I've never heard of CM7 causing something like that- though I assume you mean you have your evo on but can't press it to bring up the power menu. If you mean the power button won't turn the screen on, check to see if the buttons are at least lighting up. If they do, that's a backlight issue caused by the CM7 kernel, not the power button. Try to turn the screen on and off a few times and the backlight should eventually come on. Then, in cyanogen settings, turn the screen-on animation off- that solved the backlight issue for me.
Otherwise, try pulling the battery to turn it off, then plug it back in, if it doesn't turn on at all when you hit the power button from there, that's a hardware issue and it's time to take it in to get fixed.

Sounds like a bad power button. Lucky for you cm7 just added the ability to wake the phone from the volume keys.

There is a widget as well that you can apply that will put the phone to sleep for you.

You dont need to pull the battery!

I see so many threads where people say "I had to pull the battery".
This is not necessary just hold down the power button for over 10 seconds and your phone will reboot.
Hope this helps some of you.

I Tried it earlier also but I think I didn't pressed the button for 10 secs. Now when I read your post I re tried and waited long and phone rebooted. Thankxx man.

Power + Home always works for me, seems to take less than 10 seconds too.

Sometime, u really need to pull the battery out , let say, for example, when ur phone boot in a loop and just showing the samsung bootscreen....
But I agree with u, most problem that people share here doesnt require to pull the battery out

Actually you can usually enter download or recovery mode while the phone is looping without even touching power button. The power button part of the sequence is just to turn on the phone. Just hold home and vol up/down and the phone will enter recovery/download the next time it reboots. I have only had to pull the battery once it was when something goofed in download mode.

Didn't know this trick actually. Will come in handy. Thanks

You made my day, I was pulling the battery once in a while when my phone froze and I'm happy to know I don't have to.

Surprisingly, not many people know this. It certainly saves some wear and tear on your battery cover. I didn't know it for a good few months of owning my device. I hope a ton of people read this!

Apparently when I applied a bit of Brain then I discovered that u don't need to switch your phone off compeltely for going into recovery mode.
Just try this- press and hold power button for 5 secs or so and then press volume up and home button. Keep all of them pressed and you will enter into recovery . It isn't such a gr8 find, its the same as what u do when u turn your phone off and go to recovery but its more easy.

Yep, I've been doing that for awhile now. Both are extremely helpful. Everyone should know about this!

Holding down the power button for a long time doesn't always work.
Useless thread.

Really? Or are your little fingers are too weak to press the power button for even 10 secs.

I beg to differ. Rebooting to fix issues doesn't work all the time either, is it useless to suggest that too?
I've had my galaxy s since launch, and it has never failed to reboot by holding the power button. So for whatever special cases where it may not work, there are literally hundreds that will. This fact alone makes this thread anything but useless. Besides, the battery cover is not very durable, anything that helps to avoid removing it is good, even if just occasionally.

Does the home button actually make a difference or is it equal to holding the power button while quoting Shakespeare?

as far as I may look, no one suggested that you have too small hands to pull out the cover and remove battery... yet

Well for those who have a hard cover on the back of their phone, power button option is better, Battery pull option is always their.

CORRECTION. Proper post should look like: as far as I may look, no one suggested that you have too small hands to pull out the hard cover, then back cover and remove battery... yet

[Q] Does the N4 come with a default screen capture?

Hey all multiple times I have wanted to take screen shots and I was wondering does the nexus 4 come with a default screen capture or do I need to download one of the apps to do this. I know some androids are starting to come with this feature default finally such as the S3.
Also can anyone give me a reason as to why screen captures have not been implemented by Google. Legal issues with apple? No reason?
Thanks all

Press power and volume down together.

I have tried this many times and so far it has never worked. Maybe I am just challenged

Yep power and volume down and hold it for a few seconds together then it will take a screen shot

That button combo (pwr + vol-down) doesn't work for me while the desktop is showing, but it works with an app in the foreground. Even works in the INFO screen.

Thanks guy helped me plenty! Just didn't hold down the buttons down long enough

I can take a screenshot anywhere, just have to hold both buttons for a couple seconds. Even works on the lock screen!

Ya u gotta hold it til it takes the shot

Are you doing it simultaneously? Give it like a second or two before releasing

press the power button first and the the volume down button...and then wait for your INSTANT WIN!!

or you can just get an app that will do it for you

no point in installing useless apps that consume memory when its in the OS natively. its not that difficult to press two buttons at the same time and getting it right. once you do it once or twice, you'd get the hang of it and all is good.
either that or flash a custom rom and u can add the screenshot button on your long press power button menu.

It works for everyone. All you have to do is push them at the same time. Power + volume down. Hold for like three seconds. If it doesn't work hold for five seconds.

It's very tricky. I said the same thing when I was doing it on my galaxy Nexus but got the hang of it.
Place your hand on the volume down and power button before pressing them and then hold them both at the same time until your phone makes a screen shot animation.
I will give Samsung this though the slide to screen shot is very intuitive on the touch wiz platform.

Oh so that's why. Since the new diztronics cover the buttons, it's probably not being pressed correctly.

Tell that to the people who had difficulties
It is tricky at the beginning but like I said over again and again, once you know how to do it. It's not tricky and is very easy to do. I understand depending what case they have on it may be trickier because the case covers the buttons that all of us overlooked

Screen shot working on Nexus 4 after trying this!!!!
Press Volume down button and power button until phone get restarted. then you able to take screen shots.
It worked for me.

Try first powering off your phone. I had a little issue and i could not get the shutting down menu after several attempts, the phone restarted it self and after it was up, I was able to take screenshots without any difficulties.

My nexus had the same problem... and yes, I know how to take screenshots...
But by doing this the problem was solved... thanx man!

Hypothetical question..

Hey guys..
I've done a lot of rooting and flashing and all that on many phones... Just kind of curious because sometimes I end up in a boot loop in the past.. What would I do if that happened on my nexus 4 or 7??
There is obviously no battery pull.......
This is the only thing holding me back at the moment Lol...

I thought all you had to do was hold down the power button for 10 seconds or so and it would shut down. Don't think volume up is necessary.

Correct. A lot of the time I just do volume up as well so I can boot straight into recovery instead of just powering off.

Power + vol down will get you into bootloader so you can use fastboot.
