Bios update failure HP Pavilion

Hello:

I have an HP Pavilion DV6, running Win7. I updated the bios. I now get a message on startup that says my fan isn't working properly. The machine overheats and shuts down.

I tried the HP bios restore. That didn't work. The resulting bios was the new one, not the original. I then installed the old bios from an HP download. My fan is still malfunctioning.

I encountered the following advice:

Do you concur? Is there and easier fix?

Thanks.

It is not likely a BIOS problem, and if the fan is connected properly (per the above post), then the fan is likely defective or the circuitry running it has a hardware problem.

Thank you, but what do I do with the fact that the fan was working before and until the bios was updated?

The very next boot after the bios update produced HP fan error 90B. If unrelated to the bios update, the coincidence of the timing of the fan failure is uncanny.

I see your point...

I updated the bios because the fan appeared to run continuously. It worked, but not optimally.

I thought the problem was not the fan, but that I was continuously backing up offsite, in addition to running simultaneous multimedia apps. But, it may have been the fan all along.
