Please refer to the first diagram and the second diagram, wherein the first diagram shows a portable computing device (hereinafter referred to as “portable computing device”) that operates at a high frequency in a mobile power mode provided by a preferred embodiment of the present invention. ) 1 is a block diagram; the second diagram is a three-dimensional schematic diagram showing a portable computing device 1 provided by a preferred embodiment of the present invention. A portable computing device 1 includes a power collection module 11, a built-in battery module 12 storing a built-in power, an embedded controller 13, a switching module 14, and a central processing unit (Central Processing Unit). (Hereinafter referred to as "CPU") 15 and a graphics processing unit (Graphics Processing Unit (hereinafter referred to as "GPU") 16). The power collection module 11 further includes a power collection unit 111 and a power distribution unit 112, and the switching module 14 further includes a switching unit 141 and a power supply reduction unit 142.

In this embodiment, the portable computing device 1 is a notebook computer provided with a computing device identification code, but is not limited thereto. The portable computing device 1 receives a mains power under a mains power supply mode and operates at a standard operating frequency, and receives a built-in power under a built-in battery power mode to save power at a frequency lower than the standard working frequency. Operating frequency operation. The standard operating frequency and the power-saving operating frequency are average values of the operating frequency of the CPU 15 and the operating frequency of the GPU 16. In the standard operating frequency, the operating frequency of the CPU 15 is the first CPU operating frequency, and the operating frequency of the GPU 16 is the first GPU operating frequency. In the power-saving operating frequency, the operating frequency of the CPU 15 is a second lower than the first CPU operating frequency. Two CPU operating frequencies, and GPU16 operating frequency is a second GPU operating frequency that is lower than the first GPU operating frequency.

When the portable computing device 1 is electrically connected to a mobile power device 2 provided with a power supply device identification code, the control module 22 of the mobile power device 2 judges that the computing device identification code is a boosted power supply code, and generates a Action control signals. The switching module 23 receives a motion control signal, The battery module 21 is switched on in a switched manner, and the mobile electrical energy stored in the battery module 21 is transmitted to the portable computing device 1. In this embodiment, the switching module 23 first transmits the mobile power to the boost circuit 24, and boosts the mobile power to a boost power through the boost circuit 24, and then transmits the boost power to the portable The expression computing device 1 is not limited thereto.

When the power collection unit 111 of the portable computing device 1 receives the boosted power and the embedded controller 13 determines to read the power supply device identification code, the portable computing device 1 will switch to A mobile operating frequency operates. Under the mobile operating frequency, the operating frequency of the CPU 15 is the first CPU operating frequency, and the operating frequency of the GPU 16 is a third GPU operating frequency. The third GPU operating frequency is intermediate between the first GPU operating frequency and the second GPU operating frequency, so that the mobile operating frequency is intermediate between the standard operating frequency and the power-saving operating frequency.

In this embodiment, the portable computing device 1 is electrically connected to the mobile power device 2 through a power line 3 and a transmission line 4, but it is not limited thereto. The portable computing device 1 receives mobile power through a power cord 3, but is not limited to this, and can also receive mobile power through a wireless power receiving method. In addition, the embedded controller 13 reads the power supply device identification code through the transmission line 4, but is not limited to this, and can also use wireless transmission, Bluetooth, Near-field communication (NFC), Radio frequency identification system (Radio Frequency Identification, RFID for short) and other reading methods.

After the portable computing device 1 is switched to operate at a mobile operating frequency, the embedded controller 13 will further determine the built-in power The remaining power of the built-in power is judged to be the existing technology, so it will not be repeated here. When the remaining power is higher than a synchronous power supply reference value, a control signal is generated, and the control signal is transmitted to the switching unit 141 in the switching module 14. When the switching unit 141 receives the above-mentioned control signal, it switches on the built-in battery module 12 to transmit the built-in power to the power supply amount reduction unit 142 also in the switching module 14. The switching unit 141 may be a switching switch, but is not limited thereto.

After receiving and reducing the built-in power, the power supply amount reduction unit 142 transmits the built-in power to the power collection unit 111. The power collection unit 111 combines the above-mentioned mobile power and the built-in power into a collective power, and The electric energy is transmitted to the electric energy distribution unit 112, so that the portable computing device 1 is upgraded to operate at a standard operating frequency under the mobile power supply mode. In the prior art, the problem that the portable computing device 1 cannot operate in a standard work mode in a non-mains power supply mode is solved. The power supply volume reduction unit 142 may be a variable resistor, but is not limited thereto, and may also be a metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET). In addition, the power supply amount reduction unit 142 may be a fixed type reduction or a variable type reduction. Fixed reduction is to reduce the built-in power to a fixed value, and the above fixed value is fixed; variable reduction is to reduce the built-in power to a reference value, but the above reference value can be It is operatively changed according to the user's setting requirements or according to the portable computing device 1.

The electric energy collecting unit 111 may be a bus bar, and the electric energy distributing unit 112 may be a power supply, but Not limited to this.

When the remaining power is not higher than the synchronous power supply reference value, the switching unit 141 will not turn on the built-in battery module 12, so that the portable computing device 1 operates at a mobile operating frequency under a mobile power supply mode, thereby making the portable The computing device 1 can take into account both the operating efficiency and the use time of the portable computing device 1 (the so-called extended power supply time of mobile power and built-in power).

In addition, when the portable computing device 1 is in a non-external power supply mode (mains power supply mode and mobile power supply mode), the embedded controller 13 generates a second control signal, and the switching unit 141 receives the second control signal. The ground conducts the built-in battery module 12 and the power collection unit 111 to directly transfer the built-in power of the built-in battery module 12 to the power collection unit 111 without passing through the power supply amount reduction unit 142. Therefore, after the power distribution unit 112 receives the above-mentioned built-in power, the portable computing device 1 switches to a power-saving operating frequency under the built-in battery power supply mode.

In the following, a practical example will be given for the embodiment of the portable computing device 1 provided by the present invention to make the present invention easier to understand.

Generally speaking, the medium-to-low-end notebook computers on the market require a total wattage of about 130 to 150 watts (for example, 140 watts) to operate at a standard operating frequency under the mains power supply mode. Mobile power devices generally provide wattages up to 100 watts (take 100 watts as an example). When a notebook computer is operating at a power-saving operating frequency under the built-in battery power mode, the total wattage provided by the built-in battery is about 60 to 80 watts (take 70 watts as an example).

After the notebook computer is electrically connected to the mobile power device, it will receive 100 watts of mobile power provided by the mobile power device and operate at the mobile operating frequency in the mobile power mode. The notebook computer will further determine whether the remaining power of the built-in battery is higher than the synchronous power supply reference value (ranging from 30% or 40%, which can be set according to the needs of the user). If the judgment result is yes, the built-in battery will be turned on , So that the built-in battery transmits 70 watts of built-in power. The total wattage required for a notebook computer to operate at a standard operating frequency is 140 watts, so the built-in power of 70 watts will be transmitted to the power supply reduction unit 142, and the 70 watt The built-in power is adjusted to 40 watts and transmitted to the power collection unit 111.

After the electric energy collecting unit 111 receives the above-mentioned built-in electric power of 40 watts, it integrates the built-in electric power of 40 watts and the mobile electric power of 100 watts into a collective electric power of 140 watts, and transmits the collective electric power of 140 watts to the electric energy distribution Unit 112. Therefore, the notebook computer will receive 140 watts of integrated power, so that the notebook computer can operate at the standard operating frequency in mobile power mode.

In addition, 30% of the power is used as the reference value for synchronous power supply and the boundary between high and low power. If the power of the notebook computer is higher than 30% and the power of the mobile power device is lower than 30%, according to the present invention, the notebook computer It is determined that the remaining power of the built-in battery is higher than the synchronous power reference value. Therefore, the notebook computer will operate at the standard operating frequency in the mobile power mode. The above situation is the notebook computer's self-judgment, which does not involve the user's artificial judgment. However, in practice, it will involve the user's artificial judgment. If one of the notebook computer and the mobile power device runs out of power, it will cause inconvenience to the user, so the above situation is in In practice, the user may first charge the mobile power device and switch the notebook computer to operate at a power-saving operating frequency under the built-in battery power mode. However, if the user finds that the power of the mobile power is less than 30% and takes no action, the notebook computer will still operate at the standard operating frequency in the mobile power mode.

Next, please refer to the first diagram and the third diagram together. The third diagram is a flowchart of a method for enabling the portable computing device to operate at high frequency in a mobile power mode provided by a preferred embodiment of the present invention. As shown in the figure, a preferred embodiment of the present invention provides a method for operating a portable computing device at a high frequency in a mobile power mode.

In this embodiment, the portable computing device 1 is electrically connected to the mobile power device 2 through a power line 3 and a transmission line 4, but it is not limited thereto.

Next, the embedded controller 13 further determines that the remaining power of the built-in power is higher than the synchronous power supply reference value, and then generates a control signal (ie, step S102). When the switching module 14 receives the control signal, the built-in battery module 12 and the power collection module 11 are switched on in a switched manner, so as to transmit the built-in power to the power collection module 11 (that is, step S103).

Finally, after receiving the built-in power, the power collection module 11 integrates the mobile power and the built-in power into the collected power, thereby The portable computing device 1 is upgraded to operate at a standard operating frequency in the mobile power supply mode (ie, step S104).

In summary, in the portable computing device operating at a high frequency under the mobile power supply mode provided in the present invention and the method for improving its operating frequency, the embedded controller is used to receive mobile power when the power collection module receives the mobile power. The identification code of the power supply device is read out. After further determining that the remaining power of one of the built-in electric energy is higher than a synchronous power supply reference value, a control signal is generated to enable the switching module to switch on the built-in battery module and the electric energy gathering module, and The power is transmitted to the power collection module.

The power collection module integrates the built-in power and mobile power into a collective power, so that the portable computing device can be switched to operate at a standard operating frequency in the mobile power mode, which solves the problem of non-commercial power supply in the prior art. Under the circumstances (including the built-in battery power supply mode and mobile power supply mode), it cannot effectively improve the operating performance of the CPU and GPU.
