my macbook was not in use for 2 weeks as I was away for the holidays. When I got home, I turned it on and plugged in the magsafe charger only the power bar is showing 0% and says "Battery is not charging". I know that it is not the charger as my other macbook (from work) charges fine with it. When I first turned my computer on it said that there was still 71% left in the battery, then the screen went gray and a bar showed up on the screen showing that the computer was in the process of 'thinking' or loading - it booted up and then showed 0% 'battery is not charging' and i can't seem to fix it. i tried to restart and even tried an SMC reboot after reading that suggestion on another site. any ideas what could be wrong?
Mine died after 44 cycles. AASP were happy to replace it, don't stock them though so I've got to go and pick it up tomorrow. Two replaced batteries in 18 months, obviously something wrong...
One, for the reason mentioned before - unit will shut down if you bump the magsafe connector and, two, when you run without the battery installed the CPU is throttled down to about 50% or normal.
Apologies for the delay in responding - been knocked out by a virus (human physical not computer logical!)
My MacBook was less than 1 year old, also covered by Apple Care (which cost £169 extra).
The Apple person was very helpful - but was careful not to commit himself as to what the problem might be - he did not seem surprised nor did he indicate it was an unusual problem . . . .
