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(liang)好，如不正常，嘗試重新安裝電(dian)源適配(pei)器或電(dian)池。可(ke)能出現的故障情況為(wei)電(dian)源接頭變形或電(dian)池觸(chu)點彈性下降。

第2步：如果電(dian)源或(huo)(huo)電(dian)池(chi)接(jie)頭良好，可用萬用表測電(dian)源適(shi)配器或(huo)(huo)電(dian)池(chi)的輸(shu)(shu)出(chu)電(dian)壓，主要查(cha)看輸(shu)(shu)出(chu)電(dian)壓是否穩定(ding)，以及(ji)實際輸(shu)(shu)出(chu)電(dian)壓值(zhi)與電(dian)源標稱電(dian)壓是否吻合，如果輸(shu)(shu)出(chu)不穩定(ding)或(huo)(huo)實際輸(shu)(shu)出(chu)電(dian)壓與產(chan)品標稱相差懸殊，則需更換損壞(huai)的電(dian)源適(shi)配器或(huo)(huo)電(dian)池(chi)。

第3步：如以上檢測步驟均顯示正常，則可推(tui)斷(duan)故障(zhang)在(zai)筆記(ji)本電(dian)源(yuan)板(ban)或主板(ban)上，此處需打開筆記(ji)本電(dian)腦外殼，并檢查電(dian)源(yuan)板(ban)與主板(ban)是否接觸良好。

第4步：如(ru)果電源板和(he)電池均接(jie)觸(chu)良好，則用DIY普(pu)遍使用的替換(huan)法檢查電源板是否正常，如(ru)不正常，更換(huan)即可。

第5步：如通過以上方(fang)法確認電源(yuan)板(ban)(ban)、電池均正常，則可(ke)推(tui)斷是筆記本主板(ban)(ban)或(huo)其他主部(bu)件損壞（如開(kai)機電路故障），此時可(ke)維修或(huo)更換主板(ban)(ban)。

二、電源適配器壞了怎么辦

1、檢查電源適配器(qi)指標燈，如果(guo)指示燈亮，一般認為從電源到適配器(qi)之間(jian)沒有問題，必須保(bao)證是指示燈本身沒壞(huai)。

2、檢查電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)配(pei)器到電(dian)(dian)(dian)(dian)腦(nao)之(zhi)間的(de)(de)有沒(mei)有電(dian)(dian)(dian)(dian)。這個可以通過(guo)筆記(ji)本(ben)的(de)(de)指示燈顯示，有電(dian)(dian)(dian)(dian)源(yuan)充(chong)到筆記(ji)本(ben)的(de)(de)時(shi)候，那個充(chong)電(dian)(dian)(dian)(dian)指示燈會(hui)亮。否則(ze)，不(bu)會(hui)亮。或者找一個同品牌(pai)的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)配(pei)器交換試試。用你的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)配(pei)器手對方(fang)筆記(ji)本(ben)，如果對方(fang)電(dian)(dian)(dian)(dian)腦(nao)工作正(zheng)常，則(ze)你的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)配(pei)器沒(mei)問題。否則(ze)，可能你的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)配(pei)器有問題。如果對方(fang)的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)配(pei)器插你電(dian)(dian)(dian)(dian)腦(nao)上后，你的(de)(de)電(dian)(dian)(dian)(dian)腦(nao)工作正(zheng)常，而用自己的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)配(pei)器卻不(bu)能正(zheng)常工作，那么(me)你的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)(shi)配(pei)器有問題。

3、觀測電(dian)腦(nao)的指(zhi)示(shi)燈變化。如果(guo)你(ni)插上電(dian)源適(shi)配(pei)器后，你(ni)可以看(kan)到充電(dian)的指(zhi)示(shi)燈時(shi)(shi)亮時(shi)(shi)滅，有(you)(you)時(shi)(shi)間一直不滅，則是筆記本里(li)(li)面那(nei)個電(dian)源適(shi)配(pei)器接(jie)口有(you)(you)問(wen)題，一般可能里(li)(li)面線斷了，電(dian)路板老(lao)化，焊接(jie)掉落等原因。此稱(cheng)為虛(xu)焊現象。這(zhe)種情(qing)況只有(you)(you)叫(jiao)專家(jia)修理了。

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)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓一樣(yang)，輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)不(bu)同(tong)，能(neng)不(bu)能(neng)用(yong)在同(tong)一臺本(ben)(ben)(ben)本(ben)(ben)(ben)上。基本(ben)(ben)(ben)的(de)(de)(de)原(yuan)則是(shi)(shi)大(da)(da)標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)可以(yi)代(dai)替小(xiao)標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)。估計有(you)人(ren)(ren)會(hui)這(zhe)樣(yang)想，覺(jue)得大(da)(da)標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)會(hui)燒壞本(ben)(ben)(ben)本(ben)(ben)(ben)，因為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)大(da)(da)了(le)嘛。實際(ji)上電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)多大(da)(da)在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓相同(tong)的(de)(de)(de)情況下取(qu)決于(yu)負載，呵呵，想想初中(zhong)的(de)(de)(de)物理(li)就知道了(le)。當本(ben)(ben)(ben)本(ben)(ben)(ben)高(gao)負荷運(yun)轉的(de)(de)(de)時(shi)(shi)候，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)大(da)(da)些，本(ben)(ben)(ben)本(ben)(ben)(ben)進(jin)入待機的(de)(de)(de)時(shi)(shi)候，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)就小(xiao)些，大(da)(da)標(biao)稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)有(you)足夠的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)余(yu)量(liang)。反之，有(you)人(ren)(ren)用(yong)56w的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)代(dai)替72w的(de)(de)(de)用(yong)起來也沒什么問題(ti)，原(yuan)因是(shi)(shi)通(tong)常電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適配器的(de)(de)(de)設計留有(you)一定的(de)(de)(de)余(yu)量(liang)，負載功(gong)率都要(yao)(yao)小(xiao)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)功(gong)率，所(suo)以(yi)這(zhe)種代(dai)替在一般使用(yong)上是(shi)(shi)可行的(de)(de)(de)，但是(shi)(shi)剩余(yu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)功(gong)率余(yu)量(liang)就很少了(le)，一旦你(ni)的(de)(de)(de)本(ben)(ben)(ben)本(ben)(ben)(ben)接了(le)很多外設，比如兩塊usb硬盤，然后cpu全速運(yun)轉，再(zai)有(you)一個底座，上面來個光(guang)驅全速讀盤，再(zai)加上同(tong)時(shi)(shi)給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，估計就危險了(le)，要(yao)(yao)隨(sui)時(shi)(shi)用(yong)手摸(mo)摸(mo)你(ni)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)是(shi)(shi)不(bu)是(shi)(shi)已經可以(yi)煮雞蛋了(le)。所(suo)以(yi)最好(hao)不(bu)要(yao)(yao)用(yong)小(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)代(dai)替大(da)(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)電(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(bu)要懷疑你的電源(yuan)有問(wen)題，先(xian)看看你的本本在干什么，是(shi)不(bu)是(shi)像上面說(shuo)的兩塊(kuai)USB硬盤(pan)，CPU全(quan)速運(yun)轉(zhuan)，硬盤(pan)瘋狂(kuang)讀(du)寫，光驅全(quan)速讀(du)盤(pan)，同(tong)時給電池充電，大聲放著音樂，屏幕亮(liang)度最大，無線(xian)網卡一(yi)直(zhi)在偵測信號等(deng)等(deng)，善(shan)用電源(yuan)管理(li)，根據(ju)任務合理(li)調(diao)整本本的工(gong)作狀態(tai)是(shi)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(yao)知(zhi)道的(de)是，電源給本(ben)(ben)本(ben)(ben)供電與電池(chi)給本(ben)(ben)本(ben)(ben)供電是不同的(de)。

電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)供(gong)電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的輸(shu)出是(shi)純(chun)直流，干凈得很(hen)，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的電(dian)(dian)(dian)(dian)壓(ya)(ya)既不可能也不需要設計得很(hen)高，鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的化學特性決定了一節電(dian)(dian)(dian)(dian)芯(xin)的輸(shu)出電(dian)(dian)(dian)(dian)壓(ya)(ya)只能在(zai)3。6V左右，所以(yi)很(hen)多電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)都(dou)是(shi)采用三級串(chuan)聯的方(fang)式，10。8V也就成了很(hen)流行的電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)(dian)壓(ya)(ya)。有些(xie)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的標稱值比3。6V的整數倍(bei)稍大一些(xie)，比如3。7V或者11。2V等等，其實是(shi)為了保(bao)護電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。

電(dian)(dian)(dian)(dian)源供(gong)電(dian)(dian)(dian)(dian)，情況(kuang)就復(fu)雜一(yi)些(xie)，首先需(xu)要對加(jia)入電(dian)(dian)(dian)(dian)壓(ya)(ya)進(jin)(jin)行進(jin)(jin)一(yi)步的(de)穩壓(ya)(ya)濾波，以保證在電(dian)(dian)(dian)(dian)源性能不(bu)很(hen)(hen)好的(de)情況(kuang)下穩定工(gong)作，穩壓(ya)(ya)后(hou)的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)分(fen)成兩個部分(fen)，一(yi)路(lu)給(gei)本本工(gong)作供(gong)電(dian)(dian)(dian)(dian)，另一(yi)路(lu)給(gei)電(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)，給(gei)本本供(gong)電(dian)(dian)(dian)(dian)的(de)那部分(fen)同(tong)電(dian)(dian)(dian)(dian)池(chi)供(gong)電(dian)(dian)(dian)(dian)的(de)時候相同(tong)，而給(gei)電(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)的(de)那部分(fen)需(xu)要通過電(dian)(dian)(dian)(dian)池(chi)的(de)充電(dian)(dian)(dian)(dian)控制電(dian)(dian)(dian)(dian)路(lu)才可(ke)以加(jia)在電(dian)(dian)(dian)(dian)芯(xin)上(shang)，控制電(dian)(dian)(dian)(dian)路(lu)可(ke)以很(hen)(hen)復(fu)雜，所以電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)(ya)必須大于(yu)電(dian)(dian)(dian)(dian)芯(xin)電(dian)(dian)(dian)(dian)壓(ya)(ya)才有充分(fen)的(de)能力供(gong)應給(gei)充電(dian)(dian)(dian)(dian)控制電(dian)(dian)(dian)(dian)路(lu)的(de)各單(dan)元(yuan)。最(zui)后(hou)真正加(jia)到電(dian)(dian)(dian)(dian)芯(xin)上(shang)的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)決(jue)不(bu)會是(shi)你(ni)的(de)電(dian)(dian)(dian)(dian)源標稱的(de)電(dian)(dian)(dian)(dian)壓(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(yi)及筆(bi)記本(ben)電源適(shi)配(pei)器壞(huai)了怎么修的(de)(de)相(xiang)關(guan)內容(rong)，筆(bi)記本(ben)電腦電源適(shi)配(pei)器是我們工作生活(huo)中都比較(jiao)常用(yong)的(de)(de)，所以(yi)了解相(xiang)關(guan)知識(shi)，更有(you)利于(yu)安全便(bian)捷的(de)(de)使用(yong)電源適(shi)配(pei)器。
