HP 15s (AMD Ryzen) laptops freezing and shutting down after Windows 11 24H2 update

[RSC6890]

Hello HP Community,

We’re encountering a serious stability problem affecting multiple HP 15s laptops in our organization after upgrading to Windows 11 version 24H2.

Since updating to Windows 11 24H2, our HP 15s laptops with AMD Ryzen processors have started to:

• Freeze or hang unexpectedly

• Suddenly shut down without warning

• Occasionally become unresponsive for several seconds and then restart

These issues did not occur on Windows 11 23H2, and rolling back to that version immediately restores stability.

Environment Details

• Model: HP 15s series (AMD Ryzen 5 with Radeon Graphics)

• Quantity affected: 20 laptops (majority of deployed units)

• BIOS: Updated to latest version via HP Support Assistant

• Drivers: Latest AMD Chipset and GPU drivers installed (from HP and AMD official websites)

• Operating System: Windows 11 Pro 24H2 (Build 26100.xxxx)

Troubleshooting Steps Tried

1. Updated BIOS, chipset, and display drivers on all affected systems.

2. Verified thermal and hardware health through HP UEFI Hardware Diagnostics — all passed.

3. Tested with different Windows power plans and clean boot configurations.

4. Performed driver reinstallations and system integrity checks.

5. Rolled back one laptop to Windows 11 23H2 → no freezes or shutdowns after rollback.

Request for Assistance

We would appreciate HP’s guidance on the following:

• Is this a known issue with HP 15s Ryzen models running Windows 11 24H2?

• Are there any new BIOS or driver updates planned to address this behavior?

• What workarounds are currently recommended (for example, disabling Modern Standby, adjusting power settings, etc.)?

Hi @RSC6890,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand your HP 15s laptops with AMD Ryzen processors are freezing and shutting down unexpectedly after updating to Windows 11 version 24H2. Let’s go through a few steps and checks that can help stabilize the systems while HP investigates further.

1. Confirm the Latest BIOS and Firmware

Visit the HP Support website and enter your exact HP 15s model number.

Check if a newer BIOS has been released after your last update — HP occasionally publishes silent updates in response to Windows build changes.

If an update is available, install it using HP Support Assistant or manually via USB.

2. Update AMD Chipset and Graphics Drivers (Manual Clean Install)

Download the latest AMD Chipset Drivers and Radeon Graphics Drivers directly from AMD’s official site (not Windows Update).

Use Display Driver Uninstaller (DDU) in Safe Mode to remove existing drivers before installing the new ones.

Reboot after each installation.

3. Disable Modern Standby (S0 Low Power Idle)

Some Ryzen-based HP 15s units show instability under Modern Standby in Windows 11 24H2.

Open Command Prompt (Admin) and run:

powercfg /a

If S0 Low Power Idle is listed, disable it via BIOS if possible, or switch the system to Legacy Sleep (S3) mode when the option is available under Advanced → Power Management.

4. Adjust Power Settings

Go to Control Panel → Power Options → Change plan settings → Change advanced power settings.

Under Processor power management, set:

Minimum processor state: 5 %

Maximum processor state: 99 % (temporarily limits boost spikes that may trigger instability).

Also disable Fast Startup under Control Panel → Power Options → Choose what the power buttons do.

5. Check HP CoolSense or System Event Utility

Ensure HP System Event Utility and HP CoolSense are up to date — older versions may conflict with 24H2 power transitions.

If crashes occur when the system is idle or closing the lid, try uninstalling HP CoolSense temporarily for testing.

6. Run System Health Validation

Boot into HP UEFI Hardware Diagnostics → System Extensive Test again to reconfirm thermal and voltage stability.

Record any “Thermal Trip” or “Unexpected Shutdown” entries in Event Viewer → System Logs for correlation.

I hope this helps.
