1. A power management method of a computer system, comprising:
- capturing a current remaining capacity of a battery and reading a previous remaining capacity of the battery from a register;
determining whether the current remaining capacity is equal to the previous remaining capacity;
determining whether a voltage turbo boost (VTB) function of a smart charger is enabled if the current remaining capacity is not equal to the previous remaining capacity, wherein the VTB function controls the battery to provide power;
determining whether the current remaining capacity is smaller than a disabling threshold if the VTB function is enabled; and
disabling the VTB function and enabling a system constant power protection function if the current remaining capacity is smaller than the disabling threshold, wherein after the system constant power protection function is enabled, and if a total power consumption of the computer system is smaller than the system constant power protection point, a system constant power protection point is set to be smaller than a constant power of an AC adapter and the battery performs charging.

Abstract
A computer system and a power management method thereof are disclosed. The computer system comprises a smart charger and an embedded controller (EC). The smart charger has a voltage turbo boost (VTB) function. The EC enables or disables the VTB function to protect a battery from damage according to a current remaining capacity and a battery decline ratio of the battery.
