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 available
please connect a DELL 90w AC adapter or greater for the best system performance
strike the F3 key (before F1 or F2 key) if you do not want to see power warning message again strike the F1 key to continune ,F2 to run the setup utility
按完F1后能进如系统……重开机还是会响,并且提示上面的信息,请问该怎么弄?
