【求助】【请教】8560w开机问题

bpwan401

最近几天8560W开机出现问题。刚开始是开机风扇狂转，屏幕全黑无任何显示。长按开机键开机，10S后才进入开机引导程序界面，正常开机后，只要供电，左下方侧面从左数第三个灯在红白交替闪烁，就是带闪电标志的那个灯。然后运行正常。拔掉交流电源，电池无法供电。
搜索论坛，怀疑BIOS问题，我用的F5.0，但是无法刷回F4.2。CAPS LOCKS和NUM LOCK这俩键盘灯不闪烁。
会不是电池问题？请教各位！

双灯闪烁在CQ40这类机器中比较常见，一般是开机加电屏无显示，加电10多秒后大小写和数字键盘灯开始闪烁，其实这些闪烁的次数是有含义的！就类似于台式机主板报警声一样，下面是惠普官方网站给出的报警次数含义：

为了简单点我就简单翻译成中文的如下:
闪1下：CPU故障
闪2下：BIOS损坏故障
闪3下：内存不能正常工作
闪4下：显卡不能正常工作
闪5下：主板出现故障
闪6下：BIOS验证失败

惠普英文官方网站的原文是这样滴：
