2 months ago I started getting the 'battery not charging' message when I plugged in my macbook. If I left it plugged in over night it only charged to about 15% and it wasn't getting enough power to run off of the power adapter so once the battery died it shut off. I bought a new adapter, which solved the problem for a while, but then it started doing the same thing again. So this time I thought maybe it was the battery (it was 3 years old with around 850 cycles - although my computer was still saying it was in 'good' condition) My new battery arrived yesterday and it still won't charge. I've done a Hardware test - holding down 'D' when I turn it on - but it is saying there is no problem. Any suggestions or do I need to go to an apple store (there isn't one nearby - 2 hour drive one way - which is why I haven't taken it yet) Thanks in advance for any help.
