Notebook freezes when starting

[delei]

My HP Spectre x360 Laptop 16-aa0780nz (Product Number: 9Q194EA) regularly freezes right after the first startup.
The device becomes unresponsive and needs about 20 minutes to cool down before it starts working normally again.

This behavior occurs only on the very first startup – once the laptop has been running for a while, it operates normally and remains stable.
What is unusual is that the device heats up significantly within just a few minutes, even though no programs or background processes are running at that point. Sometimes the fan spins at maximum speed immediately after startup, while at other times it does not spin at all.

Since when:
The problem started after upgrading to Windows 11 Pro. All updates (BIOS, firmware, drivers, Windows) are installed and up to date.

Troubleshooting already performed:

• Ran HP Diagnostics Tool → all tests passed, no issues found

• Checked ventilation slots → clean and unobstructed

• Tested with external cooling pad → slight improvement, but not practical for regular use

My questions for HP Support:

1. Is this a known issue with this model?

2. Could the root cause be related to the cooling system, power supply, or a firmware/driver problem?

3. What further steps do you recommend to restore reliable operation of the laptop?

Thank you in advance for your support.

Best regards

@delei, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

It seems like you're dealing with a thermal or power management issue that only occurs at startup, likely related to how the system is initializing on Windows 11. Let's go over some troubleshooting steps:

BIOS and Power Settings:

Reset BIOS: Go into BIOS (press F10 at startup) and reset to default settings.

Check Power Settings: Make sure your power plan is set to Balanced or HP Recommended.

Check Drivers:

Update/rollback drivers: Make sure your graphics and chipset drivers are updated for Windows 11.

Thermal Drivers: Check if your Intel Dynamic Platform and Thermal Framework driver is up-to-date.

Windows 11 Compatibility:

Check for Errors: Open Event Viewer (search it in Start) to find any warnings or errors after startup.

Clean Boot: Try starting Windows without third-party apps running (search for msconfig > disable non-Microsoft services).

System Restore:

If the issue started after upgrading to Windows 11, you can try a System Restore to a point before the upgrade.
