Abstract: A lockable enclosure for securing a laptop computer against unauthorized removal comprises a housing having a spring-assisted pivotable cover which automatically locks when closed. The housing accommodates a docking station, and is provided with apertures for routing wiring and cables from the computer to exterior power, data, and communication ports. One embodiment of the lockable enclosure is adapted to be integrally mounted to a worksurface such as for integrated use with a portable laptop computer worktable. Another embodiment of the lockable enclosure is adapted for mounting to the rear of a workspace surface and comprises a movable laptop computer support pan for extending the laptop computer to the front of the workspace surface.
