INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract There is provided an information processing apparatus including a mode control unit configured to perform control at least so as to switch a first mode that causes the information processing apparatus to be operated at a first voltage level and a second mode that causes the information processing apparatus to be operated at a second voltage level higher than the first voltage level, and an operation control unit configured to disable certain input operation performed by a user if a state satisfies a certain condition after the mode control unit switches a mode to the second mode. ## Claims ### Claim 1 An information processing apparatus comprising: a mode control unit configured to perform control at least so as to switch periodically between a first mode that causes the information processing apparatus to be operated at a first voltage level and a second mode that causes the information processing apparatus to be operated at a second voltage level higher than the first voltage level and lower than a third voltage level of a third mode corresponding to a running state of the information processing apparatus; and an operation control unit configured to disable certain input operation performed by a user if a state satisfies a certain condition after the mode control unit switches from the first mode to the second mode, wherein the certain input operation is a switching from the second mode to the third mode, and wherein the mode control unit and the operation control unit are each implemented via at least one processor. ### Claim 2 (depends on 1) The information processing apparatus according to claim 1, wherein, in a case where the mode control unit switches from the first mode to the second mode in a certain periodic cycle, the operation control unit disables certain input operation performed by the user on a condition that the information processing apparatus is operating in the second mode, as the certain condition. ### Claim 3 (depends on 2) The information processing apparatus according to claim 2, wherein the first mode corresponds to a sleeping state. ### Claim 4 (depends on 1) The information processing apparatus according to claim 1, wherein the operation control unit disables certain input operation performed by the user on a condition that the information processing apparatus is operating in a state where a display is off, as the certain condition. ### Claim 5 (depends on 4) The information processing apparatus according to claim 4, wherein, in the case where the information processing apparatus is operating in the state where the display is off, the operation control unit disables the certain input operation if the information processing apparatus is not in a certain state. ### Claim 6 (depends on 1) The information processing apparatus according to claim 1, wherein the operation control unit performs control in a manner that an input operation not to be disabled exists even if the state of the information processing apparatus satisfies the certain condition. ### Claim 7 (depends on 6) The information processing apparatus according to claim 6, wherein the input operation not to be disabled is input operation to a power button. ### Claim 8 (depends on 1) The information processing apparatus according to claim 1, wherein the mode control unit causes communication processing with external equipment to be executed when causing the information processing apparatus to be operated in the second mode. ### Claim 9 (depends on 1) The information processing apparatus according to claim 1, wherein the operation control unit stops power supply to a device on which input operation is performed when certain input operation performed by the user is disabled. ### Claim 10 (depends on 1) The information processing apparatus according to claim 1, wherein the operation control unit disables input from a device on which input operation is performed when certain input operation performed by the user is disabled. ### Claim 11 (depends on 1) The information processing apparatus according to claim 1, wherein the operation control unit determines an exposure state of a display and then determines whether the certain condition is satisfied. ### Claim 12 (depends on 11) The information processing apparatus according to claim 11, wherein, in a state where the display is exposed, the operation control unit determines whether the certain condition is satisfied. ### Claim 13 An information processing system comprising: a display unit configured to display information; a mode control unit configured to perform control at least so as to switch periodically between a first mode that causes an information processing apparatus to be operated at a first voltage level and a second mode that is a state where the display unit does not display information and that causes the information processing apparatus to be operated at a second voltage level higher than the first voltage level and lower than a third voltage level of a third mode corresponding to a running state of the information processing apparatus; and an operation control unit configured to, if a state satisfies a certain condition after the mode control unit switches from the first mode to the second mode, disable certain input operation performed by a user, the certain input operation switching from the second mode to the third mode where the display unit displays information, wherein the display unit, the mode control unit, and the operation control unit are each implemented via at least one processor. ### Claim 14 A power control method, implemented via at least one processor, the method comprising: performing control at least so as to switch periodically between a first mode that causes an information processing apparatus to be operated at a first voltage level and a second mode that causes the information processing apparatus to be operated at a second voltage level higher than the first voltage level and lower than a third voltage level of a third mode corresponding to a running state of the information processing apparatus; and disabling certain input operation performed by a user if a state satisfies a certain condition after the first mode is switched to the second mode, wherein the certain input operation is a switching from the second mode to the third mode.
