Mate: Battery Health Charging

Hi,
I saw that the 24.04.3 LTS will come with the 6.14 hwe kernel. So I installed it via PPA and had to add (GRUB_CMDLINE_LINUX_DEFAULT="kvm.enable_virt_at_load=0") to get virtualbox working, but that's another story.
Unfortunately, even installing the latest TLP 1.8.0 via PPA, it doesn't work.

sudo tlp-stat -b
--- TLP 1.8.0 --------------------------------------------
