Abstract
A computer system having a removable component, such as a removable hard disk drive, and an electromechanical switch that mechanically locks and releases the component. The switch also generates an electrical signal when the component is released. At this point, before the component is physically removed, the central processing unit ("CPU") of the computer executes software that causes the computer system to save what information is necessary for recovery and suspend the system. When the system resumes, the CPU determines whether the component was replaced and, if so, causes an appropriate message to be displayed. The user then may select whether to reset the system or to resume.
