So my Macbook is 2009, and has been used a lot (work) recently the charger stopped charging. It would glow green, and the computer would recognise it was connected, but it would say 'not charging.' I tapped it on the desk a few times, then plugged it back in, wiggled it around a bit and it would charge. As soon as I unplugged it I would have to do the same again. Today I did the same routine, but this time even though the light is orange or red or whatever (I can't tell which) it is not charging! And my battery is already down to 38% from 100% this morning!

Oh, and I did the reset thing (taking the battery out and holding the power etc) to no avail.

    I note that the the battery has gone thru 1019 cycles. That is about the life expectancy for a built in battery according to Apple.  It looks like it is time for a new one.  (If it is a user replaceable battery, the cycle life expectancy is 300!)
