Decoding the HP Fan Error 90B
This error code signifies that the fan responsible for cooling your HP laptop’s internal components is not functioning correctly. This can be due to various factors, ranging from simple dust accumulation to more complex hardware failures.
Common Causes of HP Laptop Fan Error 90B
- Dust and Debris: Over time, dust, dirt, and debris can accumulate within the fan blades and its housing, obstructing airflow and hindering its performance.

- Faulty Fan Motor: A malfunctioning fan motor can prevent the fan from spinning at the required speed or from spinning at all.
- Loose Connections: Loose or disconnected cables between the fan and the motherboard can disrupt power supply and communication, triggering the error.
- BIOS Issues: Outdated or corrupted BIOS settings can sometimes interfere with fan control mechanisms, resulting in error codes.
Troubleshooting the HP Fan Error 90B: Step-by-Step Solutions
- Restart Your Laptop: Begin with the simplest solution. Sometimes, a temporary software glitch can be resolved with a reboot.
- Clean the Fan Vents: Power down your laptop, unplug it, and use compressed air to carefully blow out dust from the fan vents.
- Update Your BIOS: Check the HP support website for the latest BIOS version for your specific laptop model and follow the instructions to update it.
- Check for Physical Obstructions: If comfortable doing so, you can carefully open your laptop’s back panel to inspect for any physical obstructions around the fan.
- Run Hardware Diagnostics: Most HP laptops come with built-in diagnostic tools accessible through the startup menu (usually by pressing F2 or Esc during boot). Run the fan test to identify any hardware issues.
