Why my laptop A32-F82 charger doesn’t working?

Every so often I find myself constantly unpluggin and repluggin my charger into my laptop to get it to charge. Without doing this, it won’t charge at all… But today I’ve tried using my daily technique and for some odd reason my laptops not having it. It’s no longer chagring. HELP! My A32-F82 Batteria life is at exactly 29 minutes with 24% remaining. What should I do? http://www.buonabatteria.com/asus-a32-f82.html What could be the real reason for this? http://www.batterietutti.com/asus-a32-f82.html
