Twice in the last 4 days now I have come to my phone pressed the power button to wake up my phone and nothing happens. Both times I have had to do a hardware restart with power and volume up pressed.
It has happened after it has been fully charged when I go to use it first thing in the morning. Probably not an alarm as it happened on Saturday first and there was no alarm set.
I know the phone was still on because on the second occasion the notification LED was not flashing but got no response.
My alarm never went off. I am fortunate that after the first time I questioned the reliability of the N4 and set my N7 as a second alarm.
Only App I have recently installed is Chrome Beta, uninstalled to be on the safe side.
Has anyone else had this issue, or got any idea what could be causing it!?
Fingers crossed 4.2.2 is real and it has fixes for this stuff!!!
Try doing a factory reset. Are you rooted? What kernel are you using?

Just stock factory. Very few apps installed as I don't use that many (browser for most things).
Could try factory reset...
while your screen is on and in the home screen, long press power button until you get presented with shut-down options, then long press the "power off" button until you're presented with "reboot to safe mode"
use your phone in safe mode for a day or two and see if the problem repeats itself.
if the problem does not repeat itself, that means an app you've installed has changed something.and is the cause of your problem.
Try press the volume button before press the power button to wake it up. I also encounter this problem occasionally and manage to turn the screen on with the volume down then power

I'm running a completely stock phone and unrooted. For some reason my power button stopped working properly yesterday. When I press it the screen won't turn off anymore. The only way to turn it off is to set the screen time out to a shorter interval. The only thing I can think of that I did before it stopped working was trying to take a screenshot by pressing the hardware back button and home key several times like it said in that thread. I also tried doing it with the backspace button and home button. I wonder if I hit some weird keyboard combo that disabled the power button screen shutoff. It will still give me th "power off/silent/airplane" options if I do a long press.

Okay, I fixed it. I don't know what originally caused the problem, but I manually updated all the system options: firmware, profile, PRL, and Android, even though there were no actual updates to download. Pressed the power button and it's back to normal.
Whew...I can change my timeout back to 30 minutes.
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.
Hi,
after unlocking and rooting my Nexus 4 I flashed the franco-kernel. I did these steps with the ToolKit. But now when I start my phone I can press the power button once and it offers me to shut it down. After that there is no reaction when pressing the power button. I tried to reset the Nexus but I still get the same error. Can anyone help? Thanks!
EDIT: My nexus just turned off the screen and I was able to reactive it by pushing the powerbutton. What works all the time is shutting down the phone by long pressing.
From your initial post it sounds like it might be sticking..

I don't think that it's hardware related. It might be a software issue. Sometimes the screen stays on for ever unless I open an app and close it again. It seems the phone doesn't know what to do when the button is pressed.
EDIT: When connected to PC I can use the button only to power off the phone. I can't wake it...weird
Long pressing the power button does nothing. The power menu does not come up, and as soon as I stop pressing it the screen turns off( the long press registers as a quick press so waking the screen on/ turning off is fine).
Any ideas what i can do ? Maybe force stop a certain service that would refresh the whole UI or something. My battery is at 9% now so I can wait till the battery dies and reboot it after. But im afraid it wont turn on if it was a hardware fault ;/
EDIT:
Solved. Had to do a hard reboot for it to work(holding down the power button for 10 second). Now it works fine, and i feel stupid . Lock please.

Hi all, I am having a very strange problem with the power button on my Nexus 7. The problem is that sometimes when I press the button the screen does not come on and I have to press it several times or I have to press it very hard to get the screen to come on. Pressing the power button to turn the screen off does not cause any problems though. The fact that the screen would turn off okay but not turn on made me think it was a software problem, but doing a factory reset or switching ROMs didn't help so maybe it is a hardware problem. It also happens in recovery mode (TWRP 2.6). I can turn the screen off and on rapidly with the power button with no problems, but once the screen is off for more than a few seconds it's hard to get it to come back on. I thought maybe it was sticking or something, but again I never have any problems turning the screen off. I bought the device used several months ago, but it was originally purchased over a year ago so I don't think warranty will cover it. I only noticed it start to do this in the past couple of weeks or so. Any suggestions on how to fix it? Here's what I tried:
1) Factory reset - No change after the factory reset
2) Flashing a different ROM. I was running stock rooted 4.3, also tried SmoothROM and cyanogenmod but get the same problems. Also have the same problem in recovery mode.
3) Opening the back case - didn't notice any physical problems with the button. Even when I press the little round metal button on the inside of the device that corresponds to the power button I get the same problem. It makes the normal clicking noise but nothing happens unless I press very hard.
Anyways, it's not the end of the world I just have to press the button very hard to get it to wake, but it is a bit annoying and would be nice to be able to fix it.
Update: Ok, this is strange, but I just did another factory reset and it seems to be better now. I'll keep you posted in case the problem returns.
Real strange!
