Abstract:
A method for managing electric quantity of a battery is disclosed. The method includes charging a battery normally with a 4.2V voltage when a temperature of the battery is lower than a first threshold temperature; charging the battery continuously when the temperature of the battery is higher than the first threshold temperature and lower than a second threshold temperature and the electric quantity of the battery is lower than a first threshold voltage. On the contrary, the battery is not charged any more when the temperature of the battery is between the first threshold temperature and the second threshold temperature and the electric quantity of the battery is higher than the first threshold voltage or a first capacity. If the temperature of the battery is higher than a second threshold temperature, the battery is not charged any more regardless of the battery voltage.
Abstract:
A method for changing a booting source when a first operating system is being executed is disclosed. The method is utilized in a computer system having a first storage device storing the first operating system and a second storage device storing a second operating system. The method includes: receiving a signal from the second storage device; detecting whether the second storage device is a target device; setting the second storage device as a booting device; rebooting; and executing the second operating system from the second storage device.
Abstract:
A power control circuit and a power control method applied to a computer system are disclosed. A regulator receives a first voltage, the regulator converting the first voltage to an embedded controller voltage when the regulator is enabled. A detecting and controlling circuit receives the first voltage and the button signal, and the regulator is enabled when the detecting and controlling circuit detects the button signal. An embedded controller connects to the regulator for receiving the embedded controller voltage and outputting the plurality of power control signals. The embedded controller sends a power on signal to the detecting and controlling circuit to keep the regulator enabled.
Abstract:
A portable computer includes a host, a supporting frame, a displayer, two latches and a drive member. The supporting frame is pivotally connected with the host and having a straight sliding slot and a curved sliding slot. The displayer has two sliding members, which are pivotally connected with the supporting frame and slidably connected with the straight sliding slot and the curved sliding slot respectively. The displayer is operable to rotate relative to the supporting frame by either one of the two sliding members as a pivot. The two latches are slidably connected with the supporting frame. The drive member is slidably connected with the two latches and operable to control where either one of the two latches is located.
Abstract:
A foldable electronic device with an antenna including a first body, a second body, a pivotal mechanism, an antenna and a driving element is provided. The first body has a holding recess on one side thereof. The second body is located on the other side of the first body. The pivotal mechanism is used to pivotally connect the first body to the second body. Two sides of the driving element are connected to the pivotal mechanism and the antenna, respectively. When the first body is opened relatively to the second body, the pivotal mechanism drives the driving element to generate a first linear displacement. The first linear displacement drives the antenna to have a second rotation displacement to allow the antenna to extend out of the receiving groove.
Abstract:
A computer system and overclock controlling method and program thereof, which includes steps of providing an overclock work voltage to a CPU when overclock is requested, then the CPU adjusts its clock domain according to the overclock work voltage. The overclock work voltage is a sum of a normal work voltage and an additional external voltage, by which the CPU may enter an overclock mode (a frequency of a clock domain signal is higher than a standard frequency value). Eventually, when the frequency of the clock domain signal of the CPU is in a stable status during the overclock mode, the work voltage for the CPU is reduced and the CPU keeps working in the overclock mode.
Abstract:
A display module includes a display panel and a reaction device. The reaction device includes a feedback unit array and a control unit. The feedback unit array has multiple feedback units to be arranged on the display panel in an array to divide the display area into multiple sub display areas, and each sub display area corresponds to one of the feedback units, respectively. When one of the sub display areas is touched, the control unit outputs a control signal to the feedback unit array, and the feedback unit corresponding to the touched sub display area generate a microcurrent.
Abstract:
The invention discloses a circuit board. The circuit board includes a body having an electric component holding portion according to the invention. A plurality of groups of fixing holes for fixing various types of heat dissipating devices are formed on the body adjacent to the electric component holding portion. With such a systematized layout, as a result, the number of fixing holes arranged is increased to improve the compatibility of circuit board for various heat dissipating devices, in spite of a limited space allowed on the circuit board.
Abstract:
A method for determining a disk type is provided. In the invention, a pickup head of a DVD optical drive is moved to a blank area of the disk where no data is stored. After rotation of the disk is stopped, the blank area is irradiated with a laser beam, and reflective signals reflected from a surface layer and a reflective layer of the disk are measured respectively. According to a time difference between the two reflective signals, the type of the disk placed in the DVD optical drive is determined. Therefore misjudgment because of effects of pits in a data area of the disk on the reflective signals can be avoided, so that the disk type can be accurately determined.
Abstract:
A motherboard which can play an image or a video in a power-off state is disclosed. The motherboard includes a circuit board, a north bridge chipset, a digital photo frame chipset, and a switch unit. The north bridge chipset, the digital photo frame chipset, and the switch unit are disposed on the circuit board. The digital photo frame chipset is activated according to a stand-by power in the power-off state. The switch unit is electrically connected with the north bridge chipset and the digital photo frame chipset, respectively. The switch unit electrically communicates with the north bridge chipset or the digital photo frame chipset according to a triggering signal. The motherboard may utilize the stand-by power in the power-off state to display an image by a display device via the digital photo frame chipset and the north bridge chipset when a computer system is powered off.
