Power button - Nexus 7 Q&A, Help & Troubleshooting

Hello,
I have a strange problem with my Nexus. My power button is acting strange. Long hold brings up power menu, but:
- short press does not turn screen off
- Smart cover also does not turn screen off
- double tap to status bar does not turn screen off
- 15 seconds of timeout also does not turn screen off.
What is happening? Thank you.

So your screen will not turn off at all besides powering off the device?

Thats right.

Well i don't think the power button itself is the problem since it works to power it off and on, and since the screen wont sleep by other methods either.
Did you flash a new ROM, kernel, or other mod before this happened?

How swithc OFF my XDA mini?

Dear friend,
how do I do to put OFF completely my magician XDAmini?
Best regards
Daniele
Take the battery out?
And pushing the power button?
The power button can only put the phone is Standby. In PDA phones there is no such thing as OFF. The RAM needs power all the time. Sliding the battery cover in and out will also power off the device. Don't leave that long though, otherwise you risk losing all the information.
Hello,
I'm new so plz be patient. Ok, pressing the power button only allows us to set the device in standby mode. How do I turn off the phone (gsm) mode then? The idea is just that I want to figure out a way to reduce the power consumption as much as possible.
Thx for all coming answers..
To turn the phone itself off click on the signal strength indicator then click on 'Turn on flight mode'
This turns off the phone part of the device but leaves the pda side still functional
HTH
Alrite. But is there a way to accomplish that task with hardware buttons? Guess not, ey?
Just don't wanna pull out my stylus that often.. *g*
Press and hold the power button for several seconds. this will actually turn the device OFF.
Do the same to turn it back on.

This is not true. When you do that, the background light will be off, but the phone is still working.

You could install PocketZenPhone from here: http://zendrui.free.fr/ and then, as long as your fingers are not too fat, you can press an icon on the today screen. 8)
Cool, thx for this hint.

I don't think that the GPRS is using that much power, but to turn it off, hold the RED Phone button down for several seconds (I never timed it, I just wait for the "GPRS Connected" icon to disappear.
Your best bet for power consumption is to lower the screen brightness to it's lowest level, and set the screen backlight to go off at 30 seconds, and lastly to set the device to power down at 1 minute of inactivity.
copy this app to your magician, in a folder you want. Bind it to a hard button or make a shortcut on your Todayscreen with SPB Pocket PLus or another program.
PocketZenPhone (the tray version of it) can also be used to set the profiles via hardware buttons. This can be done with making shortcuts to the .exe with setting the specific profile. I'm using this together with MortButtons to switch between my profiles of PocketZenPhone.

Yzord; no it really does work (did you try it ?)
Yes, pressing the power button briefly just turns the screen off ; I think we all know that.
However holding the button down for several seconds will allow you to turn it off completely. = power off; no applications running; no phone or other network connections; zero power consumption, nada.

the best way to stop using magician:
charge battery to 50%
do a backup
pull out battery
pack you magician
several years later
get it out
put in battery
do a restore
charge and use it
(maybe 5% drop one year, so can put aside ten years

It will still lose some power in keeping the RAM filled, if it loses all power (goes very slowly however), all your installed programs and data will be lost. It takes a long time, but it still uses power to keep the RAM chips powered and the clock correct. Furtheremore, with the Magician it keeps the phone and alarms awake, so you can receive calls. You have to turn on flight mode manually to turn the radio off. Also you have to turn off all alarms to prevent your device from waking up. Your method is more like the one used on the Wizard, where holding the power button for 5 seconds really turns everything off and when pressing and holding again makes the Wizard start up again (with boot screen and all).

Also thought of this when I first got my xda mini. Now, after some reading here in the forums, I just switched my xda mini to flight mode before I go to sleep. It turns off the phone. Hope this helps.

screen doesn't turn on by screen tap?

Hi All,
My Wizard is set to turn the screen off after a minute of inactivity.
To get it back on, I have to press the power button.
I've checked in backlight and power settings and have it set to allow a screen tap to turn the backlight on, but it's not working - well, if the backlight's off but the screen's on it works ok, but I want a tap to turn the screen and the backlight on together. At the moment I have to press the power button, which upsets Pocket Player MP3 playback...or I can press a hardware button, but again, this tends to interrupt playback of music as all the buttons are mapped to something.
Seems a simple request, am I missing anything? This is under the Mr Clean ROM, if it makes a difference.

Once the screen goes off, the phone is "sleeping". The only way I know of to turn it on at this point is to tap the power button. To do what you want would be turn turn off the screen going into sleep mode, but that will come at the expense of your battery life. Start>Settings>Power>Advanced then uncheck the Turn off device under On Battery Power.
device lock(s)
A halfway solution, you could turn the screen off using the device lock app, which includes screen off. Then when you press the power button it only effects the screen and not anything which is running. The second one is very good for listening to music with, assuming you volume control button isn't broken like mine

Shut Down Cab?

Downloaded and installed the Shut Down Cab on my Wing. The three options are:
1. Light Off
2. Shut Down (Does not Power Off, only turns off screen?)
3. Soft Reset
My question is: Should Shut Down turn the Power Off? If not, what is the purpose of this compare to Light Off?
Thanks
Press any key if you press Lights off. You'll see that your phone is still on but just with the lights off.
Shutdown is like when you press your power button on the top.
Soft reset, well... speaks for itself.

Thank you. Apparently Shutdown and Lights off do the same thing for me as I can touch any key after using either one and the phone works as if it were Lights off.
Maybe I don't see the purpose of them as being separate functions.
Check "keyboard lock" (more or less.. my wing rom is in spanish) under configuration - system and make sure it's set to "block all buttons except power button" if not, every button will power on your device after shutdown, making it look like turning the lights on.
Hope works for you.

Yes, that is correct. That is why I said that both options are doing the same thing. I would have thought that one would Power Off.
Again, thank you for your input. I do appreciate it.

Different ways of turning off screen?

I don't usually lock my phone when it's on standby. I usually just turn off the screen to save battery. I do that by pressing the red power button. Just wondering if there's an app that I can use to turn off the screen instead of pressing the button all the time?
Thanks.

Power option, you can set a time for the screen to go off.

[Q] Any way to turn the screen on via the volume rocker?

So I think there might be something wrong with the power button, when it does work it has a 5 second lag between pressing it and when the lock screen pops up. However, there have been several times where I'm going to bring it out of sleep mode and it doesn't wake up - so I press and hold the power button for a few seconds and nothing. When I press it again it vibrates and boots up normally. So what I think is happening is I'm actually turning it off, thinking that it's having issues with the SOD, and then turning it back on again. But no matter how many times I just simply press the power button it still won't bring up the lock screen out of sleep. So is there some way I can turn it on via the volume rocker?
Thanks in advanced.

That is the sleep of death. No on the volume without special programming.
Well, the only thing that made me think it was otherwise was the battery stats - it shows that the tablet has been awake the whole time it's been in SOD...

That is what I have found, it is still running. That is why you have to monkey with the power button, the first long press shuts it off even tho it looks to be off. After it is shut down, then it will turn back on. Their are some ics roms that this is fixed in. I used to have the sod, but the rom I am using don't have that problem and I have had that problem with all roms, sept ics.
