Hello, a few months ago I replaced the LCD screen on my Lenovo ideapad u460 and the new screen works fine, however I am only able to set the backlight brightness to two different settings. After a fresh install of Windows 7 on a new hdd I still have this problem. I'm not sure if there is something wring with the OEM screen or if it has something to do with Windows. One important thing to note is that while the laptop is booting up I am able to adjust the brightness using the Fn Up combination and sure enough it goes through the normal brightness levels, but as soon as Windows boots up I am stuck with only the two settings again. I haven't been able to find much information on this problem and if anyone may have any idea as to what might be causing it or how to fix it, I would really appreciate it. Thanks!
