battery/charging issues with MacBook Pro
I have an older (2008) 17" Mac book Pro, with battery/chargin
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???

If this is a cheap chinese knock-off not from Apple it could be the battery. Batteries are know to be "bad right out of the box" - contact your vendor. Apple has been know to have had a bad batch of batteries.
And yes gunk builds up in the end of the magsafe... you can clean it when unplugged with and old tooth brush and some 99% alcohol... some dielectric contact cleaner is good too, let it dry for hours before using. Check the in port on the laptop too - crap builds up in there
