HP Elitebook 845 G8 - Can't limit battery to 80% charge

[c1arla11]

Hello everyone,

I have got a problem where I have a HP Elitebook 845 G8 and can't set charge limit to 80% (Because most of the time laptop is plugged in and I want to save battery life.
I've installed HP Power Manager and checked the "Maximize My Battery Health" which basically says that this is the way to limit battery charge level to 80%.

In BIOS I also chose a corresponding option as "Maximize Battery Health".

Windows 10 Pro 21H2.

On my old Lenovo Laptop I had such an option in Windows Power Options settings. Here on HP I don't see that option anywhere in Power settings.

Can anyone give me a hint on how can I limit this?

Any help is highly appreciated.
