Screen wont turn off when plugged in - CM

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.

[Q] Touchpad won't boot

I cannot get my sisters TP to boot. I guess she let it die completely, so now when I plug it in, all I get is the home button to blink back and forth. If I try to turn it on, I get the red battery with a lighting bolt icon, then a white plug icon, and when I plug it in from there I get the "To reliably charge" message. I don't have the original ac adapter or cable because she lost it. I have already reflashed the A6 firmware. Also, if I leave it plugged it with the home button flashing, after about 20 minutes or so, the flashing stops for a few seconds, then starts for a few seconds, then stops again and so on and so forth. Is there anything else I should try? Or is this thing dead?

See if you can get an OEM cable or a Touchstone.

Leave it charging for a long time, 24 hrs +, it should charge.
Good luck.

original charger

You need to find an original charger or maybe a compare able 2amp Carter will work. A standard phone charger or USB port on your computer is not powerful enough to charge it.

Check amazon it shouldn't cost more than $10

I have another tablet charging block that is 5.0v and 2 amps, but when I use that all it does is make the home button flash then stop then flash again. I left it charge on my computer overnight to try and get it to trickle charge. When I woke up the home button wasn't flashing and when I try to turn it on, the red battery comes up for a second then the white plug icon. I guess I'll see about getting an OEM cable, hopefully that works.
UPDATE: I got it into "recovery" mode? It was plugged into my PC so I held power and vol up until my pc recognized it. But it's showing up as palm in the device manager, and no drivers seem to work for it.
UPDATE 2: My sister found her OEM charger and now it seems to be actually charging. Thanks for the help, I'll let you know if this doesn't work.

Yep, usually issues like that are because of not using the OEM Charger.

Battery dead, bricking issue
I have had several charging issues with my Touchpad. I am using ClassicNerd Butta OS. IF I am using the Android OS (Butta) and I turn off the Touchpad and then plug it in to charge it will restart the Butta OS. When this happens the Touchpad discharges instead of charging. So, when I come back later the Touchpad is dead and it takes a lot of messing around to get it going again. To prevent this I always turn off the Touchpad when I am using the Butta OS but I don't immediately attach the charging cable. Instead, I wait a bit. Then when I plug in the charging cable I immediately switch to the WebOS operating system. The device seems to charge well using WebOS. When it is done charging I unplug the cable and turn the device off. Next time I restart the Touchpad I let it boot to Butta. Then when it discharges to 80% or so I start the process again as stated. Sticking with these procedures has prevented the no-charge / no-boot issue from reoccurring. I also no longer charge the Touchpad at night. Instead, I charge it in the morning or during the day and only leave it on the charger for an hour or two until it is fully charged. It is my understanding that technique should result in longer battery life and better (longer) charge in the battery.
When my Touchpad battery has gone completely dead it is a real pain to get it to charge up the battery again. When the batter is totally dead the device will not boot into any OS or allow me to even get to the boot loader program. Takes a lot of messing around to get it to start charging again. Though I have been able to, eventually, get it to boot into WebOS and start to charge. But this was not an easy process by any means.
Also, I would agree that you really need to get a stock charger with the cable for your Touchpad. Using a different charger could damage the battery in your Touchpad and/or cause the battery to charge too slowly.
Good luck!

My Hp TouchPad tablet came today and I was told when bidding that it was doing exactly the same thing as mentioned here. I have the OEM charger and cable.. I'll let you know when I can get it straightened out and I hope it is a good one.. Thanks for the info..

While on the OEM charger it booted and I selected webos for the tptb to reflash A6, but soon after it was off charger it went back to the battery icon. battery life low I guess? I selected shutdown. Let it charge over night and see what happens.
Many thanks to many members who are so helpful...

Did you get this to work?
Based on your post count, this is probably a stupid question but:
You tried charging in an outlet (not through computer), right? Any under-the-hood work makes my Bionic run hot and burn through the battery.
More technical: I read somewhere that someone upgraded to windows 8 and fastboot stopped working. Windows 7 fixed the problem (if you're saying that fastboot is the problem, not Vol - & power button recovery mode).
Were you in the process of rooting?

I am kind of having the same problem. I recenty got a droid bionic where I had to replace the LCD screen and battery since when I got it it did not have a battery with it. I got an NON-OEM extended battery and every thing was working fine for three days. In that time I was able to upgrade everyting to the latest software, fireware, and Android version (4.1.2 JB) but after those three days the phoe woould not power on. When I plugged it into my computer and tried, the white power light would just blink at me. when I unplugged it from the computer and tried it would not even come on. I thought it was the battery so I sent it back and got an OEM extended batter and a OEM dock/charger. When I got everything I plugged it all in and the screen came on with the Motorola M logo and then showed me a picture of the battery at 5%, so I let it charger over night. In the morning I pressed the power button while still plugged into the charger, the phone light up saying the battery was at 100%. So I took it off the charger and tried to power up. Nothing happened. I plugged it into my computer and the white power light came on and stayed solid but still no power-up. I just tries the Volume Up/Down power while plugged into the wall charger and I can get to the recovery screen and try the normal boot up, I get the Motorola M Logo screen, I just now tried recovery and the little Droid just showed up with its stomach with a red triangle and an ! in it and is just sittin there. and now it when back to the Motorola M Logo screen then the battery screen. Does this mean mine is bricked as well? Please some one help.

Bumping because of no help yet. I can access the recovery screen but does not seem to help any, it also has to be plugged into the wall charger for this to happen but I can not power it up whether it is plugged in or not. Please Help someone so I can get this figures out.

Alright strange thing to try, plug it into your computer, while plugged in take it the battery, give it a minute and put it back in while still plugged in.

Did as you suggest but when I took out the battery. the white light stayed on. Still could do nothing. Waited 2 minutes, put the battery back in and still nothing. All I get is the white light staying on. I unplug from the computer, the light turns off and still nothing, not even the recovery screen will boot up.

Can you get to the fast boot option by holding both volume buttons and power

As long as I keep it plugged into the wall charger I can. When I go there it says "Battery Low Cannot Program Connect USB Data Cable. But as soon as I unplug the wall charger it shuts off and I can not get back to fast boot. When I plug it into the USB cable and plug into the computer, I can not get to fast boot. I just check and it says my battery is at 100%. but when I first plug it in it says 5%.

Your gonna need to charge your battery with either an external charger or the usb charging hack before you can perform an fxz on it

M7 charges for 20 seconds then stops charging

Dear XDA,
I have a fairly annoying problem. The phone is not charging properly.
When i connect my phone to a charger it charges for roughly 20 seconds. Usually it doesnt show anyting at the start. But after a while it shows the charging icon on the display and the led starts blinking. After 20 seconds it stops doing that and after a while it shows the charging icon + blinking led again. Somehow it's in a charging loop.
I've tried different adapters. Different cables. Let it 'charge' overnight. And hook it on to a computer for a hour or so.
Sometimes i can turn my phone on but then it's on 1% and powers off emediatly. It won't charge when it's turned on.
I'm running MaximusHD 46. I have it for a while now and had no problems whatsoever.
The phone is from the Netherlands but I live now in Zanzibar. They have a different power output and the voltage is not stable. Usually i charge it when there is a stabilizer connected. But hasn't been always the case. Could that be the problem?
Thanks in advanced for your replies,
Lennard

This problem occurs all the time? I mean it's the same in all modes like when booted up and running Android, while powered off and while in recovery.
Or only when the device is powered off?
What recovery are you using ? (name and version) please :good:

I have not been able to get into recovery. Basically it's dead in the water and occasionally i can turn it on.
The recovery i use is TWRP. The version i'm not sure of (since i cannot check) but if I think it's 2.6.3.6.

Sounds like a Hardware problem either with the usb port or the battery itself.
A new usb cable may help if you've already tried that there's not much else you can do.
Some of the newer 2.8.x.x versions of TWRP have issues charging while off. But it doesn't effect charging any other time. Have you tried powering on while it's connected t an AC wall charger?

I've tried multiple usb cables and chargers . Also I tried to turn it on while connected to a wall charger, even recovery doesnt seem to work. Yesterday I still could turn it on. But today not ..

Lint? What do you mean with that? But yeah, I have cleaned the usb port from dust.
And I managed to get into recovery! I tried finding out where i could reset the battery settings... but I couldn't find it . The phone was getting hot so i think it's sort of charging in recovery mode. So i let it be in recovery mode for the charging. Let's see if that works :]

If you can get a little charge in the battery you can try the USB Host Mode reset. Power off the device and hold Volume up+Volume Down+Power. Hold all three buttons for 2mins plus. The device will appear to bootloop while your holding the buttons. That's normal. When you let go the phone should boot up normally.
Test the charging again :good:

I suppose it would be best to disconnect during the reset procedure. But I don't no for sure if it will make any difference connected or not.

[Q] HP Touchpad not charging...no charging sign

My HP Touchpad was working fine until a few days ago, my little sister was using it and she drained the battery. I plugged it into the wall socket and it started giving the drained battery/charging sign. I let it charge over night but in the morning it was still giving the same sign. Also the homescreen button had a white light blinking(to and fro). I still let it charge for 5-6 hours but still nothing. I went online to look up what was wrong and read that the cylindrical adapter has a twist-and-lock feature and this can become slightly untwisted over time and so i untwisted it and re-attached it(heard the click) and then connected the cable. But now, there is no charging sign, no blinking light, the PWR +HOME and PWR+HOME+VOL option isnt working. Any idea guys?

USB cable often faulty

The USB cable that comes with the tablet often breaks. If you're still using the original one try a different cable and leave it charging overnight. You can also hold down the Power button and click the Home key 14 times for a reboot, holding power and home usually works when the TP is not responding. Hope this helps:fingers-crossed:
