摘要： A method for managing an alternating current adaptor system is disclosed. A direct current voltage is received at a high impedance power delivery network from a primary side of an alternating current adaptor system. An isolated voltage is output from the high impedance power delivery network to components of a secondary side of the alternating current adaptor system. A transition in a power state identification of an information handling system associated with the alternating current adaptor system is detected. An output voltage level of the alternating current adaptor system is alternated in response to the transition in the power state identification of the information handling system.

摘要： For improving efficiency of a power device having an exposed surface capable of radiating energy, a shielding layer is disposed in between the exposed surface and a conductive layer. The shielding layer causes at least a portion of the energy to be directed back into the power device, thereby substantially preventing the energy from inducing eddy currents in the conductive layer. The conductive layer is fabricated from a metal foil for compliance with electromagnetic energy leakage regulations.

摘要： A method for reducing current leakage in a battery in communication with an information handling system (IHS) is disclosed herein. The method includes providing a battery management unit (BMU) in the battery, the BMU in communication with an embedded controller, wherein the BMU comprises a detector pin. The method further includes placing the BMU in a standby mode to disable power from the battery to the IHS while the battery is coupled to the IHS, and configuring the BMU to exit the standby mode, if an external power supply is coupled to the IHS, to enable battery power from the battery to the IHS. Also disclosed is an information handling system (IHS) which includes an embedded controller operable to initiate a power-on sequence in the IHS, and a battery having a battery management unit (BMU), wherein the BMU is initially placed in a standby mode to disable battery power to the IHS, the BMU in communication with the embedded controller. The system may further include a power switch in communication with the embedded controller and the BMU, and a control switch configured to be switched on if an external power supply is coupled to the IHS or if the power switch is activated without the external power supply, wherein the BMU unit exits the standby mode if the control switch is switched on, thereby enabling battery power to the IHS.
