Thank you for posting on HP Support Community.

I see that you're experiencing a 90b error and fan is not working,
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Did this happen after a recent window or software update?
• When was the last time it worked fine?
• Have you made any hardware/software changes?
• Does system boots to the windows desktop?

This message indicates that the system fan is not spinning at the expected speed. This message occurs to help prevent costly damage to the computer.

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.

1. After you remove the dust, turn on the computer. If the error message persists, continue with these steps.
2. 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.

• 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.
