My screen is too light for me at night. I want to set the min light level lower. So I add a new line to "BacklightLevels". This is what I changed:

Device (PNLF) { Name (_ADR, Zero) Name (_HID, EisaId ("APP0002")) Name (_CID, "backlight") Name (_UID, 10) Name (_STA, 0x0B) Method (RMCF) { Return(Package() { "PWMMax", 0, "BacklightMin", 10, "BacklightMax", 0xad9, "BacklightLevelsScale", 0xad9, "BacklightLevels", Package() { Package(){}, 0, 10, 11, 13, 16, // line added 18, 19, 21, 24, // line added 35, 39, 44, 50, 58, 67, 77, 88, 101, 115, 130, 147, 165, 184, 204, 226, 249, 273, 299, 326, 354, 383, 414, 446, 479, 514, 549, 587, 625, 665, 706, 748, 791, 836, 882, 930, 978, 1028, 1079, 1132, 1186, 1241, 1297, 1355, 1414, 1474, 1535, 1598, 1662, 1728, 1794, 1862, 1931, 2002, 2074, 2147, 2221, 2296, 2373, 2452, 2531, 2612, 2694, 0xad9, }, }) } }

It is wrong. You must provide exactly the same number of backlight levels as originally present. (65 levels including the 0/black level)
