Description
Technical field
The utility model relates to a kind of pair of video card notebook computer.
Background technology
The power problems of notebook computer is puzzlement deviser's a big problem always, it is related to the time length that battery uses, along with hardware constantly updates, more and more higher performance has produced increasing power consumption, and a vitals of power consumption is a video card and produce greatly, video card is divided into built-in and external, built-in video card generally is integrated in north bridge inside, and performance is general, and is low in energy consumption, power saving, but the display performance that obtains is low.The external video card is independent of north bridge, better performances, and by independently chip manufacturer's production, the display performance height of acquisition, but power consumption is big, takes.Experimental data shows: under notebook entered idle condition, the power consumption of the more built-in video card of external video card can increase 2-3w, and battery corresponding meeting in serviceable life is shortened 1-2 hour.External video card power consumption is bigger, but performance is very excellent, and the relatively power saving but performance is low of built-in video card makes that the deviser is difficult to accomplish to make the best of both worlds.
The utility model content
The purpose of this utility model provides a kind of north bridge chips that uses integrated built-in video card on the pcb board of notebook computer, the external video card of pegging graft simultaneously, computer is powered in running status or by external power supply, external video card is had an effect, the user can obtain higher display performance, when computer enters idle condition or when battery-powered, external video card is closed, the demonstration task is handed to built-in video card, different conditions in the computer operation makes internal or external video card play a role according to system requirements, reduce system power dissipation, reach power saving and prolong the battery purpose in serviceable life, carry out so by turns, make user's the notebook system power supply of reasonable use system more under the prerequisite of not losing high display performance, balance the contradiction of performance and power saving, optimized the notebook computer design, integrated external video card and built-in video card advantage separately realize two video card notebook computers of the power management of not only efficient but also power saving.
The purpose of this utility model can reach by following measure:
This pair of video card notebook computer, its special character is: the video card arbitration circuit connects corresponding display device through a group or more bus switch, connector, the video card arbitration circuit also is in series with the north bridge and the VGA connector of system load circuit for detecting, integrated built-in video card in parallel, and described VGA connector connects the north bridge of integrated built-in video card and pegs graft for external video card.
The purpose of this utility model can also reach by following measure:
Described bus switch is three, inserts CRT monitor through the CRT connector respectively, inserts LCD through the liquid crystal connector, inserts TV through the TV connector.
External video card is independent of outside the PCB mainboard.
The north bridge of integrated built-in video card is integrated on the PCB mainboard.
The north bridge of external video card and integrated built-in video card can co-exist on the PCB mainboard.
The utility model has the following advantages compared to existing technology:
1, makes notebook computer extending battery life 20%-30% under loss-free situation aspect the display performance.
2, bigger at external video card power consumption, but performance is very excellent, and built-in video card compares power saving but the low situation of performance, operation different conditions at computer makes internal or external video card play a role according to system requirements, when guarantee user's processing graphics, play games etc. requires high-performance to be met, can significantly reduce system power dissipation again, prolong battery serviceable life.
