Hi there,

i'm missing a Config for the HP EliteBook 755 G5 (AMD Ryzen 5 Pro 2500U).
Is there any way to add this?

Many Thanks!

Hello, I'm using this config on my Elitebook 850 G5. May it can work on your machine. I couldn't see into the configs folder of the repository, probably, I had found from an issue. But I don't remember which issue.

Looking for a similar one, HP ProBook 645 G4 (AMD Ryzen 7 Pro 2700U).
Every xml I've tried shows a fan speed of less than 0 or more than 100 %.

Thanks SevcanAlkan, but your file didn't work for me at least.

There's a HP Ryzen config included, HP ENVY x360 Convertible 13-ag0xxx.xml, but it doesn't work for me. I don't think the CPU brand is the crucial part here anyway, not sure tho.

I missed the part about Secure Boot in requirements, and I bet I'm not the only one.

Anyway, I disassembled my laptop and found this chip. I hope it's not the TPM chip..
Didn't find any datasheet for it though.

I've tried a little with existing configurations and it seems that the HP EliteBook 8760w could work ... maybe as a basis?
The Fan runs audible quieter but i'm not sure about the display values.
Temperatures are OK with "normal use", have not yet tested under full load.
Best regards!

How about when it's set to Auto, does it change fan speed as expected? Does it run at 10 % when dropping under 63° C?

No need for CMD AFAIK, you just drag the slider to the right.

Do you have secure boot disabled?

Sorry, I misread. It's for Linux users only.

https://github.com/hirschmann/nbfc/wiki/First-steps

It's more likely that you have the wrong config file. The 8760W is SEVEN years older than your laptop, not very likely that it will work. Given that it's launched at the same time as my laptop with the same CPU's, your laptop probably has the same EC as mine, pictured above.
