    20% cpu usage by 'System' after sleep - ntoskrnl.exe / ACPI.sys / hal.dll


    Hello,

    I can't recall when this started happening but even after a clean installation of Windows 10, when my laptop goes out of sleep the 'System' process uses 20% of my cpu. Process explorer shows that 'ACPI.sys' is to blame. I already tried all the basic fixes that I found for a similar problem, most were saying its a faulty driver so I ran a xperf trace for WPA but couldnt find anything exept for some loop calls to 'HalpPCIConfig' :

    link to the '.etl' trace: https://ufile.io/ljra3

    The only thing I have found is a weird behaviour when I disable the 'USB 3.0 eXtensible Host Controller' in device manager the pc wont go out of sleep and when I uninstall them and try to go out of sleep it staight crashes and reinstalls them.

    I'm truly lost now and would appreciate any help.

    My laptop is a 'msi GS60 6QE ghost pro 4k'

    Sorry if didn't respect some posting rules.

    Thanks for helping,

    Wylley

    :)

    ntoskrnl.exe / ACPI.sys. CPU usage Windows 10

    I tried clean boot - Nothing has changed.

    - Power on - CPU ¬15% system ( CPU-0 copy) / ntoskrnl / ACPI

    - Restart - no issue

    - Sleep - no issue

    - Hibernate - no issue

    DISM

    "The restore operation completed successfully.

    The operation completed successfully."

    SFC

    "Windows Resource Protection did not find any integrity violations."

    I think problem is with BIOS or with Windows

    AppleMobileDeviceService.exe consistently takes 50% of CPU usage.

    Original title: An App. called AppleMobileDeviceService.exe consistently takes 50% of CPU usage. I am not using iTunes. Apple says iI should ask Microsoft. I use AX oper. sys.

    An App. called AppleMobileDeviceService.exe consistently takes 50% of CPU usage. I am not logged on to iTunes, nor is my iPod connected to my PC when this .exe runs with 50% usage. Apple suggested I contact Microsoft. I use AX oper. sys. Apple suggested
