Last night I noticed a small screen flicker on my MacBook (white 2.0GHz Core 2 Duo). After looking it up on the internet I have found that a number of others have suffered from this problem. Issues go back a number of years. The problem has been associated with: a back light, an inverter and a battery software update [or lack of] (that I have read about). Of course the machine is just out of warranty by less than a month - isn’t that always the way

I’ll add to this article as and when I investigate further.
