Abstract: An information handling system includes a first wireless data communication interface powered by a first power rail, a processor powered by a second power rail, and a second wireless data communication interface powered by the second power rail. When the second power rail is powered off, the first power rail is powered on. The first wireless communication interface determines that the information handling system is within a predetermined distance from a wireless dock, and in response, establishes a first wireless data communication link with the wireless dock, and provides an indication to wake the processor and the second wireless data communication interface. In response to the indication, the information handling system powers on the second power rail, wakes the processor, and establishes a second wireless data communication link between the second wireless data communication interface and the wireless dock.

The embedded controller then receives the relative state of charge of the battery, and provides a relative state of charge indication signal. The battery charge indicator receives the relative state of charge indication signal, and outputs an indication of the relative state of charge of the battery based on relative state of charge indication signal.

Abstract: Systems and methods are provided to implement power supply units (PSUs) that are capable of operating on input power having different types of input voltage waveforms, including, but not limited to, pure sinusoidal waveforms, non-pure sinusoidal waveforms, and non-sinusoidal waveforms. Such a PSU may operate to continue supplying DC output power to a system load as long as the PSU is powered by any one of a variety of such different input power types, while at the same time also effectively monitoring for presence of input power provided to the PSU and shutting down the PSU in event of absence or termination of the input power to the PSU. Such a PSU may also automatically identify and adapt to changes between different types of input power while at the same time continuing to supply DC output power to a system load in an uninterrupted manner for as long as some type of input power is being provided to the PSU.

Abstract: Systems and methods that may be implemented to automatically sense and verify proper mated orientation of a removable BGA package relative to a mating pad array (e.g., of a BGA socket) prior to supplying power to the BGA package. A removable BGA package may be provided with first and second symmetric pins so as to present different respective circuit states on opposing sides of a center point of its BGA package pin array, such that proper orientation of the BGA package occurs only when a designated one of the first and second symmetric pins is mated with a designated pad of the mating pad array. A programmable integrated circuit may in turn sense the circuit state presented at the designated pad to verify proper orientation of the mated BGA package based on the sensed circuit state presented at the designated pad, and may take one or more designated actions based on whether or not proper orientation of the mated BGA package is verified.

Abstract: A key-press detection circuit for an information handling system includes a detector circuit, a RC circuit, and a latch circuit. The detector circuit is coupled to a keyboard matrix device, and operates to provides a clock signal in a first state when a particular key of the keyboard matrix device is pressed and to provide the clock signal in a second state when the particular key is not pressed. The RC circuit receives the clock signal and provides a timed clock signal in a third state for a predetermined amount of time in response to receiving the clock signal in the first state. After the predetermined amount of time, the RC circuit provides the timed clock signal in a fourth state. The latch circuit receives the timed clock signal at a clock input, receives a data signal at a data input, and latches an output signal in a same state as the data signal when the timed clock signal changes from the third state to the fourth state.
