  3. Press and hold the power button for 30 seconds.
  4. Reconnect the power cord and battery (if applicable).
  5. Turn on your computer.

Why HP CPU Fans Fail

Several factors can contribute to HP CPU fan failures:

  • Dust Accumulation: Dust buildup restricts airflow and overloads the fan.
  • Wear and Tear: Over time, the fan’s motor and bearings can wear out.
  • Manufacturing Defects: Some fans may have inherent flaws.
  • Overheating: Consistent high temperatures stress the fan.
  • Physical Damage: Accidental drops or impacts can damage the fan.

Regular maintenance, such as cleaning the vents and ensuring proper ventilation, can help prolong the life of your HP CPU fan and prevent errors.

Important Note:

Always refer to your specific HP model’s user manual or the HP website for detailed instructions and troubleshooting guides.

Key Takeaways

  • Cooling fan errors indicate potential overheating risks.
  • A systematic approach is needed to diagnose fan problems.
  • Remedial actions range from system reboots to fan replacement.

Diagnosing the Issue

When a laptop’s cooling fan stops working, it may display specific error messages and behave erratically. Prompt action is key to prevent damage. This error may show up in many forms like “System FAN ERROR 90B” or “HP Laptop Fan Error 90b”, etc.

Identifying Error Messages

Many laptops, including those from HP, have built-in diagnostics that alert users when there’s an issue with the system’s cooling fan. The error messages that commonly appear on screen might include “System Fan (90B)” or similar notifications. These messages signal that the fan isn’t operating as it should. If you see such a message, it’s a clear sign that your laptop needs attention. It’s crucial to note the exact text as it might guide further troubleshooting steps.

Common Error Messages Alerting Fan Problems:

  • System Fan (90B)
  • Cooling Fan Not Operating Correctly
  • Error: Fan Malfunction

Observing Unpredictable Behavior

Unpredictable behavior can be a telltale sign of cooling fan issues. When a fan fails, laptops may overheat and experience random shutdowns. This is because the system tries to protect itself from heat damage. Other signs include an unusually hot underside or an absence of the fan’s normal spinning sound during operation. It’s possible to confuse these symptoms with other problems. To confirm it’s a fan issue, look for correlating error messages or check the BIOS settings for fan operation statuses.

Corrective Actions

When a computer’s cooling fan fails, it can lead to system damage and data loss. Taking prompt and proper action is essential to prevent such outcomes.

Routine Maintenance Procedures

Keep it Clean: Dust and debris can clog vents and fans. Regular cleaning helps maintain airflow and prevent overheating. Turn off and unplug the computer, then use compressed air to gently clean out the vents.

Check and Replace Battery: If the laptop battery is easy to remove, check it for any signs of damage. A faulty battery can cause overheating which affects the fan’s operation. Replace the battery if necessary.

Technical Resolutions

Update BIOS: Sometimes systems with outdated software will misread fan operations. Updating your computer’s BIOS can fix these errors. Visit the computer manufacturer’s support site for the correct update.

Thermal Paste Application: The CPU needs fresh thermal paste if the old layer has degraded. Remove the old paste carefully and apply a new layer to help with heat dissipation.

Fan Replacement: If cleaning doesn’t fix the fan issue, replace it. Make sure you get the correct part for your computer model. It is often best to have a professional handle this task to avoid damage.

Professional Support: For those not comfortable with technical tasks, seek professional help. A certified technician can accurately diagnose and solve fan-related issues.

Frequently Asked Questions

When a cooling fan error occurs on an HP laptop, it’s key to address it promptly to prevent damage to the system. Below are common questions and steps to help fix the issue.
