I've got an ibook g4 1.33 12" (the new ones with 512 Mb of built-in RAM ). The problem is, when the battery is charged, orange light never becomes green. When I bought it, everything was normal. Suddenly the green light disappeared. Fully charged (it is always 99% charged even if macosx says that it is fully charged. But regarding the information on the apple's web site this is normal, so I believe in them ) or not, there is always an orange light. I resetted PMU but nothing has changed. I also checked the bottom: when the little button on the battery pack is pressed, all the lamps are green, so it means the battery is fully charged, but why the adapter is always orange??? Technical support could not solve the problem (in approx. 1 month!!!). They said that they have changed the board but I have always the same problem. Have you got any suggestions? There is anyone experienced the same problem before? I don't know what to do. I bought it 3 months ago, and this is really annoying. I want my normal iBook back, with orange and green light, not just orange. I've forgot to mention: after seeing 99% charged battery indicator, I've waited for 4 hours but It does not becomes green as indicated in other posts.
