Problem re: screen brightness adjustment


New Member
So yesterday I was tampering with the energy settings to find ways to make my computer consume less electricity. Now this morning as I booted up my laptop (a Lenovo L440), the screen brightness setting appears to be stuck between two settings (one at about 70% and the other at maybe 80% -- these are just estimates, as I'm referring to the graphical scale that shows up in the top left corner) when I try to set it using the built-in hot buttons. I have tried resetting the energy options to defaults, but to no avail. While this isn't a huge problem, I would like to know what's gone awry so I can reset it. I assume these changes would be deleted if I deleted the settings folder, but I don't know exactly where in the system it's hiding.
