Dell XPS 9560 Ubuntu 18.04 freezes after login without AC only in Intel mode

I am having trouble with my new 18.04 installation while logging in Intel mode without AC only, when power cable is plugged in everything boots fine in any mode.
I installed drivers (nvidia 390) and configured:



GRUB2 "quiet splash intel_pstate=enable acpi_rev_override=1 nouveau.modeset=0"



Everything works fine, but I need good up-time from my battery, and with working Nvidia adapter this unreal (almost 30 watt in idle power consumption). So I disabled it with nvidia-prime and after reboot got freeze right after I input my password on login screen and hit enter, I see a blank color page and a frozen cursor. Tried dozens time.



P.S. Wayland doesn't help.



What shall I do, please advise!
