Hi
I need help.
I want to change temperature of starting cooling fan, where is this temperature in the bios?
I read the documentation of ACPI but my bios is different.Here is the full: http://www.megaupload.com/?d=Y0CVOQVQ
thx for help!
Sorry for my english

Scope(\_TZ) {
ThermalZone(THRM) {
Method(_TMP,0,NotSerialized) {
If(\_SB.ECOK) {
Acquire(\_SB.PCI0.LPC0.EC0.MUT1,0xFFFF)
Store(\_SB.PCI0.LPC0.EC0.CTMP,Local0)
Release(\_SB.PCI0.LPC0.EC0.MUT1)
Return(Add(Multiply(Local0,0x0A),0x0AAC))
} Else {
Return(0x0C3C)
}
}
Method(_PSV,0,NotSerialized) {
Return(Add(Multiply(0x7D,0x0A),0x0AAC))
}
Name(_PSL,Package(0x01){
\_PR.CPU0
})
Name(_TSP,0x28)
Name(_TC1,0x02)
Name(_TC2,0x03)
Method(_CRT,0,NotSerialized) {
Return(Add(Multiply(0x6E,0x0A),0x0AAC))

Just curious - why do you want to change the temperature?
