Fan has stopped working error 90b

Hp Envy 13-aho
Microsoft Windows 10 (64-bit)

My laptop fan has stopped working and error 90b is showing on start up. Im fairly sure this occured after I did some overdue updates which included an update doing something with the bios. Whenever the fan would normally come on there is a rapid intermittent clicking sound.  I have tried cleaning vents, updating firware and bios and rollback bios, hard reset etc. Does anyone have any suggestions - the computer hasnt been used all that much so resetting it completely is an option if required. My computer sufferred impact damage which slightly bent the lid and body about a week after I got it - But it has still ran perfectly for 10 months until now! Any suggestions? I could really do with getting it working again! Would reformatting work if this is a software issue? Thanks

Welcome to HP support community.

  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.
