Bios downgrade

[Mugii_2442]

Hello i need help with downgrading the bios on my HP 17-cb0070nr (8603 board)  from Ami f.48 to Ami f.47, because it is causing issues like its running way hotter than usual and the fans are at high constantly even if im not running any programs. This only started happening right after i updated it, and ive also already cleaned it and checked the fans and everything is working good.

Do you have valid HP warranty ?

You need to provide the serial number of your notebook here:

To find serial number follow:

Hello @Mugii_2442 

If there is an update of the BIOS version from HP in the near future, this might help.

Unfortunately, I can't wave a magic wand. My options are exhausted... 

Kind regards

In the meantime read OMEN at wikipedia, then you can understand the meaning of the product name a little better...
