The present disclosure provides a display module having a removably fixed retention member that allows disassembly of a computer device, for example, to improve the ease of field repair. The computer device includes a chassis frame forming an outer edge of the device. The chassis frame including a first slot defining a first portion of a keyway, and the display module having a retention member including a second slot forming a second portion of the keyway between the chassis frame and the retention member. The retention element is moveable within the keyway to contact both the retention member and the chassis frame. The computer device may include a compression gasket located between the chassis frame and the retention member. When the compression gasket is held in a compressed state, the first portion and the second portion of the keyway are aligned to allow movement of the retention element.
