Power Button not working in Arch - no events of power button

First of all Hello to everybody, I'm a newbie here and just started using Arch Linux.
I came upon a very weird problem after installing my Arch - my power button is not working (ofc in the OS, laptop boots up normally). It's not being detected, I tried looking for any events by running acpi_listen with acpid, journalctl -f, xev etc - nothing!
It looks like it's not detected or anything.
My laptop is Dell XPS 13 (2015) 9343 model. I followed the installation guide, being guided by my friend who's been working with Arch Linux for a year now and I believe I did everything I should have, yet the power button is somehow 'dead' to my OS.
I tried looking for similar topics both here on Arch forums and generally with the help of uncle Google, but no luck. I really ran out of ideas, as I mentioned I'm new to Arch, my Linux knowledge was limited to distros like Ubuntu or Mint, so I can't think of a place where I should start looking for the problem. I thought of bootloader config, but I don't want to mess it up without having some strong and confirmed ideas what to do with it.
Has anyone came across a situation similar to this one? Any help will be greatly appreciated.
I didn't really know what should I "attach" to this question, so if any of the outputs are needed just let me know.
Thanks

Re: Power Button not working in Arch - no events of power button

Let's start with the basics. Install the evtest package and post the output of sudo evtest.  You can kill it with Ctrl-C when it asks to select an event number.

Re: Power Button not working in Arch - no events of power button

This is the output of evtest. I see some "Power Button" on event2, that's a good sign I guess.

sudo evtest

Re: Power Button not working in Arch - no events of power button

It is smile  There is also one on event 4.
Try this.  sudo od -x /dev/input/event2  And push the button.  If nothing happens, push it a a dozen more times.  Do you see any hex output when you push the button ?
Do the same thing for event 4.   

Also, if you can find your Xorg log and post it (be sure to use BBCode code tags)

Re: Power Button not working in Arch - no events of power button

Ok, so I tried it both on event 2 and 4.
On event2 I pushed it a couple times, no hex output appeared, but there was a reaction - power menu popped out (I have set in my XFCE power manager to Ask, when I click the power button and so it did).
On event4 some hexoutput appeared and power menu asked me again.
Here's what came out:

 sudo od -x /dev/input/event4
0000000 9676 56cd 0000 0000 94e7 0006 0000 0000

Re: Power Button not working in Arch - no events of power button

I tried to do some diggings on my own, and I found out that there might be a problem for Xfce-power-manger (which I'm using) when there are 2 power buttons detected. This is the output of /proc/bus/input/devices with 2 power button entries:

I: Bus=0019 Vendor=0000 Product=0001 Version=0000
N: Name="Power Button"
P: Phys=PNP0C0C/button/input0
S: Sysfs=/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0C0C:00/input/input3
U: Uniq=
H: Handlers=kbd event2
B: PROP=0
B: EV=3
B: KEY=10000000000000 0

I: Bus=0019 Vendor=0000 Product=0001 Version=0000
N: Name="Power Button"
P: Phys=LNXPWRBN/button/input0
S: Sysfs=/devices/LNXSYSTM:00/LNXPWRBN:00/input/input5
U: Uniq=
H: Handlers=kbd event4
B: PROP=0
B: EV=3
B: KEY=10000000000000 0

So I'm guessing that one of them is probably my PrtScr button which is also a power button... for my Wifi. The question is - how can I help xfce power manager help distinguish between them two? I think this might be causing all the trouble...

Re: Power Button not working in Arch - no events of power button

Bump. I could really use some help.. I'm stuck and my button still doesn't work. I figured that it is recognized, but I have to push it like 50 times and very fast (don't really know which factor is more important here, but eventually after I push it like a crazy person it pops up my xfce power management menu, as I have selected the "Ask" option). Why is this happening? Button event should be recognized immediately, I know it's not a hardware issue, cause the button worked just fine under Windows. Any suggestions...?

Re: Power Button not working in Arch - no events of power button

So, couple of months has passed and I kept working without a properly functioning Power Button, trying to just work around it somehow (with key shortcuts etc). I was hoping some new kernel updates would "fix it for me" but the issue is still here, unfortunately. I believe my knowledge about Arch has grown since, but the problem seems to be tougher than I thought it would be. The interesting thing is I think I'm the only owner of XPS 13 9343 that has encountered this kind of issue with it. I'm currently thinking about reinstalling my system completely, but before I do that I wanted to get some more info from more experienced Arch users, so if any of you has got any idea what else I could do/check/fix then please, help a fella out...

Re: Power Button not working in Arch - no events of power button

Try changing your Power Manager setting to "Shutdown", clear your saved sessions, logout (don't save the session), login, then try the button. I should add, hold the button for for fifteen seconds or so- sometimes the response can be slow.

Re: Power Button not working in Arch - no events of power button

I have Thinkpad t460p and I thought that I have the same problem.

But after this

I figured that was the problem, I didn't hold the button long enough. Though the hold time for my power button is around 3 seconds or less.

I'm using Thinkpad x1 gen7 and I found holding the power button for several seconds(1 second for me) could work(suspend in my case). wink
