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.
  • Worn-out Fan Bearings: Continuous use can wear out the fan bearings, leading to increased friction and reduced fan efficiency.
  • Fan Malfunction: In some cases, the fan motor itself might fail due to electrical issues or physical damage.
  • BIOS Issues: Outdated or corrupted BIOS settings can sometimes interfere with fan control, triggering the error.
  • Overheating: If your laptop is consistently overheating due to demanding tasks or insufficient cooling, the fan may be overworked and eventually fail.

How to Fix the HP System Fan 90B Error

Before attempting any fixes, back up your important data as a precaution:

  1. 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.
  2. 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.
  3. 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.
  4. Adjust Power Settings:

    • Lowering your laptop’s performance settings can reduce heat generation and alleviate stress on the fan.
    • Go to Power Options in Control Panel and select a more balanced power plan.
  5. Use a Laptop Cooling Pad:

    • A laptop fan stand provides additional cooling to your laptop, reducing the load on the internal fan.

When to Seek Professional Help

If the troubleshooting steps above don’t resolve the error, it’s best to seek professional assistance. Internal hardware issues, such as a faulty fan or damaged components, require expert diagnosis and repair.

  • Contact HP Support: HP offers technical support services, including diagnostics and repair options for their laptops.
  • Consult a Qualified Technician: A certified computer technician can diagnose the issue and provide appropriate solutions.

Preventative Measures to Avoid Fan Errors

  • Regular Cleaning: Clean your laptop’s fan and vents every few months to prevent dust buildup.
  • Avoid Blocking Vents: Ensure proper ventilation by not placing your laptop on soft surfaces like beds or blankets.
  • Monitor Laptop Temperature: Use monitoring software to keep an eye on your laptop’s temperature and identify potential overheating issues early on.
  • Update Drivers and Software: Regularly updating drivers and software ensures optimal system performance and can prevent compatibility issues that may affect fan operation.

By understanding the causes and solutions related to the “HP System Fan 90B” error, you can take proactive measures to keep your laptop cool and prevent potential hardware damage. Remember, addressing the issue promptly is crucial to maintaining the health and longevity of your HP laptop.
