ZBook 15 G5 system/ACPI.sys high CPU usage

ZBook 15 G5
Microsoft Windows 10 (64-bit)



My laptop is suffering from the same critical problem described very well in, where the system-process uses up 100 % of CPU 2 and 50 % of CPU 0 time (while the computer is idle).


The process always starts a few minutes after booting the system, and nothing has helped. I have updated the BIOS to Q70 Ver. 01.08.01. Others have found that this issue seems to be in the firmware and only HP can fix it. I am creating a new thread to let HP know there are more of us affected, because it is not possible to reply to the one I linked.


Please HP, can you let us know if you are looking into this issue and when can we expect a solution? Frankly I think it is unacceptable that high-end laptops would have to suffer from such critical firmware issues for long periods of time. Thank you.
