  • Publication number: 20210141438
    Abstract: Methods that can transition between multiple operating states are disclosed. One method includes monitoring an amount of power consumed by an information handling device operating in an idle state after transitioning from an active state to the idle state, transitioning an operating state of the information handling device to the active state in response to detecting that the amount of power consumed by the information handling device in the idle states exceeds a predetermined power consumption threshold value, and causing the operating state of the information handling device to transition back to the idle state subsequent to transitioning to the active state. Apparatuses and computer program products for performing the method are also disclosed.

  • Patent number: 10901477
    Abstract: An information processing apparatus includes a first controller which is in an active state regardless of whether a state of a computer system is the active state or an idle state and a second controller which is in the active state in a case where the state of the computer system is the active state, a first low power consumption mode or a second low power consumption mode and is in the idle state in a case where the state of the computer system is a third low power consumption mode are provided. The first controller freely counts a time of day and changes the state of the computer system to the first low power consumption mode in a case where the state of the computer system is the third low power consumption mode and the time of day reaches a predetermined transition time of day.

  • Publication number: 20190339764
    Abstract: An apparatus for controlling power efficiency of an information processing device is disclosed. The apparatus includes a voltage converter that converts a selected input voltage into a predetermined output voltage, an information processing device that uses power supplied by the voltage converter; and a controller that determines the selected input voltage based on an operating state of the information processing device where the operating state includes one or more parameters selected from fan speed, power consumption, power consumption fluctuation, processor usage, processor usage fluctuation, system temperature, sensor-specific temperature, mobility, and acceleration. A method and a system also perform various functions of the apparatus.

  • Publication number: 20180317175
    Abstract: To secure the availability of a battery operation of a grouped plurality of mobile terminal devices. Grouped devices can communicate with a management server through a network. The management server stores state data received from the devices in a management table. The state data contains proximity information for judging the length of time until a user checks a screen and availability information associated with the availability of the battery operation. The management server selects a target device requiring a predetermined action and a notification device notifying a message associated with the predetermined action based on the state data from the plurality of devices. The management server notifies the notification device of a message associated with the predetermined action. The message can be a charging prompt or an approval for shutdown.

  • Patent number: 9967917
    Abstract: A mobile terminal device is connected to a network using a packet routing function of another mobile terminal device. Communication between respective mobile terminal devices can be performed in each of a plurality of tethering connection systems. When performing tethering communication, a mobile terminal device having tethering function becomes a master device and a mobile terminal device having no tethering function becomes a slave device. When both mobile terminal devices have tethering function, one mobile terminal devices becomes the master device and the other becomes the slave device. Before starting the tethering communication, state information for calculating an expected battery operating time of each mobile terminal device is acquired. A tethering connection system and a master-slave relationship are selected to maximize the expected operating time based on the remaining battery level and the expected power consumption of each mobile terminal device when starting the tethering communication.

  • Patent number: 9874912
    Abstract: An energization range of a laptop PC is controlled for safety component replacement. An EC can communicate with a battery unit to control a FET of the battery unit. In a power-off state, a PWC receives electricity from the battery unit or an AC/DC adapter. In the power-off state, a system of the EC stops. When a housing cover of the laptop PC is opened, a cover switch turns ON. When a logic circuit detects the operation of the cover switch, the PWC controls a DC/DC converter group to activate the system. The EC receiving electricity turns the FET OFF. Then the PWC turns the FET OFF.
