Yeah unfortunately that is something common with a few laptop models.
The problem could be either on the cord end as sometimes the cable gets damaged. More frequently you will see that it is on the computer side.
I am having the same problem right now with a HP computer and a Dell Inpisron.
On the Dell it was the cable it had a bend that damaged the cables. On the HP it is the DC jack on the laptop side. I need a new jack or better soldering skills.
