NAME

       I8kctl, i8kfan - Utility to access SMM BIOS and DMI table information from Dell laptops

SYNTAX

       i8kctl [<command> [<args>]]
       i8kfan [<left> [<right>]]

DESCRIPTION

       The  i8kctl  utility  provides  a  command-line  interface  to the i8k kernel module. When
       invoked without arguments the program reports the same information which can be read  from
       the /proc/i8k file:

              1.  i8k format version
              2.  bios version
              3.  service tag (later 'machine id')
              4.  cpu temperature
              5.  left fan status
              6.  right fan status
              7.  left fan speed
              8.  right fan speed
              9.  ac power status
              10. fn buttons status

       The  optional  command argument can be used to select only one of the above items. Command
       can be: version, bios, id, temp, fan, speed, ac and fn. Examples:

              $ i8kctl
              1.0 A17 B5W123K 52 2 1 8040 6420 1 2

              $ i8kctl temp
              52

              $ i8kctl fan
              2 1

       The fan command can accept two optional parameters which specify the  new  fan  state  for
       left and right fans. The state parameter can be:

              0  turn the fan off
              1  set low speed
              2  set high speed
              -  don't change the state of this fan

       For example the command:

              $ i8kctl fan - 2

       sets  the  right fan to high speed and leaves the left unchanged.  It should be noted that
       if the i8kmon(1) daemon is used to control the fans, setting  the  speed  with  i8kfan  is
       pointless since the daemon override regularly the speed with its own value.

       Invoking i8kctl as i8kfan is the same as invoking the program with the fan option:

              $ i8kctl fan 1 2
              1 2

              $ i8kfan 1 2
              1 2
