Hello, emacs maintainers.

My laptop battery informations was placed in 
/sys/class/power_supply/CMB0.
But battery.el try to find only /sys/class/power_supply/BAT% series.
So display-battery-mode does not show any battery informations.
Please consider existing different information directories.

Best Regards,

HyungSuk
