Hello,
I'll try to be brief, but up to the point.
Problem: I got Toshiba Tecra M3 (notebook). ACPI support is good, but
termal zone lacks tripping points (this I could probably live with)
and fan lacks any control/readings at all (this is annoying since fan
is always on). Fan speed is changing as CPU load/termal zone temp is
changing, but it never completely stops, even if termal zone temp is
as low as 41C.
Desired solution: got some degree of control over fan adn/or termal
zone and be able to make fan silent at least 50% of the time.
What I already did:
I read archives of this list and googled for "toshiba fan", "toshiba
dsdt acpi", etc. I haven't found any useful advice, but I got a lot of
hints. I disasembled my dsdt and looked for "_TZ", "PFN" and
"PNP0C0B". I found only "_TZ", and only in small piece of code:
Scope (\_TZ)
{
ThermalZone (THRM)
{
Method (_TMP, 0, NotSerialized)
{
If (LLessEqual (\_SB.MEM.TMP1, 0x0B4C))
{
Store (0x0B4C, \_SB.MEM.AST1)
Return (0x0B4C)
}
Else
{
Store (\_SB.MEM.TMP1, \_SB.MEM.AST1)
Return (\_SB.MEM.TMP1)
}
}
Method (_CRT, 0, NotSerialized)
{
Return (\_SB.MEM.CRT1)
}
}
}
It seems that there are no references to fan(s) in DSDT at all. Does
this mean that I have no hope and should live with things as they are?
Attached are: dsdt, dsdt disassembly, dmidecode and acpidump outputs.
Hope that this is not too off-topic.
