Do you have the module loaded? # modprobe asus-laptop
It doesn't work.
[root@asus ~]# modprobe asus-laptop
modprobe: ERROR: could not insert 'asus_laptop': No such device
Till not fixed, you can get some information from powertop: # yum
install powertop # powertop
done.
Also in Fedora we have the tuned tool [3]. It can help you to tune
your system for various goals by selecting the right profile. One
of the supported profile is profile targeted to low power
consumption, to enable it: # yum install tuned # systemctl enable
tuned.service # systemctl start tuned.service # tuned-adm profile
powersave
tuned is running - without a significant effect.
I'll send you desg and powertop -html off-list.
Thanks
Uwe
