Cov keyboard thiab nas yog cov khoom siv sib piv. Cov laj thawj rau lawv qhov tsis khov tuaj yeem yog qhov ua haujlwm tsis yooj yim ntawm cov cuab yeej lawv tus kheej lossis cov niam tsev, nrog rau cov kev ua yuam kev ntawm kev ua haujlwm.
Kev ua haujlwm tsis zoo
Kev ua haujlwm ntawm cov kab ke ua haujlwm tsis zoo cuam tshuam rau kev ua haujlwm ntawm cov khoom siv nruab nrab pom tom qab lub OS tseem ua haujlwm. Txheeb xyuas cov ntawv keyboard tsis raug nyob rau hauv BIOS (Basic Input / Output System). Txhawm rau ua qhov no, tom qab thawj zaug kho vajtse pov npav thiab POST beep, nias F10 lossis Delete qhov tseem ceeb, nyob ntawm BIOS version, thiab qhib cov ntawv qhia cov khoom siv ib los ntawm ib qho. Yog tias cov keyboard tsis ua haujlwm, qhov teeb meem no yog teeb meem txuj.
Yog tias koj muaj nas thiab cov keyboard nrog ps / 2 txuas (me me 6 lub xov tooj), nco ntsoov tsis txhob sib tov nrog cov nas thiab cov keyboard ports thaum sib txuas. Lawv tau cim nrog cov xim lossis cov duab ntawm cov khoom siv no. Nco ntsoov tias cov pins hauv cov txuas tsis raug khoov thiab tsis tawg. Kuaj puas yog cov nas thiab cov keyboard puas ua haujlwm nyob rau lwm lub computer.
Txuas cov cuab yeej txuas rau ps / 2 cov txuas tsuas yog thaum lub hwj chim tsis ua hauj lwm, txwv tsis pub lub Circuit Court luv yuav ua rau puas chaw nres nkoj.
Tus choj nyob sab qab teb ntawm lub chaw nkoj taws yuav kub siab dhau. Tshem tawm cov khoom vaj huam sib luag sab ntawm chav kaw lus thiab pom 2 lub microcircuits loj loj rau ntawm cov niam. Sim cov hauv qab kom zoo. Yog tias lub microcircuit yuav kub heev, nws ua rau pom kev hu rau cov kev pabcuam computer.
Tshem cov roj teeb round uas ua rau lub ROM nti los ntawm lub qhov (socket) ntawm motherboard. Siv cov ntsia hlau ntsia hlau rau kev sib tshooj ntawm cov hluav taws xob hauv qhov txuas rau ob peb feeb kom rov pib kho qhov BIOS rau lub Hoobkas tso dag. Qhov no yuav pab tau yog tias koj ua tsis tiav qee yam hloov hauv Teeb.
Kev khiav haujlwm ntawm lub system ua yuam kev
Cov nas thiab cov keyboard tuaj yeem khov vim muaj kab mob. Rub tawm lub LiveCD duab nrog cov khoos kas tiv thaiv kab mob los ntawm DrWeb lossis AVP cov chaw thiab hlawv nws mus rau CD. Hauv BIOS, tsim kev txiav txim rau khau raj los ntawm CD lossis DVD tsav thiab boot lub computer ntawm lub disc. Tshawb xyuas cov kab ke nrog tshuaj thaiv kab mob.
Yog hais tias tus nas thiab cov keyboard khov thaum muab khau raj los ntawm LiveCD, qhov teeb meem yog nrog cov khoom siv ntawd lossis nrog cov motherboard.
Cov laj thawj rau thaiv yuav raug ntsia tsis raug tsav cov tsav tsheb lossis lwm cov haujlwm. Qhib koj lub khoos phis tawm thiab nias F8 tom qab lub POST teeb liab los nqa lub pob Windows khau raj xaiv. Yog tias koj muaj Windows 8, siv Shift + F8 yuam sij los nqa cov ntawv qhia ua zaub mov. Xaiv cov khoom "Hom Safe". Yog tias cov cuab yeej cuam tshuam rau koj cov kev ua hauv kev nyab xeeb, tshem tawm cov software uas nyuam qhuav tsim tiav.
Nias Win thiab hauv tshooj "Programs" xaiv "Accessories", tom qab ntawd "Cov Cuab Yeej System" thiab "System Restore". Ua raws li cov lus qhia ntawm lub vijtsam rov ua haujlwm, nyob ntawm cov khoos phis tawj ntawm qhov rais, hais kom meej cov chaw kuaj ze tsim hnub.
