AC Power

As previously stated, the battery is used to provide direct current to your notebook and the battery is then recharged by the AC adapter that connects your laptop to the wall outlet. While the battery directly powers the notebook’s components, much like a power supply in a desktop, the battery doesn’t perform any transformation of the power it receives or sends out. These functions are handled by the AC adapter. Many docking stations provide the ability to either use the regular AC adapter as their power source, or use a built-in AC adapter to perform the transformation of the power from AC to DC. If the laptop is using a docking station, it still uses the battery to provide power to the laptop, and the docking station to charge the laptop’s battery. A port replicator , on the other hand, requires the AC adapter to perform the transformation for it.

如前所述，電池用於向筆記本計算機提供直流電，然後通過將筆記本計算機連接至牆上插座的交流適配器為電池充電。 儘管電池可以直接為筆記本計算機的組件供電，就像台式機中的電源一樣，但是電池不會對其接收或發出的電能進行任何轉換。 這些功能由交流適配器處理。 許多擴展塢都可以使用常規的AC適配器作為電源，也可以使用內置的AC適配器執行從AC到DC的電源轉換。 如果筆記本電腦使用的是擴展塢，它仍會使用電池為筆記本電腦供電，而擴展塢則使用筆記本電腦的電池充電。 另一方面，端口復制器需要AC適配器為其執行轉換。

Docking stations are used to add capabilities to a laptop and create a "desktop" experience. For example, in the image above, you can see that the docking station has numerous USB ports, a PS/2 port for keyboard/mouse, a modem port, Ethernet port, VGA and DVI display outputs, audio input and output ports, as well as serial and parallel connections. Some docking stations even have built-in hard drives and optical drives for additional storage. A port replicator, on the other hand, only provides the same ports that already exist on the laptop. This is used for quick connection and disconnection to the various external devices when the laptop is returned to the office environment.

擴展塢用於向筆記本電腦添加功能並創建“桌面”體驗。 例如，在上圖中，您可以看到擴展塢具有許多USB端口，一個用於鍵盤/鼠標的PS / 2端口，一個調製解調器端口，以太網端口，VGA和DVI顯示輸出，音頻輸入和輸出端口，如 以及串行和並行連接。 某些擴展塢甚至具有內置硬盤驅動器和光盤驅動器，用於額外存儲。 另一方面，端口復制器僅提供筆記本電腦上已經存在的相同端口。 當筆記本電腦返回辦公環境時，可用於快速連接和斷開與各種外部設備的連接。
