I just bought a used early 2008 MBP (last pre-unibody model) to use strictly for my college classes. Upon inspection everything was mint and in well working order except the battery. The issue isn't a normal "the battery is just dead" run of the mill, its strange. I can charge the MBP fully but it can drain down to about 85% and it shuts off. If I press the indicator button on the battery, four lights still light up even though I can't boot without it shutting off again. I checked my battery information with coconutBattery. It reports back that the battery has only gone through 94 cycles and should have 43% health (or about 2427/5600 mAh). You would think that the battery would at least last longer than 7 minutes off of AC power. I have a new battery on the way but is there any at least temporary solution to the problem in meanwhile?
