If you're experiencing issues with the Trusted Platform Module (TPM) and the cooling fan on your HP 250 15.6 inch G9 Notebook PC, here's how you can address both problems:
Trusted Platform Module (TPM) Malfunction
-
Restart the Computer:
- A simple restart can sometimes resolve TPM errors by resetting the module.
-
Clear the TPM:
- Warning: This will wipe all TPM-stored keys, affecting access to encrypted data.
- Access "Settings" > "Update & Security" > "Windows Security" > "Device Security".
- Click on "Security processor details" and then select "Clear TPM".
- Follow any prompts and confirm actions in BIOS/UEFI if needed.
-
Update BIOS and TPM Firmware:
- Check the HP support website for any available updates that may resolve TPM issues.
-
Remove and Re-add School Account:
- Go to "Settings" > "Accounts" > "Access work or school".
- Disconnect the school account and then add it back to see if this resolves access issues.
Cooling Fan Issues
-
Clean the Vents:
- Ensure the notebook is powered off and unplugged.
- Use compressed air to remove dust and debris from the vents to improve airflow.
-
Check BIOS/UEFI Settings:
- Restart the laptop and enter BIOS/UEFI settings (usually F10 during startup).
- Verify that the fan settings are correct or reset to defaults.
-
Run HP Support Assistant:
- Use HP Support Assistant to run diagnostics on the cooling system components.
-
Check for Software Issues:
- Ensure no applications are unnecessarily taxing the CPU, which could increase fan activity.
-
Inspect the Fan:
- If you're comfortable, open the laptop to inspect the fan for any visible obstructions or damage. If not, seek professional help.
- Enable Fan in Bios: Enabling "Fan always on while on ac adaptor" will sometimes resolve fan related issue
Hope this helps resolve your issue.
