Daim npav POST qhia txog cov lej yuam kev tsim tawm thaum Lub Hwj Chim Ntawm Kev Ntsuas Tus Kheej. Nws yog siv los txheeb xyuas cov teeb meem uas tuaj yeem kuaj pom thaum lub khoos phis tawj pib, yog li nws yuav pab tau thaum koj lub khoos phis tawj yuav tsis qhib.
POST cov lej sib raug ncaj qha rau qhov kev sim uas ua tsis tiav thiab tuaj yeem pab txiav txim siab yam khoom kho vajtse ua teeb meem, txawm tias nws yog lub cim xeeb, hard drives, keyboard, thiab lwm yam.
Yog tias lub kaw lus tsis ntsib qhov yuam kev kom txog thaum tom qab thaum lub sijhawm khau raj tom qab daim npav video qhib, ces qhov yuam kev tuaj yeem tshwm sim ntawm qhov screen. Hom kev ua yuam kev no tsis zoo ib yam li POST code, tab sis hu ua POST yuam kev lus, uas yog cov lus uas tib neeg nyeem tau.
Yuav ua li cas POST Test Cards ua haujlwm
Feem ntau daim npav POST (aka, daim npav kuaj xyuas lossis chaw nres nkoj 80h phaib) ntsaws ncaj qha rau hauv qhov txuas hauv lub motherboard, thaum ob peb lwm tus txuas sab nraud los ntawm qhov chaw sib txuas lossis chaw nres nkoj. Daim npav POST sab hauv, tau kawg, xav kom koj qhib koj lub computer siv nws.
Thaum POST, tus lej ob tus lej xa tawm ntawm chaw nres nkoj 0x80. Qee daim npav suav nrog jumpers uas tso cai rau koj hloov kho qhov chaw nres nkoj los nyeem cov lej los ntawm, vim qee cov tuam txhab siv qhov chaw sib txawv.
Cov lej no yog tsim thaum txhua kauj ruam kuaj mob thaum lub sijhawm khau raj. Tom qab txhua daim ntawv kho vajtse raug txheeb xyuas tias ua haujlwm, cov khoom txuas ntxiv raug kuaj xyuas. Yog tias pom qhov yuam kev, cov txheej txheem khau raj feem ntau nres, thiab daim npav POST kuaj pom qhov yuam kev.
Koj yuav tsum paub BIOS chaw tsim khoom ntawm koj lub khoos phis tawj los txhais cov lej POST rau hauv cov lus yuam kev uas koj tuaj yeem nkag siab. Qee lub vev xaib, suav nrog BIOS Central, khaws cov npe ntawm BIOS cov neeg muag khoom thiab lawv cov lej POST yuam kev.
Piv txwv li, yog daim npav POST kuaj pom qhov yuam kev 28, thiab Dell yog BIOS chaw tsim khoom, nws txhais tau tias CMOS RAM roj teeb tau ploj mus. Hauv qhov no, hloov lub roj teeb feem ntau yuav kho qhov teeb meem.
Ntau Txog Daim Npav Xeem Xaib
Vim tias BIOS tuaj yeem xa cov lus yuam kev ua ntej daim npav video qhib, nws tuaj yeem ntsib teeb meem kho vajtse ua ntej lub monitor tuaj yeem tso cov lus. Qhov no yog thaum daim npav POST tuaj yeem ua ke-yog tias qhov yuam kev tsis tuaj yeem xa mus rau qhov screen, daim npav tseem tuaj yeem pab txheeb xyuas qhov teeb meem.
Lwm qhov laj thawj siv ib qho yog tias lub khoos phis tawj tsis muaj peev xwm ua suab kom muab qhov yuam kev, uas yog cov lej beep yog dab tsi. Lawv yog cov lis dej num uas muaj feem xyuam rau cov lus yuam kev tshwj xeeb. Thaum lawv muaj txiaj ntsig zoo thaum cov lus yuam kev tsis tuaj yeem tshwm sim ntawm qhov screen, lawv tsis muaj txiaj ntsig zoo ntawm cov khoos phis tawj uas tsis muaj tus neeg hais lus sab hauv, qhov twg tus lej POST tuaj yeem nyeem los ntawm POST xeem. daim npav.
Muaj tsawg tus neeg twb muaj ib tus neeg sim no, tab sis lawv tsis kim heev. Amazon muag ntau hom ntawv POST, ntau tus nqi qis dua $ 20 USD.
