我的dell的本今天开机时提示按f1f2f5才能进系统，有一段是这样说的：
The AC power adapter wattage and type cannot be determined.
The battery may not charge.
The system will adjust the performance to match the power adailable.
Please connect a Dell 65W AC adapter or greaterfor best system performance.
To resolve this issue,try to reseat the poweradapter.
Strike the F3 key(before the F1 or F2 key)if you do not want to see power warning messages again.
Strike the F1 key to continue,F2 to run the setap utility Press F5 to run onboard diagnostics
以前我都是外接的电源（就把电池卸了
），我以为是电池的原因，把电池安上开机，又正常了，我想问一下为什么会出现这样的情况啊？？

电源管理程序没有检测到电池,只是显示提示或警告信息.不用理会.
它也说明了,如果你不想看到按F3.
按F5可以进入主板诊断程序.
电源高级管理里设置一下即可
在BOIS里把不用的都关一下！再设置电源高级管理！要确认里面的相关选项！
在BIOS中加载默认的设置就可以了
