It seems that battery-linux-sysfs does not support certain laptop
batteries which are not classified as BAT0, but by BATX instead. I had
to add this to my .emacs to get display-battery-mode working properly:

(eval-after-load 'battery
  '(progn
     (setq battery--linux-sysfs-regexp "[bB][aA][tT][xX]$")
     (setq battery-status-function 'battery-linux-sysfs
      battery-echo-area-format "Power %L, battery %B (%p%% charged, remaining time %t)"
      battery-mode-line-format " [%p%%] ")))
(display-battery-mode 1)

Hope this helps, and thanks for all your hard work.
