There is no charge in the battery of the laptop. All you need to do is take the cord and plug into the circular port in the right-hand side of the laptop. Make sure the other end of the cord is plugged into a working outlet.

My Dell 1558 stopped working after I changed 3v CMOS . When I press power button a light blinks and that is all. If I turn on an adapter, there will be no light at all. No power in all cases.

The reasons are not covered above
