I got Acer Aspire 4535G laptop from singapore. Though it was all smooth going, but suddenly dont know what happen. when i m keeping the laptop on charge it works like charm. as soon as i remove it from power the battery doesnt last long for more than 2 mins. its gets off. i charged my battery completely still its lasting only for 2 mins. While charging it starts from 0% and it takes 20 Mins and shows 100% charged. but still it cannot last for more than 2 mins when i unplug from the charger. can any one help me on this. where is the problem arise in it
