Failed to start daemon for power management

Sometimes when I shut down it hangs at the message [failed] failed to start daemon for power management. I've looked to see if this problem has happened before in 20.04 or later. But I didn't find it. I have an extra built-in SSD which is seen as /share. I have 2 SSD 2TB /dev/sda and /dev/sdb.

I have tried sudo apt install systemd:amd64 systemd-timesyncd:amd64 but they are already up to date.

I have no idea what to look for to prevent this. What should I do?

I may have the same problem with 20.10 on an Asus Aspire 5332 laptop. A second or two after the POST, disk activity stops. I found a couple of solutions:

1. The laptop boots OK if I remove the battery and run the laptop using the mains power supply - Which rather defeats the reason for owning a mobile device!
2. After staring at a blank screen for 5 mins, I pressed Ctrl-C which (coincidently?) got the boot going again.

I'm guessing that there's more going on than meets the eye, but it's w-a-y beyond my pay grade :-/

The 'Important' Log said that org.bluez had timed out, but if I look at what happened at 9:43:12 ...
