System runs 20-30% (CPU) on idle on a brand new HP Omen

[jijiduck]

Hey ! My system runs at 20-30% on idle so I went to check on Process Explorer what exactly is causing it and found out it is ACPI.sys. Tried many solutions that I found on Google and none of it worked for me. The only way to calm that is to put the pc in standby mode and come back to stop the overconsumption of the CPU. Please help!

Change the Power Options so it's high performance. See if that resolves the issue

Could always upgrade to latest April 2018 edition of Windows

In fact its a problem that I have since my purchase a month ago. and pilot and spring windows 10 are up to date. Its a problem related to HP in view of the HP topics. I join you the catch of the problem:

Try enabling the new Ultimate Performance mode. There maybe a way Windows is saving power via advanced power management only found a new CPUs. Ultimate mode disables this which prevents high latency. In theory, might solve it.

I had to add it manually via command prompt. Just FYI

My approach to a pre-built system is to wipe the factory image and re-install Windows from scratch. I don't trust how the big system builders configure their systems.

I had the same issue as well.
Updating Windows ,BIOS or the drivers did not help.
After multiple trial and error, I have found that Intel rapid storage technology app is causing the hike in CPU usage.
Though ACPI.sys is something seems to be related to Power setting, Uninstalling rapid storage technology helped to resolve the issue.
