ACPI Error & Reboot

Example: Pavilion Gaming 15-cx0056wm
Microsoft Windows 10 (64-bit)

Machine: HP Pavilion Gaming 15-cx0056wm.

OS: Windows 10 Home.


Please help, I need an idiot's guide to fixing this, if I can.


I recently bought a laptop of the model described above. I'd had the thing out of the box less than an hour when I got the Windows 10 equivalent of a BSOD, which told me SYSTEM_THREAD_EXCEPTION_NOT_HANDLED and ACPI.sys


My machine rebooted and did a Windows update, and I thought maybe that solved the problem (naive, I know), but it did it again today.


I looked around and apparently updating the driver might help, but it also seems like ACPI.sys is kind of central to power management and I really don't want to brick my PC.


Somebody PLEASE help!!

ACPI Error & Reboot




Since this is a new Notebook, I suggest you download and run the HP Support Assistant from this Link:


HPSA will automatically search for all the latest drivers for your Notebook


  1. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.

    Click Updates in the My notebook pane

  2. Click Check for updates and messages to scan for new updates.

     Updates list in HP Support Center

  3. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.

  4. Click the update name for a description, version number, and file size.

  5. Select the box next to any updates you want to install, and then click Download and install.

Also ensure Windows is up to date.


Select the Start  button, and then go to Settings  > Update & security  > Windows Update , and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available


if the issue persists please run the SFC Scan. You can refer to this Link:


Keep me posted how it goes


Thank you and have a wonderful day 😊
