注意：
1、若使用系统为Windows 8/8.1/10，需要先将快速启动功能关闭，之后才能进入BIOS。
关闭快速启动方法：
打开控制面板，点击“硬件和声音”、再点击“电源选项”、再点击“选择电源按钮的功能”、再点击“更改当前不可用的设置”可以看到“关机设置”中有“启用快速启动(推荐)”的选项，而且此选项默认是开启的，取消选择“启用快速启动(推荐)”，然后“保存修改”即可关闭Win8快速启动功能。
2、预装Windows 8、Windows 8.1的消费机型可以在关机状态下按一键恢复按钮，在菜单中选择BIOS Setup可进入BIOS。
3、部分机型开机后按F12，在启动项菜单中选择Enter Setup可进入BIOS。
