# The spindown timeout is set to the value of APMD_SPINDOWN when the
# computer is running on battery power.  When the computer is on AC
# power, the spindown timeout is disabled.  The number specified here
# is encoded in a complicated way.  See the man page for hdparm(8) for
# details.  For small timeouts, numbers between 1 and 240 specify
# multiples of 5 seconds.  So the default value of 18 means 18*5=90
# seconds, or 1.5 minutes.
