Subject: Buggy DSDT on Dell Latitude E5400
Date: Sun, 14 Dec 2008 03:21:25 +0100 [thread overview]
Message-ID: <20081214022125.GA29259@zen> (raw)
Dear all,
On a recently bought Dell Latitude E5400 laptop with Debian unstable
installed, the fan is constantly working.
This happens although the temperature reported by acpi -v is around 30
degrees Celcius, and although top reports a CPU usage around 1%.
Moreover, when the installed Windows XP is started and the machine is
left untouched, the fan remains turned off all the time.
Are these symptoms the consequence of a buggy DSDT which Windows
overrides ?
In that case, how can the problem be fixed ?
Is it necessary to disassemble and study the DSDT, or is it possible to
somehow fetch the working one presumably used by Windows XP ?
Any help / suggestion warmly appreciated.
Kind regards,
Sebastien.
