你好,我用的是DELL1420的笔记本,最近觉得机器运行比较慢,昨天电脑开机显示如下:
The AC power adaper wattage and type cannot be determined,The battery maynot charge. The system will adjust the performance to match the power available.Please connect a Dell 65w AC adapter or greater for best system performance.To resolve this issue,try to reseat the power adaper.
Strike the F3 key(before the F1 or F2 key)if you donot want to see power warning messages again
Stike the F1 key to continue ,F2 to run the setuputility ,Press F5 to run onboard diagnostic. 以前也出现过类似的情况,不过把电池拿下来重装了一下,电源适配器也重插了一下就解决问题了,现在我也这样去做了,问题仍热存在,不知道是夏天CPU温度过高导致的,还是别的什么问题?请高手指教!!!
1. 关机,拔下电源,拔出电池。2. 插上电源,开机。3. 关机,拔下电源。4. 插上电池,插上电源。这时候应该能看到电池显示灯亮,表示已经能正常充电啦! 5. 开机。会显示“电源已接通,正充电”。6.再关机,显示电池灯亮了,就代表正常。成功率 90% 。我的是因为在使用过程中多次接入电源,才出现这种情况的。开机显示the ac power adapter wattage and type cannot be determined
