Abstract: An example electrical connector includes a body to receive a circuit board. The body includes a first end and a second end. The electrical connector also includes a first latch rotatably attaches to the first end. The electrical connector further includes a second latch rotatably attaches to the second end. The electrical connector further includes a link member attached to the body. In response to a rotation of the first latch, the link member is to slide across the body from the first latch towards the second latch to rotate the second latch.

Abstract: Examples of a holding device for retaining an installable component in a chassis of a computing device are described. In one example, the holding device may comprise a longitudinally extending first arm, and a movably coupled second arm. The holding device may further comprise a first engaging portion at first end of the holding device, and a second engaging portion at the second end of the holding device. The engaging portions may couple the holding device to the chassis of the computing device. Furthermore, the holding device may comprise a gripping member. The gripping member is to securely retain the installable component within the chassis of the computing device, and is movable across the length of the holding device.

Abstract: An example non-transitory machine-readable storage medium includes instructions to determine whether a cooling fan is controlled by pulse wave modulation (PWM) or is voltage-controlled. When executed, the instructions cause a processor of a computing device to transmit first and second PWM test signals at different PWM duties to a fan connector connected to the cooling fan, receive a first and second fan speed signals in response, and determine, when the first fan speed signal is not equal to the second fan speed signal, that the cooling fan is a PWM-controlled fan. The instructions further cause the processor to transmit first and second voltage test signals at different voltages to the fan connector, receive a third fan and fourth speed signal in response, and determine, when the third fan speed signal is not equal to the fourth fan speed signal, that the cooling fan is a voltage-controlled fan.
