    B4.1.5.3 Mobile PC system supports minimum +5V power requirements [Clarification]

    [GRPH-0393.6]

    Mobile PC Note: Mobile systems do not have to supply +5V to the VGA connector at any time. The DVI connector must supply +5V only during boot, when the user first enables external video, and when the system is actually outputting analog or digital video through the DVI connector.

    Some display devices rely on the +5V to power their DDC circuitry, for Plug and Play detection, or both. It is recommended that a mobile PC provide a means to enable the +5V power when necessary.
