<P>您好，非常感谢您的方法。</P><P>我尝试了一下拔掉主板上纽扣电池的方法还原了bios设置，但是不确定这种方法是否存在隐患，还原之后开机暂时正常。</P><P>之后因为怀疑是bios升级问题引起的内存不兼容导致无法识别，对bios进行了降级更新，重启电脑后开机仍无法识别内存开始三长两短警报，再次拔掉纽扣电池后目前暂且正常，如果之后再出现这种情况参照您提供的方法试一下。</P><P>有一个小疑问，不知道bios升级安装后是不是会校验机器上当前连接的硬件设备和出场设备是否一致？目前我使用的内存为两根2400 DDR4 8g内存，原装内存为单条8g 2666，不知道是不是这个引起的bios无法识别内存因而警报。</P><P>再次感谢提供的方法，以后就不需要拆开电脑进行bios设置还原了，感谢！</P> Thu, 26 Mar 2020 17:11:47 GMT
