Maitiro ekutarisa mamaboard ane multimeter

A motherboard ibhodhi rakadhindwa redunhu rine kana rinobatanidza zvese zvakakosha zvinodikanwa pakushanda kwekombuta kana mudziyo.

Iyi ndiyo inonyanya kukosha yedunhu mumudziyo wekombuta, kukundikana mairi kunotungamirira kukuti iyo yose mudziyo inomira kushanda kana haigoni kuita mabasa anokosha.

Sezvo uri pano, ndiri kufungidzira kuti wateura mvura pakombuta yako, uine ruzivo rwekuwedzera kwesimba kana kushanduka mumba mako, kana mamaboard ichangosakara uye uri kunetseka kuti inogona kusashanda zvakare.

Iwe uchazofanira kuongorora kana iri ndiro dambudziko riripo, sezvo kutsiva imwe yacho kunogona kudhura sekutenga komputa nyowani.

Mugwaro iri, iwe uchaona iyo yakazara maitiro ekutarisa iyo mamaboard ine multimeter.

Ngatitangei.

Zviratidzo zvebhodhi raamai rakashata

Zviratidzo zvakawanda zvinonongedza kune yakashata mamaboard, iine zvimwe zviri pachena uye zviri pachena kupfuura zvimwe. Zvimwe zvezvakawanda zvinosanganisirwa

• Kombiyuta haina kutanga
• Chishandiso hachiratidzi zviratidzo zvehupenyu kana chakabatana kune sosi yemagetsi,
• Kugara uchiwana skrini yebhuruu yerufu (ine meseji yekurodha yekukanganisa uye chiso chakasuruvara),
• Kombiyuta inotonhora kazhinji
• Kamwe kamwe uye kazhinji reboots ye processor,
• Kutadza kuziva zvimwe zvinhu zvehardware zvakaita se RAM,
• Komputa yako iri kupisa zvine njodzi,
• Kombiyuta inonzwika kana
• Kupisa kunhuhwirira kubva pabhodhi reamai. 

Kana iwe uri kusangana nechimwe cheizvi, inguva yekutarisa yako mamaboard kuti uone kana ichida kutsiviwa kana kwete.

Zvishandiso zvinodiwa pakuongorora bhodhi reamai

Kuti uedze mamaboard iwe uchada

• Multimeter
• Multimeter probes
• Screwdriver kuti uvhure komputa yako.

Multimeter ndiyo yakanakisa uye yakakosha chishandiso chekutarisa voltage uye kuramba kwebhodhi reamai, pamwe chete nezvimwe zvinhu zvemagetsi nemidziyo.

Maitiro ekutarisa mamaboard ane multimeter

Bvisa komputa yako, isa multimeter yako ku200 ohms, uye bvisa chinongedzo cheATX kubva pabhodhi reamai. Isa waya nhema pane chassis yesimbi yekombuta uye waya tsvuku pane imwe yemagetsi emagetsi e AC pasi. Iyo yakanaka mamaboard inopa zero ohms.

Kune mamwe maedzo ekupikisa aunogona kumhanya pabhodhi reamai kuti uone kuti iri muchimiro chakanaka.

Iwe unogona zvakare kuita DC voltage bvunzo pabhodhi reamai uye zvese zvinotsanangurwa zvakadzama.

Muedzo wekupokana wakanangana nekuona dunhu pfupi kana dunhu rakavhurika zvachose pabhodhi reamai kana mumagetsi ekubatanidza. 

1. Bvisa motherboard

Kuti uedze kupikisa mudunhu, haudi ikozvino kuyerera kuburikidza nayo.

Bvisa mudziyo wekombuta kubva kumagetsi sosi uye mirira maminetsi mashoma kusvika ikozvino mukati mebhodhi reamai yabviswa zvachose.

Mushure mekumirira anenge maminitsi gumi, enda kune nhanho inotevera. 

2. Seta multimeter kusvika 200 ohm renji

Resistance inoyerwa muohms, saka unotenderedza multimeter dial kuverenga ohms, iyo inomiririrwa neomega (Ω) chiratidzo.

Iyo 200 ohm renji ndiyo yakaderera renji iwe yauchawana pane multimeter uye zvakare ndiyo yakakodzera siyana kuti uwane yakanyatso mhedzisiro kubva pabvunzo yedu. 

Nekusagadzikana, iyo multimeter inoratidza "OL" kana yaiswa kuyera ohms.

Kuti utarise kana iyo multimeter inotungamira yakarongedzwa nemazvo, bata ma multimeter anotungamira kune mumwe nemumwe uye ona kana iyo multimeter ichiverenga zero (0) ohms.

Neimwe nzira, unogona kuisa waya mbiri pane simbi chassis yekombuta uye kuyedza kuverenga kwe zero kuramba.

Kana iwe ukawana kukosha uku, enderera kune nhanho inotevera. 

3. Bvisa iyo ATX yekubatanidza kubva pabhodhi reamai

Iyo ATX yekubatanidza ndicho chikamu chinopa simba kubhodhi reamai kuburikidza nePower Supply Unit (PSU). Iyo magetsi inoshandura AC voltage kuita yakaderera-simba DC voltage kuti ishandiswe nebhodhi reamai.

Kuti uvhure macontacts emagetsi, bvisa chinongedzo chemagetsi kubva pachiri. Iwewo uzviite nokungwarira kuti urege kukuvadza.

4. Isa maSensors paChassis uye ATX Pinouts

Muyedzo wekutanga wekupokana waunoita uri pachibatanidza. Iwe unoda kuyedza waya dzese dzinobatana kune magetsi uye kuona kuramba kwavo. 

Kutanga, isa waya nhema pane simbi yekombuta uye waya tsvuku pane imwe neimwe yemavara matema eGND waya pane chinongedzo.

Aya mawaya matema ari pasi anobatanidza uye anotarisirwa kupa multimeter kuverenga kwe zero ohms. Chero humwe hukoshi hunoratidza pfupi dunhu musimba rekubatanidza. 

Mushure mekutarisa waya dzeGND, unoenda kune waya dzine mavara.

Semuyedzo yapfuura, isa dema bvunzo inotungamira pane komputa uye isa iyo tsvuku bvunzo lead pane imwe neimwe yemavara waya.

Kune aya mawaya ane mavara, iwe ungatarisira kuramba kweinenge 50 ohms.

Kana iwe ukawana kuverenga pazasi 50 ohms pane chero waya, saka uyu ndiye ane mhosva uye simba rekubatanidza rinoda kutsiviwa. 

5. Kutarisa kushorwa pamaterminals emagetsi

Kana mawaya ese ekubatanidza akatariswa, unoenda kubhodhi remagetsi emagetsi slots.

Kuti uite bvunzo iyi nemazvo, iwe unozoda chaiyo ATX-20 pinout kune yako mamaboard. Mufananidzo uri pazasi unoratidza generic 20 uye 24 pini tafura inogona kukushandira iwe.

Pano tichave tichiyedza mapini ekubatanidza pasi akanyorwa kuti "COM" kuti tione kana vane chero nzira yekupikisa kana kwete. 

Isa iyo isina kunaka probe pachesi yesimbi yekombuta uye isa iyo dzvuku probe mune yega yega aya matema slots. Iwe unotarisira kuwana zero-resistance multimeter kuverenga kwepini yega yega.

Kana iwe ukawana chero kukosha kunze kwe zero, une chiratidzo chekuti panogona kunge paine pfupi mumagetsi ekupa.

Ichi chinogona kunge chiri chikonzero nei bhodhi reamai isiri kushanda, saka iwe unofanirwa kutsiva magetsi kana bhodhi rose. Colored slots inotarisirwa kuve nekupikisa kweinenge 50 ohms.

Kutarisa voltage pane motherboard

Imwe nzira yekuona kana bhodhi reamai rakashata ndeyekutarisa kana magetsi ekubatanidza ari kupa huwandu hwakakodzera hwemavolts.

Kuti uite izvi, tevera nhanho idzi.

1. Batanidza mudziyo kune sosi yemagetsi

Iwe unoda ikozvino inoyerera nemuchina chekombuta kuti uedze voltage pane yayo mamaboard zvikamu, saka unoipfekera mumagetsi sosi. Iwe zvakare unobatanidza iyo 20-pini yekubatanidza kune magetsi.

2. Seta multimeter kune 20V DC voltage renji

Kuti uwane mhinduro chaidzo, unoshandura dial ye multimeter pamusoro peiyo 20 VDC voltage renji. DC voltage inomiririrwa pane multimeter netsamba "V- (matatu-dot)" kana "DCV".

3. Rear sensor connection

Nekuti ma multimeter's anotungamira akakurisa kuti akwane mugomba chero ripi zvaro kuti ubatane nemagetsi ekubatanidza magetsi, unonzwa kubatana netsono nhete. 

4. Isa ma sensors pane rear sensor tsono

Zvino iwe teerera pano. Tichitarisa pamufananidzo wakapihwa kare, tinogona kuona kuti mapini eGND ari munzvimbo dzinotsvedza 3, 5, 7, 13, 15, 16 uye 17.

Iwe unoisa probe yako yakaipa pane tsono yeimwe yeiyi GND slots. Iwe unogona kushandura pakati peaya slots kuti uedze imwe neimwe.

Kuenderera mberi, unoisa probe yakatsvuka pane tsono dzema slots akanyorwa 8, 9, uye 14. Aya mabheti anoshanda pamagetsi akasiyana uye saka anopa mhinduro dzakasiyana. 

5. Kuongorora kwemhedzisiro

Papini 8 (PG kana Simba-OK) ungatarisira kuti magetsi ave pamusoro pe2.5V, inova huwandu hwevolts inoshandiswa nekombuta kutanga.

Kukosha uku kunotarisirwa kudonha kusvika zero (0) uye kukwira pamusoro pe2.5V zvakare kana iwe ukadzvanya bhatani reset. 

Nepini 9 (VSB) unotarisira kukosha pamusoro pe5 volts, uye nepini 14 (PS-ON) unotarisira kukosha pakati pe3 ne5 volts.

Kana iwe ukadzvanya switch yemagetsi, kukosha kubva pini 14 (PS-ON) inodonhawo kusvika zero (0).

Chero kumwe kuverenga pane multimeter kunoratidza kukanganisa kwesimba rekubatanidza kana magetsi ekupa kubata uye nekudaro inoda kutsiviwa. Izvi zvinogona kunge zviri chikonzero chekutadza kwebhodhi reamai. 

Paunenge uchiita bvunzo iyi, zvakakosha kuti utarise kumufananidzo uri pamusoro kuti uone macode emavara uye nekuisa kune imwe neimwe yekubatanidza.

mhedziso

Kutarisa bhodhi reamai ine multimeter inzira yakaoma, yakapihwa kuti chinongedzo chemagetsi uye magetsi ane mabheti ane chinangwa chakanyanya.

Nekudaro, kutevera gwara redu ndiyo nzira yakanakisa yekuona kuti chii chaizvo chakashata nekombuta yako pasina kusiya imba yako.

Inowanzobvunzwa Mibvunzo

Nzira yekuziva sei voltage pane motherboard?

Iwe unoseta iyo multimeter kune iyo 20VDC voltage renji, kumashure-kuongorora magetsi emagetsi, isa iyo nhema probe paGND pini, wobva waisa iyo dzvuku probe pane grey, girinhi, uye yepepuru yeruvara slots.

Ko bhodhi rakafa richabata moto here?

Kuti bhodhi reamai richavheneka zvinoenderana nechikamu chakakanganisika. Bhobhobhodhi yakafa zvachose hairatidze zviratidzo zvehupenyu, nepo, semuenzaniso, bhodhi reamai rine rakashata RAM slot rinogona kuramba richibata moto.
