It slowed down the coolers (nearly stopped) when the laptop was doing lightweight stuff, and started them up for full when doing harder work. Allthough, suspend, resume and power off that didn't work at all, but that was good enough for me. I just had to press the power down button for 4 seconds to shut it down. I don't have any serial cable where I'm sitting right now, but hopefully I can arrange a screen capture from the boot with acpi enabled at the end of this week. I also have to mention that I upgraded the bios yesterday, but that didn't do any good either. mvh. Espen
