Apple Hardware Test (AHT) yog daim ntawv thov dav uas tuaj yeem pab kuaj xyuas cov teeb meem ntsig txog kho vajtse koj yuav ntsib nrog Mac laus dua. AHT tuaj yeem kuaj xyuas cov teeb meem nrog Mac's zaub, duab, processor, nco, logic board, sensors, thiab cia.
Cov ntaub ntawv hauv kab lus no siv rau Macs tsim xyoo 2012 thiab ua ntej.
Cas of Mac Hardware Failures
Qee Mac teeb meem, xws li cov teeb meem pib, tuaj yeem tshwm sim los ntawm software lossis teeb meem kho vajtse. Ib qho piv txwv zoo tau daig ntawm lub vijtsam xiav lossis grey screen thaum koj pib Mac. Yog vim li cas lub Mac yog daig yuav yog ib tug hardware los yog software teeb meem. Khiav Apple Hardware Test tuaj yeem nqaim qhov laj thawj.
Apple kho vajtse tsis ua haujlwm ib ntus, nrog qhov tsis ua haujlwm feem ntau yog RAM. Rau feem ntau Macs, RAM yog ib qho yooj yim los hloov, thiab khiav Apple Hardware Test kom paub meej tias RAM tsis ua haujlwm yog ib txoj haujlwm yooj yim.
Apple Hardware Test Availability
Tsis yog txhua Macs khiav AHT. Ntawm cov uas ua, txoj kev sib txawv nyob ntawm seb lub operating system version ntsia ntawm lub Mac.
- Macs tsim tawm xyoo 2012 thiab ua ntej nrog OS X Mountain Lion (10.8.4) lossis tom qab tau teeb tsa muaj Apple Hardware Test ua rau hauv Mac.
- Macs ua rau xyoo 2012 thiab ua ntej nrog OS X Mountain Lion (10.8.3) lossis ua ntej txhim kho siv lub system software disc lossis flash drive uas tuaj nrog Mac.
- Macs tsim tawm xyoo 2013 thiab tom qab ntawd tsis sib xws nrog AHT.
Rau txhua xyoo 2013 thiab tshiab dua Macs, Apple tau hloov kho kho vajtse sim siv Apple Diagnostics, uas yog tsim rau hauv Mac.
AHT ntawm Macs uas xa nrog OS X Lion lossis Tom qab
OS X Lion tau tso tawm thaum lub caij ntuj sov xyoo 2011. Lion tau cim qhov kev hloov pauv los ntawm kev faib OS software ntawm lub cev tawm (DVDs) los muab cov software ua ib qho rub tawm. Ua ntej OS X Lion, Apple Hardware Test tau muab rau ntawm ib qho ntawm cov teeb tsa DVDs uas tau suav nrog Mac. Nws kuj tseem suav nrog USB flash drive rau lub sijhawm ntxov ntawm MacBook Cua, uas tsis muaj qhov kho qhov muag tawm.
Nrog OS X Lion thiab tom qab ntawd, rau ib qho Mac tsim ua ntej 2013, AHT suav nrog hauv qhov muab faib zais rau ntawm Mac pib tsav. Yog hais tias lub Mac muaj tsov ntxhuav los yog tom qab ntsia, koj nyob nraum teem rau khiav lub Apple Hardware Test.
AHT ntawm Macs uas xa nrog OS X Leopard rau OS X Snow Leopard
OS X Leopard (10.5) tau tso tawm thaum lub Cuaj Hlis 2008. Rau Macs uas tau muag nrog OS X 10.5.5 thiab tom qab versions ntawm Leopard lossis nrog ib qho version ntawm OS X Snow Leopard (10.6), AHT nyob. ntawm Daim Ntawv Thov Nruab Disc 2 DVD nrog rau Mac.
MacBook Air cov tswv uas yuav lawv Macs lub sijhawm no tuaj yeem nrhiav AHT ntawm MacBook Air Reinstall Drive. Nws yog USB flash drive nrog rau kev yuav khoom.
kab hauv qab
Yog tias koj yuav Intel-based Mac hauv lossis ua ntej lub caij ntuj sov xyoo 2008, AHT pom ntawm Mac OS X Nruab Disc 1 DVD suav nrog kev yuav khoom.
AHT ntawm PowerPC-Based Macs
Rau Macs qub, xws li iBooks, Fais Fab Macs, thiab PowerBooks, AHT yog nyob rau ntawm ib qho CD cais nrog rau Mac.
Yuav ua li cas khiav Apple Hardware Test
Tam sim no koj paub qhov twg AHT nyob, koj tuaj yeem pib Apple Hardware Test.
- Ntxig qhov tsim nyog DVD lossis USB flash drive nrog AHT ntawm nws rau hauv Mac. Cov kauj ruam no tsis tsim nyog rau Macs nrog tsov ntxhuav lossis tom qab ntawd, qhov twg AHT nyob rau ntawm kev faib tawm ntawm lub hard drive.
- Kaw lub Mac.
- Yog tias koj tab tom sim Mac portable, txuas rau AC lub zog. Tsis txhob khiav qhov kev sim los ntawm Mac lub roj teeb.
- Nias lub power khawm pib lub Mac thiab tam sim ntawd nias thiab tuav tus yuam sij D. Txuas ntxiv tuav tus yuam sij D kom txog thaum koj pom lub cim me me ntawm Mac ntawm cov zaub. Thaum koj pom lub cim, tso qhov D tus yuam sij.
- Xaiv hom lus los ntawm cov npe ntawm cov lus uas tuaj yeem siv los khiav AHT, tom qab ntawd nyem rau sab xis-ntsej muag hauv qab. Lub Apple Hardware Test kuaj xyuas seb cov khoom siv twg tau teeb tsa hauv Mac. Tos kom lub hardware soj ntsuam kom tiav. Thaum nws tiav lawm, lub pob Test yog tseem ceeb.
-
Saib seb kho vajtse qhov kev sim pom los ntawm nyem Hardware Profile. Saib los ntawm cov npe ntawm cov khoom kom ntseeg tau tias Mac cov khoom tseem ceeb tshwm sim kom raug. Yog hais tias cov ntaub ntawv configuration zoo nkaus li yog lawm, xaiv Test.
Yog tias muaj qee yam zoo li tsis raug, txheeb xyuas Mac qhov teeb tsa los ntawm kev txheeb xyuas Apple qhov chaw txhawb nqa rau cov lus qhia tshwj xeeb ntawm Mac. Yog tias cov ntaub ntawv kev teeb tsa tsis sib xws, lub cuab yeej yuav ua tsis tiav thiab yuav tsum tau kho lossis hloov pauv.
- Click Hardware Test. AHT txhawb nqa ob hom kev xeem: kev xeem tus qauv thiab kev xeem txuas ntxiv. Qhov kev sim txuas ntxiv pom muaj teeb meem nrog RAM lossis duab. Yog tias koj xav tias muaj teeb meem zoo li no, pib nrog qhov luv dua, ntsuas tus qauv.
- Click Test. AHT qhia cov xwm txheej bar thiab cov lus yuam kev uas yuav tshwm sim los ntawm kev sim. Qhov kev xeem tuaj yeem siv sijhawm ntev. Koj tuaj yeem hnov txog Mac cov kiv cua rov nce thiab nqis. Qhov kev ua kiv cua no yog qhov qub thaum lub sijhawm sim.
- Thaum qhov kev xeem tiav lawm, qhov xwm txheej bar ploj mus, thiab qhov ntsuas qhov ntsuas thaj tsam ntawm lub qhov rais nthuav tawm cov lus Tsis Muaj Teeb Meem Pom lossis cov npe teeb meem. Yog tias koj pom cov lej yuam kev hauv cov txiaj ntsig kev xeem, saib ntawm nqe lus yuam kev hauv qab no rau cov npe ntawm cov lej yuam kev thiab txhua qhov txhais tau li cas.
- Yog tias txhua yam zoo li tsis zoo, tej zaum koj tseem xav khiav qhov kev sim txuas ntxiv, uas yog qhov zoo dua ntawm kev nrhiav teeb meem nco thiab duab. Txhawm rau khiav qhov kev xeem txuas ntxiv, xaiv qhov Ua Kev Ntsuas Ntxiv kos lub thawv, tom qab ntawd nyem Test Kev sim txuas ntxiv yuav siv sijhawm ntau dua li qhov ntsuas tus qauv.
- Quit AHT los ntawm nias ib qho Restart lossis Shut Down.
Apple Hardware Test yuam kev Codes
Cov lej yuam kev uas tsim los ntawm Apple Hardware Test zoo li tsis muaj tseeb thiab txhais tau rau Apple cov kws tshaj lij pabcuam. Ntau tus lej yuam kev tau paub zoo, txawm li cas los xij, thiab cov npe no yuav pab tau:
| Error Code | Kev piav qhia |

Kev daws teeb meem ntxiv tactics
Feem ntau ntawm cov lej yuam kev qhia tias tsis ua haujlwm ntawm cov khoom muaj feem cuam tshuam thiab yuav tsum muaj tus kws tshaj lij saib Mac los txiav txim qhov ua rau thiab tus nqi kho. Ua ntej mus rau Apple Store lossis xa koj Mac tawm mus rau lub khw, rov pib dua PRAM thiab rov pib dua SMC. Qhov no tuaj yeem pab tau rau qee qhov yuam kev, suav nrog cov logic board thiab cov teeb meem kiv cua.
Koj tuaj yeem ua qhov teeb meem ntxiv rau lub cim xeeb (RAM), hard disk, thiab teeb meem sab nraud disk. Nyob rau hauv cov ntaub ntawv ntawm ib tug tsav, txawm nyob rau hauv los yog sab nraud, kho nws siv Disk Utility, uas yog suav nrog OS X, los yog ib tug thib peb-tog app xws li DiskWarrior los yog Techtool Pro.
Yog hais tias lub Mac muaj cov neeg siv-kev pabcuam RAM modules, ntxuav thiab rov qhib RAM. Tshem tawm RAM, siv cov cwj mem qhuav los ntxuav cov RAM modules cov neeg sib cuag, thiab rov nruab RAM. Tom qab ntawd, rov ua Apple Hardware Test siv qhov kev sim txuas ntxiv. Yog hais tias lub Mac tseem muaj teeb meem nco, tej zaum koj yuav tau hloov lub RAM.
Yuav ua li cas yog tias koj nrhiav tsis tau AHT Disk lossis USB Flash Drive
Yog tias koj muab qhov chaw kho qhov muag tsis raug lossis USB flash drive, koj muaj ob txoj kev xaiv. Koj tuaj yeem nqa lub Mac mus rau lub khw Apple ze tshaj plaws lossis hu rau Apple thiab xaj kom hloov disk teeb.
Ua ntej koj hu, koj xav tau tus lej xov tooj Mac, uas pom nyob rau hauv Apple ntawv qhia hauv qab About This Mac. Thaum koj muaj tus lej xov tooj, hu rau Apple kev txhawb nqa, lossis siv cov txheej txheem txhawb nqa online los pib thov kev hloov xov xwm.
Lwm qhov kev xaiv yog coj Mac mus rau Apple Store. Apple cov kws tshaj lij tuaj yeem khiav AHT rau koj thiab kuaj xyuas txhua yam teeb meem uas Mac muaj.
