Just recently my battery charger for my compaq laptop has been acting like it has a short in the wire. I have to bend the cord in various directions trying to get it to charge. Finally if I find the right place I can get it to charge my battery. It's a pain in the butt trying to get this thing to charge. Can I get a universal laptop battery charger or will I need to get the same one from compaq? Has anyone else had this problem? Thanks for any help.
