    I feel that the brightness 0 is now so much dimmer than before.

    Thank you lenovo, took you guys more than two years though.

    Looks the same to me. Maybe it's just your backlight degrading. :p

    If you were using non-Lenovo GPU drivers, then the brightness scale will be way different.

    Degrading should be gradual right? This happened right after I updated.

    On my T61 with the latest Power Manager (3.66), the generic Intel driver and the Lenovo driver now perform exactly the same. Previously, the default low end setting was either 4 or 0, depending on the driver. Now it's 0 on both drivers. I still use the Intel Graphics Properties window to lower the brightness even further for longer battery life.

    You should get the same level of brightness control even without the thinkvantage power manager. So it shouldnt be the software that is causing this.

    I always use my x200T before sleep, previously I have to use Vistashade at brightness 0 because it was too bright. Now I can use brightness 0 without burning my eyes.

    The X200 should have 14 brightness steps IIRC.

    I also seem to recall that they're handled by BIOS/EC, not the driver (the values that is, not setting the brightness to one of those steps.)
