I am new to Apple so I'm sorry if this is a stupid question. I have an iBook G3 (600 MHz) with Mac OS 10.3.9 installed. When I got it, it had a dead battery. So I got another battery. Andi it worked fine when I used it first time. But when I tried to recharge it, the color is always orange. Is this normal? Now I turned the computer on and right now I am working with the battery. It says that I have 3 hours. But when I turn Airport on, it becomes 6 minutes! What is wrong?
