Just going to drop my 2 cents here. Also a HP laptop that I'd like to see supported. I can also provide any information needed. May be the same as the above since we are both HP.

Vendor:  HP
Product: HP ZBook Firefly 14 inch G8 Mobile Workstation PC
Backend: none detected (no supported battery backend detected)

Thanks for reporting. Unfortunately HP has very limited kernel-level support for charge thresholds on Linux — the hp-wmi driver doesn't expose charge_control_start/end_threshold in sysfs, which is what batctl (and any threshold tool) needs.

Could you both check if the files exist on your systems?

ls /sys/class/power_supply/BAT*/charge_control_*
If they don't exist, it's a kernel/firmware limitation, not something batctl can work around.

A few things to try:

Check BIOS — some HP models have a "Battery Care" or "Adaptive Battery Optimizer" option that limits charge to 80%
Update kernel — newer kernels occasionally add support for more hardware
sudo modprobe hp-wmi — make sure the module is loaded, then check sysfs again
If the sysfs files do appear, batctl's generic backend will pick them up automatically. I'll add HP to the vendor hints in the meantime.
