I LOVE my new 17" Al PB, the look and screen and feel. All is well - EXCEPT... This past Friday, I put in a new extra battery I bought from Apple and went home with the 17". Machine would not boot at all, even when on AC power cord. Even when I changed the power adaptor cord. Battery showed 1 green light when button pressed. On Monday: Found that with the original (5 green light) battery, 17" booted just fine. Apple Tech: Concluded over phone that the 17" was not charging any battery at all!!!! Sent it back and am awaiting word if it can be repaired. Clearly, since its arrival on Mar 21, I didn't know this problem since I usually use it with AC power and it arrived with enough power for moments otherwise. Questions: 1. Can you all check to see if your battery is being charged ok? (if yellow ring turns on, on the power plug, it shows it is charging). 2. Any similar problems out there? 3. Any ideas? 4. For technically knowing folks: Is this likely to be fixable inside-apple? Or should I insist on a new machine? Pleasse feel free to distribute this to other Mac sites in case anyone has ideas.
