What the heck? I had just plugged it in when the low battery popup came on, the light was on the magsafe, and the popup went away. About 10 minutes later the screen goes black and I can't turn it back on. Now, I did use my 2 yr old blackbook's power adaptor cuz it was convenient, and we have had some problems with that adaptor not giving power on occasion, but when I got out my new mac's adaptor and plugged it in the computer turned on, but had restarted (not like when you just let the charge run down, this was a full restart). AND, my battery is not charging! It says the charge time is 10:00, and iStat says health 97%, cycles 115, and charge 0%. The only thing that is changing is that iStat's charge time counter previously said 11 hrs, now says 10:28. Do I need a new battery? I've been pretty dissatisfied with the current battery, as it keeps bouncing between 100% and 97% health, whereas my old blackbook still shows 100% health after around 640 cycles. Help?
