Information Handling System Battery Charge Management to Support Variable Increased Current Use Functions

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.

主权项

1. A portable information handling system comprising:
a planar housing; a processor disposed in the planar housing and operable to execute instructions to process information; a memory disposed in the planar housing and interfaced with the processor, the memory operable to store the information; a display disposed in the planar housing and interfaced with the processor and memory, the display operable to present the information as visual images; a battery disposed in the housing and operable to power the processor, memory and display; an external power supply operable to power the processor, memory and display, and to charge the battery; a power manager disposed in the housing and operable to manage power applied by the battery and external power supply for powering the processor, memory and display, the power manager further operable to monitor power transition events that exceed power available from the external power supply and to store power consumption information associated with the monitored power transition events; and a battery charge manager interfaced with the power manager, the battery charge manager operable to apply the power consumption information to modify power manager power application at detection of one of the power transition events and a predetermined condition.
