I had the issue on mine, I don't know if it comes from the backlight itself or from the inverter board that supplies the power to the backlight, but it's one of those. Reducing the brightness can make the problem come less often, and there are a number of things to "restore" at least temporarily the problem: connect/disconnect the AC adapter, switch to external screen and back... (anything that will change the software-controlled brightness, really). The problem should appear on other OSes too, though different APM handling of screen brightness may have different consequences. Jacques.
