一、如何檢測筆記本電源適配器故障

第1步：首先可通過輕搖電源接頭或電池查看電源適配器或筆記本電(dian)(dian)(dian)池(chi)是否接(jie)觸良好，如(ru)不(bu)正常，嘗試重新安裝電(dian)(dian)(dian)源適配器(qi)或電(dian)(dian)(dian)池(chi)。可能(neng)出現的故障(zhang)情況為電(dian)(dian)(dian)源接(jie)頭變形或電(dian)(dian)(dian)池(chi)觸點彈性下降。

第2步(bu)：如果電源(yuan)或(huo)電池(chi)接頭(tou)良好(hao)，可用萬用表測電源(yuan)適配(pei)器(qi)或(huo)電池(chi)的輸出(chu)(chu)電壓(ya)(ya)，主要查看輸出(chu)(chu)電壓(ya)(ya)是(shi)否穩定，以及(ji)實際(ji)輸出(chu)(chu)電壓(ya)(ya)值與電源(yuan)標(biao)稱(cheng)電壓(ya)(ya)是(shi)否吻(wen)合，如果輸出(chu)(chu)不穩定或(huo)實際(ji)輸出(chu)(chu)電壓(ya)(ya)與產品標(biao)稱(cheng)相差懸殊，則需更換(huan)損壞的電源(yuan)適配(pei)器(qi)或(huo)電池(chi)。

第3步(bu)(bu)：如以上(shang)檢測步(bu)(bu)驟均(jun)顯示正常，則可推斷(duan)故障(zhang)在筆記(ji)本(ben)電(dian)(dian)源(yuan)板(ban)或主板(ban)上(shang)，此處(chu)需打開筆記(ji)本(ben)電(dian)(dian)腦外殼，并(bing)檢查電(dian)(dian)源(yuan)板(ban)與主板(ban)是否接觸良好。

第4步：如果電(dian)源(yuan)板和電(dian)池均接觸良(liang)好(hao)，則用DIY普遍(bian)使用的(de)替(ti)換(huan)法(fa)檢查電(dian)源(yuan)板是(shi)否(fou)正(zheng)常(chang)，如不(bu)正(zheng)常(chang)，更換(huan)即(ji)可。

第5步：如通(tong)過以上方法確認電(dian)源板(ban)、電(dian)池均正常，則可推(tui)斷是筆記本主板(ban)或(huo)其他主部(bu)件損壞（如開機(ji)電(dian)路故(gu)障），此時可維修或(huo)更換主板(ban)。

二、電源適配器壞了怎么辦

1、檢查電源(yuan)適配器指(zhi)標燈，如果指(zhi)示燈亮，一般認為從電源(yuan)到適配器之間沒(mei)有問題，必(bi)須保證是(shi)指(zhi)示燈本身沒(mei)壞。

2、檢查電源(yuan)適(shi)配(pei)(pei)器到電腦(nao)(nao)之間的(de)(de)有(you)沒有(you)電。這個(ge)可(ke)(ke)以通過筆(bi)記(ji)本(ben)(ben)的(de)(de)指示燈(deng)顯示，有(you)電源(yuan)充到筆(bi)記(ji)本(ben)(ben)的(de)(de)時候(hou)，那(nei)個(ge)充電指示燈(deng)會亮。否則，不(bu)會亮。或(huo)者(zhe)找一(yi)個(ge)同品牌的(de)(de)電源(yuan)適(shi)配(pei)(pei)器交換試(shi)試(shi)。用你(ni)的(de)(de)電源(yuan)適(shi)配(pei)(pei)器手對方(fang)筆(bi)記(ji)本(ben)(ben)，如果對方(fang)電腦(nao)(nao)工(gong)作(zuo)正常，則你(ni)的(de)(de)電源(yuan)適(shi)配(pei)(pei)器沒問題(ti)。否則，可(ke)(ke)能你(ni)的(de)(de)電源(yuan)適(shi)配(pei)(pei)器有(you)問題(ti)。如果對方(fang)的(de)(de)電源(yuan)適(shi)配(pei)(pei)器插你(ni)電腦(nao)(nao)上后，你(ni)的(de)(de)電腦(nao)(nao)工(gong)作(zuo)正常，而用自己的(de)(de)電源(yuan)適(shi)配(pei)(pei)器卻不(bu)能正常工(gong)作(zuo)，那(nei)么你(ni)的(de)(de)電源(yuan)適(shi)配(pei)(pei)器有(you)問題(ti)。

3、觀測(ce)電(dian)腦的指示燈(deng)變化(hua)。如果(guo)你插上(shang)電(dian)源適(shi)配器后(hou)，你可(ke)以看到充電(dian)的指示燈(deng)時亮時滅，有時間一直不滅，則(ze)是筆記(ji)本里面(mian)那個(ge)電(dian)源適(shi)配器接(jie)口有問題，一般可(ke)能里面(mian)線(xian)斷了，電(dian)路板老化(hua)，焊接(jie)掉落等原因。此稱為虛焊現象(xiang)。這種情況(kuang)只(zhi)有叫(jiao)專(zhuan)家修(xiu)理了。

三、更多電源適配器常見問題

1、都是同樣標稱電壓的電源，輸出電流不同，能不能用在同一臺筆記本上？

電(dian)(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)(dian)壓(ya)一(yi)(yi)樣(yang)，輸(shu)出電(dian)(dian)(dian)(dian)流(liu)(liu)不(bu)同(tong)，能不(bu)能用(yong)(yong)在同(tong)一(yi)(yi)臺本(ben)(ben)本(ben)(ben)上(shang)。基本(ben)(ben)的(de)(de)(de)(de)(de)(de)(de)原則(ze)是(shi)大(da)標稱電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)可以(yi)代(dai)(dai)(dai)替小標稱電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)。估計(ji)(ji)有(you)人(ren)會(hui)這(zhe)(zhe)樣(yang)想(xiang)(xiang)，覺(jue)得(de)大(da)標稱電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)會(hui)燒壞(huai)本(ben)(ben)本(ben)(ben)，因為電(dian)(dian)(dian)(dian)流(liu)(liu)大(da)了嘛。實際上(shang)電(dian)(dian)(dian)(dian)流(liu)(liu)多大(da)在電(dian)(dian)(dian)(dian)壓(ya)相同(tong)的(de)(de)(de)(de)(de)(de)(de)情況下取(qu)決(jue)于負載，呵呵，想(xiang)(xiang)想(xiang)(xiang)初中的(de)(de)(de)(de)(de)(de)(de)物(wu)理(li)就知(zhi)道了。當本(ben)(ben)本(ben)(ben)高負荷(he)運(yun)轉的(de)(de)(de)(de)(de)(de)(de)時候，電(dian)(dian)(dian)(dian)流(liu)(liu)大(da)些(xie)，本(ben)(ben)本(ben)(ben)進入待機(ji)的(de)(de)(de)(de)(de)(de)(de)時候，電(dian)(dian)(dian)(dian)流(liu)(liu)就小些(xie)，大(da)標稱電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)有(you)足夠(gou)的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)余(yu)量。反之(zhi)，有(you)人(ren)用(yong)(yong)56w的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)代(dai)(dai)(dai)替72w的(de)(de)(de)(de)(de)(de)(de)用(yong)(yong)起來也沒什么問(wen)題(ti)，原因是(shi)通常電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配器(qi)的(de)(de)(de)(de)(de)(de)(de)設計(ji)(ji)留有(you)一(yi)(yi)定的(de)(de)(de)(de)(de)(de)(de)余(yu)量，負載功(gong)(gong)率都要小于電(dian)(dian)(dian)(dian)源(yuan)(yuan)功(gong)(gong)率，所(suo)以(yi)這(zhe)(zhe)種代(dai)(dai)(dai)替在一(yi)(yi)般使用(yong)(yong)上(shang)是(shi)可行(xing)的(de)(de)(de)(de)(de)(de)(de)，但是(shi)剩余(yu)的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)功(gong)(gong)率余(yu)量就很少了，一(yi)(yi)旦你的(de)(de)(de)(de)(de)(de)(de)本(ben)(ben)本(ben)(ben)接了很多外設，比如兩塊usb硬盤，然后cpu全(quan)速(su)運(yun)轉，再有(you)一(yi)(yi)個底座，上(shang)面(mian)來個光驅全(quan)速(su)讀盤，再加上(shang)同(tong)時給電(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)，估計(ji)(ji)就危險了，要隨(sui)時用(yong)(yong)手摸摸你的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)是(shi)不(bu)是(shi)已經可以(yi)煮雞蛋了。所(suo)以(yi)最好不(bu)要用(yong)(yong)小電(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)代(dai)(dai)(dai)替大(da)電(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)。

2、一模一樣的機器，別人的電源溫溫的，我的總是很燙，為什么？

先(xian)不要懷(huai)疑你的(de)(de)電源有問題，先(xian)看(kan)看(kan)你的(de)(de)本(ben)本(ben)在(zai)(zai)干什(shen)么，是(shi)不是(shi)像上面說的(de)(de)兩(liang)塊(kuai)USB硬盤(pan)，CPU全(quan)速運轉，硬盤(pan)瘋(feng)狂(kuang)讀寫，光(guang)驅全(quan)速讀盤(pan)，同時給電池(chi)充電，大(da)聲放著(zhu)音樂，屏幕亮度(du)最大(da)，無線網(wang)卡一直在(zai)(zai)偵測(ce)信號等(deng)(deng)等(deng)(deng)，善用電源管理，根(gen)據任務(wu)合理調(diao)整本(ben)本(ben)的(de)(de)工作狀態是(shi)很重要的(de)(de)。

3、電源標稱電壓比我的本本電池電壓高很多，不會出事吧？

首先(xian)，要知道的是，電(dian)(dian)(dian)源給本(ben)(ben)本(ben)(ben)供電(dian)(dian)(dian)與電(dian)(dian)(dian)池給本(ben)(ben)本(ben)(ben)供電(dian)(dian)(dian)是不(bu)同的。

電(dian)(dian)(dian)池(chi)(chi)供(gong)電(dian)(dian)(dian)，電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)輸出是(shi)純直流，干凈得很(hen)，電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)壓(ya)既(ji)不可能也不需要設計得很(hen)高，鋰(li)電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)化學特性決定了一(yi)(yi)節電(dian)(dian)(dian)芯的(de)(de)(de)輸出電(dian)(dian)(dian)壓(ya)只(zhi)能在(zai)3。6V左右，所以很(hen)多電(dian)(dian)(dian)池(chi)(chi)都是(shi)采(cai)用三級串聯(lian)的(de)(de)(de)方式，10。8V也就成了很(hen)流行的(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)壓(ya)。有些電(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)標(biao)稱值比3。6V的(de)(de)(de)整數倍稍大一(yi)(yi)些，比如(ru)3。7V或者11。2V等等，其實是(shi)為了保護電(dian)(dian)(dian)池(chi)(chi)。

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，情(qing)況(kuang)就復(fu)(fu)雜一些，首先需(xu)要對加入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)進(jin)行(xing)進(jin)一步的(de)(de)穩(wen)壓(ya)(ya)(ya)濾波，以(yi)保證在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源性(xing)能不(bu)很(hen)好的(de)(de)情(qing)況(kuang)下穩(wen)定工(gong)(gong)作，穩(wen)壓(ya)(ya)(ya)后(hou)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)分(fen)成(cheng)兩(liang)個(ge)部分(fen)，一路給(gei)(gei)本(ben)本(ben)工(gong)(gong)作供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，另一路給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，給(gei)(gei)本(ben)本(ben)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)那部分(fen)同電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)時(shi)候相同，而給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)那部分(fen)需(xu)要通(tong)過電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)控(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路才可以(yi)加在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯上，控(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路可以(yi)很(hen)復(fu)(fu)雜，所(suo)以(yi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)必(bi)須大于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)才有充(chong)分(fen)的(de)(de)能力供(gong)(gong)應給(gei)(gei)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)控(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路的(de)(de)各單元。最后(hou)真正加到電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)芯上的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)決不(bu)會是(shi)你的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源標稱的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)。

上面為大家詳細介紹了筆記本電源適配器故障檢測，以及(ji)筆(bi)記本(ben)電(dian)源適配(pei)器壞了怎(zen)么修(xiu)的(de)(de)相(xiang)關內容，筆(bi)記本(ben)電(dian)腦電(dian)源適配(pei)器是我們工作生活中(zhong)都(dou)比較(jiao)常(chang)用的(de)(de)，所以了解相(xiang)關知識(shi)，更有利于安全(quan)便捷的(de)(de)使用電(dian)源適配(pei)器。
