How to show battery status only on laptop?

if a device have no battery, we don't want to display-battery-mode be enabled.[1]

(require 'battery)
(when (and battery-status-function
           (not (string-match-p "N/A"
                                (battery-format "%B"
                                                (funcall battery-status-function)))))
  (display-battery-mode 1))
