How to reverse a bios update

[CHSSC]

Hi, I did an HP bios update from HP update site.

Since then I get an error/message every time I boot my computer saying that my fan is not working.

I used the HP testing software to test the fan hardware and it is working just fine.

My laptop is also running slow since he Bios update and some windows update.

I want to reverse all the updates, especially the Bios. how can I reverse the update of the bios to the original version?
