There a several other forum entries describing the same issue, but without any published solution.
Latencymon and process explorer from sysinternals show, that ACPI.sys is the culprit. It put a 100%CPU load on core CPU 0 (cire i7 with 6 cores). I am on the lates BIOS version
Any solutions for that?

HP DO SOMETHING ABOUT THIS!
It is so infuriating to deal with this issue on a constant basis! It eats the battery, makes the system much slower, and makes the fan constantly loud. This is not what I paid for!
I've seen other manufacturers fix this issue a long time ago. How can HP afford to not even comment on the issue? I've had to deal with this since buying the laptop in July 2019. Never again will I make the same mistake.

The issue is resolved on my laptop for the moment. I got the feeling it was related to screen power off/on.
Installed latest NVIDIA Quadro drivers from NVIDIA webpage version 18.104.22.16892 (7.April 2020)
went to powerplan "balanced" and restored default settings.
Then changed PCI Express /Link State Power Management/ both:OFF
changed "Turn off display after" to NEVER.
that solved it.
I did not have the time to trace it down to the single point the solved it.
In the meantime I tried "Turn off display after " 5 minutes and it still looks fine. Might be related to
* video driver
* powerplan restore default settings
* PCI Express / Link state power management.
