A computer device includes a main casing, a computer body disposed in the main casing, a linkage mechanism including first and second sheets and a first shape-memory alloy, and a movable casing pivoted to the main casing. The main casing is for engaging with the movable casing to position the movable casing at an open position exposed from the main casing. A driving end of the first sheet is movably inserted into a slot of the movable casing. The second sheet is disposed on a recess structure of the main casing and pivoted to the first sheet. The first shape-memory alloy is pivoted to one of the second sheet and the recess structure and the driving end for moving the driving end along the slot when being heated to shorten or elongate to push the movable casing from a closed position contained in the recess structure to the open position.
