Replacing a laptop keyboard isn't difficult, if you know what you are doing. Most of the time, because laptops keyboards seem so well integrated, it is tough to get started without knowing where to start. After having been forced to replace my keyboard, due to a milkshake mishap, I learned a few things about replacing the keyboard on my Asus A8J series laptop. I'll be guiding you through the steps and pointing you through the trouble spots that I experiened, so that you won't have to go through them. The same steps should also work for the Asus W3J as they both use the same keyboard.
What You'll Need
In order to get this operation underway, I recommend that you have the following available to you:
A small Philips and Flat Head Screwdriver
A can of compressed air
Cue-Tips and a bit of water to remove any residue or sludge under the old keyboard
Soft Cleaning Cloth large enough to cover the screen.
Your brand new replacement keyboard
Your old laptop with the busted ass keyboard
Once you're got all the materials, it is time to begin.
