Hi

I’ve updated my BIOS to the latest version (sp106115) and since then my exhaust fan is not working anymore. I got another fan as I thought it might be the problem and still no result. Everything else works and HP diagnostic doesn’t show any error eider. Anytime I start my PC I get the error 90B which is right as the fan is not working. Here below the details of my desktop

Seri # ;  [personal info removed]

Model; Pavilion 570-p081nd

Product ID; 1NG42EA

Motherboard ID; 82FE

Bios version; 82FE vF.02

It seems to me that I should get back to the old bios version but don’t have it any more. Any solution?

Thx in advance

Farshad
