I've had this iBook for about five months now. Over the past few days while using my computer and having the brightness down to one above zero, I've noticed that the left side of my screen is not as bright as the right side. If I crank up the brightness a bit, it isn't as noticeable. This isn't the first problem that I've had with this computer. In October, the iBook had to be sent in for repair after some cables had to be re-seated on the logic board. I don't want to send this computer in again for another repair, especially with school beginning again in a few weeks. Is there anything that I could possibly do about this problem myself without having to take it to Apple for repair?
