    My m4300 is about 10 months old. I have the latest BIOS, win xp SP3, 2GB Ram, 2.00GHz cpu (T7300). I seem to notice the following when the system is docked to an Advanced Port Replicator:

    1. Although Speedstep is enabled in the BIOS, the cpu seems to always stay running at its highest speed (2.00GHz) if it gets there under load.

    2. Once the fan enters into this "fast" state (about 3500 RPM), it appears to stay there even though all temperatures (as reported by I8kfanGUI) seem relatively cool. Typically, I8kfanGUI reports:

    Fan: Fast 3512 RPM
    CPU temp: 39/39 C (core1/core2)
    GPU temp: 50 C
    Memory temp: 54 C
    Chipset temp: 50 C
    HDD temp: 43 C

    I would think these temperatures are relatively cool - so why does the fan stay in the fast state?

    Also why does the Speedstep not clock down the cpu speed when the machine is idle for a while?

    Thanks,
    Harvey
