Hi Michael
Thanks for your feedback and suggestions !

You are correct with pointing problems to ACPI but 
your pointing to "bad" BIOS may not be coorect !? ;-)

ACPI:
Well, I had a "sensor setting error" while booting and removed all ACPI
stuff !
Since then the error message is gone but not the heating problem !!
Very soon I have to do a complete new installation from scratch with
8.04 
and will see later again with this new setup if the problem persist !?

BIOS:
The notebook is maintained very well with IBM / Lenovo's Update
Service/s !!
BIOS is most accurate I had no heat problems before i installed
Ubuntu !!!
So, this shouldn't be the case !?
