I HAVE A HP ZV5000, THE BATTERY WILL CHARGE HOWEVER THE CORD NEEDS TO BE PUSH IN REALLY HARD. IT DOESNT SEEM LOSE AT ALL, HOWEVER IT NEEDS FORCE TO STAY CHARGE OTHER WISE IT WOULD NOT CHARGE. RECENTLY, I HAVE TO PUSH THE LAPTOP AGAINST THE WALL TO KEEP THE BATTERY CHARGING. I WANT TO KNOW, IS THERE ANYTHING A CAN BUY TO FIX THIS PROBLEM?
