  Log:
  Instead of trusting _STA from power resources, cache the first value
  returned and then infer the state from calls to _ON/_OFF.  This works
  around a problem in systems that don't correctly report the state (i.e.
  the HP Omnibook 500 reports "on" for its fan always after it has been
  turned on once).
