A power-saving operating method for an electronic device is provided. A control chip of the electronic device has an interrupt pin, and the electronic device couples to a touch device through a connection port and the interrupt pin. When the touch device is idle for over an idle time, a BIOS is informed through the interrupt pin to disable the connection port. When a number of touch signals received from the touch device within a first predetermined time is not less than a first predetermined amount, the connection port is enabled. When the number of the touch signals received from the touch device within the first predetermined time is less than the first predetermined amount or none of the touch signal is received within the first predetermined time, a reading operation for reading the connection port is interrupted and the touch device enters a power-saving mode.

Power saving operating method for an electronic device by disabling a connection port to a touch device before the touch device enters power-saving mode

A booting method is provided. In the booting method, a basic input/output system (BIOS) is activated to check a first set value. When the first set value corresponds to a fast boot mode, the BIOS performs a fast boot process, in which the fast boot process is interrupted when the BIOS receives a system control interrupt. The BIOS changes a second set value and the first set value according to the system control interrupt, so that the first set value corresponds to a normal boot process. Next, the BIOS is reactivated. Further, the BIOS performs a normal boot process when the first set value corresponds to the normal boot mode, in which the BIOS checks the second set value, so as to execute an operating process corresponding to the second set value and recover the second set value and the first set value.
