    Mr.Systematic
    Can you share the source code of your great app?

    I'm just not sure that all of this effort is necessary. I had previously been concerned with battery usage (longevity) when using the standard 3 profiles provided by Vista. However, you can make very detailled and specific power profiles that in effect create a dynamic processor environment that minimizes CPU speed so that fan volume is not persistent and irritating. Previously, an 8 cell battery was lasting barely 3 hours and now I am getting much closer to 4 (though still with much feature management and control). Bottom line - undervolting seems to be a hammer vs fly solution.
    Perhaps I am missing something?

    yea we can tweak the power profile but why should we. i mean unless you had planned to buy a 2ghz machine only to run it at 1ghz?

    thanks for your debug .txt file, there148

    If this was the complete output (could be that not all was flushed to the file--open the text file after PumaStateCtrl is terminated) looking into the sourcecode shows that after the processor name is read the CPU type is checked. Maybe 'skip_cpu_type_check="true" ' in XML file helps.

    I do not have an RM-xx CPU so that developing for it is easy. And I don't want to buy / rent etc. some.
    Now I could do the following:
    1. upload (changing a release in sourceforge takes some minutes),
    2. post here that there is a new version
    3. you download and tell me that it still does not work and I begin at "1." again

    That would annoy me (takes too much of my time) and this could result in a bunch of unneeded postings.

    But I had an idea:
    If someone is e.g. highly/ really interested in getting an RM-xx or other CPU similar to ZM-xx working with PumaStateCtrl or has a runtime error, I can do an online session (compile, send .exe, test; communicating via instant messenger, perhaps view-only remote desktop etc.) with him and post THEN if it functions. This is the fastest possibility that came into my mind and I prefer to save time. Btw. compile, send .exe, test is exactly what I do at home--I develop on a PC and send the .exe to the tx2500 via network.

    A second possibility would be asynchronous/non-instant messages via e-mail / private messages.

    I don't want to clutter up this thread with too many of these development infos--it's hard to extract useful infos if someone has to read many postings, I know it from my own experience.

    Send e.g. a Private Message within tabletpcreview forum if you are interested in such an online session/ second possibility.

    If someone has another/ a better idea, tell me.

    hi Mr.Systematic

    after installing windows 7 ( very good os ), i decided to try your software again whilst running in xp sp2 compatibility mode, and the software works. i can't thank you enough. the software works as promised and my voltages are reduced. i immediately saw lower temperatures and less fan activities. thanks ] you've convinced me owning an amd puma cpu wasnt a mistake afterall.

    moderators should pin this thread and software. its very good!

    here are some pics to confirm the software works

    It works on my RM-70 too. (Acer notebook)

    Undervolts from 0.8 to 0.75 on 500 MHz. It seems stable with default settings, maybe it could run even lover? :)

    Great job!;)
