How do you remove the Laptop from the docking station?. Are you shutting the PC down prior to removing it? Are you just physically removing it? Or are you using an &quot;Undock&quot; feature in your OS (On some it is an addition to the shutdown menu, on others it can be similar, or is the &quot;Safely Remove tool in the Taskbar)?<br />

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
