I have a early 2008 MBP, santa rosa intel core 2 duo I think I upgraded to snow leopard, and thats when the battery icon started to tell me that i needed to service my battery. I wasn't in the financial position to replace the battery, so i figured i would continue using my MBP with the power supply. But sometimes it would disconnect and i would run on battery power. The battery life would only last me about 30 min then less and less. It wouldn't give me the usual warning about reserve power it would just restart. Now it wont turn back on the HD and disc drive begin to start but then it stops booting up the light on the latch begins to glow then it flash intermittently does that mean anything?? any ideas? i hope this has some fix?
