A portable computer and security operating method thereof are provided to secure the portable computer in a power-off mode. The portable mainly includes a computer host, a system BIOS (Basic Input/Output System), an EC (Embedded Controller), an EC BIOS, one or more input device and a power device, all of which are in bus connection or circuit connection with each other. The EC includes a KBC (Keyboard Controller) and remains activated when the portable computer is in the power-off mode. Meanwhile, the EC is adapted so that in the power-off mode of the portable computer and upon receipt of a security signal, the EC executes a power-off-mode security routine of the EC BIOS to lock the portable computer in the power-off mode. |

1. A security operating method applied to a portable computer, the portable computer having a computer host comprising a CPU (Central Processing Unit), a system BIOS (Basic Input/Output System), an EC (Embedded Controller) in bus connection with the computer host, an EC BIOS, at least one battery, and a power control circuitry controlled by the EC, the EC comprising a KBC (Keyboard Controller), the computer host and the EC being supplied with system power from the power control circuitry in a power-on mode of the portable computer, the method comprising the steps of;
confirming, by the EC, that the portable computer is in a power-off mode, wherein in system power is supplied to the EC but not supplied to the computer host in the power-off mode, such that system power is not supplied to the CPU in the power-off mode; receiving, by the EC, a security signal while the portable computer is in the power-off mode; and on receipt of the security signal while the portable computer is in the power-off mode, executing, by the EC, a power-off-mode security routine of the EC BIOS, wherein the power-off-mode security routine comprises one or more of the steps of the step of disabling input devices, communication ports or USB connectors, or terminating bus connections of input devices, communication ports or USB connectors, while the portable computer is in the power-off mode. |
