Hi, I recently updated the BIOS of my HP Notebook - 15-af008ax to version F.26. I did not make a note of the original version number. After the update, the cooling fan in motherboard stopped working and upon startup it has started showing the 90b error ('cooling fan not working correctly').
Can I fix the problem by reverting back to the old version of BIOS? If so can someone help me identify the version? From the specs, the motherboard model name is 80CC 99.50.
Solved! Go to Solution.

I reviewed your post and I understand that you are getting system fan error 90B on the computer.
Don’t worry, I assure you I will try my best to get this sorted.
The latest version of BIOS available for your computer is F.28 Rev.A. I recommend you update the BIOS from the below link and check whether the issue is resolved.
