Abstract: The disclosure provides an electronic device. The electronic device includes a computer system, a light emitting module, and a control unit. The computer system is adapted to execute a boot procedure, the boot procedure lasting for a first time period. A light emitting module includes a plurality of indicator lights, each indicator light providing an indication function. The control unit is electrically connected to the light emitting module. The control unit controls the indicator lights to generate a first light emitting effect within a second time period when the computer system enters the boot procedure.
