[Trac #495] protective film left on LCD in B1 build

[Mary Lou Jepsen]

Every single unit has the protective film still on the polarizer, they were
not removed by Quanta (we can get this next time!).  You can take off your
protective film, carefully, it's only 4 screws - all on the bottom of the
brick (the brick is the LCD - motherboard assembly), you have rotate the
brick to the left, unscrew the two screws that you can get to (philips
head), and then rotate to the right and get the other two screws.  

Next take off the left and right short green things (part of the "bumper),
and then take off the plastic face plate over the LCD.  Now you can peel the
thin protective layer of plastic off the polarizer.

SEPARATE SUBJECT (and not really for bug-trac - but for your knowledge): the
polarizer surface isn't rough as it should be to give anti-glare, this is
being addressed and can hopefully hit the B2 build, but if not it will hit
B3.  Mary Lou has an initial sample on her laptop that has been retrofitted.
This will eliminate the very slight "mirror" like effect in certain,
non-diffuse, lighting.
