摘要： A portable computer can be “hot” docked to one or more expansion devices, such as a drive wedge and a port replicator. As such, the expansion devices can be connected to and disconnected from the portable computer while portable computer is powered on and fully operational. The portable computer includes control logic that detects when an expansion device is connected to or disconnected from the portable computer and asserts an SMI or equivalent interrupt signal to the computer's CPU to initiate a sequence of events by which the computer determines whether an expansion device has been connected or disconnected. If the CPU determines that the expansion device has been connected to the computer, the CPU appropriately reconfigures itself to communicate with the expansion device. If the expansion device is disconnected, the CPU also appropriately reconfigures itself to preclude communications with the disconnected device.

摘要翻译： 便携式计算机可以“热”对接到一个或多个扩展设备，例如驱动楔和端口复制器。 因此，当便携式计算机通电并且完全可操作时，扩展设备可以连接到便携式计算机并从便携式计算机断开。 便携式计算机包括控制逻辑，其检测何时扩展设备连接到便携式计算机或与便携式计算机断开连接，并向计算机的CPU发出SMI或等效中断信号，以启动一系列事件，通过该事件顺序，计算机确定扩展设备是否已被 连接或断开连接。 如果CPU确定扩展设备已连接到计算机，则CPU适当地重新配置以与扩展设备通信。 如果扩展设备断开连接，CPU也可以适当重新配置自己，以防止与断开连接的设备进行通信。
