Public bug reported:
This might be a duplicate of #1756455
HP Spectre x360 13", model 13-ae004na, secure boot on, latest BIOS
F.15A, Ubuntu is the only system on disk.
When using kernel 4.15.0-13 the system does not power off but instead
reboots. Both halt -p from the command line and menu action leads to
reboot instead of turning hardware off. 4.15.0-12 has the same problem
(see #1756455). Booting with kernel 4.15.0-10 resolves the issue, system
turns off power and stays powered off.
* secure boot enabled or disabled makes no difference
* kernel 4.15.0-10 correctly powers off system (halt -p) every time,
power source makes no difference
* kernel 4.15.0-13 correctly powers off system only when running on AC
* kernel 4.15.0-13 does NOT power off system (reboots instead) when AC
power is NOT connected (running on battery) every time
