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


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


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

$ 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
