I have the 15-dc0015np Omen by Hp and using the Ubuntu 18.04, this issue appears when the battery is full and the charge is pluged. With the kernel 4.18 this bugs dissapear, but another one appears like this "Namespace lookup failure, AE_NOT_FOUND". I have tested all grub options and doing acpi=off works, but obviously I lose all acpi function, like reboot or shutdown. Regards
