Abstract: A facsimile apparatus includes a storage unit, a first detection unit, and a second detection unit. The storage unit stores a parameter based on a connection standard of a telephone-line connected to the facsimile apparatus, and an apparatus direct-current resistance of the facsimile apparatus. The first detection unit detects a first voltage that is a voltage at a line-open time of a telephone line connected to the facsimile apparatus. The second detection unit detects a second voltage that is a voltage at a line-capture time of the telephone line. By using the first voltage, the second voltage, the parameter, and the apparatus direct-current resistance, a voltage to be a threshold for determination of line capture is determined. By using a voltage detected from the telephone line and the voltage to be the threshold determined by the first determination unit, whether the telephone line is captured is determined.

Abstract: An information processing apparatus includes a switching unit configured to be an ON-state in which power is supplied to the information processing apparatus and an OFF-state in which power is not supplied to the information processing apparatus, a driving unit configured to set the switching unit to the off-state, a voltage supply unit configured to apply a voltage to the driving unit, and a control unit configured to, in a case where a condition for shutting off the supply of power to the information processing apparatus is satisfied, perform control to apply the voltage from the voltage supply unit to the driving unit, and, after the voltage is applied to the driving unit, control the driving unit to set the switching unit to the off-state.
