temperature sensor powers off ibook?

[Joerg Sommer <joerg@alea.gnuu.de>]

Hi,

since two weeks my iBook is often powered off after I went to outdoor
with it. This is the first winter since the kernel supports sleep mode
for my iBook G4. I don't have any other explanation for this phenomenon
than there is a temperature sensor in the iBook that shuts it down (while
it sleeps) when the temperature is to low. Is this true?

I have nothing changed in the kernel or the kernel itself before this
problems start and I see it only when I was outdoor. I carry my iBook
only in a second skin and a backpack. Did anyone have the same problems?

Have a nice weekend, Jörg.
