Hey everyone, I have a no-name laptop that keeps overheating, I'm in need of a BIOS update.

I need the update as I am not able to enable Intel SpeedStep on the machine, I'm on Debian and the output from cat /proc/cpuinfo is blank where it says Power Management. This is with a Pentium M 755 2.0ghz CPU, which most certainly has SpeedStep enabled. Trying to load the speedstep_centrino module fails, as well as everything else I've tried for months now.
In Windows, I only tried XP, the outcome is the same, no cpu-throttling. As a result, the fan is always on and CPU temps are 65-60C when idle.

I have come to believe the problem is caused by a buggy BIOS that somehow fails to supply the OS with information on what kind of cpu-throttling is supported.

Here is everything I know about the machine:

Thank you very much, but I'm afraid there are no BIOS updates released from the manufacturer. I know it sounds stupid, but how impossible would it be to update using a BIOS from another manufacturer, as long as I'm using a PhoenixBIOS for my chipset?

By the way, my machine is NOT an Advent 7040, although is is quite possibly a related model. The 7040 comes with a Celeron-M 1.4GHz CPU, mine is a Pentium M 755 2GHz

The only possible source of info would be Advent. Laptop "manufacturers" that are using OEM boards usually try and hide that fact as good as possible. Often a board is specially build for one or more "manufacturers" with the original factory not releasing a model themselves (Mitac is good at this). So, I'm sorry to say, if Advent never released an upgrade, that is it.
