NAME

       I8kctl, i8kfan - Utility to access SMM BIOS on Dell Inspiron laptops

SYNTAX

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

DESCRIPTION

       The i8kctl utility provides a command-line interface to the i8k kernel driver for Dell Inspiron laptops. 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.  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 will override 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
