Abstract: Methods, apparatuses, and systems for managing power of a processing unit are described herein. Some embodiments include determining a voltage variation of a subset of current components of a current consumed by a processing unit. Other embodiments include detecting architectural events on a processing core of the processing unit and instituting various actions to reduce an input rate of instructions to the core. Other embodiments may be described and claimed.

Abstract: A display apparatus includes: a command receiver configured to receive power on or off command from an exterior, a power supply unit configured to supply power to the display apparatus and a control unit coupled to the command receiver and the power supply unit, determining whether auxiliary power exists when the power off command is received, wherein the control unit is configured for two power saving modes.

Abstract: According to one embodiment, an information processing apparatus includes a display unit, a touch panel, a BIOS storage unit, and a setup program execution unit. The display unit displays various kinds of information. The touch panel is installed on a display screen of the display unit and used for input corresponding to a contact operation. The BIOS storage unit stores a BIOS (basic input/output system) to execute startup of an operating system. The setup program execution unit executes a setup program for the BIOS in response to that an input from the touch panel is detected during the execution of the startup based on the BIOS.

Abstract: A power supply input circuit includes an input node configured to removeably couple to an electrical source. A solid state switch is coupled between the input node and a capacitive load. An RC soft start circuit is coupled to the input node and the switch. The soft start circuit has a capacitor that causes the switch to increasingly pass electrical power from the source to the load as the capacitor charges from the source. An active reset circuit is coupled to the soft start circuit. The reset circuit is configured to detect when the source is removed from the input node and in response to the source being removed from the input node, the reset circuit discharges the capacitor to reset the soft start circuit.
