Why is My HP Laptop Fan Not Working?
Several factors can contribute to the “HP System Fan 90B” error:
- Dust Accumulation: Over time, dust and debris can accumulate in the fan blades and vents, obstructing airflow and hindering fan rotation.

How to Fix the HP System Fan 90B Error
Before attempting any fixes, back up your important data as a precaution:
-
Clean the Fan and Vents:
- Power off your laptop and unplug it.
- Use compressed air to blow out dust from the fan vents, typically located on the sides or bottom of your laptop.
- Be careful not to spray directly into the fan at close range, as this can damage the blades.
-
Update or Reinstall BIOS:
- Visit the HP support website and download the latest BIOS version for your specific laptop model.
- Follow the instructions provided by HP to install the BIOS update.
-
Check for Physical Obstructions:
- Carefully inspect the fan area for any physical obstructions, such as a piece of paper or a foreign object lodged inside.
