Thaum sib sau lub koos pis tawj cov koos pij tawj, ib qho teeb meem nquag tau txuas cov khawm loj: Lub zog thiab rov pib dua, nrog rau lub teeb taw qhia nyob ntawm sab xub ntiag. Txawm li cas los xij, txuas lub hwj chim khawm, tsis muaj lub computer yuav tsis qhib, yog qhov yooj yim heev. Nws tsis yog txawm tias yuav tsum muaj phau ntawv qhia siv rau qhov no.
Cov Lus Qhia

Tom qab kev teeb tsa lub motherboard sab hauv ntawm cov kab ke system thiab kho nrog nrog cov ntsia hlau ntsia hlau, nrhiav 2 kab ntawm tshwj xeeb me me pins rau nws. Feem ntau cov feem ntau lawv nyob rau ntawm sab ntawm lub rooj tsav xwm mus tib seem rau pem hauv ntej npog ntawm chav tsev. Cov pins no (tom ntej no peb yuav hu lawv tus pin-tiv tauj) tau kos npe nrog cov cim tsiaj ntawv sib txawv, piv txwv li, POWER_LED, HDD_LED, POW_ON, SPEAKER, thiab lwm yam.

Raws li, txhua ntawm cov pins no yog tsim los txuas cov diode cais lossis khawm. Qhov kev sib txuas yog tsim los siv cov xov hlau tshwj xeeb los ntawm cov khoom siv tau sib txuas hauv lub kaw lus. Yog li, dhau ntawm qhov interface no tau txuas nrog:
• Pib dua khawm;
• Lub zog khawm;
• Lub hwj chim teeb;
• Lub lag luam HDD teeb;
• Tus neeg hais lus ntawm chav system thiab qee yam khoom siv (kom paub meej, saib phau ntawv qhia txog cov neeg siv motherboard, uas tuaj yeem rub tawm ntawm lub khw tsim cov vev xaib).

Txhawm rau txuas lub hwj chim khawm rau lub motherboard, saib POW_ON tus yam ntxwv ntawm tus ncej. Xaiv ib qho cim uas muaj tib lub cim los ntawm cov xaim ntawm lub system. Saib xyuas cov polarity, txuas cov hlau nrog cov neeg tiv tauj. Txawm li cas los xij, polarity tuaj yeem pom ntawm Random. Thaum txuas nrog, nias lub pob kom Fais fab. Yog tias lub koos pis tawj tsis qhib, tig hla txoj xov txuas rau ntawm cov hlau.

Ib yam li ntawd, koj yuav tsum tsis txhob txuas lub pob nyem khawm nkaus xwb, tab sis kuj tseem muaj lwm tus neeg sib tiv tauj, piv txwv li, Qhov taw qhia lub Hwjchim. Qhov ntsuas HDD thauj khoom yog qee zaum tshwj xeeb tshaj yog siv - nws yog qhov zoo los ntawm nws thaum lub computer "khov". Txawm li cas los xij, koj kuj tuaj yeem ua tau yooj yim yog tias tsis muaj nws.
