Also when I did “echo 45 > /sys/class/power_supply/BAT0/charge_start_threshold” in sudo, it said "bash: /sys/class/power_supply/BAT0/charge_start_threshold: Permission denied "

Hi, thanks for replying ! when I ran, " cat /sys/class/power_supply/BAT0/charge_start_threshold" it turned “cat: /sys/class/power_supply/BAT0/charge_start_threshold: No such file or directory”

Unfortunately I don’t see any settings in the BIOS/UEFI for it, previously when I ran windows 11, I was able to do it with Lenovo Vantage which was a windows only software, Windows 11 was really slow and laggy so that was why I switched out of it.
