Sebenzisa i-powercfg kanye nerejista ukulawula ukonga amandla kuma-port e-USB

Emigqeni elandelayo sizobona ngokuningiliziwe ukuthi kanjani Sebenzisa i-powercfg kanye ne-Windows Registry ukuze ukhubaze ngokukhetha ukonga amandla kuma-port e-USBIyini imiphumela yokusetshenziswa? Yiluphi ulwazi olunikezwa umbiko? powercfg /energy futhi kuziphi izimo lapho kufanelekile ukukhubaza le misebenzi, ikakhulukazi kumakhompyutha amalaptop lapho yonke iminithi yokuphila kwebhethri ibalulekile.

Kuyini i-USB selective suspend futhi iyithinta kanjani isistimu?

Okubizwa ngokuthi i-selective suspension ye-USB kuyisici se-Windows esivumela Uhlelo luzocima idivayisi ngayinye ye-USB uma lubona ukuthi ayisebenzi.Isilawuli sonke kanye ne-port akucinywanga, kucinywa kuphela idivayisi ethile engasetshenziswa, ukuze kongiwe amandla ngendlela ephumelelayo.

Uma i-selective suspend ivuliwe futhi isilawuli se-USB siyayisekela, I-Windows iyala amadivayisi angathumeli noma angamukeli idatha ukuthi angene esimweni samandla aphansiNgaleso sikhathi, idivayisi "iyalala" futhi iyeke ukudinga umsebenzi weprosesa, okuvumela i-CPU ukuthi ishintshele ezimweni zamandla aphansi.

Lapho nje idivayisi isidingeka futhi (isibonelo, uhambisa igundane le-USB noma ucindezela inkinobho kukhibhodi yangaphandle), Uhlelo luvusa idivayisi kuleso simo sokumiswa bese luqala ukusebenza kwayo okuvamile.Lonke lolu hlelo luvame ukucaca kumsebenzisi uma hardware futhi abalawuli basetshenziswe kahle.

Inzuzo enkulu yalesi sici ukuthi, kukhompyutha enezingxenye eziningana ezixhunyiwe, Uma wonke amadivayisi e-USB emiswe kahle futhi uhlelo luphumulile, i-CPU cishe ayinawo umsebenzi okufanele iwenze.Lokhu kuyivumela ukuthi ingene ezindleleni zamandla aphansi kakhulu futhi ithuthukise kakhulu impilo yebhethri, ikakhulukazi kuma-laptop.

Ngaphambi kokuthi ucabange ukuthi konke kuhamba kahle, kunconywa kakhulu Qinisekisa ukuthi abashayeli be-USB kanye namadivayisi ngokwawo asebenzisa kahle i-selective suspend.Lokhu kungenziwa kusetshenziswa i-USB-specific Event Trace for Windows (ETW) noma, kalula, imibiko evela kuthuluzi le-PowerCfg.

I-PowerCfg ne-ETW: amathuluzi okuthola izinkinga zamandla e-USB

I-Windows ifake uhlelo lokusebenza olunamandla kakhulu iminyaka eminingi olubizwa ngokuthi I-PowerCfg, okwenziwa kusukela kumugqa we imiyalo Ingasetshenziswa ukufaka ohlwini, ukubuyekeza, nokushintsha cishe noma iyiphi inqubomgomo yamandla esistimu. Kungummese we-Swiss Army wokonga amandla (noma ukuchitha imali) ku-Windows.

Ngaphezu kokushintsha izikhathi zokulala noma ukuvala i-monitor, i-PowerCfg ihlanganisa uchungechunge lwe- ukuthuthukiswa okuhloselwe ukuthola izinkinga zokusebenzisa kahle amandlaKonke lokhu kuyasebenza ngokusebenzisa inketho /energy, eyenza ukuhlaziywa kwemizuzwana engama-60 futhi ikhiqize umbiko we-HTML onamaphutha, izixwayiso, kanye nezincomo.

Ngesikhathi esifanayo, onjiniyela abathuthukile nabaphathi bangasebenzisa I-ETW eqondene ne-USB (Ukulandelela Imicimbi ye-Windows) Lokhu kwenzelwa ukuqopha ukuziphatha kwezinga eliphansi kwabalawuli be-USB namadivayisi. Lokhu kusenza sikwazi ukuqinisekisa ukuthi amadivayisi angena kahle yini kumodi yokulala ekhethiwe, avuke ngesikhathi okufanele avuke ngaso, nokuthi ngabe kukhona yini umshayeli ovimbela izimo zamandla aphansi.

Lokhu kuwusizo ikakhulukazi ezindaweni zobungcweti noma zelebhu, lapho Inhloso ukuqinisekisa ukuthi amadivayisi e-USB ahlangabezana nokulindelwe okonga amandla ngaphambi kokuwathumela kumsebenzisi wokugcina.Kukhompyutha yasekhaya, umkhuba ojwayelekile kuzoba ukunamathela ekusebenziseni powercfg /energyokunikeza ulwazi olwanele ezimweni eziningi.

I-PowerCfg iphinde ihlukanise okutholakele ngamazinga ahlukene obukhali, ihlukanise phakathi amaphutha abucayi, izixwayiso, kanye nolwazi olululaLezo ezihlobene ne-USB zivame ukuvela njenge-"USB Suspend: idivayisi ye-USB engafaki i-selective suspend" noma imibhalo efana kakhulu.

Indlela yokukhiqiza nokuqonda umbiko we-powercfg /energy

Ukuze uhlole ukusebenza kwamandla kwesistimu yakho, okuhlanganisa nokwezimbobo ze-USB, ungakha umbiko wokuxilonga ngokusebenzisa I-PowerCfg ene-/energy modifier evela kukhonsoli enamalungelo okuphathaKuyinqubo elula enikeza amathuba amaningi.

Kufanele uvule nje Uphawu lwesistimu o I-PowerShell njengomlawuli (chofoza kwesokudla → Sebenzisa njengomlawuli) bese uqalisa umyalo:

powercfg /energy

Ngemva kwemizuzwana engaba ngu-60 yokuhlaziywa, i-Windows izodala ifayela le-HTML (ngokuvamile kufolda yomsebenzisi noma endleleni echazwe yi-console) ngesifinyezo esiphelele kakhulu. Kulowo mbiko, Izinkinga ezibalwe zifaka phakathi ukusetshenziswa okungasebenzi kahle kwe-USB selective suspend, ukusetshenziswa kwe-CPU ngokweqile, izilungiselelo zamandla ezingasebenzi kahle, kanye nokuwohloka kwebhethri..

Isibonelo, ibhulokhi efana nalena ivame ukuvela uma kukhona izingxabano nge-USB suspend:

“Ukumiswa kwe-USB: idivayisi ye-USB engangeni ekumisweni okukhethayo”Imininingwane efana negama ledivayisi (isb., “Idivayisi Yokufaka ye-USB”), isihlonzi sesilawuli somsingathi (PCI\VEN_8086&DEV_9D2F), indawo yayo ebhasini le-PCI, i-ID yedivayisi (USB\VID_1BCF&PID_08A0) kanye nomzila wechweba.

Lesi saziso sisho ukuthi leyo divayisi ethile ayizange ifake ukumiswa okukhethiwe ngesikhathi sokuhlaziyaLokhu kungavimbela i-CPU ukuthi ingene ezimweni ezithile zamandla aphansi. Umbiko ngokwawo uvame ukukhombisa ukuthi le nkinga ayivimbeli uhlelo ukuthi lungene kwimodi yokulala, kodwa ithinta ukusebenza kahle ngenkathi uhlelo luvuliwe.

Umbiko ofanayo ungase ube namaphutha ahlobene nenqubomgomo yamandla, njenge: el tiempo Imodi yokulinda yokungena kwimodi yokulala ikhutshaziwe kungakhathaliseki ukuthi idivayisi inamandla ebhethri noma ixhunyiwe.Lokhu kusho ukuthi idivayisi ayikaze isebenzise ngokuzenzakalelayo imodi yokulala, noma ngabe ingasetshenziswa amahora amaningi.

Elinye ibhulokhi elijwayelekile libhekisela ekusetshenzisweni okujwayelekile kweprosesa ngesikhathi sokuhlaziya. Uma i-PowerCfg ithola lokho I-CPU ihlale inamanani aphezulu (isibonelo, isilinganiso esingu-19-20%).Lokhu kuzobonisa ukuthi ukusetshenziswa kuzoba phezulu nokuthi kuyalulekwa ukuthi kubukezwe ukuthi yiziphi izinqubo ezilayisha uhlelo.

Amadivayisi nabalawuli abakhulisa ukusetshenziswa kwamandla

Ngaphezu kwezinkinga ezithile zokumiswa kwe-USB, umbiko mayelana amandlacfg / amandla ngokuvamile uhlu amadivayisi lapho umshayeli wawo engekho, engalungiselelwe kahle, noma enenye inkingaNakuba ekuqaleni kungase kubonakale kungahlobene nokusetshenziswa, kungaba nethonya eliqondile.

Amaqembu amaningi aphinda okufakiwe okufana nokuthi “Izinsiza zebhodi lomama"ngezihlonzi zohlobo ACPI\PNP0C02\1, ACPI\PNP0C02\2, ACPI\PNP0C02\5, ACPI\PNP0C02\PCHRESV, ACPI\PNP0C02\SARESV, ACPI\PNP0C02\IOTRAPS noma ngisho ACPI\INT340E\2&DABA3FF&0.

Lezi zinto, kanye namadivayisi amakwe ngokuthi “Idivayisi Eyigugu” (ACPI\INT0800\4&168ECC8&0), Lokhu kuvame ukufana nezinsizakusebenza ze-chipset zangaphakathi noma abalawuli be-ACPI i-Windows ebheka ukuthi basesimweni esingaphansi kwesilinganiso.Umbiko uxwayisa ngokuthi lezi zinkinga zingandisa ukusetshenziswa kwamandla ngisho noma imishini ibonakala isebenza kahle.

Kuvamile futhi ukuthi i-PowerCfg ibonise ukuthi Ukuphathwa kwamandla kwe-PCI Express active-state (ASPM) kukhutshaziwe ngenxa yokungahambisani kwehadiwe okwaziwayoLokhu kunciphisa ikhono lamadivayisi e-PCIe lokunciphisa ukusetshenziswa kwamandla awo uma engasetshenziswa ngokugcwele, okubuye kuthinte impilo yebhethri.

Kwezinye izimo umbiko uhlanganisa ngisho nesixwayiso sokuthi “Ukusetshenziswa kwe-CPU: iphutha lokuhlaziyaLokhu kubonisa ukuthi inqubo yokuxilonga ayikapheli, yize imiphumela ethile engaphelele ikhonjiswa. Noma kunjalo, idatha etholakalayo ivame ukwanele ukuqondisa ukulungiswa kwamandla.

Lonke lolu hlu lwezaziso nezixwayiso lunikeza umbono ocacile wokuthi Yiziphi izingxenye zesistimu ezivimbela imishini ukuthi ifinyelele amazinga ayo angcono kakhulu okusebenzisa kahle amandla?Eziningi zalezi zinkinga zingaxazululwa ngokushintsha izinqubomgomo zamandla nge-PowerCfg. Uma inkinga ikhomba ukwehluleka kokuqashelwa, kungcono ukubuyekeza iziqondiso [ngesihloko esifanele].

Sebenzisa i-PowerCfg ukushintsha noma ukukhubaza ukonga amandla

Nakuba abantu abaningi bephatha izinhlelo zamandla kusuka kuphaneli yezithombe zeWindows, umyalo powercfg.exe Inikeza ukulawula okukhulu kanye nesivinini, ikakhulukazi uma ufuna ukusebenzisa ukucushwa okufanayo kumakhompyutha amaningana noma ezindaweni zelebhu.

Lolu hlelo lokusebenza luvele okokuqala ku- I-Windows XP SP2 futhi isasebenza ngokugcwele ezinguqulweni zesimanje ezifana ne-Windows 10, Windows 11 ngisho ne-Windows ServerKodwa-ke, ukuze uyisebenzise kufanele uvule ikhonsoli (I-CMD noma i-PowerShell) enamalungelo okuphatha.

I-PowerCfg ayigcini nje ngokuvula noma ukuvala ukonga amandla, kodwa Ikuvumela ukuthi ulungise isikhathi sokuvala isikrini, ukulala, ubusika, izilungiselelo zediski, ukukhetha uhlelo lwamandla, ukucushwa kweprosesa, nokunye okuningi.Kuyithuluzi eliphelele kakhulu okufanele ukulazi.

Uma ufuna Buka zonke izinketho ezitholakalayoMane nje uthayiphe:

powercfg /?

Ezimweni ezithile, njengase- amalabhorethri, amakilasi, izindawo zokuhlola, noma imishini okumele ihlale isebenzaUngase ufune ukukhubaza ngokuphelele ukonga amandla ukuze uvimbele uhlelo ukuthi lungazicimi ngokuzenzakalelayo izikrini, amadiski, noma luye kwimodi yokulala.

Isibonelo esijwayelekile sokucushwa kwe- shiya iqembu "lihlale livukile" Lokhu kuzobandakanya ukwenza lolu chungechunge lwemiyalo:

c:\windows\system32\powercfg.exe -change -monitor-timeout-ac 0
c:\windows\system32\powercfg.exe -change -monitor-timeout-dc 0
c:\windows\system32\powercfg.exe -change -disk-timeout-ac 0
c:\windows\system32\powercfg.exe -change -disk-timeout-dc 0
c:\windows\system32\powercfg.exe -change -standby-timeout-ac 0
c:\windows\system32\powercfg.exe -change -standby-timeout-dc 0
c:\windows\system32\powercfg.exe -change -hibernate-timeout-ac 0
c:\windows\system32\powercfg.exe -change -hibernate-timeout-dc 0
c:\windows\system32\powercfg.exe /hibernate off

Ngalezi zilungiselelo, Zonke izibali-sikhathi ezihlobene ne-monitor, idiski, ukulala kanye ne-hibernation azisebenzi, kungakhathaliseki ukuthi zixhunyiwe noma zisebenza ngamandla ebhethri.Futhi umsebenzi wobusika uqobo uvaliwe. Lokhu akukhuthazwa ukusetshenziswa nsuku zonke kuma-laptop, kodwa kuyasiza kumadivayisi adinga ukuhlala evuliwe njalo.

Ukumiswa kwe-USB okukhethiwe ku-Windows 11: izinzuzo kanye nokungalungi

Ngokufika kwe-Windows 11, isici se- Ukumiswa kwe-USB okukhethiwe sekuthole ukuvelela okukhulu nakakhulu, njengoba uhlelo luhloselwe kakhulu ukulinganisela ukusebenza kanye nokusebenza kahle, ikakhulukazi kwihadiwe yesimanje ephathekayo.

Lesi sici sinesibopho sokwenza phatha amandla edivayisi ye-USB ngendlela ehlanganisiwengokuvala kuphela lawo madivayisi angasetshenziswa njengamanje. Umgomo ukunciphisa ukusetshenziswa kwamandla okuphelele nokwandisa isikhathi sebhethri ngaphandle kokuba umsebenzisi akhathazeke nganoma yini.

Kodwa-ke, kwamanye amakhompyutha noma ngezingxenye ezithile, le nqubomgomo ingabangela ukuziphatha okucasulayo: Amagundane e-USB noma amakhibhodi athatha isikhashana ukuphendula, ama-hard drive angaphandle "awakhuphula" wona, amadivayisi abonakala enqamula futhi exhuma kabusha ngaphandle kwencazelo, Njll

Kulezo zimo, kunengqondo ukucabangela Khubaza i-USB selective suspension ukuze ubeke phambili ukuzinza nokuphendula kunokonga amandlaAkuyona inketho ephumelela kakhulu, kodwa ngezinye izikhathi yikho okwenza umehluko phakathi kwedivayisi esebenzisekayo neyicasulayo.

Kufanele futhi kuqashelwe ukuthi, nakuba ukumiswa okukhethiwe kuhloselwe ukusiza, Idrayivu ye-USB enephutha noma i-firmware epholishwe kabi ingabangela ukuphathwa kwamandla ukuthi kuholele emaphutheni, ekunqanyulweni, noma ngisho nasekuphahlazekeni.Yingakho abanye abasebenzisi bekhetha ukuyikhubaza kuma-port noma kumadivayisi athile.

Izindlela ezisebenzayo zokukhubaza i-USB selective suspension

Uma ubhekene nokunqamuka kwedivayisi okungahleliwe noma izinkinga zokusebenza osola ukuthi zihlobene namandla, kunezindlela eziningana zokwenza Khubaza ukumiswa kwe-USB okukhethiwe noma ukonga amandla okuhlobene namachwebaKungenziwa kusukela ku-interface yesithombe, kusukela ku- Umlawuli wedivayisi, usebenzisa umyalo osheshayo futhi, ezimweni ezithile kakhulu, ngokulungisa iRegistry.

Enye yezindlela ezivame kakhulu ukuya ku- Vula i-Windows Control Panel yakudala, bese ukhetha i-Power Options bese uhlela izilungiselelo ezithuthukisiwe zohlelo olusebenzayo.Ngaphakathi kwalowo muthi wezinketho, kunesigaba esithile se-"USB Configuration" kanye nesinye se-"USB Selective Suspend Configuration." Ukushintsha lelo nani libe yi-"Disabled" kuphoqa uhlelo ukuthi lungamisi amadivayisi.

Enye indlela ukusebenzisa i- Umlawuli wedivayisi Ukuze ulungise izilungiselelo zamandla zedivayisi ngayinye ye-USB, vula izakhiwo zehabhu le-USB noma idivayisi ethile. Ngokuvamile kunethebhu ethi "Ukuphathwa Kwamandla" lapho ungasusa khona ukumaka ebhokisini elithi "Vumela ikhompyutha ukuthi ivale le divayisi ukuze wonge amandla."

Izinguquko zomhlaba wonke zingasetshenziswa kusetshenziswa umyalo osheshayo. Ukuqalisa imiyalo ye-powercfg eguqula izinketho zohlelo olusebenzayo, kungenzeka ukukhubaza nge iskripthi Ukumiswa okukhethiwe kuyo yonke imishini enhlanganweni, into ewusizo kakhulu ezindaweni zezinkampani.

Ezimweni ezithuthukile kakhulu, futhi kuphela uma wazi kahle ukuthi wenzani, lapho ungaphendukela khona I-Windows Registry ukushintsha okhiye abalawula ukusebenza kwamandla e-USBLokhu kuvumela ukulungiswa okuncane kakhulu noma ukuzenzekela kwezinqubomgomo ngokusekelwe kuma-port noma kumadivayisi, yize kungeyona indlela enconywayo kubasebenzisi abangenalo ulwazi oluningi.

Kukhona ngisho nalabo abafuna Izikripthi ze-PowerShell ezikhubaza ngokuzenzakalelayo inketho ethi "vumela ikhompyutha ukuthi ivale idivayisi ukuze yonge amandla" isikhathi ngasinye lapho idivayisi entsha ye-USB ixhunyiwe.Lokhu kungenxa yokuthi uma uyixhuma kwenye imbobo, uhlelo luphinda lusebenzise amanani azenzakalelayo bese ibhokisi livela lihloliwe futhi.

Uma inkinga ibhethri: isibonelo sangempela sisebenzisa i-powercfg /energy

Icala elivamile kakhulu yileli labasebenzisi abaqaphela lokho I-laptop yakho ilahlekelwa yibhethri ngokushesha okukhulu, ivala ngokuzumayo cishe ngo-30%, noma ikhipha amanzi ngokushesha kakhulu ngisho noma ingasebenzi.Uma uqala ukubheka, Umphathi Womsebenzi Ngokuvamile akubonisi lutho olungavamile, futhi konke kukhomba inkinga yehadiwe.

Kodwa-ke, uma uhlola imishini efanayo nenye ipulatifomu, njengokusabalalisa Linux isitayela sesimanje se-Fedora, Impilo yebhethri ithuthuka kakhulu futhi ukuvala okungazelelwe kuyanyamalala.Lokhu kusikisela ukuthi umsuka wokwehluleka usekucushweni noma abashayeli IWindows

Esimweni esinjalo, sebenzisa powercfg /energy Uma imishini ixhunyiwe, ingakhanyisa kakhulu. Umbiko uvame ukukhombisa Amaphutha enqubomgomo yamandla, izexwayiso zokumiswa kwe-USB, ukusetshenziswa kwe-CPU okuphezulu kunokulindelekile, kanye namadivayisi amaningana e-ACPI anezinkinga zomshayeli.

Isibonelo, kungase kuvele amaphutha abonisa ukuthi Isikhathi sokuvala ngaphambi kokungena kwimodi yokulala siyakhutshazwa kokubili uma idivayisi inamandla ebhethri kanye nalapho ixhunywe emthonjeni wamandla.Lokhu kusho ukuthi i-laptop ayilokothi ilale yodwa, noma ngabe uyishiya ingasebenzi inesivalo sivuliwe futhi ingathinti lutho.

Ibhulokhi lingabonakala lixwayisa ngokuthi Ukusetshenziswa okumaphakathi kweprosesa phakathi nemizuzwana engama-60 yokuhlaziya kwakucishe kube ngu-20%.kuyilapho i-Task Manager ibonise u-6-10%. Lo mehluko ubangelwa ukuthi umbiko ulinganisa ezinye izici futhi ukwenza kucace ukuthi uhlelo "aluthulile" njengoba lubonakala.

Kulokhu kunezixwayiso ze- Amadivayisi e-USB angangeni ekumisweni okukhethayo, i-ASPM ikhutshaziwe ku-PCIe ngenxa yokungahambisani kwehadiwe, kanye nezinsizakusebenza ezahlukahlukene zebhodi lomama ezinekhodi yenkinga engu-0x16Konke lokhu kudala isimo lapho iWindows ingalokothi ifinyelele khona izimo zamandla aphansi, okubangela umthelela ebhethrini.

Uma, ngenxa yezizathu zomsebenzi, ukushintsha uhlelo lokusebenza kungenzeki, ifomethi, Lungisa izinqubomgomo zamandla nge-PowerCfg, khubaza ngokukhetha i-suspend kumadivayisi athile e-USB anenkinga, bese ubuyekeza abashayeli be-ACPI kanye ne-chipset. Ngokuvamile kuyindlela ewusizo kakhulu yokubuyisa ukuzimela okuthile.

Kunoma ikuphi, umbiko we-PowerCfg uba yindlela ecacile yokuqonda Okufanele ubhekane nakho kuqala: izinhlelo zikagesi, abashayeli, ukumiswa okukhethayo, i-ASPM, njll. Ukusuka lapho, ungazama izinguquko bese uphinda ukuhlaziya kuze kube yilapho uhlu lwamaphutha selunciphile.

I-PowerCfg, Ukubhalisa, kanye Nokuqonda Okujwayelekile Lapho Ulungisa Amandla E-USB

Konke esikubonile kukwenza kucace ukuthi, yize iWindows ihlose ukuthuthukisa amandla ngokuzenzakalelayo, Ukucushwa okuzenzakalelayo akuhlali kufaneleka kakhulu kuwo wonke amadivayisi kanye nabo bonke abasebenzisi.Amachweba e-USB ayisibonelo esihle salokhu kulinganisela okubucayi phakathi kokonga izindleko kanye nokuzinza.

Ngenxa yamathuluzi afana amandlacfg / amandla Kungenzeka ukubona ngokunemba okukhulu ukuthi yini ehlulekayo: uma kukhona Amadivayisi e-USB angamisi, akhubaze ukumiswa kwesikhathi sokuvala, ukusetshenziswa kwe-CPU okuphezulu ngokungavamile, noma abashayeli be-ACPI abandisa ukusetshenziswa kwamandlaUma unalolo lwazi esandleni, kuba lula kakhulu ukwenza izinqumo.

Ukusuka lapho, ukulungiswa kungasetshenziswa kusukela ku-interface yesithombe, i-Device Manager, i-console ene-PowerCfg, ngisho ne-Registry ezimweni ezithile kakhulu. ngokukhetha ukuvimbela ukonga amandla lapho kubangela izinkinga eziningi kunezinzuzoIcebo akusikho ukuya ezingeni eliphezulu lokukhubaza yonke into ngokungakhethi, kodwa ukuthola iphuzu lapho uhlelo luzinzile futhi, ngesikhathi esifanayo, lusebenza kahle ngokufanele.
