    Hi there,
    I have a problem with my Stamina>Speed switch in Windows 7. Here is the scenario:
    - I did a clean XP install (formatted the whole hdd). I took the original driver from Sony support and everything worked like a charm. Switching from Stamina to Speed and the other way was no problem with a reboot.

    -Than I did a clean W7(64bit) install. I used a original Copy from Microsoft not something from Sony. I took the original drivers from Sony support and accept from the Alps Pointing Device (some error "Wrong OS" :confused: ) did it work. Switching from Stamina to Speed or the other way also worked.

    After I startet XP for the first time (after W7 installation) somehow W7 isnt able to switch the graphic card anymore. Also the light above the switch doesn't work anymore. W7 always runs the Intel card (looked at dxdiag).

    By the way the reboot isn't like it was before. It seems to me like the system is shutting down completely and turns on after a few seconds. (Makes this klick sound like you can hear when you force the notebook to shut down by pressing the power-button for a while). Have no idea what this supposed to mean..

    Sorry for my english.. :D and thanks for any help in advance.
