Rov kho cov niam tsev yog qhov nyuaj txaus. Nws yog ib qho tsim nyog yuav tsum tsis yog tsuas yog rhuav tshem lub computer thiab tshem tawm cov microcircuit no, tab sis tseem yuav tsum ntsuam xyuas nws, kom thiaj li nrhiav tau cov ua yuam kev thiab hloov lawv. Yog li ntawd, nws yog qhov zoo dua los kawm kho cov laug cam ntawm cov qauv qub thiab tsis tsim nyog.
Tsim nyog
- - soldering chaw nres tsheb nrog processor tswj;
- - txheej teeb tsa cov ntsia hlau, tuav pov hwm, clamps;
- - khoom seem tshiab;
- - multimeter.
Cov Lus Qhia

Feem ntau cov feem ntau, cov txuas sab qab teb los yog sab qaum teb hlawv tawm ntawm lub microcircuit - ib txoj xov ntawm lub hwj chim tsaj hluav taws xob uas muab hluav taws xob rau cov niam tsev. Nws yog qhov yooj yim yooj yim los txiav txim siab qhov kev tawg zoo no - thaum khoos phis tawj, lub rooj tswj hwm nws tus kheej sai dhau. Cov cua kub dhau no tuaj yeem hnov koj tus ntiv tes yog tias IC loj heev thaum kub siab. Cov choj tsis zoo muaj muag thiab hloov nrog cov tshiab uas muaj cov npe zoo sib xws. Thov nco ntsoov tias qee zaum muaj qhov yuam kev North Bridge FET tuaj yeem yog qhov ua rau muaj kev kub ntxhov hauv cov choj. Yog tias koj xav tias qhov ua tsis zoo ntawm ib qho ntawm tus choj, ntsuas lawv qhov kev tawm tsam ntawm USB cov cim "Cov Ntaub Ntawv +" thiab "Cov Ntaub Ntawv-". Tus ua haujlwm stabilizer yuav tsum muaj qhov nruab nrab txog ntawm 600 ohms.

Motherboard roj teeb tsis ua haujlwm yog tsis muaj ntau. Yog tias CMOS Cov Roj Teeb Muaj Teeb Meem tshwm thaum pib lub computer, pib rov qab los ntawm kev hloov lub roj teeb no. Txhawm rau ua qhov no, ntawm daim ntawv thaiv ntawm motherboard, khoov rau cov hlau khawm tuav lub roj teeb rov qab thiab nws yuav hlav tawm. Yuav cov khoom tshiab los ntawm lub khw hauv computer thiab nruab nws hauv lub qhov (socket). Nco ntsoov txheeb xyuas qhov BIOS Teeb tsa tom qab hloov lub roj teeb.

Hloov cov roj txias yog qhov mob siab thiab mob siab rau lub zog. Yuav luag txhua lub khoos phis tawj niaj hnub no, lub txias txias yog ib puag ncig ntawm cov lej loj ntawm cov twj siv hluav taws xob thiab nruab nrog lub nruj uas tiv thaiv nws los ntawm hloov chaw. Yog tias koj txhob txwm xoob lossis ua kom puas tsawg kawg ib qho ntawm lub nce, sai lossis tom qab lub processor yuav poob. Txhawm rau txiav cov txuas, ntxig lub hau ntswj ntawm nruab nrab cov ntaub ntawv txias dua thiab niam daim ntawv thiab nias maj mam muab. Ua tib zoo qhib txhua tus txuas thiab tshem tawm cov faulty txias.
Kauj ruam 4
Ua tib zoo saib cov twj siv hluav taws xob ntawm daim txiag. Lub qhov tsis xws luag yog raug kuaj pom los ntawm o, ua txhaum kev ncaj ncees, tev ntawm qab roj hmab gasket. Ib txoj hauv kev tseeb dua los nrhiav lub capacitor tawg yog kuaj nws lub peev xwm nrog multimeter. Raws li txoj cai, motherboard muaj ntau lub kaum capacitors, yog li nws nyuaj rau nrhiav ib tug faulty.
Kauj ruam 5
Txhawm rau kom rov ua cov microcircuit thiab cov khoom siv, tsuas yog siv cov chaw tsim hluav taws xob tswj chaw nres tsheb. Siv tsis tau cov ntsej muag tes tuav taw uas tsis tuaj yeem siv, vim tias lawv tsis tuaj yeem muab cov cua sov ua kom zoo ibyam thiab tshem tawm cov kav hlau. Ua tib zoo yaj cov lub capacitor puas thiab solder qhov tshiab hauv nws qhov chaw, nruj saib xyuas nws cov polarity. Tsis ua kom pom qhov polarity ntawm lub capacitor yuav ua rau nws tawg tam sim ntawd thaum thawj zaug sim tig rau ntawm lub rooj tsav xwm.
