I have just investigated the issue further and found out that matchbox
still relies on the old /proc/acpi interface in mb-applet-battery.c:
#define ACPI_PREFIX "/proc/acpi"
#define BAT_PREFIX "battery/BAT0"
#define AC_PREFIX "ac_adapter/AC0"
...
f = fopen(ACPI_PREFIX "/" BAT_PREFIX "/info", "r");
However I fear that things are not as easy as to replace /proc/ACPI/...
with /sys/class/... as I have just noticed that the reference is BAT1
instead of BAT0 on another notebook from me:
cat /sys/class/power_supply/BAT1/status
Full / Discharging
cat /sys/class/power_supply/BAT1/capacity
96 ... means 96% charged
cat /sys/class/power_supply/ADP1/online
1 ... if ac adapter is plugged
0 ... if ac adapter is unplugged
I have also filed an upstream bug at:
