The Windows 7 operating system produced by Microsoft runs on a wide range of personal computers, including different kinds of laptops. Windows 7 is configurable so that a laptop can run in "clamshell" mode. When a laptop runs in clamshell mode, an external keyboard, mouse and video output, such as a monitor or projector, are used instead of the laptop's own internal components. The laptop continues to run with the lid closed. You can connect the required components and configure Windows 7 to run in clamshell mode on a laptop.
