A portable computer system including a battery, a power switch and a computer unit is provided. The battery provides a supply signal to the power switch. The computer unit includes an embedded controller (EC), a driver and a user interface device. The EC determines whether the battery satisfies a low power condition according to the supply signal. If so, the EC provides a driving supply signal. The driver determines whether the supply signal satisfies a low voltage condition according to the driving supply signal. If so, the driver triggers an alert event. The user interface device triggers a user notification event according to the alert event. The power switch is further turned on/off in response to an operation event for respectively providing the supply signal to power the computer unit and put the computer unit in a power cut-off state. |
