Vim li cas tsis yog qhov keyboard

Tsis muaj ib tug nas thiab keyboard yog tsis tau mus siab siv lub computer. Kov cov ntxaij vab tshaus saib rau loj tshwm sim uas yuav npaj cov nws cov tshiab operating system, Microsoft yog tseem prohibitively kim heev. Yog li ntawd tam sim no lub ntsiab neeg siv interface sis raug zoo nrog ib tug computer yog ob tug pab kiag li lawm. Software developers tseem tabtom xav tias yuav lub ntau yam teeb meem, xws li nyob rau hauv lawv cov khoom no yuav ua hauj lwm nrog tsuas yog ib caj npab los yog ib tug keyboard. Cov kev daws teeb meem ua hauj lwm, tab sis rau lub yooj yim ntawm kev siv tsis tau yuav tau.

Yog hais tias koj tsis ua hauj lwm ib tug keyboard thiab ib tug nas, nws yog akin mus rau ib tug kev puas tsuaj. Panic yog txaus siab los ntawm tej yam tsis zoo xav, "txuag tau nyiaj on kev yuav khoom," "Kho yuav tuaj ib tug ntau ntawm cov nyiaj," thiab thiaj on. Ntej ntawm tag nrho, koj yuav tsum coj koj tus kheej nyob rau hauv tes thiab ua tib zoo ntsuam xyuas qhov teeb meem no: nws yog txaus tias lub computer nws tus kheej yog muab rau, yog li ntawd, cov nyiaj txiag nqi, yog hais tias lawv xav tau , yuav tsum tau negligible. Nyob rau hauv qhov tseeb, yog vim li cas yog vim li cas tsis ua hauj lwm ib tug keyboard, ib tug ntau.

Tej zaum ib txhia cov tuaj tshiab yuav tau tag yuav paub tias lub computer keyboard yog tsis cia li ib lub hnab yas los luj nrog ib tug caij nplooj ntoos hlav-loaded nyees khawm (keyboard), thiab ib tug ua kom tiav ntaus nrog nws tus kheej microcontroller. Parse nws, koj yuav saib tau hauv cov nti, thiab ob peb lwm yam kev siv hluav taws xob ntsiab - qhov no yog qhov maub los los yog, yog tias koj xav, ib tug tshwj xeeb microprocessor. Nws cov ntaub ntawv lub khawm presses thiab xa cov ntaub ntawv rau lawv los ntawm qhov chaw nres nkoj nyob rau hauv lub system tsheb npav computer, thiab ces - mus rau daim ntawv thov.

Yog li ntawd, ntawm no lawv yog, tau yog vim li cas vim li cas lub keyboard tsis ua hauj lwm: Txhaum keyboard microcontroller, tawg hlau los yog connector, qhov chaw nres nkoj tsis ua hauj lwm nyob rau hauv ib lub computer, cov tsis ua hauj lwm ntawm qhov kev pab cuam. Txawm yog vim li cas, tus neeg siv yuav tsuas yuav kho nrog ib tug hlau teeb meem. Nyob rau hauv tag nrho cov lwm tus neeg mob yuav tsum tau ntau drastic daws teeb meem. Lub hauv paus ntsiab lus ntawm cov lag luam ntawm lub computer nas yog tseem zoo sib xws: nws muaj nws tus kheej microcontroller.

keyboard breakage yuav ua tau ntawm ob hom: cov keyboard tsis ua hauj lwm thaum booting lub operating system thiab daim ntaub ntawv. Cov kev khiav hauj lwm qhov system siv los tswj nws keyboard tsav tsheb (tshwj xeeb cov kev pab cuam), yog li ntawd yog ib tug ntawm lawv tsis, nws yuav tsis tau kom raug cov txheej txheem rau Pib ntsais koj teeb ntawm cov keyboard microcontroller. Qhov yooj yim cov kua - reinstalling nws. Rau lub qhov rais neeg siv yuav tsum ua raws li txoj kev ntawm "Computer - Properties - Ntaus Manager - Twj remote controls" thiab tshem tawm cov neeg tsav tsheb. Tom qab hais tias, lub kaw lus yuav tsum tau ib tug reboot. Tej zaum nws yuav pab tau rau nruab ib tug neeg tsav los ntawm lub chaw tsim tshuaj paus, piv txwv li, Logitech.

Tseem muaj ntau heev txhaum nyob rau hauv uas tus neeg siv muaj tsis muaj lub tswv yim vim li cas lub keyboard tsis ua hauj lwm. Qhov yooj yim txoj kev los mus txiav txim nws kev kawm - yog mus saib hauv lub xeev ntawm LEDs CapsLock, NumLock thiab ScrollLock. Tam sim ntawd tom qab xa rau lub computer rau ib tug lub sij hawm ntawd lawv mus rau hauv thiab tawm - raws li nws yuav tsum, nyob rau ntawm lub sij hawm no, lub microcontroller kis tus xeem thiab pib ntsais koj teeb lub noj qab haus huv ntawm lawv yooj yim logic circuits.

Tej cov computers yog chiv teem ua hauj lwm nrog cov keyboard PS / 2 standard, thiab los ntawm lub neej ntawd, USB pab kiag li lawm cov nyiaj them yug yog neeg xiam. Nyob rau hauv cov ntaub ntawv no, koj yuav tsum tau txuas mus rau lub computer PS / 2 keyboard thiab configure tag nrho cov kev kawm. Yog hais tias tsis muaj dab tsi tau hloov thiab nws yog tseem paub tsis meej vim li cas cov keyboard yog tsis ua hauj lwm, koj yuav tsum tau txuas mus rau lub computer los ntawm lwm qhov chaw nres nkoj (connector).

Nws tseem pab tau mus tua tag nrho cov pab kiag li lawm kev cob cog rua rau tib lub ports, vim hais tias tej zaum cov keyboard yog tsis txaus hluav taws xob. Rau USB twj remote controls nyob rau hauv lub BIOS yuav tsum lov tes taw rau «EHCI tes-off», tus tshiab operating systems yuav tsis tau nws, thiab cuam tshuam nrog rau tej lag luam los ntawm nws tag nrho cov tsis mozhet.Esli, nws yog pov thawj mus cuag cov keyboard. Khwv tau nyiaj - txhais tau tias tsis ua hauj lwm vim li cas feem ntau keyboard. Tsis - qhov teeb meem nrog lub chaw nres nkoj connector los yog nrog tus maub los.
