Question about Gateway M-1628 Notebook
I have the same laptop, and the same problem. I went into the BIOS settings and disabled BIOS power management features. Windows can still use the power management features, but it is not competing with the BIOS doing the same thing.
This helped reduce how often the brightness pops back to max, but doesn't completely solve the problem. It will still go to max, and most of the time back to the set brightness after a second or two. Very annoying, but better than just being stuck at max brightness.
I think either the backlight inverter is buggy, or the driver that talks to the inverter is buggy. This is my biggest complaint with this laptop.
