    Maybe this is obvious, but it's new to me and I thought I would share in case anyone else is in my situation.

    The LCD brightness setting in the BIOS is actually a cap on brightness. If you set it to anything less than max, that just sets a max brightness to which Windows will be able to set your screen. You can confirm this by setting it to minimum in BIOS, and then booting Windows - you'll be unable to change the brightness at all.

    So what you should do is set it to maximum, and just manage the brightness in software to have maximum flexibility.

    I have a Latitude E6500 running Windows 7 RC.

    That should alleviate confusion for some users, but keep in mind that this isn't true of all models. My Studio 15, for instance, has the brightness settings in BIOS, but they are controlled by what I set in Windows. If I set it to the minimum in BIOS, and boot into Windows, I can still increase it, and when I reboot into BIOS, it will be at the new setting.
