I have a Asus K72JR laptop. I have replaced the battery (http://www.caccu.nl/asus-k72jr-batterij.html) and the charger. While the laptop will run on AC power it will not charge the battery. It says plugged in not charging. If I restart the laptop I get an error screen that says the charger is not recognized. Is there a solution to this? I know there is an identification pin in the plug end of the charger and it is still there. Any suggest is welcome.Thanks in advance.
