Yes, my laptop arrived safe and sound. Well, mostly safe. It was actually delivered to another address on campus, but it eventually arrived at Afilias.
Tonight, as I wait for the phone to ring, I decide to play with the fan and see if I could shut it off. I can:
# sysctl dev.acpi_ibm.0.fan=0
dev.acpi_ibm.0.fan: 1 -> 0
Checking the temp was easy and pretty soon things jumped from about 48C to just over 60C.
# sysctl -a | grep temperature
Is that too hot? dwhite@ figured it out for me after I pasted:
CPU: Intel(R) Core(TM)2 Duo CPU L7500 @ 1.60GHz (1596.01-MHz K8-class CPU)
The CPU specs indicate that 100C is the thermal specification for this CPU.
BTW, they are now at 67C.
What other things do we have here?
# sysctl hw.acpi.thermal
hw.acpi.thermal.tz0._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1
hw.acpi.thermal.tz1._ACx: -1 -1 -1 -1 -1 -1 -1 -1 -1 -1
Oh, all kinds of neat stuff. Most of which I have no knowledge.
Experimentation shows that dev.acpi_ibm.0.fan_level can vary from 0 to 8, although I find level 1 to be fairly quiet. I can only hear the fan when I’m not typing.
