Abstract: The invention provides a power supply including at least one power output port, at least one status alert component, and at least one output port status monitoring module. The status alert component generates at least one visual prompt based on an alert signal. The output port status monitoring module includes at least one temperature sensor adjacent to the power output port, a microcontroller connected to the temperature sensor and sensing an output current from the power output port, and a reset signal generator connected to the microcontroller. The microcontroller comprises at least one port status alert condition that takes a temperature and the output current of the power output port as decision factors. The microcontroller outputs the alert signal to the status alert component when the port status alert condition is met and maintains the status until a reset signal provided by the reset signal generator is received.

Abstract: A keyboard device includes a key structure, a switch circuit board, a base plate and a buffering strip. The key structure includes a keycap and a stabilizer bar. The stabilizer bar is connected with the keycap. A first end of the buffering strip is fixed in a first coupling structure of the keycap. A second end of the buffering strip is fixed in a second coupling structure of the keycap. The buffering strip is contacted with the stabilizer bar and filled in a gap between the stabilizer bar and the first coupling structure. Since the possibility of resulting in the collision between the stabilizer bar and the keycap is minimized, the keycap device is capable of reducing noise.

Abstract: A keyboard and a notebook computer with the keyboard are provided. The keyboard is installed on the notebook computer. The keyboard includes a membrane circuit board, a key frame, a key, a linking rod and a fixing plate. The linking rod is connected with the key frame. The fixing plate is disposed under the key frame. While the linking rod is rotated relative to the key frame to push the key frame, a position-limiting structure of the key frame is moved along a guiding structure of the fixing plate. Consequently, the key frame is limited to be moved in a first axial direction. Moreover, when the key frame is moved to a locked position at the same level with a keycap of the key, the keycap cannot be pressed down.

Abstract: A key structure includes a base plate, a position-limiting structure, a stabilizer bar and a keycap. The position-limiting structure is connected with and fixed on the base plate. A slot is defined by the position-limiting structure and the base plate. The stabilizer bar is connected with the keycap and pivotally coupled to the slot. The position-limiting structure includes a top stopper. The top stopper is made of soft material. As the stabilizer bar is rotated and the stabilizer bar is contacted with the top stopper, the efficacy of reducing noise is enhanced.

Abstract: The present invention provides a keyboard, which includes a plurality of key structures. Each of the key structures includes an elastic piece, a filling piece, a membrane circuit board, and a movable support structure. The elastic piece is used for press by a user to trigger the membrane circuit board. The movable support structure is connected to the filling piece, and is located in an accommodating space defined by the elastic piece, so as to improve an overall structural strength. The elastic piece coats the filling piece and is co-injection molded with the filling piece; hardness of the filling piece is greater than that of the elastic piece, so as to improve hand feelings of pressing the elastic piece.

The first magnetic element is received within the first concave structure. The second magnetic element is received within the second concave structure. The third magnetic element is disposed under the keycap and accommodated within the accommodation space. In response to a first magnetic force between the first and third magnetic elements and a second magnetic force between the second and third magnetic elements, the keycap is protruded out of the opening.
