Hp Omen laptop stuttering

[ignas2006]

Hello, I am experiencing intermittent system-wide freezes on my HP OMEN Transcend 14 (Intel Core Ultra 185H).

The issue appears as short freezes lasting about 0.3–0.7 seconds, where both video and audio freeze briefly and then recover. This happens randomly under all conditions: gaming, browsing, light applications (e.g. Excel), and even when the system is mostly idle. The problem is not related to system load.

I have already updated the BIOS and all drivers, adjusted power settings, and disabled Intel Dynamic Bandwidth Management and Intel Innovation Platform Framework services. The issue still persists.

Because the freezes occur even under minimal load, this appears to be a firmware / ACPI / power management related issue rather than a software problem.

Disconnect all USB device and test. If issue remains then download and Run LatencyMon (from Resplendence) for 15-30 minutes during idle/mixed use to pinpoint high DPC latency culprits like "dxgkrnl.sys" (graphics) or "intelppm.sys" (power).

I am experiencing the exact same symptoms with the same product.

Have updated all HP and Nvidia drivers, and BIOS.
Checked power plan.

Repeated freezes every 4 minutes or so.
This only started occuring recently, so I would assume it is due to a bug in a firmware update.

I have ran LatencyMon and it is showing ACPI.sys acting abnormally:ACPI.sys is faulty

Do these:

1) In device manager, I find "HP Application Enabling Services" driver, then go to its Properties, Driver, Roll Back Driver

2) In the Settings, Apps, Installed apps, find "HP One Agent", Uninstall

[jl921]

1) Rolled back HP Application Enabling Services.
2) Have already uninstalled HP One Agent.

Still having the same issue of system lockup every 5 minutes or so.
LatencyMon showing similar results as previously mentioned.

Will try to run the HP tests now.

EDIT:
All HP Support Assistant tests and diagnostics show no failures.

Look for its service in services windows and disable it and restart

Did it help I am also facing the same issue

[Venom21 · Accepted solution]

Do this:

- Press Win + R, type services.msc, Enter.

- Find HP One Agent Service, right-click > Properties.

- Set Startup type to Disabled; click Stop if running > apply and OK.

- Close window, restart laptop.

- Test it.
