Hi,

I think I may have the same problem.

When I shutdown or restart my laptop the process proceeds as normal to
the point where the last message printed on the screen is "Reached
target power-off" and then nothing happens. I then need to push and
hold power button until power switches off.

I setup Systemd persistent logs to allow me to view log messages up
until power off, but again nothing jumps out as being a problem.

I have a Lenovo ThinkPad Laptop; 

DMI: LENOVO 20JAA00FAU/20JAA00FAU, BIOS R0MET48W (1.25) 04/22/2019.


I found this Systemd Debugging tip;

poweroff -f

If this command doesn't work, then Systemd is unlikely to be the
problem and it may be kernel related.

When I tried this command the GUI screen froze and there was a loud
annoying continuous beep.

Pressing and holding the power button turned off the laptop.
