Hi there, my 2 year old 15" MBP 3,1 has been giving me noticeably short runtimes on battery power, coconut battery shows 31% full charge capacity @ 160 cycles than originally new. Yesterday I was burning a dvd with disk utility on 70% battery power and while I was away it just shut itself down and wont power on after even with AC alone or AC+DC, but after SMC resetting it it booted up. I have Snow Leopard and power icon shows "Service Battery" if that matters. Theres no AppleCare on this mac and im obviously out of the 1-year warranty, would apple still replace it for me at no cost? I've been reading that they have a 300-cycle 80% charge "policy (or not?)" Thanks a lot!
