Abstract: Examples disclosed herein relate to a device that has a chassis that can transition from a factory security state to a production security state. A visible object can be removed from the outside of the chassis to trigger the change in state. A BMC can change the state from the factory security state to the production security state based on detection of a physical trigger. The factory security state includes an application programming interface (API) that is enabled and the production security state has the API disabled.

Abstract: According to an example, to repair a disk drive error, a determination is made if a disk field-repair is possible, if an operating system recovery image is available, and if any failed sectors exist in the operating system recovery image. A user is prompted to begin a repair. Failed sectors on the disk drive are read and overwritten, and an operating system recovery is started. In some examples, the disk drive error is an uncorrectable disk drive error.

Abstract: Example embodiments relate to testing of a battery of a computing device. In example embodiments, a battery test may include determining whether charge control is available for a battery and reading battery data from the battery based on whether charge control is available for the battery. In addition, in example embodiments, the battery test may include determining whether the battery should be replaced based on the battery data.

Abstract: A computing device executes a boot process. During boot process execution, the computing device initiates automatic calibration of a battery connected to the computing device.

Abstract: A method and system for performing parallel tasks in a computer system includes invoking a single-threaded operating environment in a computer, invoking under the single-threaded operating environment a first task to be performed by a first processor, invoking under the single-threaded operating environment a second task to be performed by a second processor, while the first task is still being performed, and receiving results from the first and second tasks.

Abstract: Disclosed embodiments relate to an electronic device including a processor and a machine-readable storage medium, which may include instructions for testing an electronic device, including instructions for executing an executable and instructions for signaling the executable to initiate a test on an electronic device. The machine-readable storage medium may also comprise instructions for receiving information from the executable about the test before the booting of an operating system on the electronic device and before the executable finishes executing.

Abstract: A shallow open top sheet metal housing contains thermal insulating material on its side and bottom walls and is covered by a translucent top panel beneath which a multiplicity of translucent tubes in side-by-side contacting relationship provide dead air insulation. Serpentine copper tubing topped by a blackened flat copper sheet is arranged in a plane below and parallel to the plane in which the translucent tubes are positioned. The serpentine copper tubing is adapted for connection with a heated fluid circulating system externally of the collector. In a modification, a Fresnel lens concentrates solar rays on the copper tubing.
