Abstract: A power management method is disclosed. The power management method comprises the step of a computer system checking existence of a manufacturing identifier (ID) of a human interface device (HID) when the computer system is operated in a first mode; the computer system continuously detecting whether the HID exist when the manufacturing ID exists; the computer system starting a timer when the computer system detects that the HID does not exist; the computer system entering a second mode when the timer expires; the HID determining whether the computer system is operated in the second mode, when plugged into the computer system; the HID performing state transition on the computer system when determining that the computer system is in the second mode; and the computer system entering the first mode when detecting the state transition.

Abstract: A read apparatus provided by the present invention has a screen, a storage unit and a processing module. The storage unit saves at least one e-book having a plurality of pages. Wherein, the processing module is coupled to the screen and storage unit. Therefore, the processing module can display the e-book on the screen, so as to responde a read request. Meanwhile, when the word size of the e-book has been adjusted, the processing module maintains original contents corresponding to each of pages in e-book for responding a browse request.

Abstract: An e-book read apparatus has a screen, a storage unit, a processing module and a layout tool. The storage saves at least one e-book having a plurality of chapters and sections, and pages. The processing is coupled to the storage unit for showing the e-book on the screen for responsing a read request. In addition, the layout is installed in the processing module or the storage unit for re-typeset the e-book for responsing a re-layout request.

Abstract: An operation method for an e-book is provided that links to an index database of the e-book, wherein the index database has a plurality of index objects and a plurality of index information corresponding to each of index objects. In addition, the index formation shows page numbers of a plurality of pages having the index objects in the e-book. Then, a plurality of briefs of the pages recorded in each of index information are obtained, and added in to corresponding index information for rebuilding index database. When one of index objects is selected on an index screen, the updated index information of the selected index object is showed on the index screen by the present invention.

Abstract: An AIO PC has its LVDS link or interface, between the mother board and the LCD, modified by the insertion of an LVDS Switch which can connect to a second LVDS source such as LCD controller which takes its input from a socket mounted on the housing of the AIO PC. The LVDS switch and LCD controller are located within the enclosure or housing of the AIO PC. The LVDS switch is controlled by a physical electromechanical switch.

Abstract: An electrical connector includes an insulating body, a plurality of first terminals, a plurality of second terminals and a shielding shell. A base on the insulating body includes a first solder portion, a second solder portion and a connection portion. The first solder portion and the second solder portion are located on the one end of the base, and the connection portion is located on the other end of the base. The first terminals run through the base, and are arranged parallel to each other and located on two sides of the first soldering portion and the connection portion. The second terminals run through the base, and are separately located on two sides of the second soldering portion and the connection portion. At least two of the second terminals are bent outwardly at a predetermined angle, so that the cross talk between two adjacent second terminals can be reduced. The shielding shell sleeves on the connection portion.
