    Does the vaio TZ automatically throttle if I have done a clean install of XP (from portable one)? Or do I need RMclock or similar? Can vaio power management handle CPU throttling?

    run rmclock without enabling any special configuration, and see if the cpu is throttling, that will answer your question.

    Hmm, I guess its not throttling. Is there an official sony or intel app that handles the throttling on plug/unplug? I remember in my older sony SRX99P there was power panel that did this (or at least showed it). This old laptop had a PIII with speedstep.

    Also does throttling the CPU necessarily improve battery life? What are benefits of throttling?

    Sure, the CPU will throttle down when doing non-intensive CPU tasks. For example, I don't need the full speed of my 1.06ghz processor when doing something like reading a word document. So it clocking down to a lower speed will save battery life, give less heat, etc.

    Celeron processors cannot throttle and that is one big reason for them having lower battery life than the Pentium/Core counterparts.

    Rahul: are you using RMclock or other software? Thanks

    I did on my previous laptop, I wonder why I haven't on my TZ? Just never crossed my mind, I've had my mind on finals right now. :)

    Most recent Intel CPU's will run at half speed while not under load without any intervention. CPUZ is another utility that will show processor clock speed and voltage. Nrmal behavior is to go to full speed in a few steps under load.

    Some settings of the Sony power manager (and "battery saver" settings under Vista) will allow the CPU to go to full speed momentarily under load but throttle back after a few seconds. This allows for brief responsive behavior, but keeps a continued heavy load from "burning" things up.

    The power saver setting on the Sony XP power management software locks the CPU at half speed.
