EliteBook 840 G5 fan operation

Seems better to me yes.  Pretty good now - fan stays off under low load and pretty quiet still under most loads.

Thanks!

I am looking to buy the HP 840 G5 or a Fujitsu U938 laptop. What would you recommend me?

I have the same situation, but currently can not install a firmware update - company managed...

I tried a few things in powersettings via Windows, and it seemed to be a working workaround. Maybe it helps somebody else:

- System settings - Energy settings, Advanced

- Intel Graphics Power Plan => "Maximum Battery Life" on AC

- CPU, Minimum => 5% on AC, Cooling => Passive on AC, Maximum Performance 99% on both

- Dynamic GPU => Optimize energy savings on AC (like on battery)

- AMD GPU, Powerplay => Optimum Battery on AC

Solved it for me. Reduces performance for GPU mainly, but really doesn't matter for my Office use case. I think it is linked to dedicated GPU switching which is done on AC with the default settings. I also noticed that the problem don't occur with every use case, but especially with some apps which triggers Windows to use the GPU.

When I activate the Airplane Mode, the problem is gone...

i had the same issue where the fan will be on most of the time and it was annoying. Atleast for me the problem resolved once i installed radeon graphic driver from HP support site. This drive doesn't often comes factory installed and looks like without this its taxing the CPU. I had to optimize my GPU and brighntess/performance settings after installation.
