手機開不了機的原因

1、開機(ji)線不(bu)正(zheng)常引(yin)起的不(bu)開機(ji)

正常情況下，按下手機開(kai)機鍵(jian)(jian)時(shi)，開(kai)機鍵(jian)(jian)的(de)觸發端(duan)電(dian)(dian)壓(ya)應(ying)有明顯變化，若(ruo)無變化，一(yi)般是(shi)(shi)開(kai)機鍵(jian)(jian)接觸不(bu)(bu)良(liang)或者是(shi)(shi)開(kai)機線(xian)(xian)斷線(xian)(xian)、元件虛(xu)焊、損壞。維修時(shi)，用外接電(dian)(dian)源供電(dian)(dian)，觀察(cha)電(dian)(dian)流(liu)表的(de)變化，如(ru)果電(dian)(dian)流(liu)表無反應(ying)，一(yi)般是(shi)(shi)開(kai)機線(xian)(xian)斷線(xian)(xian)或開(kai)機鍵(jian)(jian)不(bu)(bu)良(liang)。

2、電池(chi)供電電路不良引起的不開機

對(dui)于大部分(fen)(fen)手(shou)機(ji)(ji)，手(shou)機(ji)(ji)加(jia)(jia)上(shang)(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)或外(wai)接(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源后，供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓直接(jie)加(jia)(jia)到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源工C上(shang)(shang)，如果供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓未加(jia)(jia)到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源IC上(shang)(shang)，手(shou)機(ji)(ji)就不(bu)(bu)(bu)可(ke)(ke)能(neng)開(kai)機(ji)(ji)。對(dui)于摩(mo)托羅拉(la)系列的手(shou)機(ji)(ji)(摩(mo)托羅拉(la)T2688除外(wai))，供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)有(you)所不(bu)(bu)(bu)同，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)和外(wai)接(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)要經過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)開(kai)關轉換再加(jia)(jia)到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源IC上(shang)(shang)。也(ye)就是(shi)說(shuo)(shuo)，手(shou)機(ji)(ji)的供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)有(you)兩條路(lu)(lu)徑，一路(lu)(lu)是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian);另一路(lu)(lu)是(shi)外(wai)部接(jie)口供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(帶(dai)機(ji)(ji)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)座(zuo)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi))。當兩路(lu)(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源同時(shi)(shi)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)時(shi)(shi)，外(wai)部接(jie)口供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)優先。而這兩路(lu)(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源的切(qie)換是(shi)由(you)(you)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)開(kai)關管來控(kong)制，主要達到對(dui)整機(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)起(qi)到保護作用，防止因短路(lu)(lu)或者漏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)對(dui)手(shou)機(ji)(ji)內部的集成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)造(zao)成(cheng)(cheng)損(sun)壞(huai)。但是(shi)，如果電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)開(kai)關損(sun)壞(huai)，中源模塊就有(you)可(ke)(ke)能(neng)得不(bu)(bu)(bu)到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓引起(qi)手(shou)機(ji)(ji)不(bu)(bu)(bu)開(kai)機(ji)(ji)。對(dui)于這種由(you)(you)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)開(kai)關供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的手(shou)機(ji)(ji)，由(you)(you)于既可(ke)(ke)以用外(wai)接(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源接(jie)口供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，也(ye)可(ke)(ke)以通過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)觸片用外(wai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源加(jia)(jia)以供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。維(wei)修時(shi)(shi)可(ke)(ke)通過(guo)不(bu)(bu)(bu)同的供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)方式進行供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，以便區分(fen)(fen)故障范圍和確定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)開(kai)關是(shi)否正常。一般來說(shuo)(shuo)，如果供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)不(bu)(bu)(bu)良(liang)(liang)，按開(kai)機(ji)(ji)鍵電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)表會無反應，這和開(kai)機(ji)(ji)線不(bu)(bu)(bu)良(liang)(liang)十分(fen)(fen)相(xiang)似(si)。

3、電源IC不正常引起的不開

手機要正(zheng)常工作，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)要輸(shu)出正(zheng)常的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓供(gong)(gong)(gong)給(gei)負載電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)。在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)IC是(shi)其核心電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)，不(bu)同品(pin)種及型號(hao)的(de)(de)(de)(de)手機(ji)(ji)，供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)方式亦有(you)所不(bu)同，有(you)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)的(de)(de)(de)(de)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)由(you)幾塊(kuai)穩壓管供(gong)(gong)(gong)給(gei)，如愛立(li)信(xin)早期系(xi)(xi)列(lie)(T18之前)手機(ji)(ji)、部分三星(xing)系(xi)(xi)列(lie)手機(ji)(ji)等(deng)。有(you)的(de)(de)(de)(de)卻有(you)一(yi)塊(kuai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)模塊(kuai)直接供(gong)(gong)(gong)給(gei)，如摩托羅拉(la)系(xi)(xi)列(lie)手機(ji)(ji)、諾(nuo)基亞系(xi)(xi)列(lie)手機(ji)(ji)等(deng)。但不(bu)管怎樣，如果電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)IC不(bu)能正(zheng)常工作，就有(you)可能造成手機(ji)(ji)不(bu)開機(ji)(ji)。對于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)IC，重點是(shi)檢查其輸(shu)出的(de)(de)(de)(de)邏輯供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓、13MHz時鐘(zhong)供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓，在(zai)按(an)開機(ji)(ji)鍵的(de)(de)(de)(de)過(guo)程中應能測到(dao)(不(bu)一(yi)定維持住)，若測不(bu)到(dao)，在(zai)開機(ji)(ji)鍵、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)正(zheng)常的(de)(de)(de)(de)情況下，說明電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)IC虛焊、損壞。目前，越(yue)(yue)來越(yue)(yue)多(duo)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)IC采用了(le)BGA封(feng)裝，給(gei)測量(liang)(liang)和維修帶來了(le)很大的(de)(de)(de)(de)負擔，測量(liang)(liang)時可對照(zhao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)原理圖(tu)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)IC的(de)(de)(de)(de)外圍(wei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)的(de)(de)(de)(de)測試點上進行測試。若判(pan)斷電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)IC虛焊或損壞，需(xu)重新植錫、代換，這需(xu)要較(jiao)高的(de)(de)(de)(de)操(cao)作技巧，需(xu)在(zai)實踐(jian)中加以磨練。

4、系(xi)統(tong)對鐘和復位不(bu)正常引起(qi)的不(bu)開機

系統時鐘是CPU正常工作的條件之一，手機的(de)(de)(de)(de)系(xi)統時(shi)鐘(zhong)(zhong)(zhong)一(yi)般采用(yong)(yong)13MHz，13MHz時(shi)鐘(zhong)(zhong)(zhong)不正常(chang)，邏輯(ji)電(dian)(dian)(dian)(dian)(dian)路(lu)不工(gong)作(zuo)，手機(ji)(ji)(ji)(ji)不可能(neng)開機(ji)(ji)(ji)(ji)。13MHz時(shi)鐘(zhong)(zhong)(zhong)信號(hao)(hao)應(ying)(ying)能(neng)達到一(yi)定的(de)(de)(de)(de)幅度并穩定。用(yong)(yong)示(shi)波(bo)器(qi)測(ce)(ce)13MHz時(shi)鐘(zhong)(zhong)(zhong)輸(shu)(shu)出端上(shang)的(de)(de)(de)(de)波(bo)形，如(ru)果(guo)無(wu)波(bo)形則(ze)(ze)檢測(ce)(ce)13MHz時(shi)鐘(zhong)(zhong)(zhong)振(zhen)(zhen)蕩(dang)電(dian)(dian)(dian)(dian)(dian)路(lu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)壓(ya)(對于13MHzVCO，供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)加到13MHzVCO的(de)(de)(de)(de)一(yi)個(ge)腳亡，對于13MHz晶(jing)振(zhen)(zhen)組成(cheng)(cheng)的(de)(de)(de)(de)振(zhen)(zhen)蕩(dang)電(dian)(dian)(dian)(dian)(dian)路(lu)，這個(ge)供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)一(yi)般供給(gei)中(zhong)頻(pin)(pin)(pin)IC)，若(ruo)有(you)正常(chang)電(dian)(dian)(dian)(dian)(dian)壓(ya)則(ze)(ze)為(wei)(wei)13MHz時(shi)鐘(zhong)(zhong)(zhong)晶(jing)體(ti)、中(zhong)頻(pin)(pin)(pin)IC或(huo)13MHzVCO壞。注意(yi)，有(you)的(de)(de)(de)(de)示(shi)波(bo)器(qi)在(zai)晶(jing)體(ti)上(shang)測(ce)(ce)可能(neng)會(hui)使晶(jing)體(ti)停(ting)振(zhen)(zhen)，此時(shi)，可在(zai)探(tan)頭上(shang)串(chuan)接一(yi)個(ge)幾十皮法以下的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)。有(you)條(tiao)件(jian)(jian)的(de)(de)(de)(de)話，最好使用(yong)(yong)代換法進行維修，以節約時(shi)間，提(ti)高(gao)(gao)效率。13MHz時(shi)鐘(zhong)(zhong)(zhong)電(dian)(dian)(dian)(dian)(dian)路(lu)起振(zhen)(zhen)后，應(ying)(ying)確保13MHz時(shi)鐘(zhong)(zhong)(zhong)信號(hao)(hao)能(neng)通過(guo)電(dian)(dian)(dian)(dian)(dian)阻、電(dian)(dian)(dian)(dian)(dian)容(rong)及放(fang)大電(dian)(dian)(dian)(dian)(dian)路(lu)輸(shu)(shu)人到CPU引(yin)腳上(shang)，測(ce)(ce)試(shi)CPU時(shi)鐘(zhong)(zhong)(zhong)輸(shu)(shu)入腳，如(ru)沒有(you)，應(ying)(ying)檢查線路(lu)中(zhong)電(dian)(dian)(dian)(dian)(dian)阻、電(dian)(dian)(dian)(dian)(dian)容(rong)、放(fang)大電(dian)(dian)(dian)(dian)(dian)路(lu)是(shi)否虛(xu)焊或(huo)無(wu)供電(dian)(dian)(dian)(dian)(dian)及損壞。另(ling)外，有(you)些(xie)手機(ji)(ji)(ji)(ji)的(de)(de)(de)(de)時(shi)鐘(zhong)(zhong)(zhong)晶(jing)體(ti)或(huo)時(shi)鐘(zhong)(zhong)(zhong)VCO是(shi)26MHz(如(ru)摩(mo)托羅拉V998、諾基3310手機(ji)(ji)(ji)(ji))或(huo)19.5MHz(如(ru)三(san)星A188手機(ji)(ji)(ji)(ji))，產生的(de)(de)(de)(de)振(zhen)(zhen)蕩(dang)頻(pin)(pin)(pin)率要(yao)經過(guo)中(zhong)頻(pin)(pin)(pin)IC分(fen)頻(pin)(pin)(pin)為(wei)(wei)13MHz后才(cai)供給(gei)CPU。復位(wei)(wei)信號(hao)(hao)也是(shi)CPU工(gong)作(zuo)工(gong)作(zuo)條(tiao)件(jian)(jian)之(zhi)一(yi)，符(fu)號(hao)(hao)是(shi)RESET，簡寫RST，諾基亞乎(hu)機(ji)(ji)(ji)(ji)中(zhong)用(yong)(yong)PURX表示(shi)。復位(wei)(wei)一(yi)般直接由電(dian)(dian)(dian)(dian)(dian)源IC通往CPU，或(huo)使用(yong)(yong)一(yi)專用(yong)(yong)復位(wei)(wei)小集成(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)路(lu)。復位(wei)(wei)在(zai)開機(ji)(ji)(ji)(ji)瞬間存在(zai)，開機(ji)(ji)(ji)(ji)后測(ce)(ce)量(liang)時(shi)己為(wei)(wei)高(gao)(gao)電(dian)(dian)(dian)(dian)(dian)平。如(ru)果(guo)需要(yao)測(ce)(ce)量(liang)正確的(de)(de)(de)(de)復位(wei)(wei)時(shi)間波(bo)形，應(ying)(ying)使用(yong)(yong)雙(shuang)蹤示(shi)波(bo)器(qi)，一(yi)路(lu)測(ce)(ce)CPU電(dian)(dian)(dian)(dian)(dian)源，一(yi)路(lu)測(ce)(ce)復位(wei)(wei)。維修中(zhong)發現，因復位(wei)(wei)電(dian)(dian)(dian)(dian)(dian)路(lu)不正常(chang)引(yin)起的(de)(de)(de)(de)手機(ji)(ji)(ji)(ji)不開機(ji)(ji)(ji)(ji)并不多(duo)見。

5、邏輯(ji)電路不(bu)正常引(yin)起的不(bu)開機

邏輯電路重點檢測CPU對各存儲器的片選信號CE和許可信號OE，這些信號很重要，但關鍵是必須會尋找這些信號，由于越來越多的手機邏輯電路采用了BGA封裝的集成電路，給查找這些信號帶來了很大的困難。有條件的話最好對照圖紙來查找這些信號及其測量點。片選信號是一些上下跳變的脈沖信號，如果各存儲器CE都沒有，說明CPU沒有工作，補焊、重焊、代換CPU或再仔細檢查CPU作的條件是否具備。如果某個存儲器的片選信號沒有，多為該存儲器損壞。如果CE信號都有，說明CPU-F.作正常，故障可能是軟件故障或總線故障以及某個存儲器損壞。手機在使用(yong)中經(jing)常(chang)會(hui)引起(qi)機(ji)板變形，如按(an)按(an)鍵、摔(shuai)、碰等(deng)外力原因會(hui)引起(qi)某些(xie)芯片(pian)(pian)脫焊(han)(han)，一般(ban)補焊(han)(han)或重焊(han)(han)這些(xie)芯片(pian)(pian)會(hui)解(jie)決大部分(fen)問題。當重焊(han)(han)或代換正常(chang)的芯片(pian)(pian)還不(bu)能開機(ji)，并且使用(yong)免拆機(ji)維修儀讀寫(xie)也不(bu)能通(tong)過時，應逐個測量(liang)外圍電路和代換這些(xie)芯片(pian)(pian)。

6、軟件(jian)不正常(chang)引起的不開機

手(shou)機在開機過(guo)(guo)程中，若(ruo)軟件(jian)(jian)通(tong)不過(guo)(guo)就會不開機，軟件(jian)(jian)出錯(cuo)主要是存儲(chu)器資料不正常(chang)(chang)，當線路沒(mei)有明顯斷線時(shi)，可以先代(dai)換正常(chang)(chang)的(de)碼(ma)片(pian)(pian)、版本或重寫(xie)軟件(jian)(jian)，有的(de)芯片(pian)(pian)內電(dian)路會損(sun)壞，重寫(xie)時(shi)則不能通(tong)過(guo)(guo)。重寫(xie)軟件(jian)(jian)時(shi)應將原(yuan)來資料保存，以備(bei)應急修復。

7、其(qi)它原因引(yin)起的不開機

手機(ji)(ji)(ji)不(bu)(bu)開(kai)機(ji)(ji)(ji)故(gu)障(zhang)的(de)(de)原因還有(you)很多，如液(ye)晶顯示屏(ping)不(bu)(bu)良、元件(特別是功(gong)放)短(duan)路等(deng)都(dou)有(you)可(ke)能引起(qi)手機(ji)(ji)(ji)不(bu)(bu)開(kai)機(ji)(ji)(ji)，還有(you)一些機(ji)(ji)(ji)型必(bi)須用到32.768kHz的(de)(de)實時(shi)時(shi)鐘作為碼片時(shi)鐘信號和睡眠時(shi)鐘信號。若32.768kHz實時(shi)時(shi)鐘不(bu)(bu)正常，也可(ke)能造成(cheng)手機(ji)(ji)(ji)不(bu)(bu)開(kai)機(ji)(ji)(ji)。引起(qi)32.768kHz時(shi)鐘不(bu)(bu)正常的(de)(de)因素主要(yao)有(you)時(shi)鐘備(bei)用電(dian)(dian)池(chi)短(duan)路、32.768kHz時(shi)鐘壞等(deng)。所以，在維修手機(ji)(ji)(ji)不(bu)(bu)開(kai)機(ji)(ji)(ji)時(shi)要(yao)結合具體電(dian)(dian)路具體分析，只要(yao)對(dui)手機(ji)(ji)(ji)的(de)(de)原理(li)理(li)解(jie)正確，思路清楚，不(bu)(bu)開(kai)機(ji)(ji)(ji)故(gu)障(zhang)一般都(dou)可(ke)以排除。

手機開不了機如何解決

第一步：檢(jian)查(cha)電池(chi)是(shi)否有電，電池(chi)沒(mei)電了，手機(ji)自然(ran)沒(mei)有動(dong)力去開機(ji)，如(ru)果怎么沖它都不會啟動(dong)的話可(ke)以檢(jian)查(cha)一下充電器是(shi)否工(gong)作(zuo)，接口是(shi)否損壞，用萬(wan)能充充電或檢(jian)測(ce)電量。

第二步(bu)：檢查電池是否(fou)損壞或者壽命已到，電池是消耗品，如(ru)果損壞或者使用不當(dang)導致電池過(guo)早損壞，可(ke)以嘗試換一塊電池，看一看是否(fou)可(ke)以啟(qi)動，如(ru)果問題解決，就需(xu)要(yao)更換電池。

第三(san)步：進水或刷機(ji)(ji)造成(cheng)人(ren)為性損壞(huai)(huai)，這種(zhong)問題(ti)就是自身的原因了，進水的話用(yong)吹風機(ji)(ji)吹一(yi)吹，拆機(ji)(ji)烘烤試(shi)(shi)一(yi)試(shi)(shi)，如(ru)果摔(shuai)壞(huai)(huai)了，內部(bu)零件(jian)損毀(hui)，就需(xu)要找維(wei)修(xiu)中心維(wei)修(xiu)了。如(ru)果刷機(ji)(ji)造成(cheng)無法開機(ji)(ji)，可以重新(xin)刷機(ji)(ji)嘗(chang)試(shi)(shi)恢復。

第四步(bu)：如果基本的方(fang)法(fa)都(dou)嘗(chang)試(shi)過了，還是(shi)無效的話，就(jiu)只(zhi)能(neng)去找專業的維修中心來進行維修，一般無法(fa)開機的故障(zhang)自(zi)己不(bu)好解決，也可(ke)以試(shi)試(shi)搜索，看看有(you)沒有(you)適合你的解決辦法(fa)。

手機開不了機怎么刷機

這里(li)介紹(shao)最簡(jian)單的刷機方式(shi)(shi)：一種(zhong)是使用軟件下載ROM一鍵(jian)在線刷機！另外一種(zhong)是把ROM復制到SD卡里(li)面(mian)然后進入recovery模式(shi)(shi)進行刷機！

1、用軟件一鍵(jian)在線刷(shua)機(ji)：

步驟一、這(zhe)個需(xu)要(yao)安裝一款(kuan)刷機軟件(jian)，這(zhe)個軟件(jian)用的人也(ye)非(fei)常(chang)的多，還有(you)一件(jian)ROOT的功能，刷機也(ye)需(xu)要(yao)ROOT。我們百度搜索“卓大師”，然(ran)后點擊下載安裝。

步驟二(er)、然后(hou)我們在進入自己的手(shou)機(ji)，點(dian)擊設置，然后(hou)點(dian)擊開發人員選項。把USB調試(shi)打開。不同安卓版(ban)本的手(shou)機(ji)打開的位(wei)置也不一樣。自己在設置里面找找就(jiu)能看到。

步驟三(san)、然后把手機(ji)(ji)用數(shu)據線連(lian)接(jie)好(hao)電腦(nao)，然后在打開安裝(zhuang)好(hao)的卓(zhuo)大師，卓(zhuo)大師連(lian)接(jie)手機(ji)(ji)成(cheng)功之后點(dian)擊ROM專區。這里(li)面會(hui)有(you)很多手機(ji)(ji)的刷(shua)機(ji)(ji)包(bao)。找(zhao)一個(ge)適合自己機(ji)(ji)型的刷(shua)機(ji)(ji)包(bao)下載。

步驟四、然后在(zai)按照(zhao)上圖的指示，點(dian)擊下面(mian)的下載狀態(tai)，打開之后就會(hui)看到ROM下載的位(wei)置。

步驟五、然(ran)后(hou)把你下載的(de)ROM的(de)壓縮文件(jian)復(fu)制(zhi)出來。這(zhe)個文件(jian)也可以直接復(fu)制(zhi)到SD卡里面進入recovery模式進行刷機(ji)，下載刷機(ji)包是最重要的(de)。而且(qie)刷機(ji)包呀下載適(shi)合自己機(ji)型的(de)，不然(ran)很容易變磚(zhuan)。

步(bu)驟六(liu)、下載(zai)完之(zhi)后(hou)(hou)會(hui)出現刷(shua)機(ji)的按鈕，或者我(wo)們(men)進(jin)入導航(hang)里面的一鍵刷(shua)機(ji)，選擇好刷(shua)機(ji)包點擊下一步(bu)，選擇是(shi)否備案，然后(hou)(hou)點擊下一步(bu)就坐等(deng)刷(shua)機(ji)成功提示啦。

2、Recovery模(mo)式刷機方法：

步驟一、首先要確定你的手機是否刷入(ru)(ru)了(le)Recovery，如果沒(mei)有的需要刷入(ru)(ru)Recovery才能(neng)進入(ru)(ru)Recovery進行刷機。這里(li)后(hou)續在為大家演示刷入(ru)(ru)Recovery的方(fang)法(fa)。

步驟二、然后我們(men)在進入(ru)設置把(ba)USB調(diao)試關閉掉，把(ba)刷機(ji)包復制到你(ni)的SD卡(ka)里(li)面。關閉了(le)USB調(diao)試才能讀取出來你(ni)的手機(ji)內存(cun)。

步驟三、然(ran)后在進(jin)入recovery模(mo)(mo)式(shi)，進(jin)入recovery模(mo)(mo)式(shi)的按鍵(jian)有的不一樣。有的可(ke)以從電腦控制進(jin)入recovery模(mo)(mo)式(shi)，有的按著開機鍵(jian)+音量鍵(jian)就能(neng)進(jin)入recovery模(mo)(mo)式(shi)。進(jin)入recovery模(mo)(mo)式(shi)之后先清除所有的數(shu)據。

步驟(zou)四、然后我們(men)在清除手機里面的(de)緩存(cun)數(shu)據，這些操作上下就可以使用音量鍵調節。確定就是開機鍵。

步驟(zou)五、然后(hou)我們在(zai)選擇刷機包(bao)，我們是(shi)裝在(zai)SD卡上(shang)(shang)面(mian)的。所以從SD卡上(shang)(shang)面(mian)選擇刷機包(bao)。

步驟六、我們的刷機(ji)包是ZIP文(wen)(wen)件(jian)，點(dian)擊從SD卡上面選擇(ze)ZIP文(wen)(wen)件(jian)。然后選擇(ze)刷機(ji)包的文(wen)(wen)件(jian)點(dian)擊確(que)定即可。

步驟(zou)七(qi)、刷機成功(gong)之后會有成功(gong)的提示(shi)，然后返回重(zhong)啟系(xi)統(tong)即可進入(ru)你(ni)刷的新(xin)系(xi)統(tong)里面了。
