Troubleshooting Steps:

1. Check the laptop fan in the System Settings and make sure it’s turned on.
2. Make sure the fan is physically connected to the laptop board and check for any obstructions.
3. Run a stress test to check the hardware for any errors.
4. If the fan is still not working, clean the fan with compressed air.
5. If the fan is still not working after cleaning, it may need to be replaced.
