An exemplary motherboard fixing device is for fixing a motherboard onto a case plate inside a computer case. The motherboard fixing device is fixable on the case plate, and includes a first fixing strip and a second fixing strip. The first fixing strip includes a first, second, and third flat plates. The second flat plate is between the first and third flat plates. The first and second flat plates cooperatively define a slide groove for receiving an edge of the motherboard. The second fixing strip includes a bottom plate and a lateral plate. The third flat plate and the bottom plate include first latch hooks. The first latch hooks is engagable in corresponding through holes of the case plate, such that the first and second fixing strips are fixed on the case plate. The lateral plate includes second latch hooks for being latchable on an opposite edge of the motherboard.

An enclosure includes a bottom plate, and a plurality of slide assemblies fixed to the bottom plate. Each of the plurality of slide assemblies includes a fixed member fixed to the bottom plate, and a rotary member rotatably received in the fixed member. The rotary member includes first and second fixed portions, and a wheel. The first fixed portion is fixed to the second fixed portion, the second fixed portion is connected to the fixed member, and the wheel is fixed to the first fixed portion. Each rotary member is operable to be in a first position to expose the respective wheel for moving the enclosure, and in a second position to be received in the respective fixed member.

A Registered Jack-45 (RJ-45) connector assembly includes an RJ-45 connector, and an assisting apparatus for unplugging the RJ-45 connector. The RJ-45 connector includes a slanted resilient latch. The assisting apparatus includes a latching portion and a pressable portion. A receiving slot is defined in the front end of the latching portion, to engage with the resilient latch of the RJ-45 connector. When the pressable portion is pressed, the assisting apparatus drives the resilient latch of the RJ-45 connector to deform and disengage from a connector of an electronic device.

An exemplary server center includes a server, a heat dissipating system, and temperature controlling device. The heat dissipating system includes an exhaust fan, and an airflow tunnel connecting the exhaust fan with the server. The temperature controlling device includes a temperature sensor electrically connected to the server, and an airflow valve mounted on the airflow tunnel. The temperature sensor is configured for detecting a temperature of the server and controlling the airflow valve to permit the airflow enter the airflow tunnel or not, according to the temperature obtained from the server.

A server rack includes a main body, an electronic scale, and an alarm. The main body is used for receiving a number of servers. The electronic scale includes a pressure sensor and a microcontroller. The main body presses on the pressure sensor so that the pressure sensor can measure the pressure from the main body to obtain a pressure signal. The microcontroller analyzes the pressure signal to calculating the total weight of the main body and the servers. The alarm stores a predetermined weight threshold, which is the total weight of the main body and the maximum servers that the main body can bear. The alarm also compares the measured total weight with the predetermined weight threshold. When the measured total weight is larger than the predetermined weight threshold, the alarm alarms.

A keyboard includes a plug communicating with an external input device, a printed circuit board (PCB), and a base. The PCB includes a first power pad and a second power pad electrically connected to the plug via a cable. The PCB outputs a control signal to the plug via the cable in response to the first power pad and the second power pad being electrically connected. The base includes a control and at least one positioning element for positioning the control on the base. The control includes a pushbutton, a first pin electrically connected to the first power pad, and a second pin electrically connected to the second power pad. The first pin and the second pin are electrically connected in response to the pushbutton being pressed.

A keyboard includes a keyboard body, a first resistor, a first capacitor, a jumper block mounted to the keyboard body, a battery, a keyboard interface, and a keyboard control circuit. The jumper block includes a grounded first pin and a second pin. The battery includes a positive terminal grounded by the first resistor and the first capacitor connected in series, and a grounded negative terminal. The keyboard interface includes a data pin, a voltage pin, and an idle pin. The idle pin is connected to a node between the first resistor and the first capacitor, and connected to the second pin of the jumper block. The keyboard control circuit is connected to the data pin to transmit data, and connected to the voltage pin to receive a voltage.
