不同品牌(pai)筆記本電(dian)(dian)腦電(dian)(dian)源適配器(qi)不能通用的主要(yao)原(yuan)因

筆(bi)記本電(dian)腦電(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)并不(bu)通(tong)用大(da)家是(shi)否遇到過這(zhe)(zhe)種(zhong)情況？在(zai)某(mou)些場(chang)合(he)突(tu)然筆(bi)記本電(dian)腦電(dian)池供電(dian)不(bu)足，又沒有(you)帶電(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)，工作還有(you)一點(dian)點(dian)沒有(you)完(wan)成，這(zhe)(zhe)種(zhong)情況非常令人焦(jiao)慮和尷尬。有(you)些朋友在(zai)這(zhe)(zhe)個時候(hou)可(ke)能(neng)試(shi)圖借用他人筆(bi)記本電(dian)腦電(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)，可(ke)是(shi)大(da)家要注(zhu)意了，不(bu)同(tong)品牌筆(bi)記本電(dian)腦電(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)是(shi)不(bu)能(neng)通(tong)用的，至少目前是(shi)這(zhe)(zhe)樣。

不(bu)同(tong)品牌筆記本電腦電源(yuan)適配(pei)器不(bu)能通用的主要原因有三：

一、接口不同

多(duo)數筆記本電(dian)腦電(dian)源(yuan)適(shi)配(pei)器品牌(pai)間的(de)接口不(bu)同，這(zhe)就意(yi)味(wei)著(zhu)使用其他品牌(pai)的(de)電(dian)源(yuan)適(shi)配(pei)器根本不(bu)能(neng)插入(ru)到你的(de)筆記本電(dian)腦進(jin)行供電(dian)。接口不(bu)同是相對安全(quan)的(de)，因為至(zhi)少(shao)你不(bu)會插入(ru)電(dian)流或電(dian)壓不(bu)符合的(de)電(dian)源(yuan)適(shi)配(pei)器給(gei)筆記本電(dian)腦供電(dian)，而導致電(dian)腦硬件損壞。

二、電壓不同

不同(tong)品(pin)牌筆記本電(dian)(dian)(dian)腦電(dian)(dian)(dian)源適(shi)配器電(dian)(dian)(dian)壓是(shi)不相同(tong)的，例如：一般(ban)情況下IBM是(shi)16V，Dell是(shi)20V，Hp是(shi)18.5V，Sony是(shi)19.5V等。由此可見(jian)，即便電(dian)(dian)(dian)源適(shi)配器接口相同(tong)，也不能使用不同(tong)品(pin)牌的筆記本電(dian)(dian)(dian)腦電(dian)(dian)(dian)源適(shi)配器進行供電(dian)(dian)(dian)。

三、電流不同

不同(tong)品牌筆(bi)記(ji)本(ben)電(dian)腦電(dian)源(yuan)適配器電(dian)流也(ye)是(shi)(shi)不相同(tong)的，例如(ru)：一般情況下IBM是(shi)(shi)4.5A，Dell是(shi)(shi)3.34A，Hp是(shi)(shi)2.7A，Sony是(shi)(shi)4.1A等。

其實，相同(tong)品牌(pai)筆記(ji)本電(dian)(dian)(dian)(dian)腦(nao)電(dian)(dian)(dian)(dian)源適配(pei)器的電(dian)(dian)(dian)(dian)壓和電(dian)(dian)(dian)(dian)流(liu)也(ye)(ye)不盡(jin)相同(tong)。所以(yi)，即便(bian)是相同(tong)品牌(pai)筆記(ji)本電(dian)(dian)(dian)(dian)腦(nao)間竄用電(dian)(dian)(dian)(dian)源適配(pei)器也(ye)(ye)要確認電(dian)(dian)(dian)(dian)壓和電(dian)(dian)(dian)(dian)流(liu)規格(ge)。
