    My CPU is a Core Duo T2250 (1.73gHZ). Everest showed its CPU Clock speed: 800 Mhz. Why?

    It basically means that all you need most of the time is a 800MHz processor.

    Can I restore its real speed?

    The cpu clock speed changes dynamically depending on the load. So, run something which utilizes cpu then you will see the clock speed increase to the max. Remember to check your power profiles, make sure its either running at balanced mode or if you want it to tun at max always then select the Always On or High performance mode.

    Why do you want to keep it at max speed. You won't really notice a difference with the day-to-day applications you are running. You will just have less battery life.

    Since my battery life only lasts for 2.5 hours (until it self-power off), I alway supply power to it without the battery and that is the reason why I want my machine to run full speed.

    The CPU is able to detect when it needs more power and it ramps up the speed by itself. The performance differences between speedstep and 'full speed' are close to none, besides the extra heat produced.

    As already said make sure you power profile is set to max performance, you will lose battery life but you will get full performance out of it.

    Full speed is just a number. You won't notice any difference in performance since your system will automatically run on full speed when you need it. You will notice more heat as mentioned.
