Accompanying drawing explanation
Fig. 1 is a kind of notebook memory slot quick diagnosis card partial circuit diagram that the present invention proposes;
Fig. 2 is a kind of notebook memory slot quick diagnosis card partial circuit diagram that the present invention proposes.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of notebook memory slot quick diagnosis card that the present invention proposes comprises memory bar analog card, multiple LED, power supply and switch.
Memory bar analog card is SO-DIMM-204P encapsulation mode, and it comprises 108 signal ends, is respectively: DQ address location DQ0, DQ1-DQ63 be totally 64 signal ends; DQS address location DQS N0, DQS N1-DQSN7, DQS P0, DQS P1-DQS P7 be totally 16 signal ends; Addr address location A0, A1-A15 be totally 16 signal ends; DM address location DM0, DM1-DM7 be totally 8 signal ends; Clock unit CK P0, CK P1, CK N0, CK N1 be totally 4 signal ends.
The quantity of LED is 108, and 108 signal ends of LED and memory bar analog card connect one to one.The negative pole of each LED is connected to the signal end of memory bar analog card respectively, and the positive pole of each LED is all connected to switch first end, negative pole connecting valve second end of power supply.The positive pole of power supply is connected to earth terminal, and the common port of memory bar analog card is connected to earth terminal.
The diagnostic card that present embodiment provides adopts the golden finger encapsulation mode consistent with memory bar, to insert in memory slot.
The diagnostic card that present embodiment provides in working order under, diagnostic card is inserted in memory slot by golden finger, turn on-switch, and memory bar analog card, LED and power supply form loop; Each signal end of memory bar analog card is loaded into the impedance of memory slot each road internal memory signal and correspondence, thus LED corresponding to signal end forms normal path and light; When signal end disconnects or impedance is abnormal, the LED that signal end is corresponding can not form normal path, and turn on-switch LED is also the state of going out, then represent that memory slot is to should the signal wire of LED break down.
In present embodiment, by internal memory analog card, LED indicates each road signal condition corresponding in memory slot respectively, can by the light and shade state of LED each on inspections and examinations card, in quick diagnosis mainboard, CPU is to the break-make of memory slot signal wire, judge memory slot signal whether have problem and quick position to problematic signal wire, substantially increase efficiency and the accuracy of mainboard maintenance, thus saving maintenance cost.
