I have tried to get my display to stay at a level just slightly lower than max brightness. I have manually tried to set it in the Windows power management area and the Lenovo tool.
As soon as I turn off the computer and turn it back on it reverts back to maximum brightness. Does anyone know what the problem is and how to resolve it? I do have the most recent BIOS, and this is a W510.
If you want your computer to maintain a brightness lower than max, use "Custom' as the power setting and tweak from there. I was trying to manipulate "Maximum" and that is why it was reverting.
