    LED Screen Questions
    I just bought a MBP from BestBuy, 2.4ghz model. I am a first time Mac user, switching from a Toshiba notebook with Vista. (my job is in IT dept of a company on Windows). I want to verify my screen is backlit by LED, not CCFL. How can I tell? It is the 15" model, S/N W88305CEYJX.

    My Toshiba is a few years old now, and is CCFL backlit. The screen used to be much brighter--I assume LED never loses brightness over time as a fluorescent light will?

    You can check your model number\SN on the Apple site to verify that it has an LED backlight. I believe it does.

    As far as LED versus CCFL goes, both will degrade in brightness over time. The difference, however, with a LED backlight is that it uses much less power and has a significantly longer life than CCFL. By the time your LED backlight is noticeably dimmer, you'll be long overdue for a new machine.

    You definitely have an LED backlight...

    You don't have to worry about checking

    Yes its an LED don't worry. Crank up the brightness and that should clearly tell you that as well.

    The easier way for me to tell is by adjusting the brightness and carefully watching it. The LED lit displays have a much notchier increment (if that makes any sense) whereas the cathode based units are smoother when being turned up and down.

    Based on your post, I can almost guarantee you have an LED based display.
