Patent number: 9639075Abstract: A status controller, a computer system, and a status detecting method thereof are disclosed. The status controller is used in the computer system. A main controller is used for indicating a shutdown status or an active status by a first level of an active-shutdown indicating interface pin. The status controller includes a hardware basic input output controller and an embedded controller. The hardware basic input output controller is used for indicating whether the computer system is in a sleep status by a second level of a system controlling interface pin, wherein when the computer system is in the sleep status, the hardware basic input output controller changes the second level. The embedded controller determines whether the computer system is in the shutdown or the active status by the first level and in the sleep status by the second level.Type: GrantFiled: January 15, 2014Date of Patent: May 2, 2017Assignee: Wistron CorporationInventors: Chao-Hsiang Chung, Yuan-Chan Lee

Publication number: 20130080755Abstract: A method for speeding up the boot time of an electric device and the electric device are disclosed. The disclosed method includes measuring power consumption of the electric device and determining whether the power consumption is greater than a threshold level, wherein the measuring and the determining steps are executed during a boot process of the electric device. If the power consumption is greater than the threshold level, a connector port controller initialization procedure is performed during the boot process, to initialize the connector port controller accordingly. If the power consumption is not greater than the threshold level, a simplified form of the connector port controller initialization procedure is performed during the boot process, to speed up the boot time.Type: ApplicationFiled: December 29, 2011Publication date: March 28, 2013Applicant: WISTRON CORP.Inventors: Wen-Tai Lin, Yu-Jyun Tang, Yuan-Chan Lee
