Someone please help me. I have a problem with my macbook. I plugged the charger to my macbook but it appears battery is not charging and i can see the green light at the charger but the green light is not as usual light, i mean its a little bit light. Now i can't start my macbook, i tried to plug the charger to my macbook air and it worked fine. Do i need a replacement battery? Sigh =.= i have used it only for 5 months.
