A mechanism that prevents premature disengagement of a component from a computer system is provided. Through a graphical user interface, the user signals to logic associated with the computer system to ready a component for removal from the computer system chassis. A trigger recessed in a handle is depressed to mechanically free the handle to pivot from the engaged position outward. The trigger activates a lock, which is coupled to logic associated with the computer system, which is capable of deactivating the lock. The lock prevents disengagement of the component from the computer system by preventing a handle arm, to which the handle is attached, from pivoting outward. When the lock is deactivated, the handle arm is actually free to pivot. When pivoting, the handle arm engages a hub, which rotates as the handle arm pivots. The hub is coupled to a first lever arm which moves and pivots a first engagement member. This engagement member may include a catch which engages insertion and extraction stops mounted on the chassis of the computer system. In one aspect of the invention, the action of the first lever arm and first engagement member may be substantially balanced by a second lever arm and second engagement member. In another aspect of the invention, an indicator light may be provided on or proximate to the component, to signal the user which component is ready for removal, decreasing the chance that the wrong component will be removed.
