#495 closed defect (fixed)

protective film left on LCD in B1 build

One of my laptop units still has the protective film over the LCD which decreases the visibility, has scratches, etc. It's easy to spot it if you look for the waviness of the plastic protective film

These protective films are easy to see if their are air bubbles, but hard to see otherwise.

This defect can be remedied by taking apart the laptop and removing the protective film (it peels off). In future builds we need to develop a way to make sure operators take off the protective film

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.

the laptop protective film will have a piece of tape on it to identify it in B2 and subsequent builds. This issue is closed.
