Newer laptops run the fan continuously, whether on AC or not. My Dell always runs the fan, but it is slow and nearly silent. When the system gets hot, the fan screams at high speed. Finally the CPU will clock down, which cools the system a lot. Then the fan slows down again. > > > Could you point me where can I get my fan to turn off correctly??

This is a good bit of information. ACPI and APM are both enabled by default, so simply checking services isn't going to tell the tale. But when the battstat is good, it's a good bet that power management is happy. Check the following points. I can't offer you a definitive answer, but these might help: Is the laptop hot to the touch? Not all laptops are fitted with "mobile" chipsets, so they run hotter (I learned this the hard way). If that's the case, you'll find the fan running harder and longer. I wouldn't be surprised if that turns into "continuously". Does the system slow down when on battery or after running a while? This may indicate that the CPU is throttled for thermal control. Are there other problems or glitches with the system? CPU's do crazy things when they overheat. If you aren't seeing strange behavior, this also might suggest that the fan is supposed to be on.
