Hi,
I have a Macbook from mid 2009 and suddenly shutdown and doesn't turn on with the battery, only with the power adapter connected. The battery is connected but not charging.
I reset the SMC and NVRAM but seems to be a firmware problem. Then I saw this firmware upgrade ( http://support.apple.com/kb/DL1625 ) that may solve this issue, yes, my battery have more than 1000 charge cycles. But the installer doesn't allow me to install it.
Any thoughts?
Same problem here. I've tried everything, but no luck...
