摘要： Systems and methods manage use of rechargeable battery power of Information Handling Systems (IHSs). In managing power draws from the batteries of an IHS, use of software applications of the IHS is monitored and use is detected of a software application that has been designated as prioritized for use of the IHS batteries. A power throttling factor is selected for use in drawing power from the rechargeable batteries of the IHS while the prioritized software application remains in use. The selected power throttling factor is transmitted to an embedded controller of the IHS and the embedded controller is notified when the prioritized software application is no longer in use by a user of the IHS. The embedded controller receives the power throttling factor and, while the prioritized software application remains in use, the embedded controller limits power drawn from the IHS rechargeable batteries according to the power throttling factor.

摘要： Embodiments of systems and methods for managing turbo states based upon user presence are described. In some embodiments, a method may include detecting, by an Information Handling System (IHS), a presence state of a user, and modifying a turbo configuration of a component of the IHS in response to the presence state.

摘要： Systems and methods are provided for charging a battery system of an Information Handling System (IHS) using a multimode AC adapter. Information reported by the multimode adapter is used to determine its capabilities, including whether it supports USB-PD transmission and also supports high-power transmissions of a voltage greater than the USB-PD voltages. The charge state of the battery system is monitored. When the battery is in a pre-charge state, the battery is charged using USB-PD transmissions negotiated with the multimode adapter. When the battery is in a bulk-charge state, the battery is charged using a high-power transmission negotiated with the multimode adapter. When the battery is in a top-off-charge state, the battery is charged using USB-PD transmissions negotiated with the multimode adapter. In light of the charging efficiency of a battery varying based on its charge level, the multimode adapter supports efficient charging at different charge levels.

摘要： Systems and methods provide wireless power to an Information Handling System (IHS). A multimode wireless power transmission unit supports USB-PD (Universal Serial Bus Power Delivery) power transmissions and also supports a high-power transmission of a voltage greater than USB-PD transmission voltages. The IHS detects the wireless coupling of the wireless power transmission unit. As part of this coupling, the IHS determines whether the wireless power transmission unit supports high-power transmissions. A wireless power transfer is negotiated and a power circuit of the IHS is configured for converting the negotiated high-power transmission to an input utilized by the IHS. Embodiments utilize a power circuit that provides efficient conversion of power transmissions of up to 60 volts. This same power circuit also provides efficient conversion of power transmissions of up to 60 volts by a multimode USB-C power adapter.

摘要： Systems and methods for managing battery runtime and performance based upon presence detection are described. In some embodiments, a method may include: receiving a first amount of energy from a power source directed to supporting operation of an Information Handling System (IHS); receiving a second amount of energy from the power source directed to charging a battery of the IHS; determining a user's presence state with respect to the IHS; and modifying the first and second amounts in response to the presence state.

摘要： Systems and methods employ an external energy storage device (e.g., intelligent battery pack) interposed between a an information handling system (IHS) and its AC-to-DC adapter. The information handling system may be a fixed compute system, may lack an internal battery and/or may execute an operating system that does not have power management capability. The external energy storage device provides power and power state information to the IHS, e.g., that is based on state of charge (SOC) of the battery and/or absence/presence of AC power. IHS may perform one or more actions based on the power state information such as automatically save data and shutdown when notified AC power is lost and/or SOC is low, and may automatically restart and restore saved data when notified AC power is restored and/or SOC is sufficiently high. The external energy storage device may actively signal or command the IHS to act or may passively supply power state information and let the IHS decide how to act. The information may be provided as different power supply identifier (PSID) values or other types of analog values corresponding to different current levels on a single conductor of a single cable between the external energy storage device and IHS, or may be included in USB vendor-defined messages sent on the single cable.

摘要： 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.
