Title:

battery/charging issues with MacBook Pro

Text:

I have an older (2008) 17" Mac book Pro, with battery/charging issues. Recently we got the "service battery" warning, and the battery was showing a health of 45%. So we bought a new battery. The new battery arrived approximately 50% charged and it began to charge once we installed it, but showed 100% health, and only 1 cycle after the initial charge. We noticed that the little LED lights on the Magsafe connector would not always be on either green or amber. The system worked fine on the AC adaptor though. On checking we notice a couple of the little pins in the magsafe connector seemed to be stuck in a depressed position, and wiggling it around a little would SOMETIMES make the led function again and the battery would charge. Eventually it would no longer do that.

So we bought a new AC adaptor. Got that and plugged it in to a nice green LED. Decided to cycle the battery at least once so used it on battery power (which was now at 100%) until it went to sleep at about 5%. Several hours. We didn't time it. So we reconnected the adaptor and the computer works again on AC, BUT.... the battery is not charging.  No LED on the magsafe connector comes on at all. The battery is still at about 5% charge and NOT CHARGING. The indicator in the menu bar indicates the battery IS CHARGED, and iStat pro says so too, but it's not. We have reset the PMU. System profiler reports the following...  Any suggestions???
