  • Publication number: 20180324979
    Abstract: Embodiments of apparatuses and methods are provided herein for characterizing a heat pipe, and for controlling an operating parameter of at least one heat generating component thermally coupled to the heat pipe based on a temperature difference measured across a first section and a second section of the heat pipe. For example, a characterization method is provided for determining at least one threshold value, which can be used to predict heat pipe dry-out within the heat pipe, and a thermal time constant (time lag) between the onset of heat pipe dry-out and a heat pipe dry-out limit. During subsequent system operation, the predetermined threshold value and thermal time constant may be used to extend the performance of the heat pipe to the edge of its cooling capacity.

  • Patent number: 9973027
    Abstract: An information handling system includes a wireless charging receiver, which in turn includes first and second surfaces, a receiver coil, and an isolation marker. The wireless charging receiver is coupled to a back side of the information handling system. The receiver coil is located within the wireless charging receiver and disposed between the first and second surfaces, and receives a magnetic flux field from a transmission coil of a wireless charging pad. The isolation marker is in physical communication with the first surface and aligned with the receiver coil. The isolation marker enables a user to align the receiver coil with the transmission coil of the charging pad, and isolates the magnetic flux field in the receiver coil and away from the user and other components of the information handling system.

  • Patent number: 9748787
    Abstract: A portable information handling system manages battery charge to maintain a minimum level that supports boot by disconnecting the battery from a battery discharge path so that battery charge is lost substantially only to self-discharge. The battery automatically reconnects to the battery discharge path if external power becomes available to charge the battery. The minimum battery charge level provides adequate power in combination with the external power to support boot of the portable information handling system to an operational state. A power manager monitors power transition events to track power consumption information that a battery charge manager applies to modify the power transition events if external power and available battery charge are not sufficient to perform the power transition event without modification.
