Hello,

I have a Compaq Laptop Evo N600c and it has now overheated several times.

The fans never come on automatically. I can start them myself with:

echo anything >/proc/acpi/fan/C1F6/state

If I do this, they come on. The machine won't overheat and I can't get them to go back off.

Is there a daemon that monitors various thermal zones and can toggle the fans when necessary?

I have a software in KDE called KLaptop which monitors stuff like the battery. A problem I have though is that the battery never charges more than 98% so it continues charging. How do I stop charging at 97% as not to overcharge the battery?

Thanks,

David

Charging should be something the laptop handles itself. If it is lithin-ion batteries then the system will have its own charging system to charge them at the correct rate and to keep them from totally discharging below lit-ion thrusholds.

As for as the command normally a echo 0 is off and echo 1 is on. Does echo 0 not turn them off?

Unless you can turn off the fan manually since it can be turned on automatically a script of some kind would be of no use if you need for it to turn off. At the very least it can be turned on when the temp limit is reached with a cron file of sorts.

It is possible the laptop is not 100 percent acpi compliant. Have you tried booting with the options apm=on acpi=off or noacpi?

every laptop ive had with linux the kernel always handels this i never have to mess with it. Mabye something isent buit into the kernel or something but i thought that ACPI would handel all that. ive seen some APCI daemons as well.

I happen to have an Evo n600c.

I have ACPI configured in my kernel and it handles my fan fine.

I decided I wanted specific control over my fan so I looked into the acpi scripts.
I have setup my acpi scripts to trigger my fan levels. This information I got from the Gentoo Wiki.
