Hi folks.. Well, after 3 years of solid service, my MacBook Air has suddenly decided to become quite temperamental with it's battery. The problem started suddenly quite recently - when the battery got to about 18% the system would shut off. I figured, OK, I can live with this as I don't *need* the system as my daily machine and just tend to us it in bed, or when on the road. I assumed it'd become progressively worse. However I've just took it back out of sleep this evening with the battery at 49% and it's done the same! It turned off. Pressing the power button bought up the logo of the flat battery and demanding it be plugged into a power source, which is what I've had to do to bring it back on I wouldn't mind so much except this battery hasn't done anything near 1000 cycles. In fact it hasn't even done anything near 500 cycles! I'm in fact only on around 260 cycles The frustrating thing is I got this system with an extended Apple Care policy taking me up to 3 years cover but.. guess what.. it lapsed in August. Is it likely Apple would do something as a good will gesture? I've bought my fair share of Apple stuff over the years! Or am I going to need to realistically fork out the £109 for the battery replacement programme? Any other causes for this or is the battery basically toast? Not sure if the spec matters much but it's a fully maxed out 2013 11" - i7, 8GB RAM, 512GB SSD. Thanks.
