Lenovo T440P display is dim on resume when "dim screen" option is active. It does go back to max if I hit the brightness up key, but it is annoying to have to do that every time. It stopped happening for a while, and then started doing it again (I think it was because of an update). It happens on battery and on AC. System details below.
