I just received a so called new genuie battery for my macbook 13'' , 2008 aluminum. But mac couldn't start if only with the battery. When I plug in the charger, there shows green light, so whcih means it doesn't charge the battery at all. In addition, I have to press the start bottom for a while, in order to start the computer. By press normally, I can hear some noise seems like from hardware, but nothing happens then. It is the same sound as, when only electricity connects to mac but without battery, my mac suddenly become black screen (shut down without any notification).
Does anyone know what's problem with my mac or the new battery or both?
I really appriciate if anyone can help me with the problem bother me a lot!
