Hi,
I found this useful extension to limit battery charge and extend battery life. However, it only works on gnome, not on mate. Do you know of a similar extension and/or an easy way to achieve the same purpose?
Thank you
You could try TLP.Easy?That depends on your comfort level with working in terminal I suppose and it will only work if your laptop supports setting a charge threshold but it still may be worth a read.

Hi,
in the meantime I tried with libsmbios which is specific for Dell, but it does not work for my device.
I followed your guide on using TLP. However, I get the following result and my device seems not to be compatible.
sudo nano /etc/tlp.conf
START_CHARGE_THRESH_BAT0=70
STOP_CHARGE_THRESH_BAT0=80
sudo tlp-stat -b
--- TLP 1.6.1 --------------------------------------------

Sorry, can not tell you much. To me your information

reads that generic TLP plugin does not support charge start/end thresholds. 
Please have a look at Battery Care for Dell laptops (Kernel 6.12 required) · Issue #379 · linrunner/TLP · GitHub which hopefully may help.

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
