The method comprises the steps of judging whether the desktop computer is in the suspend-to-memory mode, judging whether the system power of the desktop computer fails and then providing a backup power to the memory of the desktop computer when the desktop computer is in the suspend-to-memory mode and the system power of the desktop computer fails.

Abstract: A method for manufacturing glue-pasting area of field emission display forms a plurality of elongated low walls on glue-pasting area of the anode plate or the cathode plate by printing. The elongated low wall includes a length side parallel with a package side of the display. The elongated low walls are arranged on the glue-pasting area in staggered and parallel fashion, where a first gap is defined between two adjacent elongated low walls and the first gap is a channel for overflow glue after the cathode plate is pressed with the anode plate. After the glass glue is pasted on the elongated low wall and the cathode plate is pressed with the anode plate, the overflow glue is constrained b the gap to control the width of glue.

Abstract: A motherboard includes a north bridge circuit, a central processing unit (CPU) socket coupled to the north bridge circuit through a hypertransport bus; a first slot coupled to the north bridge circuit; and an upgrade slot, coupled to the second slot and the hypertransport bus, for installing a removable tunnel module. When the removable tunnel module is installed inside the upgrade slot, the motherboard is capable of supporting a computer component installed inside the second slot.

Abstract: A method for enhancing information security of a computer system for starting the computer system securely includes receiving radio frequency identification data when the computer system is switched on and controlling a power system of the computer system according to the radio frequency identification data.

Abstract: A motherboard includes a first CPU module including a first CPU slot and a first memory slot, a first north bridge circuit coupled to the first CPU module, a second CPU module including a second CPU slot and a second memory slot, a second north bridge circuit coupled to the second CPU module, a south bridge circuit coupled to the first north bridge circuit and the second north bridge circuit, and a selection circuit coupled to the south bridge circuit for coupling a north bridge circuit corresponding to a CPU slot containing a CPU to the south bridge circuit.

Abstract: An electronic device has a cavity in which a stylus can be slidably inserted. The stylus has a retaining slot thereon. Being inserted in the cavity, the stylus firstly pushes a retainer to be moved resiliently. The stylus further presses on a stylus-releasing device that terminates the cavity, thereby engaging the stylus-releasing device in a stable configuration with a resilient force. Meanwhile the retainer inserts into the retaining slot of the stylus to hold and immobilize the stylus in the cavity. To extract the stylus, a short pressing action is exerted on the stylus, which disengages the stylus-releasing device from the stable configuration, thereby the stylus-releasing device exerts a resilient force on the stylus that is ejected partially out of the cavity to facilitate a grasp of the stylus.

Abstract: A keystroke structure (3) for an electronic device which includes a shell (2) defining an opening (22). The keystroke structure comprises a cap (32) made of hard plastics such as ABS resin, a flange (34) fixed to a bottom of a periphery of the cap, wherein the flange is made of a material, such as rubber which is more elastic than that for forming the cap. The cap has a portion extending upward through the opening. A rod (42) extends downwardly from a bottom of the cap. A switch assembly (4) consisting of four first switches (44) for cursor direction control and a second switch (46) for “enter” control. The first switches are activated by the rod when the cap is titled, and the second switch is activated by the rod when the cap is vertically depressed. When the cap is titled to activate one of the first switches, the flange engage with a bottom face of the shell.

Abstract: To receive a stylus having a retaining slot thereon, the housing of an electronic device has a cavity in which the stylus can be slidably inserted. Being inserted in the cavity, the stylus contacts with a retainer that thereby resiliently deviates. The stylus further presses on a stylus-releasing device that terminates the cavity, thereby engaging the stylus-releasing device in a stable configuration in which resilient force is stored. Meanwhile the stylus engages the stylus-releasing device into the stable configuration, the retainer inserts into the retaining slot of the stylus to hold and immobilize the stylus in the cavity. To extract the stylus, a short pressing action is exerted on the stylus, which disengages the stylus-releasing device from the stable configuration, thereby the stylus-releasing device exerts a resilient force on the stylus that is ejected partially out of the cavity to facilitate a grasp of the stylus.

Abstract: A stylus for personal digital assistants including a stylus's body and a stabilizer is provided. The stylus's body is elliptically cylindrical with oval cross-section and has a central line, while the stabilizer is located inside the stylus's body but deviates from the central line. Among which, the stabilizer is located on the major axis of the oval cross-section shifting the position of the center of gravity of the stylus off the central line. Thus the stylus acquires more stability and will not roll around when placed on the desktop, providing handiness and convenience for the user to pick it up from the desktop.

Abstract: A mechanism for ejecting stylus includes the locking apparatus and the ejecting apparatus. When the stylus is put in the slide groove, the movable arm of the locking apparatus exactly hooks the rabbet of the stylus resulting in the retention of stylus. The ejecting apparatus is used for ejecting the stylus along the slide groove. The locking apparatus and the ejecting apparatus are set separately at the end of the slide groove, and the distance between two apparatus is exactly equal to the length of the stylus.
