Patent number: 6839853Abstract: To obtain a method for controlling power of a computer, a power control apparatus, and the computer which can prevent a user from feeling uneasy unnecessarily and inhibit a power-on problem from arising again. When the power switch is depressed, the power-on self test (POST) starts and if there is no error detected by that test in connection with the initialization of the IC, the operating system OS is loaded to make the computer operative (steps 200 through 208). If there is any error detected, a determination is made whether that error occurs as frequently as or more frequently than a predetermined number of times. If that error occurs as frequently as or more frequently than the predetermined number of times, an error indication is displayed and then the process ends. If that error occurs less frequently than the predetermined number of times, the error history is stored and then a setup for stabling the hardware operation is selected.Type: GrantFiled: January 12, 2001Date of Patent: January 4, 2005Assignee: International Business Machines CorporationInventors: Shigefumi Odaohhara, Arimasa Naitoh, Ken Inoue

Patent number: 6574740Abstract: Disclosed is a method and apparatus for controlling power consumption of the PC, which is provided with base loads comprising a plurality of components, as well as a CPU including operation modes of “throttling” and “clock-down”. Actual power consumption 103 of the CPU in a certain operation mode varies heavily or widely within a range of maximum power consumption of the CPU. A variation of actual power consumption 101 of the base loads is relatively gentle or mild. Predicted maximum power consumption (Pmax) of the PC is obtained from actual power consumption of the base loads and maximum power consumption in the current operation mode of the CPU. Reference power vales 121, 123, 125 are set up such that they are compared with the Pmax for changing an operation mode to another operation mode. When the Pmax exceeds a reference power vale, the operation mode of the CPU is changed for controlling actual power consumption of the PC.Type: GrantFiled: December 7, 1999Date of Patent: June 3, 2003Assignee: International Business Machines CorporationInventors: Shigefumi Odaohhara, Arimasa Naitoh

Patent number: 6388343Abstract: A leak current is prevented from flowing during a power off state in a power supply unit having a remote power on/off function by using the momentary switch. In a state of power off, i.e. a state in which a switch SW2 is turned off, power is not applied to a latch circuit 30, and hence power is not consumed. A switch drive circuit 40 does not consume power. When a user depresses a momentary switch SW1 during a state that the switch SW2 is turned off, the switch drive circuit 40 turns the switch SW2 on. As a result, the latch circuit 30 can receive a drive voltage VCC from a node located down stream of the switch SW2, so that it can store or latch the turn on state of the momentary switch SW1. After that, when the user releases the momentary switch SW1, it returns to an original position and operation of the switch drive circuit 40 which turns the switch SW2 on is terminated.Type: GrantFiled: February 25, 1998Date of Patent: May 14, 2002Assignee: International Business Machines CorporationInventors: Toru Michigami, Yukifumi Nakazawa, Arimasa Naitoh
