一、電源適配器功率怎么算
電源適(shi)配器(qi)功率的(de)大小會(hui)影響到能否給電器(qi)供電,以及充電效率的(de)高(gao)低,一般(ban)來說,電源適(shi)配器(qi)功率在銘牌上(shang)都有標識,如果沒(mei)有的(de)話,也可以自己計算(suan)。電源適(shi)配器(qi)功率的(de)計算(suan)方法是:
1、找到電源適配器的(de)銘牌,看上面的(de)參(can)數(shu),找到輸(shu)出(chu)的(de)參(can)數(shu),一般格式為(輸(shu)出(chu))O/P:xV/xA。
2、用輸出(chu)參數的電壓乘以電流即可得到電源適(shi)配(pei)器的功(gong)率,比(bi)如輸出(chu)參數是10V/4A,其功(gong)率就(jiu)是10*4=40W。
二、電腦電源適配器功率不夠會怎么樣
在選擇適配器的時(shi)候要(yao)注意輸(shu)出電(dian)壓和電(dian)流的大小,選擇合適功率大小的產品,不(bu)然(ran)可能會對電(dian)腦造成(cheng)一定的影響,嚴重情況(kuang)下還會損壞電(dian)腦:
1、沒有反應,無法打開
電(dian)源適配(pei)器功率不夠會導致電(dian)腦(nao)電(dian)源供電(dian)嚴重(zhong)不足,具體表現為有時能正(zheng)常開機,有時需要按幾(ji)下才能打(da)開。
2、硬盤出現怪聲
筆記本電腦搭配太多存儲設備,或者是電源適配器功率太低,在供(gong)電方面不能滿足多個(ge)存儲設備,就有可能出現開機不能通(tong)過啟動自檢的情況。
3、經常重啟和進不了系統
供電不足還(huan)可能導致(zhi)開機登陸不穩定,有時(shi)在啟動畫面那(nei)里就定著不動,有時(shi)會(hui)在啟動過程中會(hui)自動重啟。
一般(ban)來說,電(dian)(dian)(dian)源(yuan)適(shi)配器(qi)功率(lv)不(bu)夠主要(yao)就是(shi)會(hui)導致電(dian)(dian)(dian)腦(nao)供電(dian)(dian)(dian)不(bu)足,那么電(dian)(dian)(dian)源(yuan)適(shi)配器(qi)功率(lv)不(bu)夠怎(zen)么辦呢?解決(jue)方法就是(shi)換一個更(geng)大功率(lv)的電(dian)(dian)(dian)源(yuan)適(shi)配器(qi),或者(zhe)減(jian)少一些(xie)電(dian)(dian)(dian)腦(nao)的用電(dian)(dian)(dian)項目。
三、電源適配器功率大了能不能用
可以,但(dan)是必須要求輸出(chu)電壓(ya)相同(tong)。
對于電源適配器,在(zai)輸出(chu)電(dian)(dian)(dian)(dian)(dian)壓相同的(de)(de)(de)情況(kuang)下,輸出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大(da)(da)的(de)(de)(de)是可(ke)以替代(dai)輸出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)小(xiao)的(de)(de)(de),也(ye)就(jiu)是說(shuo)即使(shi)(shi)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器功率大(da)(da)也(ye)是可(ke)以用的(de)(de)(de),這是因為電(dian)(dian)(dian)(dian)(dian)器的(de)(de)(de)功率決定了電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器的(de)(de)(de)功率,即使(shi)(shi)你用的(de)(de)(de)是大(da)(da)功率電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配器,它也(ye)只會(hui)提(ti)供電(dian)(dian)(dian)(dian)(dian)器要求(qiu)功率大(da)(da)小(xiao)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu);并且替換(huan)成輸出(chu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)更大(da)(da)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)后,電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)(de)負(fu)荷變(bian)小(xiao)了,電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)(de)發熱量就(jiu)會(hui)變(bian)小(xiao),可(ke)靠性(xing)更高。
