标题: 联想昭阳6940cfe故障 [打印本页] 作者: 上海长宁 时间: 2008-11-4 10:06 标题: 联想昭阳6940cfe故障 一台联想昭阳6940cfe，能开机，本来硬盘坏了，现在把硬盘拆了，自检到鼠标安装成功后就不动了，按F2进不去BIOS，期间电脑没有死机，安Ctrl＋Alt+Del可以重新启动，启动后还是停在启动画面下不去。

开机就显示到这里不下去了，另外主板上有三组跳线，会不会是跳线问题，没有跳线说明书，随便跳了下没用。大家看看是什么问题，谢谢作者: 东莱游子 时间: 2008-11-5 10:23
换内存试一下，不行就重刷BIOS吧，昭阳69，80系列用的是大众A430/A450的主板。作者: 经纬度 时间: 2008-11-5 17:26
同意楼上的思路,做法>>>>作者: 上海长宁 时间: 2008-11-7 21:03
看了下主板是A450的，找不到下载BIOS的地方，有知道的朋友指点一下，谢谢作者: 不想修了 时间: 2008-11-7 22:02
这种情况是BIOS程序的问题。作者: 上海长宁 时间: 2008-11-7 22:47
如果要刷bios的话，是不是要把bios芯片从主板上焊下来，拿到编程器上刷啊。我拆开看了下bios是焊在主板上的，是A450的作者: 横翔捷出 时间: 2008-11-8 14:04
69系列太爱坏BIOS了，见了就先刷BIOS再考虑其他能省不少事作者: 胡永斌 时间: 2008-11-8 20:33
不接 键盘，鼠标，硬盘，有可能触摸鼠标有冲突作者: 上海长宁 时间: 2008-11-12 22:06
谢谢楼上各位，重新刷了BIOS后好了，就是联想的开机画面没有了，但不影响使用作者: 静远 时间: 2008-11-12 22:55
这个BIOS在哪里下载的啊？我手上正好有这样一台机器！作者: 鞍山 时间: 2008-11-14 12:22 标题: 我也有该型号的机器，求FIC A450 BIOS 我也有该型号的机器，求FIC A450 BIOS 先拜谢了 as_guowei@163.com作者: 上海长宁 时间: 2008-11-18 09:25
加QQ，我发给你，注明450bios，一般晚上在线。349822462作者: 昭阳天逸 时间: 2008-12-18 11:53
