Apparently, you don't have a teenager in your life. They seem to know so much about computers.
Just describe the problem.
LOL, are you sure you have the right cord? Look in the hole and see if there is something in there blocking it.
Double check to make sure that you have the right charger and you didn't get it mixed up with another machine. Don't swap chargers between laptops as there are often differences in voltage that can cause you to end up destroying the laptop. If you're certain you have the right charger then it probably means that the frame of your machine was damaged and it needs major repairs.
Unless it's an IBM T-Series Thinkpad, an HP Elite series machine or one of a handful of other commercial laptop models then the machine is basically totaled. It isn't worth it to pay for those kinds of repairs for a DELL , Toshiba or an HP consumer grade machine.
