摘要： A portable information handling system powered through a docking station charges an internal battery based on available power sensed at the docking station and communicated to a charger of the information handling system. A dock sensor on the information handling system selectively interfaces a local power sensor if the information handling system is not docked or a docking station sensor if the information handling system is docked. Available power sensed at the docking station is communicated to a battery charger of the information handling system by a differential wire pair interfaced through a docking connector.

摘要： An information handling system can receive power from a wireless or wired power source. In response to determining the information handling system is coupled to the wired power source, the system decouples the wireless power source from providing power. In response to the system being decoupled from the wired power source, the information handling system couples the wireless power source to the system.

摘要： A portable information handling system having internal battery power and external adapter power manages power drawn from the external power adapter to avoid exceeding the power rating of the external power adapter. As power drawn from the external adapter approaches a predetermined limit of the power adapter power rating, a power manager of the information handling system alters the operation of the information handling system to reduce power drawn from the adapter, such as by reducing current drawn to charge the battery, enforcing battery optimized mode steps or throttling central processing unit operation. Incremental decreases in power consumption maintain power draw below the external adapter power rating while incremental increases in power consumption have a delay that returns the information handling system to normal operations without excessive oscillation between operating modes.
摘要翻译：具有内部电池电源和外部适配器电源的便携式信息处理系统管理从外部电源适配器抽取的电力，以避免超过外部电源适配器的额定功率。当从外部适配器获取的电力接近电力适配器额定功率的预定限制时，信息处理系统的电源管理器改变信息处理系统的操作，以减少从适配器提取的功率，例如通过减少所需的电流电池，执行电池优化模式步骤或节流中央处理单元操作。功率消耗的增量降低可使功率降低到外部适配器额定功率，而功耗的增加则有延迟，使信息处理系统恢复正常工作，而不会在工作模式之间产生过大的振荡。

摘要： A synchronous Buck voltage regulator accepts an input voltage to provide a regulated output voltage to an information handling system processing component, such as a CPU. Input voltage is regulated by a control MOSFET, a synchronous MOSFET and a regulator controller that controls the output by controlling the control and synchronous MOSFETs. The synchronous MOSFET handles overvoltage events output from the control MOSFET by interfacing an inductor-capacitor tank circuit to reduce the overvoltage. A negative voltage protection MOSFET driver associated with the regulator controller monitors for negative voltage events that result from the interfacing of the inductor-capacitor tank circuit and selectively decouples the inductor-capacitor tank circuit if the negative voltage event is associated with a predetermined condition. The negative voltage protection MOSFET driver maintains the interface of the inductor-capacitor tank circuit if the overvoltage event is associated with a failed control MOSFET.
