【筆(bi)記本(ben)電池(chi)】筆記本電池充不進電的原因 筆記本電池不充電怎么辦

一：電源適配器故障

電源適(shi)配(pei)器有很多朋友稱之為充(chong)(chong)(chong)電(dian)(dian)器，雖然不(bu)夠準(zhun)確，但也(ye)(ye)確實很形象(xiang)。判斷是(shi)不(bu)是(shi)由(you)于電(dian)(dian)源引(yin)起(qi)的(de)不(bu)充(chong)(chong)(chong)電(dian)(dian)也(ye)(ye)很簡(jian)單，替(ti)換法就(jiu)可以。這種故(gu)(gu)障(zhang)在DELL筆記本維修中(zhong)多見(jian)，DELL筆記本采(cai)(cai)用(yong)LBK（DELL架構），充(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)路(lu)設計比(bi)較特別，適(shi)配(pei)器如(ru)果(guo)出現問題(ti)會(hui)不(bu)充(chong)(chong)(chong)電(dian)(dian)，如(ru)果(guo)不(bu)是(shi)原裝的(de)適(shi)配(pei)器也(ye)(ye)會(hui)出現不(bu)充(chong)(chong)(chong)電(dian)(dian)的(de)問題(ti)。在HP稍新一些的(de)筆記本中(zhong)也(ye)(ye)有較多的(de)機型采(cai)(cai)用(yong)了這種充(chong)(chong)(chong)電(dian)(dian)電(dian)(dian)路(lu)，比(bi)較經典故(gu)(gu)障(zhang)的(de)是(shi)HP NX6400 CPU占用(yong)率百分百也(ye)(ye)是(shi)由(you)于電(dian)(dian)源故(gu)(gu)障(zhang)引(yin)起(qi)的(de)。

二：電池故障

筆(bi)記本電(dian)池(chi)(chi)故(gu)障表(biao)現比較簡(jian)單(dan)，多是(shi)充電(dian)進度(du)一(yi)直(zhi)顯示100%，實際上(shang)一(yi)去(qu)掉電(dian)源適配(pei)(pei)器(qi)續航時間不到幾分鐘，或是(shi)直(zhi)接檢測不到電(dian)池(chi)(chi)。主要是(shi)由于電(dian)池(chi)(chi)本身的正常損耗，筆(bi)記本電(dian)池(chi)(chi)、光驅、風(feng)扇這三樣在筆(bi)記本配(pei)(pei)件算的上(shang)是(shi)名符其實的“耗材”了(le)。

相(xiang)關提示：筆(bi)記本電(dian)(dian)(dian)(dian)(dian)(dian)腦即(ji)便是(shi)在(zai)關閉電(dian)(dian)(dian)(dian)(dian)(dian)源時，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)也始終處于(yu)耗電(dian)(dian)(dian)(dian)(dian)(dian)狀(zhuang)態，用來(lai)維持主板上(shang)的基本待機電(dian)(dian)(dian)(dian)(dian)(dian)壓。一旦連上(shang)外(wai)接電(dian)(dian)(dian)(dian)(dian)(dian)源，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)便會在(zai)默(mo)認情況下自動(dong)開始充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)。有(you)許多筆(bi)記本是(shi)放(fang)(fang)在(zai)辦公室或家(jia)里不(bu)常移動(dong)的，但由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)長(chang)期裝在(zai)機器上(shang)，始終循環充(chong)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)，也嚴重(zhong)影響了電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的使用壽命。有(you)的人說自己的筆(bi)記本電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)幾乎(hu)沒單獨使用過(guo)幾次就不(bu)能用了，就是(shi)這(zhe)個原因(yin)。所(suo)以筆(bi)記本長(chang)時間不(bu)用的話(hua)一定要把電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)取(qu)下來(lai)，將其電(dian)(dian)(dian)(dian)(dian)(dian)量控制在(zai)40%，并存儲在(zai)15℃甚(shen)至(zhi)更低的溫度下即(ji)可。

故障的(de)判(pan)斷也是(shi)(shi)(shi)用替(ti)換(huan)法，有(you)時不(bu)(bu)能找到相同型號的(de)電(dian)池(chi)就(jiu)(jiu)(jiu)需(xu)要到專業的(de)筆記(ji)本(ben)(ben)維(wei)修(xiu)(xiu)中(zhong)心尋(xun)求幫助(zhu)了(le)。以(yi)前在我們的(de)維(wei)修(xiu)(xiu)業務中(zhong)有(you)一(yi)(yi)項是(shi)(shi)(shi)筆記(ji)本(ben)(ben)電(dian)池(chi)芯(xin)(xin)更換(huan)，就(jiu)(jiu)(jiu)是(shi)(shi)(shi)筆記(ji)本(ben)(ben)電(dian)池(chi)維(wei)修(xiu)(xiu)。隨著(zhu)筆記(ji)本(ben)(ben)電(dian)腦的(de)大眾化，筆記(ji)本(ben)(ben)配(pei)件(jian)的(de)價格(ge)也已(yi)變(bian)得能夠讓消費者(zhe)接(jie)(jie)受了(le)，換(huan)個(ge)OEM的(de)電(dian)池(chi)和換(huan)電(dian)池(chi)芯(xin)(xin)的(de)價格(ge)差(cha)的(de)也不(bu)(bu)是(shi)(shi)(shi)很(hen)大，所以(yi)一(yi)(yi)般(ban)直接(jie)(jie)換(huan)塊電(dian)池(chi)就(jiu)(jiu)(jiu)可以(yi)了(le)，原裝筆記(ji)本(ben)(ben)電(dian)池(chi)的(de)價格(ge)大概是(shi)(shi)(shi)在筆記(ji)本(ben)(ben)價格(ge)的(de)1/10，當然性(xing)能上的(de)優勢就(jiu)(jiu)(jiu)不(bu)(bu)必多說了(le)，選擇OEM的(de)還(huan)是(shi)(shi)(shi)原裝的(de)就(jiu)(jiu)(jiu)靠(kao)您自(zi)己(ji)來權衡利弊了(le)。

三：主板故障

主板故障引(yin)(yin)起的(de)(de)筆記本(ben)不(bu)(bu)充(chong)電(dian)(dian)是(shi)筆記本(ben)維(wei)(wei)修中遇(yu)到(dao)最多的(de)(de)，因為是(shi)做芯片級維(wei)(wei)修，一般的(de)(de)電(dian)(dian)源和電(dian)(dian)池引(yin)(yin)起的(de)(de)不(bu)(bu)充(chong)電(dian)(dian)在板級維(wei)(wei)修員手中就會(hui)解決，不(bu)(bu)會(hui)到(dao)我們手上(shang)的(de)(de)。

主板的故障也有兩種情況，由(you)簡到難依(yi)次是(shi)，電(dian)(dian)(dian)源(yuan)口(kou)－電(dian)(dian)(dian)路故障先說電(dian)(dian)(dian)源(yuan)口(kou)，這(zhe)個比較簡單，表現是(shi)不用電(dian)(dian)(dian)池時有時掉電(dian)(dian)(dian)，充電(dian)(dian)(dian)時斷(duan)電(dian)(dian)(dian)續，用手(shou)動動電(dian)(dian)(dian)源(yuan)口(kou)就(jiu)可作(zuo)出判(pan)斷(duan)，還有就(jiu)是(shi)電(dian)(dian)(dian)池與主板的接(jie)口(kou)虛焊也會引起不充電(dian)(dian)(dian)故障。

四：電路故障

一般是充電電路和(he)保護隔離電路出現故障。

除了芯片本身容(rong)易損(sun)壞(huai)外，其周邊(bian)電(dian)路(lu)的損(sun)壞(huai)也(ye)很多見。如比芝麻(ma)粒還小(xiao)的穩(wen)壓(ya)二極管，在(zai)早期維修工(gong)作中，沒有電(dian)路(lu)圖(tu)(tu)和點位(wei)圖(tu)(tu)，修這種故障是(shi)相當的費時(shi)間。

還有就是(shi)EC本身及周邊電(dian)路故(gu)障(zhang)，EC是(shi)充電(dian)IC的上級電(dian)路，負責開(kai)啟和(he)關(guan)閉充電(dian)電(dian)路，在這里就不做細述。

日(ri)常的檢測筆記本不充(chong)電這(zhe)個(ge)故障(zhang)的表現和故障(zhang)點遠不止上面幾種，如果您的筆記本也出現了(le)這(zhe)個(ge)故障(zhang)，可以詳細(xi)閱(yue)讀(du)這(zhe)篇文(wen)章，若還(huan)不能解(jie)決就到網上查詢更多的故障(zhang)原因(yin)。

筆記本電池充不進電怎么辦?

1、檢查(cha)電池，看看是否(fou)線路出現了松動(dong)，連(lian)接不牢的問題。

2、如果線(xian)路正常，看(kan)(kan)看(kan)(kan)電池充電器的電路板是否(fou)壞了(le)，換一個試試。

3、如果線路正常，充電器是好的，那可能(neng)是電腦內部(bu)的回路板出現故(gu)障(zhang)了。

4、一般電池用了3年左(zuo)右(you)，基本(ben)都老化(hua)了，即使是鋰電池，可以(yi)去維修(xiu)店(dian)檢測下。

5、一般電池用到(dao)20%左(zuo)右，就需要充電了，不要等到(dao)0時再充電，太傷電池了。

6、拯救小方法：用餐巾紙把電池包起來(lai)，注意多(duo)包幾層，然(ran)后用透明絞布再在(zai)外(wai)面粘好(hao)，注意要(yao)用絞布粘嚴實，不要(yao)讓里面透水，然(ran)后放到冰箱中（2----零下2攝氏(shi)度中）保存(cun)72個小時后拿出來(lai)，電池可能會恢(hui)復部分存(cun)儲(chu)功能。
