Kernel-Processor-Power Event ID 37

[Deykks]

Hello,

I’m looking for advice or confirmation from HP staff or experienced OMEN users regarding a persistent stability issue.

System

• HP OMEN Desktop (2024 model)

• Windows 11

• Used normally (light gaming, desktop use)

• No overclocking, no hardware modifications

Problem

The system randomly hard-freezes, often while:

• Sitting idle on the desktop

• Running very low-load applications

When this happens:

• Mouse and keyboard become unresponsive

• Screen remains frozen

• No BSOD

• Only recovery is holding the power button

This is not tied to heavy gaming or high temperatures.

What I’ve already done

• Updated BIOS to the latest available version via HP

• Confirmed BIOS update completed successfully

• Verified system temperatures are normal

• Clean Windows environment (no tuning/optimizer software)

• Created a custom High Performance power plan:

  • CPU minimum and maximum state set to 100%

  • PCIe Link State Power Management disabled

  • Wake timers disabled

• Sleep and hibernation disabled

Despite this, the issue persists.

Event Viewer findings

The System log repeatedly records:

• Kernel-Processor-Power (Event ID 37)

These warnings occur in clusters and continue even after:

• BIOS update

• Forcing Windows to maximum performance states

This strongly suggests firmware-level power management intervention rather than a Windows or software issue.

What I’m hoping to clarify

• Is this a known issue with certain 2024 OMEN desktop models?

• Are there any hidden BIOS settings, firmware patches, or HP ad-vis-ories ( relating to CPU idle power states / C-state behaviour?

• Has HP identified motherboard or PSU power-delivery instability causing Event ID 37 and hard freezes at idle?

The system is unfortunately just out of warranty, but given the nature of the fault and the diagnostics already performed, I’m trying to determine whether this is:

• A known design/firmware issue, or

• A hardware defect (e.g. motherboard or PSU)

Any insight from HP staff or users with similar OMEN systems would be greatly appreciated.

Thank you.

Hi @Deykks 

Welcome to the HP Support Community! We're here to help you get back up and running.

I understand how unsettling it feels to experience hard freezes on a high‑performance OMEN desktop, especially after you’ve already taken careful steps like updating the BIOS, verifying temperatures, and creating a custom power plan. 

You’ve done excellent groundwork, and I appreciate the thoroughness of your diagnostics. Let’s focus on additional measures that can help stabilize the system and reduce those Kernel‑Processor‑Power Event ID 37 warnings.

 

Check Windows Power Options beyond High Performance

• Open Control Panel → Power Options → Change plan settings → Advanced.
• Under “Processor power management,” set the minimum processor state to 5% instead of 100%.
  This allows the CPU to idle gracefully rather than being forced to maximum state, which can sometimes trigger firmware‑level interventions.

Disable C‑States in BIOS (if available)

• Restart the PC and enter BIOS (usually F10 or Del at startup).
• Look for CPU power management or C‑State control.
• If present, disable C‑States temporarily and test stability.
  This prevents the processor from entering deep idle states that may cause freezes.

Update Chipset and Intel ME drivers

• Visit HP’s driver page for your OMEN GT15‑2000i and install the latest Intel chipset and Management Engine Interface drivers.

Check PSU and motherboard firmware

• Some OMEN desktops include firmware updates for the system board or embedded controller.
• Run HP PC Hardware Diagnostics (UEFI) to confirm stable power delivery.

Test with Balanced power plan

• Switch to the Balanced plan and allow Windows to manage CPU idle states dynamically.
• Observe whether freezes occur less frequently compared to forcing maximum performance.

Disable USB selective suspend

• Control Panel → Power Options → Advanced settings → USB settings.
• Set “USB selective suspend” to Disabled.
  This prevents devices from entering low‑power states that can contribute to freezes.

Firmware and BIOS double‑check

• Confirm the BIOS version matches the latest listed on HP’s support site for your exact product number.
• If a newer release appears, update again to ensure all microcode fixes are applied.

By experimenting with processor idle states, ensuring chipset drivers are current, and checking BIOS/firmware settings, you should be able to narrow down whether the freezes are tied to CPU power management or hardware delivery.
