Abstract: In an example, a component caddy may include a bracket to receive a computing component; a ground portion disposed on a first end of the bracket to electrically engage with a ground pad; and a connector lock disposed on the ground portion. The connector lock may vertically attach the component caddy to a vertically-oriented connector disposed adjacent to the ground pad on a system board such that the computing component is operably engaged with the connector in a vertical orientation and electrically grounded to the ground pad through the ground portion on the bracket.

Abstract: In some examples, the disclosure describes a connector comprising a cover comprising a cover top, a first clip coupled to a first end of the cover, the first clip including a first lever and a first hook, a second clip coupled to a second end of the cover, the second clip including a second lever and a second hook, and a biasing member coupled to the cover top and disposed between the first clip and the second clip, the biasing member to apply pressure to the connector while the connector is disposed between the biasing member and the first hook and the second hook.

Abstract: Examples of a protection circuit for an interface are described. In an example, the protection circuit comprises an electrostatic discharge (ESD) module. The ESD module suppresses a discharge voltage caused due to an electrostatic discharge. The ESD module may be further coupled to a capacitive element and a resistive element. The capacitive element is to route discharge voltage caused due to an electrostatic discharge, while the resistive element is to route a reverse DC operated voltage.

Abstract: In one example, a computing device may include a circuit board having a contact pad disposed at an edge of the circuit board, and a chassis in which the circuit board is installed. The chassis may include a circuit board holder to engage the edge of the circuit board to retain the circuit board in a defined position relative to the chassis. The circuit board holder may be grounded. Further, the computing device may include a controller to receive a signal from the contact pad, the signal indicative of a presence of the circuit board holder contacting the contact pad. Furthermore, the controller may detect a form factor type of the chassis based on the received signal.

Abstract: Examples of power management apparatuses, computing devices, and methods for disabling a phase of a power supply unit based on a power mode of a computing device are described herein. In an example, upon receiving an indication of the power mode of the computing device from a switching circuit, the power supply unit may disable the phase.

Abstract: An example printed circuit board assembly (PCBA) includes a controller and a plurality of conductive contacts. The conductive contacts are coupled to the controller. The controller is to determine a type of chassis to which the PCBA is mounted.

Abstract: One example provides a system. The system includes a serial port and a circuit coupled to the serial port. The circuit is to detect an installation or removal of a device to the serial port and to remove power provided to the serial port in response to the detection.

Abstract: An audio amplifier is to transition between a power-down mode and an active mode, based on assertion and deassertion of a power down signal. A power down control module is to selectively assert and deassert the power down signal to the audio amplifier. The power down control module may identify at least one of a digital detection signal and an analog detection signal. The digital detection signal indicates the availability of a digital audio signal to be amplified, and the analog detection signal indicates the availability of an analog audio signal to be amplified.

Abstract: Embodiments herein relate to ambient and processor temperature difference comparison. Processor and ambient temperatures are measured. A difference between the processor and ambient temperatures is compared to an initial difference. A warning may be signaled if a difference between the determined difference and the initial difference is greater than a threshold value.

Abstract: A keypad circuit provides a signal corresponding to an actuation of a button. A query is presented to confirm intent to place an apparatus in a low-power state in response to the signal. The apparatus assumes a low-power state in response to a confirmation. The apparatus is also configured to assume an active state from a low-power state in response to the signal. Point-of-sale terminals and other apparatus can be controlled and operated accordingly.
