  1739. APM is a BIOS specification for saving power using several different

  1745. In order to use APM, you will need supporting software. For location
  1746. and more information, read <file:Documentation/pm.txt> and the
  1747. Battery Powered Linux mini-HOWTO, available from
  1748. <http://www.tldp.org/docs.html#howto>.
