i recently bought a macbook pro 15 at the end of august this year, 2010. after dropping it once, i seemed to notice the keyboard backlight was dimmer than usual. after comparing it to a few friends of mine that bought the same computers in august also, i noticed that the lighting on their keyboard is brighter and also different. peering under the keyboard on mine, i can see the individual light sources, "little dots" and my friends dont have these at all. they have what it looks like a whole sheet of light under the keyboard. this is really bothering me and a went to my campus' tech store where i bought it and they say nothings wrong with it. my question is, it there something wrong with mine? how is the keyboard suppose to light up? and if so how can i fix it?
