PostPosted: Thu May 26, 2005 5:19 pm    Post subject: Powerbook fan Reply with quote

Fan on my powerbook 867 12" is always off...
The computer normally doesnt get *really* hot... but when it compiles it does.
And its gets real hot, but theres no fan.. so im afraid that without the fan going on i would risk some hardware
how do i enable the fan? and also control it?
also how do i see the temperature of my CPU.. maybe i can control the fan to actually start once the CPU gets really hot...

I have an iBook G4, and this is what I do to find the temperature.
Code:
cat /sys/devices/temperatures/cpu_temperature


I'm not sure about your hardware, but on my iBook, I use the module
therm_adt746x which does a pretty nice job of controlling the fan.

Make sure you emerge pbbuttonsd, and cpudynd (slows down CPU to save battery) is a good idea too. Take a look at the etc/conf.d/cpudyn if you want to let it put the hard disk to sleep. I found cpudynd's defaults were sensible and I didn't have to configure it at all. Don't forget to add these daemons to the default runlevel.

Try cat /proc/cpuinfo, it should list the temperature there if you have cpu temperature built into your kernel.

As I told you on IRC yesterday, the ADT 746x support can be found here:
Device Drivers->Macintosh Device Drivers
<*> Support for thermal mgmnt on laptops with ADT 746x chipset

Good luck.

You said on IRC that it was showing as M and you couldn't set it to *? Is that still true? If it is, make sure the module is loaded.
