All attached files were taken with 100% charged battery and AC power supply connected. > energy: 0 Wh
What's the output of:
cat /sys/class/power_supply/BAT0/energy_now
?

Unfortunately, nothing meaningful:
$ cat /sys/class/power_supply/BAT0/energy_now
cat: /sys/class/power_supply/BAT0/energy_now: No such file or directory
It's the same laptop, but now slightly different distro:
Debian testing "jessie" / amd64
Linux 3.10.7 (3.10.7-1)
upower 0.9.21 (0.9.21-2)
The ACPI for that laptop seems pretty broken: POWER_SUPPLY_CHARGE_NOW=-1000 You should report this as a bug against the kernel at bugzilla.kernel.org. The laptop lacks energy_* information. Reopen this bug if the kernel developers think that this is actually a bug in UPower. It turns out that this was indeed a bug in upower and is resolved in arch linux package upower version 0.9.23-2 The upstream report for this is at https://bugs.freedesktop.org/show_bug.cgi?id=70952 So this I believe is now fully resolved with the latest upower version. |
