    Apparently there is/was some support in the works for automatically switchable graphics (I would assume based on currently running applications). I discovered the following functions in ATIs software:
    • ATIDL_PowerXpress_GetAutoSwitchConfig
    • ATIDL_PowerXpress_SetAutoSwitchConfig

    I also discovered the following functions which could be used to write an app that would handle the switchable graphics without using the crash-prone power manager toolbar:
    • ATIDL_PowerXpress_GetActiveGPU
    • ATIDL_PowerXpress_SetActiveGPU

    If only we had documentation of the API for the applicable DLLs then it would be a piece of cake to write some pretty cool apps that would allow you to customize how your switchable graphics behave when docked/undocked, on battery/AC power, etc... When a movie player is running/not running. You could also map a key to switch between graphics.

    From one of ATI's press releases on "PowerXpress":
    If anyone can reverse engineer DLL calls, give me a shout.
