  • Question

  • Now, Vista suggest: don't use SMI method for display switch and adjust backlight level.

    but now, howto detect activation/attached device(LCD.CRT.TV) for display switch acpi function?

    Intel VGA card's(965GM) activation/attached device status in acpi NVRAM, but where is NV7300/NV7400 device status?

    I use SMI Int10 function to detect device status very slowly.(more than 6 sec)
