Cooling fan isn't working.

[MistyAgile45]

I recently got my laptop back from having a screen replacement and after about a week or two I noticed that the laptop is silent when it's on. Usually there's the sound of the fans working but there's no sound. Today I restarted the laptop and it comes up with a message saying the system has detected the cooling fan isn't working.

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

To fix this error, use the following steps:

1. Press Enter to clear the message and allow the system to boot to the Windows Desktop.

2. Shut down the computer, and then inspect and clean the exterior vents to remove dust buildup by blowing air through the vent openings. Dust can accumulate inside the vent openings and around internal cooling components, preventing the removal of heat.

   For more information on reducing heat inside your computer, see Reducing Heat Inside the PC.

3. After you remove the dust, turn on the computer. If the error message persists, continue with these steps.

4. Perform a hard reset. Performing a hard reset can reset recorded thermal values in memory and enable you to use the computer again, even if only for a short time to access and save any important files before service.

   For more information on performing a hard reset, see Use Hard Reset to Resolve Hardware and Software Issues.

5. In some cases, updating the BIOS might help prevent this error from occurring.

   For more information on how to update the BIOS, see Updating the BIOS.

6. Have the computer serviced to clean internal components and replace the system fan if necessary. Make sure to address the following items when servicing:

   • Thoroughly remove dust from all internal cooling components.

   • Make sure wires from the system and CPU fans are connected securely to the motherboard.

   • Confirm the system fan blades spin correctly, and the fan is not producing loud noises. If not working correctly, replace the system fan.

   • Remove old thermal compound from integrated circuits and heat sinks and replace with new thermal compound.

Hope this helps! Keep me posted for further assistance.
