Hi,

 

the fan is always running. It seems to be an BIOS problem. By upgrading on Win 11 with the newest BIOS version (Q78 Ver. 01.28.00) the problem came up. I tried to use an older BIOS version (Q78 Ver. 01.16.00), but nothing changed.

 

The fan runs randomly on 100 %, somestimes for several hours, sometimes for 20 minutes.

By the way, temp is low ~ 35° - 40°

 

I would really appreciate, if someone (HP customer service?;)) could help me! THX!

Hi,

i already cleaned the vent before!

And the fan is running very randomly.

In another post i read about the Bios problem with the 850 G5. They solved it with the Bios downgrade.

 

I am not sure what to do. With the old Bios it is a little bit better, because the fan is running max for 20 minutes and not for several hours.
