[ltp] Not able to modify /proc/acpi/ibm/fan
Tue, 1 Dec 2009 14:29:24 -0500
I would like to do the following two things:
- Keen my fan always running at the maximum speed.
- Keep my CPU running at the maximum speed.
Since I had problems with my LCD, I have connected my thinkpad to a
external display and am using it as a desktop. So fan noise, battery
conservation, etc are a non-issue.
I read in the thinkwiki documentation that
echo level 7 > /proc/acpi/ibm/fan
would make the fan rotate faster. The current output is:
# cat /proc/acpi/ibm/fan
But when I try to write to /proc/acpi/ibm/fan, I get,
bash: echo: write error: Invalid argument
I tried my best searching for a way to modify /proc/acpi/ibm/fan but
wasn't able to get anywhere. So if this post has already been
answered, my sincerely apologies.
