Cov xwm txheej ntawm lub tshuab fais fab hauv lub computer, nws yog qhov taw qhia qhov twg voltages yuav tsum muaj nyob ntawm txhua qhov tawm. Feem ntau, txawm li cas los xij, cov kev hloov pauv no tsis raug rau cov npe nominal. Txhawm rau tshuaj xyuas yog tias qhov no yog, lawv yuav tsum tau ntsuas.
Cov Lus Qhia
Kauj ruam 1
Nrog lub khoos phis tawm ua haujlwm, koj tuaj yeem ntsuas tawm qhov tso tawm qhov hluav taws xob ntawm lub zog siv hluav taws xob siv cov khoom siv hluav taws xob analog-rau-digital hloov ua hauv motherboard. Rov qab pib lub tshuab thiab tam sim ntawd pib nias "Rho tawm" lossis "F2" qhov tseem ceeb (nyob ntawm tus qauv tswj hwm) ntau zaus kom txog thaum koj nkag mus rau CMOS Teeb kev pabcuam. Xaiv "PC Cov xwm txheej kev noj qab haus huv" los ntawm cov ntawv qhia zaub mov thiab koj yuav pom dab tsi voltages yog qhov tseeb ntawm qhov ua tau ntawm qhov muaj fais fab.

Ntau lub motherboard tsis qhia cov hluav taws xob standby fais fab mov voltage hauv CMOS Teeb. Ntsuas nws nrog multimeter ua haujlwm hauv DC voltage ntsuas ntsuas hom ntawm 20 volt txwv, txuas nws ntawm cov xaim dub thiab ntshav. Nco ntsoov tias nws tsis siab dhau los piv rau cov nqi nominal hauv ob qho tib si kev ua haujlwm thiab standby hom ntawm lub computer.

Yog tias lub koos pis tawj tsis ua haujlwm, tsis muaj "PC Health Status" ua haujlwm hauv CMOS Teeb, lossis yog koj tsis paub tseeb kev ua haujlwm ntawm ADC ntawm lub chaw nres tsheb, siv cov multimeter ua haujlwm nyob rau tib hom thiab ntawm tib qho kev ntsuas kom ntsuas txhua qhov ntsuas. Cov. Nqa tawm cov ntsuas nrog lub tshuab khiav, tu kom tsis txhob ua rau luv luv Circuit Court nrog cov khoom tawg.

Siv qhov tshwj xeeb sawv ntsug los kuaj xyuas cov voltages ntawm lub zog hluav taws xob hauv qab sib txawv load. Thauj khoom txhua qhov tawm nrog cov txuas tsheb sib txuas nrog lub tsheb teeb hauv qhov kom muaj nuj nqis uas noj tag nrho tam sim no me ntsis tsawg dua li cov npe tam sim no rau cov zis no. Nco ntsoov tias thaum lub sijhawm voltages ntawm 5 thiab 3.3 V, lub teeb tsa tsheb siv hluav taws xob tsawg: ntsuas ntsuas ua ntej nws yog dab tsi ntawm cov voltages ntawm ib lub teeb. Los ntawm txiav tawm qee lub teeb ntawm txhua qhov teeb meem, koj tuaj yeem simulate qhov txo qis hauv lub nra ntawm cov pa fais fab. Ua tiav kev ntsuas nyob rau hauv tib txoj kev raws li lwm yam mob.

Yog tias qhov no lossis qhov ntsuas hluav taws xob ntau dhau, siv tam sim ntawd siv lub tshuab fais fab thiab xa mus rau kev kho. Feem ntau yuav yog, cov hluav taws xob nce vim qhov ziab tawm ntawm lub tshuab hluav taws xob, tab sis tsuas yog tus tswv tsim nyog tuaj yeem hloov lawv tus kheej txawm nyob rau hauv kev hloov tawm ntawm cov khoom siv hluav taws xob siab, xws li lub tshuab hloov hluav taws xob.
