Laptop Battery will not charge

Hi everyone….

i purchased an ACER Aspire 3680 around 3 weeks ago it runs on windows vista and its been running pretty smoothly….i handle it with great care. But i now find that by battery just will not charge. i plug it in and nothing happens the indicator light does not come on at all. i tried the power cable in another laptop and it works great, but in mine it doesnt work at all anyone with solutions for this?, i’d greatly appreciate it
