Chciałbym być miły dla aku bo laptop pracuje prawie 100% czasu na kablu 
i ograniczyć pojemność, do której ma być ładowany.

Czytam, że robi się to na tym:
/sys/class/power_supply/BAT0/charge_control_start_threshold
/sys/class/power_supply/BAT0/charge_control_end_threshold

Ale wszystko co mam u siebie to:
root@agatek-inspiron:/sys/class/power_supply/BAT0# ls -la
total 0
drwxr-xr-x 4 root root    0 Jul  6 21:05 .

-r--r--r-- 1 root root 4096 Jul  6 21:05 voltage_now

Utworzyć zwyczajowymi sposobami tego nie mogę (mimo, że guglam, że tak 
właśnie się robi): 

root@agatek-inspiron:/sys/class/power_supply/BAT0# echo 85 > /sys/class/power_supply/BAT0/charge_control_start_threshold; echo 90 > /sys/class/power_supply/BAT0/charge_control_end_threshold
-bash: /sys/class/power_supply/BAT0/charge_control_start_threshold: Permission denied
-bash: /sys/class/power_supply/BAT0/charge_control_end_threshold: Permission denied

Jak się to powinno zrobić?
