【电脑通电自动开机】电脑一通电就开机是怎么回事呢?如何防止这种现象发生呢?这里装机吧的小编来个大家分析一下原因和解决办法。
一般造成这种情况的可能有两种:一是电源本身问题;二是设定了来电开机功能。
1.如果是电源问题,有两种可能,其一是电源本身的抗干扰能力较差,交流电源接通瞬间产生的干扰使其主回路开始工作;其二是来自主板的PS-ON 信号质量较差,特别在通电瞬间,该信号由低电平变为高电平的延时过长,直到主电源准备好了以后,该信号仍未变为高电平,使ATX 电源主回路误导通。
2.来电开机功能和电源管理有关,可能是在BIOS设置项中开启了来电自动开机的功能,这时一插上交流电源,电脑便会自动启动。如果不想使用此功能,将其关闭即可。解决方案如下: 在开启电脑时按下DEL键进入BIOS——“Power Management Setup”或者“Power Management Features”(电源管理设置)——“APM Configuration”———“Restore On AC /Power Loss”的设置项,这个选项有三个子选项,分别为“Power ON”(开机)、“Power OFF”(关机)、“Last State”(回到上一次关机状态)。电脑是通过这三个选项用来管理通电时电脑的状态。若不想使用此功能,设置为“Power OFF”(关机)即可。
