Abstract: In one example, an electronic device may include a main body, and a back cover having an opening. The back cover may include an inner surface, and a hook protruding from the inner surface. The hook may be engageable with a receiving portion of the main body to slidably couple the back cover to the main body. Further, electronic device may include a component housing connected to the main body through the opening in the back cover to fixedly couple the back cover to the main body.

Abstract: In some examples a computing device can comprise a back plate and an electrical connection. The electrical connection is not in contact with a detect mechanism if a first voltage is generated; and the detect mechanism is in contact with the electrical connection if a second voltage is generated.

Abstract: An apparatus may include a collar, a first bracket and a second bracket. The collar may be retained in a substrate through hole of a substrate. For example, a portion of the collar may be inserted into the substrate through hole. The first bracket may include a first bracket screw hole and the second bracket may include a second bracket screw hole. The second bracket may be adjustable from a first (down) position to a second (upright) position. When the second bracket is in the first position, a mount retaining screw may be received through the first bracket screw hole to retain a mount to the substrate for a first thickness of the substrate. When the second bracket is in the second position, the mount retaining screw may be received through the second bracket screw hole to retain the mount to adjust to a second thickness of the substrate.

Abstract: A detection device includes: a body; a first set of at least three contact areas on the body to contact a corresponding set of at least three contact areas of a central processing unit (CPU) cover; and a second set of at least three contact areas on the body to contact a set of at least three contact areas on heatsink componentry. An incorrect assembly position of a heatsink is indicated when one or more points of contact with the heatsink componentry and the CPU cover is incorrect.

Abstract: In an example, a movable lock may include a lock bar and a pivot disposed at a first end of the lock bar. The movable lock may also include a card retainer disposed on the lock bar at a second end of the lock bar, opposite the first end. The card retainer may include a card notch sized to receive an edge of a system card.

Abstract: An example disclosed herein is a non-volatile storage medium including instructions relating to control of power that, when executed by a processor, cause the processor to monitor a supply of power to a regulator, decouple supply of power to the regulator when the monitored supply of power is below a predetermined level, couple a power pack to the regulator to supply power to the regulator when the monitored supply of power is below the predetermined level, and generate an Advanced Configuration and Power Interface (ACPI) G1 Sleeping state signal when the monitored supply of power is below the predetermined level.

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: 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.

Abstract: Circuits for preventing power drawn by a load from exceeding a threshold are provided. A first circuit monitors power supplied to the load and disables a power supply if a threshold is exceeded. A second circuit disconnects the load from the power supply if the threshold is exceeded.
