Unfortunately i was away from home for the last 3 months and i forgot to remove the battery from my macbook pro 2,2. Now when i use the macbook pro it turns off suddendly when the battery is at 79% charge.... I tried to callibrate the battery and reset the SMC, but i see no change... Is the battery dead? And even if it is shouldnt i get a warning or something before it goes dead? Is there anything that i can do or should i start looking for a new battery? I must mentione that this happened also after upgrading to snow leopard. I do not know if it has anything to do with it, but i remember when i upgraded to leopard i had my battery replaced under warranty cause the computer would turn off suddendly when the battery would each 30%... Thank you in advance for any help, Bezbozny.
