Description
Technical field
The present invention relates to the connection and control of a kind of notebook computer, more particularly to its battery, in International Patent Classification (IPC)
In, G06F1/26 can be belonged to.
Background technology
For notebook computer, its battery for being not connected in the case of external power source as complete machine internal electric source exists always
Life problems, industry is always to improve its life-span and effort, but the design of prior art is all relatively complicated and effect is not still good enough.
The content of the invention
The technical problems to be solved by the invention are to propose a kind of notebook computer, and its battery life can be made significantly to prolong
It is long, for this is improved relatively simple for structure and cost is relatively low and energy-conservation.
The technical scheme that the present invention solves technical problem is, straight outside a kind of notebook computer, including motherboard, battery and machine
Flow power interface；Motherboard has power input, it is characterised in that：Also include the 1st switch and the 2nd switch, the battery warp
1st switch is access to DC source socket, and the power input of motherboard is access to battery through the 2nd switch；1st switch and the 2nd
Switch has following working method：
--- when computer receives power initiation instruction, the 1st switch connection, the 2nd switch connection；
--- when computer receives power supply halt instruction, the 1st switch then turns off, and motherboard starts to reset, and the 2nd
Switch disconnects after the completion of main frame sheet reset.
Research shows that battery is chronically at the main reason for fully charged state is shorter battery life.The technical program
Ingenious to be, after computer receives power supply halt instruction, the switch 1 then turns off, thus the outer dc source of cutting machine；It is main
Machine plate by battery powered and starting to reset, the battery of former full charge be consumed in motherboard reseting procedure electricity thus it is gradual
Depart from fully charged state, switch 2 disconnects after the completion of main frame sheet reset, battery is disconnected with motherboard.Detection shows, now electric
Still possess very high charge volume in pond --- substantially the 99.5% of full charge amount, but reliably enough departed from physical significance
Fully charged state, so that battery will not be chronically at fully charged state after computer stopping, greatly prolonging the life-span of battery,
Make battery that there is higher charge volume compared with prior art simultaneously.Obviously, the technical scheme uses fairly simple circuit and control
System, makes battery reliably depart from fully charged state when not in use, and battery is departed from the electric discharge of fully charged state and be used for main frame
Sheet reset process operation saves electric energy without wasting.
Brief description of the drawings
Fig. 1 is notebook computer circuitry schematic diagram of the embodiment of the present invention.
Fig. 2 is the circuit diagram of the further specific design of notebook computer of the embodiment of the present invention.
Embodiment
Notebook computer circuitry of the embodiment of the present invention is as shown in figure 1, including motherboard 3, power initiation/halt instruction device
4th, the battery GB and outer DC source socket DC of machine；Motherboard has power input VDD, in addition to the 1st electronic switch 1 and the 2nd
Electronic switch 2, controlled loop 1a -1bs of the battery GB through the 1st electronic switch 1 are access to DC source socket DC, the electricity of motherboard 3
Source controlled loop 2a -2bs of the input VDD through the 2nd electronic switch 2 is access to battery GB；In the I/O port of CPU in motherboard 3,
The control signal 1c of the electronic switch 1 of IO1 connections the 1st, the control signal 2c of the electronic switch 1 of IO2 connections the 2nd, IO3 connections electricity
The output signal end of source startup/halt instruction device 4, above-mentioned all circuits are respectively provided with publicly GND, in the CPU in motherboard 3
Programme-control IO1, IO2 and IO3 are put, makes computer that there is following working method：
--- when IO3 receives the power initiation instruction of the output of power initiation/halt instruction device 4, IO1 is to the 1st
The control signal 1c output signals of electronic switch 1, its controlled loop 1a -1b are connected, controls of the IO2 to the 2nd electronic switch 2
Input 2c output signals, its controlled loop 2a -2b are connected, and battery GB, DC source socket DC and motherboard 3 power supply are defeated
Enter to hold VDD to connect, power input VDD of the external dc power from DC source socket DC through motherboard 3 is to motherboard
Battery GB is charged while power supply；
--- when IO3 receives the power supply halt instruction of the output of power initiation/halt instruction device 4, motherboard 3 enters
Enter reseting procedure, IO1 stops the control signal 1c output signals to the 1st electronic switch 1, and its controlled loop 1a -1b breaks immediately
Open, controlled loop 2a -2b of the 2nd electronic switch 2 is still switched on, and the external dc power from DC source socket DC stops
Power input VDD through motherboard 3 powers to motherboard, and changes and powered by battery GB；Motherboard 3, which resets, to be finished, and IO2 stops
To the control signal 2c output signals of the 2nd electronic switch 2, its controlled loop 2a -2b disconnects, electricity of the battery GB through motherboard 3
Source input VDD powers to motherboard to be stopped.Computer is stopped.
The circuit of the further specific design of notebook computer of the embodiment of the present invention is as shown in Fig. 2 through photoelectric isolating device K1a
The triode V1a and its sustained diode 1a of control play the control action of the 1st electronic switch 1 in Fig. 1, through photoelectric isolating device
The triode V2a and its sustained diode 2a of K2a controls play the 2nd electronic switch 2 in Fig. 1, and button SB plays electricity in Fig. 1
The effect of source startup/halt instruction device 4, the course of work are as follows：
--- it is stopped but DC source socket DC has connected the computer of external dc power first after button press SB,
IO3 obtains the voltage from battery GB, and IO1 is to photoelectric isolating device K1a output signals, triode V1a conductings, and IO2 is to photoelectricity
Isolating device K2a output signals, triode V2a conductings, battery GB, DC source socket DC and motherboard 3 power input
VDD is connected, and power input VDD of the external dc power from DC source socket DC through motherboard 3 powers to motherboard
While battery GB is charged；
--- the computer button SB that in running order and DC source socket DC has connected external dc power is pressed
Afterwards, motherboard 3 enters reseting procedure, and IO3 loses the voltage from battery GB, and IO1, which stops exporting to photoelectric isolating device K1a, to be believed
Number, triode V1a cut-offs, the external dc power from DC source socket DC stops the power input VDD through motherboard 3
Powered to motherboard, and change and powered by battery GB；Motherboard 3, which resets, to be finished, and IO2, which stops exporting to photoelectric isolating device K2a, to be believed
Number, triode V2a cut-offs, power input VDDs of the battery GB through motherboard 3 powers to motherboard to be stopped, and computer is stopped.
The circuit of the further specific design of notebook computer of the embodiment of the present invention can also have using the other of prior art
