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


    I have a asus n 550jk

    processor: IntelR CoreTM i7-4700HQ CPU @ 2.40GHz

    system board: 80FD KBC Version 22.73

    system Memory: 16GB
    windows specifications

    Edition: Windows 10 Enterprise





    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 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,







    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.

    i updated all windows and drivers.
    i use Silicon Power Ace A55 SATA3.0 Internal SSD - 240 GB
    and     ST1000LM024 HN-M101MBB normal 1TB hard .

    1TB is included in caddy instead of dvdRom.please help me to sove it

    :)

    '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

    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.

    system process high cpu usage

    Hello,

    To fix high CPU usage issue, please refer these steps:

    Try to identify the process creating this issue.

    Download Process Explorer from Microsoft:

    Process Explorer - Windows Sysinternals

    Run the tool then select the system process, right-click and select Properties.

    Switch to the Threads tab. This will show which file is using the excessive CPU usage, from which you can then attempt to diagnose it.

    Also refer: [FIX] Windows 10 High CPU Usage Problem

    Let us know if this helps!

    Note: Included link in this reply refers to blog post by a trusted Microsoft MVP.
