Below copy the output of the values obtained by this file: ----------------------------------------------------- $ cat /sys/class/power_supply/BAT0/uevent POWER_SUPPLY_NAME=BAT0 POWER_SUPPLY_STATUS=Unknown POWER_SUPPLY_PRESENT=1 POWER_SUPPLY_TECHNOLOGY=Li-ion POWER_SUPPLY_CYCLE_COUNT=0 POWER_SUPPLY_VOLTAGE_MIN_DESIGN=10800000 POWER_SUPPLY_VOLTAGE_NOW=10938000 POWER_SUPPLY_POWER_NOW=0 POWER_SUPPLY_ENERGY_FULL_DESIGN=60000000 POWER_SUPPLY_ENERGY_FULL=48920000 POWER_SUPPLY_ENERGY_NOW=18790000 POWER_SUPPLY_CAPACITY=38 POWER_SUPPLY_CAPACITY_LEVEL=Critical POWER_SUPPLY_MODEL_NAME=45N1107 POWER_SUPPLY_MANUFACTURER=L POWER_SUPPLY_SERIAL_NUMBER= 4375 ----------------------------------------------------- I had also consulted this file, although it seems that it shows the same information but with a different format: ----------------------------------------------------- $ upower -i /org/freedesktop/UPower/devices/battery_BAT0 native-path: BAT0 vendor: L model: 45N1107 serial: 4375 power supply: yes updated: sáb 25 mar 2017 17:49:46 -03 (57 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging warning-level: none energy: 18,79 Wh energy-empty: 0 Wh energy-full: 48,92 Wh energy-full-design: 60 Wh energy-rate: 0 W voltage: 10,939 V percentage: 38% capacity: 81,5333% technology: lithium-ion icon-name: 'battery-good-charging-symbolic' ----------------------------------------------------- Thanks for your reply.
