Abstract
An apparatus and method for adaptively changing a constant power level of a system in compliance with a current system specification can improve safety issues such as overheating, due to excess charging capacity. After purchase/after market add-ons to the system made by a customer can change the load such that the present invention adaptively changes the constant power level supplied to match the after initial purchase add-ons. The method includes acquiring system specification information, searching for a constant power level corresponding to the acquired system specification information, and changing a constant power level according to the searched constant power level.
Claims18
A method operative in a processing apparatus including a battery and a system, the method comprising:
- receiving a supply of power from an external power adapter to simultaneously charge the battery and supply power to the system;
- acquiring system specification information of at least one system component that has been changed;
- determining a constant power level to be provided to the system based on the at least one system component that has been changed, corresponding to a load level of the at least one system component, wherein the constant power level is a power level at which the power supplied to the battery is decreased;
- and
- controlling the supply of power to the battery and to the system in accordance with the determined constant power level, wherein the system specification information includes information regarding a processing speed of at least one of a Central Processing Unit (CPU), a graphic chipset, and a memory, the load level being determined as a function of the processing speed.
An apparatus comprising a processing system and a battery that receive power from an external power adapter, the apparatus further comprising:
- a controller;
- a system specification information acquiring unit for acquiring system specification information of at least one system component that has been changed;
- a constant power level searching unit for searching for a constant power level to be provided to the system based on the at least one system component that has been changed, corresponding to a load level of the at least one the system component, wherein the constant power level is a power level at which the power supplied to the battery is decreased;
- and
- a constant power level adaptive changing unit for changing a constant power level value supplied to the controller according to the searched constant power level;
- wherein the controller controls the supply of power from the adapter to the battery and processing system in accordance with the changed constant power level, wherein the system specification information is information regarding a processing speed of at least one of a Central Processing Unit (CPU), a graphic chipset, and a memory, the load level being determined as a function of the processing speed.
