Subject: ideapad-laptop: cat fan_mode incorrect value on Lenovo S20-30
Date: Fri, 26 Sep 2014 22:38:03 +0200 [thread overview]
Message-ID: <5425CEAB.5040002@Buehmann.de> (raw)
Hi all,
on my new Lenovo S20-30 with automatically loaded kernel module
ideapad_laptop I am able to start interval mode of fan with
echo '1'>/sys/devices/pci0000:00/0000:00:1f.0/PNP0C09:00/VPC2004:00/fan_mode
It is also possible to change it back to normal mode with '0'. But the
result of
cat /sys/devices/pci0000:00/0000:00:1f.0/PNP0C09:00/VPC2004:00/fan_mode
shows 133. All following executions of the same cat command show 5. This
happens every time after the fan_mode has been changed.
This seams to be a bug for me. Here is more about my hardware:

Is it possible to fix this bug?
Kind regards,
Raimar
