    How is centrino speedstep work?

    When will 1.5ghz centrino runs on full speed instead of 598mhz?

    Or is it running at 1.5 all this while?

    Here's a link to Intel's site that explains what SpeedStep is/does.

    http://support.intel.com/support/processors/mobile/pentiumiii/sb/CS-007509.htm

    Generally, SpeedStep will run at full speed while connected to AC, but drop to a slower speed on battery to save power. This can also be modified in the Power Management options so the system runs at full speed even on Battery.

    Depending on your Power settings, the CPU may drop to a slower speed even on AC while it's idle (not really working hard), once you need the computing power, it'll automatically jump back up.

    Putting your Power Management option to ALWAYS ON, will have the CPU run at full speed always on AC and battery.
