    At a perfect angle, I noticed a small amount of light bleed under each individual key of my rMBP. Tilt it and you'll see specs of light within the cracks/seams. It's not the backlight of the keyboard, turned off. Try it, report results.

    Perfect angle
    Small amounts...

    Does this bother you on a regular basis? Could light bleed impact the computer at all (battey life etc.)?

    Sorry if this comes across as sarcastic...actually curious.

    Perfect angle for some keys and different angles for other. ie. one angle, you see the light bleed on the power button, another angle and you see it on the "A" key.
    It doesn't, but I'm just pointing out a problem. Who knows.... maybe.

    Anyone else see it but me?

    If you're describing what I think you're describing, that's a characteristic of pretty much any backlit chiclet keyboard. If not... maybe another picture in lower lighting would help, cause I can't see anything at all in the one you provided.

    Check right beneath the command/option key.

    Yes, it's completely normal. They keyboard is not sealed, and the keys move up and down. What exactly did you expect?

    It's not really lightbleed, rather light reflection. cover keyboard with hand just above the phenomena

    No, I caught that. Let me offer a possible explanation.

    Your backlit keyboard isn't composed of LEDs under every key. Rather, there are two or three in the palm rest or adjacent to the keyboard, and light is carried to each key, usually by a transparent plastic grid or similar that reflects the light internally and diffuses it, not unlike a light pipe or a fiber optic cable.

    So if your screen is on, and light is entering that grid from another point, it would conceivably be reflected and distributed across that grid as it would from the light source it was designed to work with.

    As I said, this is pretty normal on backlit keyboards, though generally so dim as to be inobservable.

    That's like saying light bleed from a monitor is normal with "gaps".

    That's why I said "that's like"

    Let's ignore the fact that every backlit chiclet keyboard in the history of personal computers has this exact characteristic. It's not relevant. OP has been screwed over royally. Apple need to compensate the OP a minimum of $300,000 for the psychological hardship this has caused.

    Its some light getting reflected by plastics under the keys, if at all (I can't see any light bleed on the picture your posted). I fail to see how this can even remotely be considered a problem.

    Look under the option key.

    Yes, it would be normal for a monitor with gaps in it to have light bleed, but that's not how monitors are build. Keyboards have gaps in them, what do you think will happen, the light will just choose not to go through it?

    Looks like a reflection from under the key, probably due to the light guide under the keys that distributes the backlight.

    The keys also have white plastic pieces underneath that are part of the physical movement mechanism.

    It's definitely not 'light bleed'. I really don't see why this is a problem.

    FOR GOD SAKES PEOPLE. It'S reflection from the screen.

    Turn screen light FULL and cover the bottom half of it - the "light bleed" magically disappears.

    And it's impossible to remove that effect without significantly complicating and redesigning the encosure...

    Fixed!

    I duct taped a USB keyboard on top of the laptop keyboard. Sure I can't close the lid any more, but that's a small price to pay for sweet, sweet keyboard darkness.
