Windows 10: ACPI.SYS thread taking high cpu

I have tried everything except doing stuff with the bios

nothing has worked

:)

 

ACPI.sys have high CPU load on ntoskrnl.exe

Hi,

I noticed that my laptop's fan often kick in when idling or when doing light work, and that's when I found that System is having a relatively high CPU usage (~15%, not much I know, but it's enough to make my laptop's fans running like crazy and it takes
up at least one whole CPU logical processor). Restart often fix the problem, but this high idle load would even return after starting up the laptop.

Upon checking with Process Explorer, I found that ACPI.sys is using a lot of CPU threads. That's as far as I can diagnose, and I don't know how to troubleshoot this problem further. I need your help!

 

Windows 10 System High CPU Usage ACPI.sys

ZigZag ZigZag ZigZag ...

It seem to be exactly the same problem with the same Macbook pro 11,2 model: hight CPU usage ~10-20% with System. The thread is ACPI.sys+0x23270.

The BootCamp drivers build is 6136.

Thanks

 

'System' process high CPU usage "ACPI.sys!GetNameSpaceObjectNolock"

hi

I have a hp ProBook 650 G2 with

Microprocessor: Intel(R) Core(TM) i7-6600U CPU @ 2.60GHz

system board: 80FD KBC Version 22.73

System BIOS: N76 Ver. 01.42

system Memory: 16GB

windows specifications

Edition: Windows 10 Enterprise

Version: 1903

Installed on 03/09/2019

OS build 18362.356



However, the CPU is always running between 18 to 25 % on the System process even when the laptop is idle.

Using windows performance analyser from 18362.1.190318-1202.19h1_release_WindowsSDK.iso

I can see it's the ACPI.sys which is consuming the CPU,

After loading the symbols in WPA after capturing computation

I can see its ACPI.sys!GetNameSpaceObjectNolock with

ntoshrnl.exe! strchr and ACPI.sys!memcpy that is consuming the CPU.

What I can not work out is how to stop or slow this process down.



Can someone please point me in the correct direction,

It’s not helpful to have a lovely laptop and wasting 25 % CPU on this for no reason I can see.

I can provide the WPA files if it would be of use.





Things I have tried to identify the problem, but none of this stopped this high CPU usage.

a Clean Boot

running in save mode

disk optimisation

disk clenup

some I can not even remember.
