Lg will cover it for free if its under warranty. I just had that happen to me not too long ago. I was without it for about a week and a half.

Same thing started happening to me today
The exact same problem started happening to me today. My N5 was one of the first-day order models, and the power button is a little loose, so I guess it must have gotten faulty over time.

Going to RMA it tomorrow. It seems like this issue is popping up everywhere all of the sudden.

This happened the me a few months ago. Google RMAed o e to me and overnighted a replacement. The weird thing is they sent me a label to return the phone to LG, then a day later they said not to use that label but use a new one and the new one was labeled to Google in Mountain View. I'm guessing it is happening a lot and Google wanted to look at it themselves.

Also I fixed mind with a couple magnets from a hard drive I took apart. I just kept playing with it around the power button, then having the phone sideways with the power button sitting on top of the magnet I was able to get it to boot up and flash back to stock, etc, then kept playing with it and problem went away. I emailed Google that I did that and sent the phone back anyways.

After trying all suggestions.
Only the above magnet trickery WORKED.

Magnet held at the power switch for 1second did the trick!!!!!

The only thing that gave any hope before this trick was a constant tapping at the back of the phone behind the power switch - this was not fool proof and allowed the phone to continue booting but as soon as you stop tapping it would reboot again.

I even disassembled the device to assess the switch on the motherboard, playing around gave no success with this attempt.
(the switch its soldering and the board itself all looked healthy.)

Given the success with the magnet there is strong reason to believe the 2 metal contacts WITHIN the power switch itself were indeed stuck together -
HENCE whenever you attempt to power on (without USB connected) it wouldn't power up BECAUSE the 2 contacts were already touching (hence the device wouldn't distinguish the power button being pressed.)

However when inserting the USB to the phone, the device as you'd expect TURNS ON automatically without needing to press the power button... BUT because the 2 contacts within the power switch were constantly touching this would induce a undesired Power Button Press (albeit without actually pressing the power button.)

This now makes sense that when applying a strong magnet in and around the Power Switch - releases the 2 contacts within the switch & therefore deems the power switch usable once again (for how long the switch continues to behave is unknown - perhaps we need to keep a magnet on our key-ring at all times haha.)

Great diagnosis @nxt.

Saved my girlfriend and I a lot of hassle.

Hope this helps anyone in the same predicament.

This is NOT s/w related - most definitely h/w related.

Thank you so much for this solution!! I tried to use Magnet but it failed (maybe because my Magnet is not powerful)..
And then I kept tapping at the back of the phone, it can finally boot up!!! I tried to keep tapping for almost half an hour and seems it's return to normal now...
But I don't know when it would be broken again...But anyway...thanks for the solution!!!

Having bought the phone from a dealer, yesterday he requested me to take a video of what's happening (the constant restarting). At this point of time, I have already tried boot loader as well as factory restore.

As I was recording the phone, it began to show glimpses of improvement (managing to start up to home screen) when not being plugged in with charger. With a charger, it's worst and only reboots up to the Google screen (not reaching the 4 coloured orbs). However the problem eventually came back.

I left it beside my laptop and tried turning it on here and then. Still the same.

10minutes ago I got crazy and tried turning it on while recording it. This time it worked!
I recorded it for 7mins and have been using it for 15+ mins now. I have no idea if the problem is gonna come back but that's my story.

It could be a moisture issue. Considering that I live in Singapore, and it's a humid country.

My Nexus 5 had the same issue as the video being shown above. It keeps rebooting at the Nexus 5 logo, I've also tried plugging in to the charger same thing happens and it reboots every 5 seconds, only gets to the colored ball every once in a while. Same thing happens when i try to get into fastboot mode.

I've always had a case for my Nexus 5 since i got my hands on it. So after taking off the casing i noticed there was moisture caught between my casing and the power button area. I thought maybe i might have used the phone while my hands were wet, so i left it in front of my fan, while checking the forum for solutions. Came back an hour later to try again, i plugged in my phone to the charger, and it worked!! My baby's alive again!!
Managed to solve it within an hour.

Though it's working fine again since less than an hour ago. I might be wrong about the moisture issue, maybe it's luck, but that's my take at it.
You can try using a hair dryer or something, it'll work better. I'll keep this post updated if it actually solved the issue. Good luck mates.
