A power surge detection device is disclosed to investigate if there is any power surge occurring to a main processor in a computer system. When the width or frequency of power surges detected jeopardize the normal operation of the computer system, an alerting signal, for example, an interrupt signal or a power management signal, is sent to the main processor to intervene in the normal operation of the computer system so as to avoid the power instability period.

[ What is claimed is:] [1.]1. A power surge detection device for detecting power surges from a power source, comprising:a power source, external to the power surge detection device, for use with a high frequency device;a control circuit, responsible for monitoring operations of the power surge detection device;a high-speed voltage detection circuit controlled by a voltage-controlled signal from the control circuit, wherein a detection signal from the high-speed voltage detection circuit is activated when a power surge from the power source occurs based on the voltage-controlled signal; anda counter connected to both the high-speed voltage detection circuit and the control circuit for enumerating the number of times that power surges have occurred.
