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(chi)是(shi)否接(jie)(jie)觸(chu)良好，如不正常(chang)，嘗試重新安裝(zhuang)電(dian)源適配(pei)器或(huo)電(dian)池(chi)。可能出現的故障情況(kuang)為電(dian)源接(jie)(jie)頭變(bian)形或(huo)電(dian)池(chi)觸(chu)點彈性下降。

第2步(bu)：如果(guo)電(dian)源(yuan)或(huo)電(dian)池接(jie)頭(tou)良好(hao)，可用(yong)萬用(yong)表測(ce)電(dian)源(yuan)適配器或(huo)電(dian)池的輸(shu)(shu)出(chu)電(dian)壓(ya)，主要查看(kan)輸(shu)(shu)出(chu)電(dian)壓(ya)是(shi)否穩定，以及(ji)實際輸(shu)(shu)出(chu)電(dian)壓(ya)值與電(dian)源(yuan)標(biao)稱電(dian)壓(ya)是(shi)否吻合，如果(guo)輸(shu)(shu)出(chu)不(bu)穩定或(huo)實際輸(shu)(shu)出(chu)電(dian)壓(ya)與產品(pin)標(biao)稱相(xiang)差懸殊，則需更(geng)換損壞的電(dian)源(yuan)適配器或(huo)電(dian)池。

第3步(bu)：如以上(shang)(shang)檢測步(bu)驟均(jun)顯示正常，則可推斷故障(zhang)在筆(bi)記(ji)本(ben)電源(yuan)板(ban)或主板(ban)上(shang)(shang)，此處需打開(kai)筆(bi)記(ji)本(ben)電腦外(wai)殼，并檢查電源(yuan)板(ban)與主板(ban)是否接觸良(liang)好。

第4步(bu)：如果電(dian)源板(ban)和電(dian)池均接觸良好(hao)，則(ze)用DIY普(pu)遍使用的(de)替換法檢查電(dian)源板(ban)是否(fou)正(zheng)常，如不正(zheng)常，更(geng)換即可。

第5步：如(ru)通過以上方法確認電源(yuan)板、電池均(jun)正常，則可推斷是(shi)筆記本主(zhu)板或其(qi)他主(zhu)部件損壞（如(ru)開(kai)機電路(lu)故障），此時可維修或更換主(zhu)板。

二、電源適配器壞了怎么辦

1、檢(jian)查(cha)電源(yuan)適配(pei)器指(zhi)標(biao)燈，如(ru)果指(zhi)示燈亮，一般認為(wei)從電源(yuan)到(dao)適配(pei)器之間(jian)沒(mei)有問題，必須保證是指(zhi)示燈本身(shen)沒(mei)壞。

2、檢查電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配器到電(dian)(dian)(dian)(dian)(dian)(dian)腦之間的(de)(de)(de)(de)有(you)(you)沒有(you)(you)電(dian)(dian)(dian)(dian)(dian)(dian)。這(zhe)個(ge)可以通(tong)過筆記(ji)(ji)本(ben)(ben)的(de)(de)(de)(de)指(zhi)示燈顯示，有(you)(you)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)充到筆記(ji)(ji)本(ben)(ben)的(de)(de)(de)(de)時候，那(nei)個(ge)充電(dian)(dian)(dian)(dian)(dian)(dian)指(zhi)示燈會亮。否(fou)則(ze)，不會亮。或者找(zhao)一個(ge)同品牌的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配器交換試(shi)試(shi)。用你的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配器手對方筆記(ji)(ji)本(ben)(ben)，如果對方電(dian)(dian)(dian)(dian)(dian)(dian)腦工作正(zheng)(zheng)(zheng)常，則(ze)你的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配器沒問題(ti)。否(fou)則(ze)，可能你的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配器有(you)(you)問題(ti)。如果對方的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配器插你電(dian)(dian)(dian)(dian)(dian)(dian)腦上后，你的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)腦工作正(zheng)(zheng)(zheng)常，而用自己的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配器卻(que)不能正(zheng)(zheng)(zheng)常工作，那(nei)么你的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配器有(you)(you)問題(ti)。

3、觀測電(dian)腦的指示(shi)燈變化。如果(guo)你(ni)插上電(dian)源(yuan)適配器后，你(ni)可(ke)以(yi)看到充(chong)電(dian)的指示(shi)燈時亮時滅，有(you)(you)時間(jian)一(yi)直不(bu)滅，則是(shi)筆(bi)記本里(li)面那個電(dian)源(yuan)適配器接(jie)口有(you)(you)問題，一(yi)般可(ke)能里(li)面線斷了(le)，電(dian)路板老化，焊接(jie)掉(diao)落等原(yuan)因。此稱為虛(xu)焊現(xian)象。這種(zhong)情(qing)況只有(you)(you)叫專家修(xiu)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)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)一(yi)樣(yang)(yang)，輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不(bu)(bu)同(tong)，能不(bu)(bu)能用在(zai)同(tong)一(yi)臺本本上(shang)。基本的(de)(de)(de)(de)原則是(shi)(shi)大(da)(da)標(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)可以(yi)代(dai)替(ti)小(xiao)標(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)。估計(ji)有人會這樣(yang)(yang)想，覺得大(da)(da)標(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)會燒壞(huai)本本，因(yin)為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大(da)(da)了(le)嘛(ma)。實際上(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)多(duo)大(da)(da)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)相同(tong)的(de)(de)(de)(de)情況(kuang)下取(qu)決(jue)于負載(zai)，呵呵，想想初中的(de)(de)(de)(de)物理就(jiu)知道了(le)。當本本高負荷運轉的(de)(de)(de)(de)時(shi)候(hou)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大(da)(da)些(xie)(xie)，本本進入待(dai)機的(de)(de)(de)(de)時(shi)候(hou)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)就(jiu)小(xiao)些(xie)(xie)，大(da)(da)標(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)有足夠的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)余(yu)(yu)(yu)量。反之，有人用56w的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)代(dai)替(ti)72w的(de)(de)(de)(de)用起來(lai)也沒(mei)什么問題，原因(yin)是(shi)(shi)通常(chang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適配器的(de)(de)(de)(de)設計(ji)留有一(yi)定(ding)的(de)(de)(de)(de)余(yu)(yu)(yu)量，負載(zai)功率都要小(xiao)于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)功率，所以(yi)這種代(dai)替(ti)在(zai)一(yi)般使用上(shang)是(shi)(shi)可行的(de)(de)(de)(de)，但是(shi)(shi)剩余(yu)(yu)(yu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)功率余(yu)(yu)(yu)量就(jiu)很少了(le)，一(yi)旦(dan)你(ni)(ni)的(de)(de)(de)(de)本本接了(le)很多(duo)外(wai)設，比如兩塊usb硬盤，然(ran)后cpu全速運轉，再(zai)有一(yi)個底座，上(shang)面來(lai)個光驅全速讀盤，再(zai)加上(shang)同(tong)時(shi)給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，估計(ji)就(jiu)危險了(le)，要隨時(shi)用手(shou)摸摸你(ni)(ni)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)是(shi)(shi)不(bu)(bu)是(shi)(shi)已(yi)經可以(yi)煮(zhu)雞蛋了(le)。所以(yi)最好不(bu)(bu)要用小(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)代(dai)替(ti)大(da)(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(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)疑你的電源有問題，先(xian)看看你的本(ben)本(ben)在干什么，是不是像(xiang)上面(mian)說的兩(liang)塊USB硬(ying)盤，CPU全(quan)速(su)運轉(zhuan)，硬(ying)盤瘋狂(kuang)讀寫，光驅全(quan)速(su)讀盤，同時給電池充電，大聲放著音樂，屏幕亮(liang)度最(zui)大，無線網(wang)卡一直(zhi)在偵測信號等等，善用電源管理，根據任(ren)務合(he)理調(diao)整(zheng)本(ben)本(ben)的工作狀(zhuang)態是很重要的。

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，要知(zhi)道的是(shi)，電(dian)(dian)源給(gei)本(ben)本(ben)供電(dian)(dian)與電(dian)(dian)池給(gei)本(ben)本(ben)供電(dian)(dian)是(shi)不同(tong)的。

電(dian)(dian)(dian)池(chi)(chi)供(gong)電(dian)(dian)(dian)，電(dian)(dian)(dian)池(chi)(chi)的(de)輸出是純(chun)直(zhi)流(liu)，干凈(jing)得(de)(de)很(hen)，電(dian)(dian)(dian)池(chi)(chi)的(de)電(dian)(dian)(dian)壓既不可能也(ye)不需要設(she)計得(de)(de)很(hen)高(gao)，鋰電(dian)(dian)(dian)池(chi)(chi)的(de)化學(xue)特(te)性決定了(le)(le)(le)一(yi)節(jie)電(dian)(dian)(dian)芯的(de)輸出電(dian)(dian)(dian)壓只能在3。6V左右(you)，所以(yi)很(hen)多電(dian)(dian)(dian)池(chi)(chi)都(dou)是采用三級(ji)串聯的(de)方(fang)式，10。8V也(ye)就成了(le)(le)(le)很(hen)流(liu)行的(de)電(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)壓。有些電(dian)(dian)(dian)池(chi)(chi)的(de)標稱值比3。6V的(de)整數(shu)倍稍大一(yi)些，比如3。7V或者11。2V等(deng)等(deng)，其實是為了(le)(le)(le)保(bao)護電(dian)(dian)(dian)池(chi)(chi)。

電(dian)(dian)(dian)(dian)(dian)源(yuan)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)，情(qing)況就(jiu)復雜一些(xie)，首先需要對加(jia)入(ru)電(dian)(dian)(dian)(dian)(dian)壓進行進一步的(de)(de)(de)穩壓濾波，以(yi)保(bao)證在(zai)電(dian)(dian)(dian)(dian)(dian)源(yuan)性能不(bu)很好的(de)(de)(de)情(qing)況下穩定工作(zuo)，穩壓后的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓分成兩個部分，一路(lu)給(gei)本(ben)(ben)(ben)本(ben)(ben)(ben)工作(zuo)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)，另一路(lu)給(gei)電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)，給(gei)本(ben)(ben)(ben)本(ben)(ben)(ben)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)那(nei)部分同電(dian)(dian)(dian)(dian)(dian)池供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)時候相同，而給(gei)電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)那(nei)部分需要通(tong)過電(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)控制(zhi)電(dian)(dian)(dian)(dian)(dian)路(lu)才(cai)可以(yi)加(jia)在(zai)電(dian)(dian)(dian)(dian)(dian)芯上，控制(zhi)電(dian)(dian)(dian)(dian)(dian)路(lu)可以(yi)很復雜，所(suo)以(yi)電(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)壓必須大于電(dian)(dian)(dian)(dian)(dian)芯電(dian)(dian)(dian)(dian)(dian)壓才(cai)有充(chong)分的(de)(de)(de)能力(li)供(gong)(gong)應給(gei)充(chong)電(dian)(dian)(dian)(dian)(dian)控制(zhi)電(dian)(dian)(dian)(dian)(dian)路(lu)的(de)(de)(de)各單元。最后真(zhen)正加(jia)到電(dian)(dian)(dian)(dian)(dian)芯上的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓決不(bu)會是你的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)標稱(cheng)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓。
