Screen On While Charging... - Nexus One Q&A, Help & Troubleshooting

option under the Music Player app doesn't work?
Keeps turning off the screen whether it's plugged into a car charger or a home charger.

have you tried:
settings->applications->development->stay awake ?

I thought using the option under the Music app would only keep the screen awake while playing music...like while in a car and plugged it. I don't always want to keep the screen on while plugged in at home...like at night.

You just hit the power button and the screen turns off (not the device). ; )

Aaaah! So simple...yet... Thanks! I guess I'll use that work around.

[Q] Charging when device is off...

Hi everybody!
First night with my new HD7....
As usual I turn off the device to charge during night, but when you plug its turn on again!
So... is it possible to recharge the HD7 when device is off?
Thank you!
I just got my HD7 home today and am experiencing the same thing.

Did you guys really turn it off... or just put it to sleep ? you have to really press hard to turn it off which gets a bit annoying sometimes.
Besides I dont turn my phone off.. just charge it overnight and it last me more than 12 hours a day with browsing, music and video and emails
It said "Goodbye". So I believe I turned it off.

Discussed already in the HD7 forum but I didn't check later to see if it's just HD7/HTC devices or all WP7 devices.
If it's all WP7 devices then it could be a feature to keep it on for wireless Zune synching. Zune will only wirelessly sync if a device is plugged in and charged >50%
hadn't noticed that before (don't really turn my phones off).
Maybe you could put it into airplane mode instead.
At the moment it isn't possible to charge the device while off as the default action is to sync wirelessly with Zune after 15 minutes of it being plugged in.
Like nrfitchet said, if you're worried about the radio waves next to you while you sleep or something then you could try Airplane mode.

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.

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?
Sent from my MOTWX435KT using Tapatalk
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..

Tasker In-Car power issue

I have built a Nexus 7 into my car and I have a small issue.
I need a tasker profile:
When I turn the car on, the screen turns on and music plays.
When i turn the car off, the music stops and the screen turns off. (along with other stuff)
I have created a "test" version of all this so when I connect a power cable (i.e when charging) it turns the screen on and plays music.
When I disconnect the USB (i.e. stops charging) the screen goes off, music stops, bluetooth off etc and all this works fine.
However, the USB will always be connected with power coming through so I cannot use this option. I need another way to detect if the car is on and when it turns off so I can run the correct tasks.
One option i thought of is buy a wireless charger and build it into the car. When my phone is placed on the charger, send a text message to the tablet to turn it on, and when i turn the car off the charging will stop, then the phone will send a text to the tablet to turn the screen off etc.
However after purchasing the wireless charger, i realised everytime i get a call or take my phone of the charger for whatever reason, the screen will go off and music will stop, so this isnt an option either.
So the question is, what can i do so tasker can detect that the car is on or off so the nexus can perform the tasks?
Hope that makes sense

You do realize that you really have two problems, right? The Nexus 7 will not know when the car is started, or stopped. Unless you can disconnect the power, manually etc.. If you can do that, you can send a command in fastboot to force the N7 to power up when power is connected, otherwise you'd have to boot it up manually.
You could unplug the USB charger.. Or have the tablet turn off after N hours of inactivity, although how do you detect "new" activity if there's no change when the car is started.
If your car has bluetooth, you could detect that as the "turn off" task perhaps, but turning on is probably your bigger issue.
Will the wireless charger idea work?

No idea what you mean by wireless charger (2012 model has no wireless charging), or how you'd control it with the phone. And unless your tablet is a 3g one, I don't know how you'd directly communicate with it either.
I just put my phone back to stock so I had to uninstall Tasker, however your tablet does not pull power once the car is off correct? I had a power based one as well, I remember testing it with a surge protector. I could leave the USB connected but flip the surge protector on and off (to mimic power to the phone being halted). To my knowledge when the car is off your USB shouldn't be drawing power therefore you could run the profile off that. Export the profile and post here. I'd like to help test it.

My last four cars (current and previous of wife and my cars) the lighter plug stays powered when the engine is off.
I think it's getting increasingly common for the plugs to stay powered. So there's no way for the tablet to know the car is off unless the car has bluetooth and you can look for that.

I have actually found the exact opposite to me true. My wife's 2014 Pilot goes off as well as my 2012 Veloster whereas my 2001 Sable and her 2007 Passat left them on. I'm not sure if you can resolve your issue then. I'll keep looking into it. You could trigger it based on speed I think

I suppose that could work.. Find out the speed for several periods in a row, if it's zero, assume it's time to shut down. But that'd mean it's playing music etc during that period etc.
IMO bluetooth, or a plug he can turn off, is really the only way if his USB is powered up all of the time.
Also remember, he has no way to know when to power UP either. I still maintain that's the bigger problem, especially if it's a fixed install and he can't poke the power button
At the moment, its connected so when the car turns on, the USB is powered up and when the car turns off, the power in the USB stops. So at the moment, my tasker profile works on "when charging" do Task A, when not charging do Task B. And it all works fine at the moment.
However I am having issues with charging, (The device is not charging fast enough when turned on and the battery drains over a couple of days) so i planned to keep it always charging, so the power in the USB will always be there regardless of if the car is on or off. So i cant use the "when charging" on tasker anymore. So i needed a new way to it to figure out when i got in the car.
Here are my ideas:
1. Have a wireless charger in my car for my phone. (Not the tablet). When i get in the car, i could put my phone on the charger, have the phone send a text to the tablet to turn it on. When i remove the phone from the charger, send a text to the tablet to turn it off. Simples
2. Connect a wifi router in the boot or something and have it start up only when the car starts, and turn off with the car. It doesn't have to be connected to the internet, it just needs to power up. Then i can do a 'When wifi near' on tasker to see if the car is off or on, and turn the screen off accordingly.
3. Connect the tablet to my phones bluetooth. Whenever i get in the car, they will connect and the tablet will power on. when i leave the car, it will power off. (Not the best option since it will stay on even if i am near the car)
4. Similar to option 1, but have a nfc sticker in the car. when i swipe my phone on it, it communicates with the tablet and turns it on, n then off when required. but i dont want to do this since i know i am going to forget to turn it off one day.
I don't really want to do the speed option, since i want it to turn on as soon as i enter the car, not when i start driving, and i want to be able to park up and use it when i need to put an addess in the sat nav etc.

If your charger isn't charging fast enough, you're using a crappy charger or one that isn't designed for Android. If your car has a built-in USB port, those are usually super slow, maybe 500mA, most less.
Anyway, glad to hear that your power follows the car state, that makes it all simple.

I've tried about 20 different chargers, up to 2.5amps. The problem isnt the charger. The problem is i dont drive the car long enough to give it time to charge. So if i drive the car for about half an hour a day, for the other 23.5 hours, its on standby. so the battery is always going to go less. So thats why I plan to connect the charger directly to the battery so it will always be charging.

Oh, I thought you had the tablet turning off when the car went off. If I were you, I'd set up a profile that turns off the tablet if it hasn't had power in a few hours, pretty simple to do. On Power, set a time var, every so often check that time var to see if it exceeds your threshold, and power down if so.
If you don't have much installed, it should be a fairly quick power-up, especially the plug goes hot when you start the car.
BTW I hope you're considering cold and heat if you're leaving the tablet in the car. Leaving it in the heat all summer will will the battery.
You can use Timur's kernel, it senses power to turn N7 on or deep sleep it.
Also charges N7 while using OTG.
It;s designed for car install.

I agree, you need to get at least a 2A charger for your car. My wife would watch Netflix on long drives and my car USB port or the normal USB charger I got for the cigarette lighter worked until I up'd it to a 2A charger. I can have screen on for hours while streaming video and still fully charge the tablet in a reasonable amount of time.

Screen Wake When Plugged In

My phone screen turns on when I plug in the charge cable or put it on the wireless charger. Is there a way to disable this?

Per chance do you have stay awake enabled in developer options?
There is no native way to avoid this behaviour, but you can somewhat manage it via an app called Snoozy charger in playstore
I'm just curious... Why are you bothered by the 5 seconds of screen on when you plug in the charger ? It just gives you an indication that charging has started, 5 seconds, and then it turns off.
