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)池是否接觸(chu)良好(hao)，如不(bu)正常，嘗試重新安裝電(dian)源適配(pei)器或電(dian)池。可(ke)能(neng)出現的故(gu)障情(qing)況(kuang)為電(dian)源接頭變(bian)形或電(dian)池觸(chu)點彈性下降。

第2步：如果電(dian)源(yuan)或電(dian)池接頭良好，可用萬用表測(ce)電(dian)源(yuan)適配器或電(dian)池的輸(shu)出電(dian)壓(ya)，主要查(cha)看輸(shu)出電(dian)壓(ya)是否(fou)穩(wen)定(ding)，以及實(shi)際輸(shu)出電(dian)壓(ya)值與電(dian)源(yuan)標稱電(dian)壓(ya)是否(fou)吻合，如果輸(shu)出不穩(wen)定(ding)或實(shi)際輸(shu)出電(dian)壓(ya)與產品(pin)標稱相差懸殊(shu)，則需更換損壞的電(dian)源(yuan)適配器或電(dian)池。

第3步(bu)：如以上檢(jian)測步(bu)驟均顯示正常，則可推斷故(gu)障(zhang)在(zai)筆(bi)(bi)記本電源板(ban)(ban)或主(zhu)板(ban)(ban)上，此處需打開筆(bi)(bi)記本電腦外殼，并檢(jian)查電源板(ban)(ban)與主(zhu)板(ban)(ban)是(shi)否接(jie)觸良好。

第4步：如果電源板和電池(chi)均接觸良好，則(ze)用DIY普遍使(shi)用的替換(huan)法檢(jian)查電源板是否正常，如不正常，更換(huan)即可。

第5步(bu)：如通(tong)過以上方法確認電(dian)源板、電(dian)池均正(zheng)常，則可推斷是筆記本主板或其他主部件損壞（如開(kai)機電(dian)路故障），此時可維(wei)修或更(geng)換主板。

二、電源適配器壞了怎么辦

1、檢(jian)查電源(yuan)適(shi)(shi)配器(qi)指(zhi)標燈，如果指(zhi)示燈亮，一般(ban)認(ren)為從(cong)電源(yuan)到(dao)適(shi)(shi)配器(qi)之間沒有問題(ti)，必須保證是(shi)指(zhi)示燈本身沒壞(huai)。

2、檢查電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)到電(dian)(dian)(dian)(dian)(dian)(dian)腦(nao)之間的(de)有沒有電(dian)(dian)(dian)(dian)(dian)(dian)。這個(ge)(ge)可(ke)以通過筆(bi)記(ji)本(ben)的(de)指示(shi)燈顯示(shi)，有電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)充到筆(bi)記(ji)本(ben)的(de)時候，那(nei)個(ge)(ge)充電(dian)(dian)(dian)(dian)(dian)(dian)指示(shi)燈會亮。否則，不會亮。或者找一(yi)個(ge)(ge)同(tong)品(pin)牌(pai)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)交換(huan)試試。用你(ni)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)手對(dui)方筆(bi)記(ji)本(ben)，如果(guo)對(dui)方電(dian)(dian)(dian)(dian)(dian)(dian)腦(nao)工(gong)作(zuo)正(zheng)常，則你(ni)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)沒問題。否則，可(ke)能(neng)你(ni)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)有問題。如果(guo)對(dui)方的(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)插你(ni)電(dian)(dian)(dian)(dian)(dian)(dian)腦(nao)上后，你(ni)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)腦(nao)工(gong)作(zuo)正(zheng)常，而(er)用自己的(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)卻不能(neng)正(zheng)常工(gong)作(zuo)，那(nei)么你(ni)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)有問題。

3、觀測電(dian)(dian)腦的指(zhi)(zhi)示燈(deng)(deng)變化(hua)。如果(guo)你插上(shang)電(dian)(dian)源適(shi)(shi)配器后，你可以看到(dao)充電(dian)(dian)的指(zhi)(zhi)示燈(deng)(deng)時(shi)亮時(shi)滅(mie)，有時(shi)間一(yi)直不滅(mie)，則是筆記本里面(mian)那個電(dian)(dian)源適(shi)(shi)配器接口有問題，一(yi)般可能里面(mian)線斷了(le)，電(dian)(dian)路板老化(hua)，焊接掉落等原因。此稱為虛焊現(xian)象。這(zhe)種情況只有叫專家修理了(le)。

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)(dian)源(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)壓一樣，輸出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)不同(tong)，能不能用(yong)(yong)在(zai)同(tong)一臺(tai)本(ben)本(ben)上。基本(ben)的(de)(de)原則是(shi)(shi)(shi)大(da)標稱(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)可(ke)(ke)以(yi)代替(ti)小(xiao)標稱(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)。估計有人會(hui)這樣想，覺得大(da)標稱(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)會(hui)燒(shao)壞本(ben)本(ben)，因(yin)為電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)大(da)了(le)(le)(le)嘛(ma)。實際上電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)多大(da)在(zai)電(dian)(dian)(dian)(dian)(dian)壓相(xiang)同(tong)的(de)(de)情(qing)況下取決于負(fu)(fu)載，呵呵，想想初中的(de)(de)物理就(jiu)知道了(le)(le)(le)。當本(ben)本(ben)高負(fu)(fu)荷運(yun)轉(zhuan)(zhuan)的(de)(de)時候，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)大(da)些，本(ben)本(ben)進入待(dai)機的(de)(de)時候，電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)就(jiu)小(xiao)些，大(da)標稱(cheng)(cheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)有足夠的(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)余量。反之，有人用(yong)(yong)56w的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)代替(ti)72w的(de)(de)用(yong)(yong)起來(lai)也沒(mei)什么問題，原因(yin)是(shi)(shi)(shi)通常電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適配器的(de)(de)設計留有一定的(de)(de)余量，負(fu)(fu)載功率(lv)都要小(xiao)于電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)功率(lv)，所以(yi)這種代替(ti)在(zai)一般使用(yong)(yong)上是(shi)(shi)(shi)可(ke)(ke)行的(de)(de)，但(dan)是(shi)(shi)(shi)剩(sheng)余的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)功率(lv)余量就(jiu)很(hen)(hen)少了(le)(le)(le)，一旦你的(de)(de)本(ben)本(ben)接了(le)(le)(le)很(hen)(hen)多外設，比如兩(liang)塊(kuai)usb硬盤，然后cpu全速運(yun)轉(zhuan)(zhuan)，再(zai)有一個底座，上面來(lai)個光(guang)驅(qu)全速讀盤，再(zai)加上同(tong)時給電(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)，估計就(jiu)危險了(le)(le)(le)，要隨時用(yong)(yong)手摸摸你的(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)是(shi)(shi)(shi)不是(shi)(shi)(shi)已經(jing)可(ke)(ke)以(yi)煮雞蛋(dan)了(le)(le)(le)。所以(yi)最好不要用(yong)(yong)小(xiao)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)代替(ti)大(da)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan)(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？

先不要(yao)懷疑你(ni)的(de)電(dian)源有問題，先看看你(ni)的(de)本(ben)本(ben)在干什么，是不是像上面說的(de)兩塊USB硬盤(pan)，CPU全速(su)運轉，硬盤(pan)瘋(feng)狂讀(du)寫，光驅全速(su)讀(du)盤(pan)，同時給電(dian)池充電(dian)，大聲放著(zhu)音(yin)樂，屏幕亮度(du)最(zui)大，無線網卡(ka)一直在偵測(ce)信號(hao)等等，善(shan)用電(dian)源管理(li)，根據任務(wu)合理(li)調整(zheng)本(ben)本(ben)的(de)工(gong)作狀態是很(hen)重要(yao)的(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)源給(gei)本(ben)本(ben)供電(dian)與電(dian)池給(gei)本(ben)本(ben)供電(dian)是不同的。

電(dian)(dian)池(chi)供電(dian)(dian)，電(dian)(dian)池(chi)的(de)輸出(chu)是(shi)純直流，干凈得(de)很(hen)，電(dian)(dian)池(chi)的(de)電(dian)(dian)壓既不可能(neng)也不需(xu)要設計得(de)很(hen)高(gao)，鋰電(dian)(dian)池(chi)的(de)化學特性決定了一節電(dian)(dian)芯的(de)輸出(chu)電(dian)(dian)壓只能(neng)在3。6V左右(you)，所以很(hen)多電(dian)(dian)池(chi)都是(shi)采用三級(ji)串聯的(de)方(fang)式，10。8V也就成了很(hen)流行(xing)的(de)電(dian)(dian)池(chi)電(dian)(dian)壓。有(you)些(xie)(xie)電(dian)(dian)池(chi)的(de)標稱(cheng)值(zhi)比(bi)3。6V的(de)整數倍稍大一些(xie)(xie)，比(bi)如(ru)3。7V或者11。2V等(deng)等(deng)，其實是(shi)為了保(bao)護電(dian)(dian)池(chi)。

電(dian)(dian)(dian)(dian)源供(gong)電(dian)(dian)(dian)(dian)，情況就復雜(za)一(yi)(yi)些，首(shou)先需要對加入電(dian)(dian)(dian)(dian)壓進(jin)行進(jin)一(yi)(yi)步的(de)(de)(de)(de)(de)穩(wen)壓濾(lv)波，以(yi)保證在電(dian)(dian)(dian)(dian)源性能不很好的(de)(de)(de)(de)(de)情況下穩(wen)定工(gong)作(zuo)，穩(wen)壓后(hou)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)壓分(fen)成(cheng)兩個部分(fen)，一(yi)(yi)路(lu)給(gei)本(ben)本(ben)工(gong)作(zuo)供(gong)電(dian)(dian)(dian)(dian)，另一(yi)(yi)路(lu)給(gei)電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)，給(gei)本(ben)本(ben)供(gong)電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)那部分(fen)同電(dian)(dian)(dian)(dian)池供(gong)電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)時候相同，而給(gei)電(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)那部分(fen)需要通過電(dian)(dian)(dian)(dian)池的(de)(de)(de)(de)(de)充(chong)電(dian)(dian)(dian)(dian)控(kong)制電(dian)(dian)(dian)(dian)路(lu)才(cai)可以(yi)加在電(dian)(dian)(dian)(dian)芯上，控(kong)制電(dian)(dian)(dian)(dian)路(lu)可以(yi)很復雜(za)，所以(yi)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓必須大于電(dian)(dian)(dian)(dian)芯電(dian)(dian)(dian)(dian)壓才(cai)有充(chong)分(fen)的(de)(de)(de)(de)(de)能力供(gong)應給(gei)充(chong)電(dian)(dian)(dian)(dian)控(kong)制電(dian)(dian)(dian)(dian)路(lu)的(de)(de)(de)(de)(de)各單元。最后(hou)真(zhen)正(zheng)加到(dao)電(dian)(dian)(dian)(dian)芯上的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)壓決不會(hui)是你的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源標稱的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)壓。
