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池(chi)(chi)是否接(jie)觸良好，如不正常，嘗試重新安(an)裝電源適配器(qi)或電池(chi)(chi)。可能(neng)出現的故障情況為電源接(jie)頭變形或電池(chi)(chi)觸點彈性下降。

第2步(bu)：如果電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)或(huo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池接頭良好，可用萬用表測電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適配器或(huo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)輸出(chu)(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，主要查看輸出(chu)(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)是否穩定(ding)，以及實(shi)際輸出(chu)(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)值與(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)標(biao)稱(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)是否吻合，如果輸出(chu)(chu)不穩定(ding)或(huo)實(shi)際輸出(chu)(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)與(yu)產品(pin)標(biao)稱(cheng)相差懸殊，則(ze)需更(geng)換損壞的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適配器或(huo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池。

第3步(bu)(bu)：如以上檢(jian)測步(bu)(bu)驟(zou)均顯示正常，則可推斷故(gu)障在筆(bi)記本電源(yuan)板(ban)或(huo)主板(ban)上，此處需(xu)打開筆(bi)記本電腦外(wai)殼(ke)，并檢(jian)查電源(yuan)板(ban)與(yu)主板(ban)是否接(jie)觸(chu)良好(hao)。

第(di)4步：如果電源(yuan)板和(he)電池均接觸良(liang)好，則用DIY普遍(bian)使用的替換法檢(jian)查(cha)電源(yuan)板是(shi)否正(zheng)常，如不正(zheng)常，更換即可。

第5步：如通(tong)過以上方法確認(ren)電(dian)(dian)源板、電(dian)(dian)池均正常(chang)，則可推斷是筆記本主(zhu)板或其他主(zhu)部(bu)件損(sun)壞（如開機電(dian)(dian)路故障），此時(shi)可維(wei)修或更(geng)換主(zhu)板。

二、電源適配器壞了怎么辦

1、檢查電源適配器指標燈(deng)，如(ru)果指示(shi)燈(deng)亮(liang)，一般認(ren)為從(cong)電源到適配器之間(jian)沒(mei)有問題，必須保(bao)證是指示(shi)燈(deng)本身沒(mei)壞。

2、檢查(cha)電(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)配器(qi)到電(dian)(dian)(dian)腦(nao)之間的(de)(de)(de)(de)有(you)沒(mei)有(you)電(dian)(dian)(dian)。這(zhe)個可(ke)(ke)以通過筆記(ji)本的(de)(de)(de)(de)指(zhi)示(shi)燈(deng)(deng)顯示(shi)，有(you)電(dian)(dian)(dian)源(yuan)充(chong)到筆記(ji)本的(de)(de)(de)(de)時(shi)候，那(nei)個充(chong)電(dian)(dian)(dian)指(zhi)示(shi)燈(deng)(deng)會(hui)亮(liang)。否則(ze)，不會(hui)亮(liang)。或者找一(yi)個同品(pin)牌的(de)(de)(de)(de)電(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)配器(qi)交換試(shi)試(shi)。用你(ni)的(de)(de)(de)(de)電(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)配器(qi)手對方筆記(ji)本，如(ru)果(guo)對方電(dian)(dian)(dian)腦(nao)工(gong)作(zuo)正常，則(ze)你(ni)的(de)(de)(de)(de)電(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)配器(qi)沒(mei)問題(ti)。否則(ze)，可(ke)(ke)能你(ni)的(de)(de)(de)(de)電(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)配器(qi)有(you)問題(ti)。如(ru)果(guo)對方的(de)(de)(de)(de)電(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)配器(qi)插(cha)你(ni)電(dian)(dian)(dian)腦(nao)上后，你(ni)的(de)(de)(de)(de)電(dian)(dian)(dian)腦(nao)工(gong)作(zuo)正常，而用自己的(de)(de)(de)(de)電(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)配器(qi)卻(que)不能正常工(gong)作(zuo)，那(nei)么你(ni)的(de)(de)(de)(de)電(dian)(dian)(dian)源(yuan)適(shi)(shi)(shi)配器(qi)有(you)問題(ti)。

3、觀測(ce)電腦的指(zhi)示(shi)燈變化。如果你(ni)插上電源適(shi)配(pei)器(qi)后，你(ni)可(ke)以(yi)看到(dao)充(chong)電的指(zhi)示(shi)燈時亮時滅(mie)，有(you)時間一直不滅(mie)，則是筆記(ji)本(ben)里面那個電源適(shi)配(pei)器(qi)接(jie)口有(you)問題，一般可(ke)能里面線斷(duan)了，電路板老(lao)化，焊接(jie)掉落等原(yuan)因。此稱為虛焊現象。這(zhe)種情(qing)況(kuang)只有(you)叫專家(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)源(yuan)(yuan)(yuan)(yuan)(yuan)電(dian)(dian)(dian)(dian)壓一(yi)樣(yang)，輸出電(dian)(dian)(dian)(dian)流(liu)(liu)不(bu)同，能不(bu)能用(yong)(yong)在同一(yi)臺本(ben)(ben)本(ben)(ben)上。基(ji)本(ben)(ben)的(de)(de)(de)(de)原則(ze)是大標稱電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)可以(yi)代替(ti)小(xiao)(xiao)標稱電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)。估(gu)計(ji)有(you)(you)人(ren)(ren)會(hui)這(zhe)樣(yang)想，覺得大標稱電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)會(hui)燒壞本(ben)(ben)本(ben)(ben)，因為電(dian)(dian)(dian)(dian)流(liu)(liu)大了(le)嘛(ma)。實(shi)際上電(dian)(dian)(dian)(dian)流(liu)(liu)多大在電(dian)(dian)(dian)(dian)壓相同的(de)(de)(de)(de)情況下取決于負(fu)載，呵呵，想想初中的(de)(de)(de)(de)物(wu)理就(jiu)知道了(le)。當本(ben)(ben)本(ben)(ben)高負(fu)荷運(yun)轉的(de)(de)(de)(de)時(shi)候(hou)，電(dian)(dian)(dian)(dian)流(liu)(liu)大些，本(ben)(ben)本(ben)(ben)進入待機的(de)(de)(de)(de)時(shi)候(hou)，電(dian)(dian)(dian)(dian)流(liu)(liu)就(jiu)小(xiao)(xiao)些，大標稱電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)有(you)(you)足夠的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)余(yu)量。反之(zhi)，有(you)(you)人(ren)(ren)用(yong)(yong)56w的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)代替(ti)72w的(de)(de)(de)(de)用(yong)(yong)起來(lai)也沒什么(me)問題(ti)，原因是通(tong)常電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)適配器的(de)(de)(de)(de)設計(ji)留有(you)(you)一(yi)定(ding)的(de)(de)(de)(de)余(yu)量，負(fu)載功率(lv)都要小(xiao)(xiao)于電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)功率(lv)，所以(yi)這(zhe)種(zhong)代替(ti)在一(yi)般使用(yong)(yong)上是可行的(de)(de)(de)(de)，但是剩余(yu)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)功率(lv)余(yu)量就(jiu)很(hen)少了(le)，一(yi)旦你的(de)(de)(de)(de)本(ben)(ben)本(ben)(ben)接了(le)很(hen)多外設，比(bi)如兩塊usb硬盤(pan)，然后cpu全速(su)運(yun)轉，再有(you)(you)一(yi)個底座，上面來(lai)個光驅(qu)全速(su)讀盤(pan)，再加上同時(shi)給電(dian)(dian)(dian)(dian)池充電(dian)(dian)(dian)(dian)，估(gu)計(ji)就(jiu)危險了(le)，要隨時(shi)用(yong)(yong)手摸摸你的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)是不(bu)是已(yi)經可以(yi)煮雞(ji)蛋了(le)。所以(yi)最(zui)好不(bu)要用(yong)(yong)小(xiao)(xiao)電(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)(yuan)代替(ti)大電(dian)(dian)(dian)(dian)流(liu)(liu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(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)的電(dian)源(yuan)有問題，先看(kan)看(kan)你(ni)的本(ben)(ben)本(ben)(ben)在干(gan)什么(me)，是(shi)(shi)不是(shi)(shi)像上面說的兩塊(kuai)USB硬(ying)(ying)盤，CPU全(quan)速運轉，硬(ying)(ying)盤瘋狂讀(du)寫(xie)，光驅(qu)全(quan)速讀(du)盤，同時給電(dian)池(chi)充電(dian)，大聲(sheng)放著音樂，屏幕亮度最大，無線網(wang)卡一直在偵測(ce)信號等(deng)等(deng)，善用電(dian)源(yuan)管理(li)，根據任務合理(li)調整本(ben)(ben)本(ben)(ben)的工作狀態是(shi)(shi)很重(zhong)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，要知道(dao)的(de)是，電源給(gei)本(ben)本(ben)供電與電池(chi)給(gei)本(ben)本(ben)供電是不(bu)同的(de)。

電(dian)(dian)池(chi)(chi)(chi)供電(dian)(dian)，電(dian)(dian)池(chi)(chi)(chi)的輸出是純直流(liu)，干凈得很(hen)(hen)，電(dian)(dian)池(chi)(chi)(chi)的電(dian)(dian)壓(ya)既不可(ke)能也不需要設計得很(hen)(hen)高(gao)，鋰電(dian)(dian)池(chi)(chi)(chi)的化學(xue)特(te)性決定(ding)了(le)一節電(dian)(dian)芯的輸出電(dian)(dian)壓(ya)只能在3。6V左右，所(suo)以很(hen)(hen)多電(dian)(dian)池(chi)(chi)(chi)都(dou)是采用三級串聯的方式，10。8V也就成了(le)很(hen)(hen)流(liu)行的電(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)壓(ya)。有(you)些(xie)電(dian)(dian)池(chi)(chi)(chi)的標稱值比3。6V的整數倍稍大一些(xie)，比如3。7V或者11。2V等(deng)等(deng)，其實(shi)是為了(le)保護電(dian)(dian)池(chi)(chi)(chi)。

電(dian)(dian)(dian)源供(gong)(gong)電(dian)(dian)(dian)，情況就(jiu)復雜(za)一些(xie)，首先(xian)需(xu)要對(dui)加(jia)入電(dian)(dian)(dian)壓(ya)進行進一步的(de)(de)(de)穩(wen)壓(ya)濾波，以(yi)保證(zheng)在(zai)電(dian)(dian)(dian)源性能不(bu)很好的(de)(de)(de)情況下穩(wen)定工作，穩(wen)壓(ya)后(hou)的(de)(de)(de)電(dian)(dian)(dian)壓(ya)分成兩個部分，一路(lu)(lu)給(gei)(gei)本本工作供(gong)(gong)電(dian)(dian)(dian)，另一路(lu)(lu)給(gei)(gei)電(dian)(dian)(dian)池充電(dian)(dian)(dian)，給(gei)(gei)本本供(gong)(gong)電(dian)(dian)(dian)的(de)(de)(de)那部分同電(dian)(dian)(dian)池供(gong)(gong)電(dian)(dian)(dian)的(de)(de)(de)時(shi)候相同，而給(gei)(gei)電(dian)(dian)(dian)池充電(dian)(dian)(dian)的(de)(de)(de)那部分需(xu)要通過電(dian)(dian)(dian)池的(de)(de)(de)充電(dian)(dian)(dian)控(kong)制電(dian)(dian)(dian)路(lu)(lu)才(cai)可以(yi)加(jia)在(zai)電(dian)(dian)(dian)芯上(shang)，控(kong)制電(dian)(dian)(dian)路(lu)(lu)可以(yi)很復雜(za)，所以(yi)電(dian)(dian)(dian)源電(dian)(dian)(dian)壓(ya)必須(xu)大于電(dian)(dian)(dian)芯電(dian)(dian)(dian)壓(ya)才(cai)有充分的(de)(de)(de)能力(li)供(gong)(gong)應給(gei)(gei)充電(dian)(dian)(dian)控(kong)制電(dian)(dian)(dian)路(lu)(lu)的(de)(de)(de)各單元。最(zui)后(hou)真正加(jia)到電(dian)(dian)(dian)芯上(shang)的(de)(de)(de)電(dian)(dian)(dian)壓(ya)決不(bu)會是你的(de)(de)(de)電(dian)(dian)(dian)源標稱的(de)(de)(de)電(dian)(dian)(dian)壓(ya)。
