[Q] N7 only detects power when diplay is on??? - Nexus 7 Q&A, Help & Troubleshooting

Hello! I am running cyanogenmod and Timur Rom on 2012 N7. I have tasker to detect power on and power off but here's my trouble..
The N7 will only detect power when the display is on!?!?!?!
If the display is turned off or times out or is locked and I give it power, the display doesnt turn back on automatically. I turn it on manually with the lock button on the side and the battery shows no charge coming through.
With the display still on, i unplug and plug the power back in and it works fine!
I tested it on the PC. PC detects the N7 fine and sees the HDD. Even with the display off, the PC will detect the N7 and I can explore folders but the N7 still receives no power until I manually turn the screen on and unplug and plug the charger back in!
This is preventing me from doing the car dash install because I cannot depend on the N7 to turn on display automatically because it does not detect power with screen off. Only with screen on!
I have went through all settings a million times, tried every 101 troubleshooting step, and I cannot figure it out.
Please, please, please help me figure this out. It's driving me crazy! :cyclops:

[Q] POWER RESET or UNKNOWN UPLOAD MODE

Anyone having boot problems?
Waiting the case, i have put my tab in his box moving from a place to another, when i took it i saw a green andoid image with the message "POWER RESET or UNKNOWN UPLOAD MODE".
Now it is blocked in this message state. Can't turn off, reboot ...use it...
Anyone know the way to reboot (key combination)? if galaxy tab has a recovery system? or something in order to resolve this problem?
Just to know, no root attempts, only some application normal installed from the market...
hi, i think if you press the power button and leave it pressed, it will reboot.
after the battery charge finished and the recharged all work fine...
i think the "block state" has been caused from the home+volume keys that probably were were pressed in the box..
it would be usefull to know these key-press effects
They are standard android combos. Google is your friend.
I stumbled across this screen while my Samsung SGH-I897 (Captivate) was powered down, hooked up to my PC using the USB cable and the battery was half way charged. I held down both the power and volume up buttons for a few seconds and got to this screen before the unit attempted to boot. It remained there until I held down the same key sequence for about 5-7 seconds. It's now back to a powered off state, still hooked up to my PC via the USB cable, and the display has the standard large battery icon showing it at about 50% charged. Leaving the Captivate idle will continue to charge my phone via USB (abeit slower than having it attached to the power adapter) and the screen shuts itself off. It practically looks like it's fully off or fully dead like this, but it's not.

Questions about charging the NookColor.

I dunno if this phenomena is normal with the NC, or if it's happening ONLY in my NC.
I've noticed that whenever my NC's battery is low*, you cannot turn it on anymore. That's all well and good, because I would like to keep it turned off while it's being charged. I reckon it'll make it faster to charge because it doesn't use that much power in that state.
The problem is: IT DOESN'T STAY THAT WAY.
In my case, as soon as the NC's battery level reaches 9%, it AUTOMATICALLY TURNS ON. And whenever I try to turn it off again WHILE THE USB CABLE CHARGER IS PLUGGED IN, it AUTOMATICALLY TURNS BACK ON AGAIN, which is extremely annoying since I don't typically use it while it's being charged. For me it wastes a lot of time because it would've been faster to charge it while it's turned off.
Anyone knows who can help me out on this?
1st Question: I want to be able to charge my NC while it's turned off. Is it possible?
2nd Question:
Is there a way to override the rule where it needs to have at least 15% power before you can turn it on?
I think I read in one of your posts you're using CM7... If that's the case... after your nook is connected and charging.... or after it turns itself back on....
Press and hold power until the power menu comes up
Select Power Off in the menu
It won't power back on automatically when you shut it down that way.
Are you sure that pressing the power button doesn't turn off the screen?
Cause I think that mine works this way while charging.
Unleashed from Nook Color on Cm7 Nightly 162 @1.200Mhz
I get the screen/charge thing too on nightly 150. Plug it in, turn screen off, look back in a few minutes, screen is on! I like to watch a video in bed while I drift off with it on slow charge but the screen is still on in the morning.
I was planning to use Tasker to fix this but haven't got very far yet.
I turn mine off all the time when I am charging. The only time it turns back on is if there is a power interruption.
I've seen many threads/posts talking about charging NC.
My case:
Once plugging for charging, it turns ON. I (or we) have to turn the screen off. Note: just turn the SCREEN off, not turn the NOOKcolor off.
I've had the same 'nook turning on when charging' on all roms tried - CM7, MIUI and MN Nook stock - and always wondered why??
In any event, i too also just turn the screen off.
cheers,

I always turn it completely off as it charges faster. There is no harm in doing so.

You can do that but it just takes longer time to get ready after you unplug the charge, with screen off, all you need is light press the N or the power button.
Additionally, don't know about CM7 but with stock OS, B&N clearly indicate that we need to turn screen off, NOT the NC off when charging.

Because there's no way to turn it off and it not reboot with power using stock AOS... it always behaves exactly like CM7 does if you hold the power button to turn it off... it reboots if power is connected... with CM7 you can select the power off option in the power long press menu and it will stay off.

Device automatically turn ON.

Hi everyone,
I bought a Nexus 7 32GB last weekend and I think that it might be defective. When I turn OFF the device and than plug it in the wall, the device automatically turn ON on its own (every time). If I plug the cable and than turn OFF the device, I can see the battery sign. After a few second, the screen turns OFF but when I turn back ON the device, it didn't charge at all.
Is there something wrong with it? Is it fixable? Should I return it and get a new one?
When the device is ON, I can plug it and it will charge normally.

[Q] (Q) htc windows phone 8s won't start or charge

Last week I was on my htc windows phone 8s and my applications weren't working so I decided to turn him off and on so he would work (I did this a few times before and after that everything was working) but this time he didn't turn on. I put him on a charger but there was no response nor the LED light. I connected him to the laptop using usb cable but the laptop didn't recognize it but i could hear sound of connection and also in device manager I could see some files. I left him that night on the charger and in the morning everything was the same. It has been a week and still nothing; few times when I put him on a charger a short LED light appeared and the phones vibrates and then nothing. I tried pressing the volume buttons but he would only vibrate one time and then again nothing. Please,please tell me something can be done
