there's been a little done in regards to changing the keyboard color. i think xoticpc offered it as a option on some of the G-Series laptops.
i saw a pretty thurough video the other day.
on the g51 there's no need to remove the screws on the bottom, it was easily popped out by the 5 tabs.
i used a small flathead screwdriver to pop the tabs, they don't take much pressure at all. once you get one end up you can lightly lift up to aid in the popping of the other tabs.
once open and out, i laid the keyboard back towards me. it was not nessacery to unhook the keyboard, but i did the first time i did it. i then took the plastic i wanted to use and laid over the back of the keyboard. there's a black band going around the out side of the back of the keyboard. the plastic you use needs to fit with in that band.
there are two screws that need to be removed as well. i didn't mess with putting the screws back in, once i put my film in (making sure to get it all the way to the bottom of the keyboard so that it covers all the rows of keys) i used a little clear tape.
i put it along the sides and then over the back. i used two at the top, one at each side, and then two at the bottom.
when seperating the led light panel care must be taken that you don't completely remove it. the object is to break the seal, open it enough to slide the color film you want to use, then seal it up.
i fiddled with it while the laptop was on, but this obviously should be recommended.
another mistake i made when hooking it back up was to hook the backlight power cord into the top of the black connector instead of the bottom of it. easy mistake to make.
the effect is quite nice. the blue was ok, but came out to faint, so it was a very light blue. a darker blue would produce a nicer effect, as i'm sure a darker red would too.
