I have a 12" 1.33GHz PB Combo Bluetooth AE 80GB 512MB - When charging it always shows green. In my past experiences with Apple laptops when plugged in, if it wasn't fully charged, the light around the adapter would be orange and turn to green once it had reached full charge. This one does not do that, it is always green....even if I run the battery completely down and then start charging it. I've had charging/battery issues in the past with a 17" PB and it ended up being the logic board (but this is not similar to those issues). Is this normal? Has anyone else had any experience with this issue? Thanks!
