laptop powers off when headphones are pluged

[Siarhei Hladyshau]

Every time I plug headphones to my laptop (while using battery) it immediately powers off. I can only recognize the window saying: "unknown audio device", and suggesting choice: "headphones", "headset" and "microphone". However it works fine, when laptop is plugged with AC adapter. But when I close laptop with both AC adapter and headphones plugged in, instead of going to sleepmode it powers off.

I have googled the solution to disable Intel Audio power saving mode by editing /usr/lib/pm-utils/power.d/intel-audio-powersave.

#INTEL_AUDIO_POWERSAVE=${INTEL_AUDIO_POWERSAVE:-true}
INTEL_AUDIO_POWERSAVE=false

But it didn't help. Laptop still powers off.
I have checked syslog for exact time when I plugged headphones, but didn't found any recordings.

I am using Ubuntu 16.04.
My laptop: Dell Inspiron 5559
My headphones: Sound Intone E6

update: It helped to disable TLP to get rid of this bug. So, now when I plug the headphones the laptop does not shut down. However, when I close my laptop instead of going to sleep mode it shuts down. So disabling TLP did not help to get rid of this bug completely.
