Ok I just bought a new battery for my 466mhz Key Lime iBook (DVD FireWire SE) It worked fine and said it would last for up to 3 hours! (YAY!) Now it charged to 100% but I have used it down to 67% now it won't charge past 67%! The power adapter light is green, but it says 67%, when I try to go to view the Time under the battery menu it says "Calculating..." How do I fix this? I have tried restarting. Please help...
