| 发明名称 | Controlling a current drawn from an adapter by a computer system | ||
| 摘要 | The disclosed embodiments provide an apparatus that controls a current drawn from an adapter by a computer system. During operation, the apparatus senses the current drawn from the adapter using a first current sensor and a second current sensor, wherein a response time of the first current sensor is faster than a response time of the second current sensor. Then, when the current sensed using the first current sensor exceeds a predetermined high-current threshold, the apparatus limits the current drawn from the adapter to a first predetermined current limit. Additionally, when the current sensed using the second current sensor exceeds a predetermined thermal-limit current, the apparatus limits the current drawn from the adapter to the predetermined thermal-limit current. | ||

| 主权项 | 1. A method for controlling a current drawn from an adapter by a computer system, comprising: sensing the current drawn from the adapter using a first current sensor; sensing the current drawn from the adapter using a second current sensor, wherein a response time of the first current sensor is faster than a response time of the second current sensor; when the current sensed using the first current sensor exceeds a predetermined high-current threshold, limiting the current drawn from the adapter to a first predetermined current limit; and when the current sensed using the second current sensor exceeds a predetermined thermal-limit current, limiting the current drawn from the adapter to the predetermined thermal-limit current. | ||
