很多小伙伴在使用电脑时,某天家里突然没电了,所以自己的电脑电量撑不了多久,就设置了节电模式,但在节电模式下不知道怎么开机,下面小编就给大家分享电脑节电模式怎么开机的解决方法。
一、首先检查主机是否正常工作:
开机后,我们按一下键中的“Num Lock”键,也就是台式键盘右边的数字开关切换键。如果按了数字锁定键之后,锁定灯可以正常亮起或熄灭,可以断定系统动作正常,但不排除由于显示硬件的问题引起的无信号输出。
注:除了按“Num Lock”键,还可以按“Caps Lock”这个大小写切换键。
除此之外,还可以将音响打开,聆听是否有正常开机的提示音。如果提示音也正常的话,基本可以断定主机没有什么问题。
二、由显示器本身引起的开机无法显示故障:
先检查显示器电源是否打开,可以观察显示器上的状态指示类是否是一闪一闪的,也可以按显示器电源键,观察屏幕是否会亮起显示无信号之类的提示,之后再熄灭。
如果打开按显示器电源,显示器无反应,状态指示灯也没有任何变化的话,很有可能是显示器电源未接通引起的,观察显示器的电源,换一个接口试试。
三、脑硬件原因引起的显示器无信号:
当出现这种情况时,就是按大小写键或数字键切换没用,也就是说主板无法把信号正常的输入和输出。那么明显就是硬件问题了。
内存接触不良
内存接触不良,是最常见的引起无信号输出的原因之一。将内存条拔下来,用橡皮擦拭金手指后,复装,观察电脑是否正常启动,复装后故障依旧,建议更换内存条再次尝试。
电容暴浆
检查主板上的电容是否有暴浆现象,如果有此类问题,可以尝试更换暴浆电容后,再次尝试开机。
以上就是电脑节电模式怎么开机的解决方法,希望能帮助到大家。
