A lever assembly for coupling a computer module to a chassis includes a base lever, a locking tab, and a flexible element positioned between the base lever and the locking tab. The base lever is rotatably coupled to the computer module. The base lever is rotatable between an installed position and an opened position. The locking tab is rotatably coupled to the computer module for engaging a locking surface on the chassis when in a locked position. The locking tab is rotatable between the locked position and an unlocked position. The flexible element is configured to bias the locking tab into the locked position when the base lever is in the installed position. Rotation of the base lever to the opened position induces rotation of the locking tab to the unlocked position.
