laptop battery

Is there a way to read a laptop's battery in processing? Or eventually to see if energy saving mode is active?

I think you cannot do it directly, but you could call platform-specific commands with exec(). For example on OSX this would give you some information that you could parse:

import java.io.InputStreamReader;

String commandToRun = "pmset -g batt";

try {
  Process proc = (Runtime.getRuntime()).exec(commandToRun);

  BufferedReader stdInput = new BufferedReader(new InputStreamReader(proc.getInputStream()));

  String response=null;
  while ((response = stdInput.readLine()) != null) {
    System.out.println(response);
  }
}
catch(Exception e) {
  println(e);
}

sadly I don't have any apple laptop, is there something that works for windows or linux? Or what should I look for anyway?
