imac shuts down alone

[Sebastien Mengin <sebastien@flibuste.net>]

Hi,

I have an Imac running debian sarge 2.4.18.
Sometimes, when we don't use it for a moment, it shuts down completely
without any warning.

There is no power management daemon running on this machine.

We booted this imac on its macos partition and this behaviour
did not occured -- so we guess that the power unit is ok.

Has anyone experienced such a thing? Does anyone know a best way to test
the power unit, in order to be sure it's reliable?

Any help very welcome.

Sincerely,
