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.

Hi

I have experienced this kind of issue before with my client. It happened to be that the fan cable was not connecting properly.

Have the Laptop open and ensure that the fan connector is properly connected.

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.

Well, you said you update the BIOS and the fan quit. Then you said you installed the old BIOS and the fan remained not working. So (a) in my own experience, I have not seen BIOS make a fan quit - I have seen BIOS make a fan behave and (b) you have tried 2 different BIOS and the fan remains not working.

1. Yes, it could be a coincidence.
2. Check the BIOS settings to do with power, CPU and fan (if any setting exists).

I have not seen a BIOS update allow the CPU to overheat.

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.
