  1708. APM is a BIOS specification for saving power using several different

  1715. and more information, read <file:Documentation/pm.txt> and the
  1716. Battery Powered Linux mini-HOWTO, available from
  1717. <http://www.tldp.org/docs.html#howto>.

  1723. random kernel OOPSes or reboots that don't seem to be related to

  1725. APM in your BIOS).
