The assembly can be at a first position that causes the first magnet of the display screen unit to attract to the second magnet of the assembly of the base unit to lock the display screen unit. The actuator can receive an electrical pulse when the power switch is selected to power on the foldable computing device and provide a motion to move the assembly to a second position, to cause the first magnet of the display screen unit to be moved away from the second magnet and repulse the third magnet of the assembly in the base unit to unlock the display screen unit.
