Just tried this on my X1 Carbon (i7-3667U Ivy Lake):
# cat /sys/class/power_supply/BAT0/charge_stop_threshold 100 # cat /sys/class/power_supply/BAT0/charge_start_threshold 100
That doesn't seem to make any sense. Is my battery somehow reporting false values here? Any way to cross check these values?
