I have the same problem but updating the BIOS didnt work. Please help me, as my fan runs automatically always and 90B error is displayed always at startup, from the very first day I bought HP Probook 4430s. Even the vents are clean and I regularly clean them. Still it shows the same error. I have also replaced the fan but still it shows the same error.

Please suggest me what can be the reason and what can be a possible solution.
