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)池是否接(jie)(jie)觸良(liang)好，如不正常，嘗試重新安裝電(dian)(dian)源(yuan)適(shi)配器或(huo)電(dian)(dian)池。可(ke)能出(chu)現(xian)的故障情況為(wei)電(dian)(dian)源(yuan)接(jie)(jie)頭變形(xing)或(huo)電(dian)(dian)池觸點(dian)彈(dan)性下降。

第2步：如果(guo)電(dian)源(yuan)(yuan)或(huo)(huo)電(dian)池接頭良好，可用(yong)萬(wan)用(yong)表測電(dian)源(yuan)(yuan)適配器(qi)或(huo)(huo)電(dian)池的(de)輸(shu)出(chu)電(dian)壓(ya)，主(zhu)要查看輸(shu)出(chu)電(dian)壓(ya)是否穩定，以及實際輸(shu)出(chu)電(dian)壓(ya)值與(yu)電(dian)源(yuan)(yuan)標稱電(dian)壓(ya)是否吻合，如果(guo)輸(shu)出(chu)不穩定或(huo)(huo)實際輸(shu)出(chu)電(dian)壓(ya)與(yu)產品標稱相差懸殊，則需更換(huan)損壞的(de)電(dian)源(yuan)(yuan)適配器(qi)或(huo)(huo)電(dian)池。

第3步：如以上(shang)檢(jian)測(ce)步驟(zou)均顯示正常(chang)，則可推斷故(gu)障在筆(bi)記本(ben)電(dian)源板(ban)(ban)或主(zhu)板(ban)(ban)上(shang)，此處需打開筆(bi)記本(ben)電(dian)腦外殼(ke)，并檢(jian)查電(dian)源板(ban)(ban)與主(zhu)板(ban)(ban)是否接觸良好。

第4步(bu)：如(ru)果電(dian)源板(ban)和電(dian)池均接觸良好，則(ze)用(yong)DIY普遍使用(yong)的替換法檢查電(dian)源板(ban)是(shi)否正常，如(ru)不正常，更換即可。

第5步：如通過以上(shang)方法確認(ren)電(dian)(dian)源板(ban)、電(dian)(dian)池均正常(chang)，則可推(tui)斷是筆記(ji)本主(zhu)(zhu)板(ban)或(huo)其(qi)他主(zhu)(zhu)部(bu)件損壞（如開機(ji)電(dian)(dian)路故障），此時可維修或(huo)更換(huan)主(zhu)(zhu)板(ban)。

二、電源適配器壞了怎么辦

1、檢查電(dian)源適配器(qi)指標燈，如果指示(shi)燈亮，一般認為(wei)從(cong)電(dian)源到適配器(qi)之間沒有問題，必須(xu)保(bao)證(zheng)是指示(shi)燈本身沒壞。

2、檢查電(dian)(dian)(dian)源適(shi)配(pei)(pei)(pei)(pei)器(qi)到(dao)電(dian)(dian)(dian)腦之間(jian)的(de)(de)有沒(mei)有電(dian)(dian)(dian)。這個(ge)可以通過筆記(ji)(ji)本的(de)(de)指示(shi)燈(deng)顯示(shi)，有電(dian)(dian)(dian)源充到(dao)筆記(ji)(ji)本的(de)(de)時候，那個(ge)充電(dian)(dian)(dian)指示(shi)燈(deng)會亮。否(fou)則，不(bu)會亮。或者找(zhao)一個(ge)同品牌的(de)(de)電(dian)(dian)(dian)源適(shi)配(pei)(pei)(pei)(pei)器(qi)交換試試。用(yong)(yong)你(ni)的(de)(de)電(dian)(dian)(dian)源適(shi)配(pei)(pei)(pei)(pei)器(qi)手(shou)對方筆記(ji)(ji)本，如(ru)果對方電(dian)(dian)(dian)腦工(gong)作正常，則你(ni)的(de)(de)電(dian)(dian)(dian)源適(shi)配(pei)(pei)(pei)(pei)器(qi)沒(mei)問題。否(fou)則，可能(neng)(neng)你(ni)的(de)(de)電(dian)(dian)(dian)源適(shi)配(pei)(pei)(pei)(pei)器(qi)有問題。如(ru)果對方的(de)(de)電(dian)(dian)(dian)源適(shi)配(pei)(pei)(pei)(pei)器(qi)插你(ni)電(dian)(dian)(dian)腦上后，你(ni)的(de)(de)電(dian)(dian)(dian)腦工(gong)作正常，而用(yong)(yong)自己(ji)的(de)(de)電(dian)(dian)(dian)源適(shi)配(pei)(pei)(pei)(pei)器(qi)卻不(bu)能(neng)(neng)正常工(gong)作，那么(me)你(ni)的(de)(de)電(dian)(dian)(dian)源適(shi)配(pei)(pei)(pei)(pei)器(qi)有問題。

3、觀測電(dian)腦的指示燈變化(hua)(hua)。如果你插上電(dian)源適配器(qi)后，你可以(yi)看到充電(dian)的指示燈時(shi)亮(liang)時(shi)滅，有(you)時(shi)間一直不(bu)滅，則是筆記本里面那個電(dian)源適配器(qi)接口有(you)問(wen)題，一般可能里面線斷了(le)，電(dian)路板老化(hua)(hua)，焊接掉落(luo)等(deng)原(yuan)因。此稱(cheng)為(wei)虛焊現象。這種情況(kuang)只有(you)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)(dian)(dian)源(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)一(yi)(yi)(yi)樣，輸出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流不同(tong)(tong)，能(neng)不能(neng)用(yong)在(zai)同(tong)(tong)一(yi)(yi)(yi)臺本(ben)(ben)(ben)(ben)本(ben)(ben)(ben)(ben)上(shang)。基(ji)本(ben)(ben)(ben)(ben)的(de)(de)(de)(de)(de)原(yuan)則是(shi)(shi)(shi)(shi)大(da)標稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)可以(yi)代替(ti)小標稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)。估計有(you)(you)人會這樣想(xiang)，覺得大(da)標稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)會燒壞本(ben)(ben)(ben)(ben)本(ben)(ben)(ben)(ben)，因(yin)(yin)為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流大(da)了(le)嘛。實際上(shang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流多大(da)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)相(xiang)同(tong)(tong)的(de)(de)(de)(de)(de)情況下取決于(yu)負(fu)載(zai)，呵呵，想(xiang)想(xiang)初中(zhong)的(de)(de)(de)(de)(de)物理就(jiu)知道了(le)。當本(ben)(ben)(ben)(ben)本(ben)(ben)(ben)(ben)高負(fu)荷運轉的(de)(de)(de)(de)(de)時候，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流大(da)些(xie)，本(ben)(ben)(ben)(ben)本(ben)(ben)(ben)(ben)進入待機的(de)(de)(de)(de)(de)時候，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流就(jiu)小些(xie)，大(da)標稱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)有(you)(you)足夠的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流余量(liang)。反(fan)之，有(you)(you)人用(yong)56w的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)代替(ti)72w的(de)(de)(de)(de)(de)用(yong)起(qi)來也沒(mei)什么問題，原(yuan)因(yin)(yin)是(shi)(shi)(shi)(shi)通常電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適配器的(de)(de)(de)(de)(de)設(she)計留有(you)(you)一(yi)(yi)(yi)定的(de)(de)(de)(de)(de)余量(liang)，負(fu)載(zai)功(gong)率(lv)都要(yao)小于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)功(gong)率(lv)，所以(yi)這種(zhong)代替(ti)在(zai)一(yi)(yi)(yi)般使用(yong)上(shang)是(shi)(shi)(shi)(shi)可行的(de)(de)(de)(de)(de)，但是(shi)(shi)(shi)(shi)剩余的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)功(gong)率(lv)余量(liang)就(jiu)很(hen)(hen)少了(le)，一(yi)(yi)(yi)旦你的(de)(de)(de)(de)(de)本(ben)(ben)(ben)(ben)本(ben)(ben)(ben)(ben)接了(le)很(hen)(hen)多外設(she)，比如兩塊usb硬(ying)盤(pan)，然(ran)后cpu全速運轉，再(zai)有(you)(you)一(yi)(yi)(yi)個(ge)底座，上(shang)面來個(ge)光驅全速讀盤(pan)，再(zai)加(jia)上(shang)同(tong)(tong)時給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，估計就(jiu)危(wei)險了(le)，要(yao)隨(sui)時用(yong)手摸(mo)摸(mo)你的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)是(shi)(shi)(shi)(shi)不是(shi)(shi)(shi)(shi)已經可以(yi)煮雞蛋了(le)。所以(yi)最好不要(yao)用(yong)小電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)代替(ti)大(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流電(dian)(dian)(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？

先不要懷疑你(ni)的(de)(de)電(dian)(dian)源有問(wen)題，先看看你(ni)的(de)(de)本(ben)本(ben)在(zai)干什么，是不是像上(shang)面(mian)說的(de)(de)兩塊USB硬盤，CPU全(quan)速運轉，硬盤瘋狂讀寫，光驅(qu)全(quan)速讀盤，同時給電(dian)(dian)池充(chong)電(dian)(dian)，大(da)聲放著音樂，屏幕亮度最大(da)，無線(xian)網卡一直在(zai)偵(zhen)測信號(hao)等等，善用(yong)電(dian)(dian)源管理，根據(ju)任務(wu)合(he)理調整(zheng)本(ben)本(ben)的(de)(de)工作狀態是很重要的(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(yao)知道的(de)是，電(dian)源給(gei)本本供電(dian)與電(dian)池(chi)給(gei)本本供電(dian)是不同(tong)的(de)。

電(dian)(dian)池(chi)供電(dian)(dian)，電(dian)(dian)池(chi)的(de)(de)輸出是純(chun)直流，干凈得很(hen)(hen)，電(dian)(dian)池(chi)的(de)(de)電(dian)(dian)壓既(ji)不可能也(ye)不需要設計得很(hen)(hen)高(gao)，鋰(li)電(dian)(dian)池(chi)的(de)(de)化學特性決定了一節(jie)電(dian)(dian)芯的(de)(de)輸出電(dian)(dian)壓只能在3。6V左右，所(suo)以很(hen)(hen)多電(dian)(dian)池(chi)都是采用三(san)級串聯的(de)(de)方式，10。8V也(ye)就成了很(hen)(hen)流行的(de)(de)電(dian)(dian)池(chi)電(dian)(dian)壓。有(you)些(xie)電(dian)(dian)池(chi)的(de)(de)標(biao)稱(cheng)值(zhi)比3。6V的(de)(de)整數倍稍大一些(xie)，比如3。7V或者11。2V等等，其實是為了保護電(dian)(dian)池(chi)。

電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)，情況就復雜一(yi)些，首(shou)先需(xu)(xu)要(yao)對加(jia)入電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)進行進一(yi)步的(de)(de)穩(wen)壓(ya)濾波，以保證在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)性能(neng)不很好的(de)(de)情況下穩(wen)定工作，穩(wen)壓(ya)后的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)分(fen)成兩個部(bu)分(fen)，一(yi)路(lu)給(gei)(gei)本本工作供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)，另一(yi)路(lu)給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)，給(gei)(gei)本本供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)那(nei)部(bu)分(fen)同電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)時候相同，而(er)給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)那(nei)部(bu)分(fen)需(xu)(xu)要(yao)通過電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)充電(dian)(dian)(dian)(dian)(dian)(dian)控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)才可以加(jia)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)芯上，控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)可以很復雜，所以電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)必須大于電(dian)(dian)(dian)(dian)(dian)(dian)芯電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)才有充分(fen)的(de)(de)能(neng)力供(gong)應(ying)給(gei)(gei)充電(dian)(dian)(dian)(dian)(dian)(dian)控(kong)(kong)制(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)的(de)(de)各(ge)單元。最(zui)后真正加(jia)到電(dian)(dian)(dian)(dian)(dian)(dian)芯上的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)決不會是你的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)標(biao)稱的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)。
