System Fan (90B) Error / HP Pavilion dv7-4060us

Hi. I have a Pavilion dv7-4060us notebook, Windows 7 Home Premium, 64-bit. I had an overheating problem not too long ago that caused my notebook to shut down on it's own. I bought a cooling pad to help with the overheating, which helped. But now, everytime I start up, it gives me a black screen reading "Operating System has found that a cooling fan has stopped working" or something similar. The error code was "System Fan (90B)." How do I get rid of this error message? Post back here or reach my email at bamab0y25@yahoo.com. Thanks.

This PreBoot Diagnostics that is indicating there is an issue with system fan. It would be a case of System Fan not running or running at slower speed than it should...

I would suggest, try doing power drain, by disconecting AC adapter, removing battery and pressing the power button for few secs... if that always you to boot to the OS, that Update the BIOS if not than I would suggest contacting HP Tech Support for getting your unit serviced...

Hey Juan,

A 90b error is related to the system fan. Make sure to clean out all the CPU vents. I would recommend using compressed air to make sure their is no debris or dust clogging the vents. If the vents are clean I would recommend contacting HP technical support since you are still in warranty.

Good afternoon. The same problema. Kuler clean and not working at startup. Decision to push the screwdriver blade and it will work. New laptop and cooler defective.

Sorry to hear about that. Are you still in warranty? If so contact HP phone support in your region and they would take care of that for you.

Thanks,
Sean
