think how do I do this with no battery? Well, once your Nook boots up, your tablet will not charge at all. So, we need to charge your Nook whilst it's powered off. Again, how do I go about this? Well, turn on your Nook charger from the wall socket, but do not plug it into your Nook yet. Now, hold the power button on your Nook (ensure that your have no battery at all, and that your Nook does nothing when you hold the power button). Whilst holding the power button on your Nook, plug in your charger. It should turn green, then turn orange. It should stay like this for a while.
Give it a couple of hours, and it should charge up to around ~60% (you may be lucky if it charges more). With that much battery, put the Stock ROM back on and go for a warranty. Don't rely on this method for too long, as with time it will also stop charging with this method. At the moment, it will not charge when the Nook is turned on. Go for a warranty whilst you still can.
All the best.

Dead Atrix HD

Hi.
My white Atrix HD is dead. It does not power and does not give any sign of life.
Phone was working perfectly, then it froze and after that it shuted down... never coming back. Was running stock.
First I thought it was the battery, but checking it with a voltmeter it shouws around 4Volts so it's OK for at least power the phone, I also recharged the battery separatly with an external charger...
Phone is still not powering. I tried every key comination to no avail.
If I plug it to my PC with the battery connected the green led appears for a while, then it goes off...
If I connect the phone to my PC with out the battery, then the green led stay lit forever...
What do you think it could be? Battery is dead? (It does supply voltage but you never know...)
Maybe a burned fuse on the motherboard?
Any help pinpointing the cause of the problem would be greatly appreciated.
Good luck!

Did you try to replace with other battery ?

Try this. While plugged into a power source, hold all 3 buttons on the right side. Once the light turns off, unplug the phone and hold the power button (top of the 3). Once it gets to the boot animation, you can plug it back in. Or you can just check the battery level and make sure it's not something wrong with the screen by doing what I said but never unplugging it.

Nothing... It's just dead. I think it might be the battery but first of of all it does give voltage and second i don't have other battery to test it. I could use another's phone battery but don know if that would work.

If ur adventurous enough to open up the phone like u would open up to do the EB40 battery mod, try to disconnect the battery completely by un-screwing the battery from the terminal for 30 seconds. Then connect back and try to power up. What you described happened to me once when I was doing the mod and it worked like a charm.
Good luck!

[Q] [Help Thread] Nook HD not booting at all

I recently went on a 3 month trip. Before I left, my nook was working perfectly fine, when i got back, it didn't work at all. It's not dead because i left it plugged in overnight but it still didn't turn on. when i plug it in the LED goes from orange to green and then off (or green to orange, i can't remember). The screen doesn't turn on at all. I can't get to recovery either.
This is a Nook HD, I believe it had CM11.
:crying:
Can this be fixed
or should i plan it's funeral

Same here
The same has happened to me. Screen doesn't turn on, but there is power, I can play it into my laptop and something is there, just not enough.
Good excuse for a new tablet!

It can be fixed. I've done it before. It has to do with the fstrim not being compatible with certain hardware versions of our device. If I can remember how I fixed it, I'll post it here. Trying to fix mine (again).

If would be fab if you could fix. Seems to be a common issue

I was able to fix it. YMMV.
1) Make sure the Nook is completely off and unplugged
2) Take out your sdcard
3) Hold down power button until the "battery depleted" icon shows, then promptly plug in the power before the icon disappears.
4) Let it set. The screen will go black, then it will attempt to boot and get stuck on the faint black screen, but this time, the charging light should stay amber.
If you want to be safe, wait until the device reboots itself. That could take hours though. If you're plugged into the wall wait at least 30 - 45 minutes before holding the power button down til it shuts down and then rebooting it (with the sdcard inserted).
Good luck, I hope it works for you.
EDIT: Also, I've read this may also have to do with wifi sending the device into some sort of strange bootloop when the screen is off. I personally believe it has more to do with the fstrim of JB but perhaps changing the wifi sleep policy may prevent this issue from happening again. I'm skeptical, but figured I'd pass that info along if anyone wants to try it as well.

Not sure we have the same problem. My screen doesn't come on at all, I don't get a battery depleted icon, no matter how long I hold in the power button. The only sign of life I get is when it's plugged in, when it goes from orange to green after about 10 seconds.
Thanks for the help, but I think it's a lost cause.

YMMV. But mine was the same issue. You should be able to get the icon by holding the power button down for 5 or 6 seconds. I'd say just eff with it until that icon appears. Try different button combinations. I used power and home trying to get the icon to show.

Anyway... since people are continually running into this kind of issue...
Give or take 21 seconds after turning orange it turns green during actual boot cycle into rom
Give or take 10 seconds after turning orange is cwm internal recovery.
After about 10 seconds the charging screen image disappears.
The charging screen image once finally no longer may not show up again until full power off/on (holding power button > 10 seconds or full battery discharge). Unplugging and plugging back in does nothing except making the device look bricked if there's too much light shining on it.
Device may not automatically leave the above state under a specific situation(s). May still need manual full power off/on.
Guessing 10 seconds could also be something else during the early/late boot process or other. The light changing color though should indicate that something is indeed happening.
Light should stay green during the boot process if its completely and fully no questions asked 100%. If you go based on that than yours doesn't appear to be completely fully charged which should either mean its turning on and using battery or not charging correctly.
The light turning off is curious. The device could be shutting off. If light comes back on a moment later then the device has rebooted. if the light stays off = n/a.
If its booting into recovery then the device would be available via adb. At that point it could be further evaluated.
On the off chance the screen was damaged it should boot and usb should be available via computer as well as adb.
If not then its probably toast unless its simply not getting a good enough current causing mislead battery stats and/or not enough energy to get to charging screen (bad wall power adapter in use, damaged power cable - though could be bad battery, defect, damage or whatever). OR there's some major error on behalf of the user happening (think should have tried that in the morning not while 1/2 asleep or came home from long trip and forget how that works).
Maybe the only other things are the emmc brick bug, was left sitting in the sun or heat or ocean air or other physical damage/defect even to the power port as well.
Or maybe it was mad that you left it. Shouldn't have hurt its feelings you know. At least its not crying battery acid on you.
That should just about cover everything except for the things not mentioned. Since its your device, you decide what happened.
Its complicated so anyone see any improvements, clarifications, or mistakes? Please put it in a post.

Bumping this thread to make it aware that there is a real answer. I have been able to duplicate this problem and rather easily too.
The problem is indeed from bad power. The device isn't receiving the correct amount of power needed to charge and start from a fully discharged battery.
To safely* duplicate this you can use a usb extension that isn't fully connected to the nook power cable. You may need to fully connect it first then slowly disconnect/connect till the light turns green when it should actually be charging. It won't actually charge in this state, or if it is, its very little and the battery percentage will continue to drop.
Leave the cable as is and unplugged. After the tablet is fully discharged, connect the usb cable. The light will change through the modes and turn off. The device will not turn on.
There are probably other ways to cause the problem like for instance a portable usb battery that doesn't put out enough juice (not the orange kind). Etc.

Bumping this thread to make it aware that there is a real answer. I have been able to duplicate this problem and rather easily too.
The problem is indeed from bad power. The device isn't receiving the correct amount of power needed to charge and start from a fully discharged battery.
To safely* duplicate this you can use a usb extension that isn't fully connected to the nook power cable. You may need to fully connect it first then slowly disconnect/connect till the light turns green when it should actually be charging.

I actually ended up fixing it yesterday!! I haven't touched it in about 3 months, and I was planning on just throwing it out getting rid of it some how. For the heck of it, I decided to plug it in, assuming that it was gonna go through the same process. But this time it went from green to amber, but it never went off. So I pressed the power button and the battery icon appeared. This was a really good sign. So I left plugged in for about 5 to 10 minutes then tried to power on.:fingers-crossed: As soon as I saw that '' Nook" boot up screen, my heart stopped. It booted up perfectly and I almost blew up from excitement :victory:. So I then flashed the stock firmware back onto it, so this would never happen again.
I guess the battery had to be completely depleted or just had to cool down. Idk but either way this was one heck of a miracle
So I recommend for anyone having this problem to just leave it off and don't mess with it. I wouldn't say for 3 months like I did but maybe test it each week or wait a month if you have good patience

Wow. Man, that's awesome! Glad you posted that update on it. Thought if you had posted an update it would be the opposite as in trashed it
Actually, I guess only you could answer if you had also moved/unplugged the power cable from the wall adapter or put it into a different wall adapter, etc. Thinking there could have been a difference there.
These modern day devices are so finicky, guess anything is possible. Like you say, maybe sitting without power is another answer.

From some experimentation I have etermined that your power adapter (that plugs into the outlet) is the issue. It does not like to be leaft plugged in indefinately. It will continually use power even when the nook is not plugged in.
Also, if you use a differnt adapter you will have the same problem unless it is also of the exact same voltage and amps.
