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.
摘要翻译：本文公开了一种用于减少与信息处理系统（IHS）通信的电池中的电流泄漏的方法。该方法包括在电池中提供电池管理单元（BMU），BMU与嵌入式控制器通信，其中BMU包括检测器引脚。该方法还包括：当外部电源耦合到IHS时，将BMU置于待机模式以禁止电池耦合到IHS时从电池到IHS的电力，并且将BMU配置为退出待机模式，以使电池从电池到IHS的电力。还公开了一种信息处理系统（IHS），其包括可操作以启动IHS中的通电顺序的嵌入式控制器和具有电池管理单元（BMU）的电池，其中，BMU最初处于待机模式，禁用IHS的电池电量，BMU与嵌入式控制器通信。该系统还可以包括与嵌入式控制器和BMU通信的电源开关，以及配置为如果外部电源耦合到IHS或者如果电源开关没有外部电源被激活而被接通的控制开关，其中如果所述控制开关被接通，则所述BMU单元退出所述待机模式，由此使所述IHS能够进行电池电力。

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： Methods and systems are described for utilizing multi-mode dongles with peripheral devices. The multi-mode dongles are configured to provide standard mode signals for a standard mode of operation and alternate mode signals for an alternate mode of operation, for example, where a host information handling system is unable to provide the alternate mode signals to the peripheral device. The multi-mode dongle receives mode control signals from a host information handling system and automatically switches from a standard mode of operation to an alternate mode of operation, where the alternate mode signals are provided to the peripheral device, based upon the mode control signals. In one embodiment, the multi-mode dongle can be configured for a universal serial bus (USB) port, and the alternate mode signals can be associated with charging a consumer electronics (CE) device.
