Step 4) Keyboard Removal (Part 1)
Flip your laptop back over onto its proper side and open it up, folding the LCD screen as far back as it can comfortably go in order to make sure it doesn't get in the way of anything. Some people recommend covering it with a towel or other cloth to protect it from scratches, but this shouldn't be necessary. If you feel particularly nervous about ruining it, however, feel free to take this precaution.
With the Vaio laptop there are little buttons you have to push to release the keyboard, and this is where the flathead screwdriver, spudger, or otherwise flat-yet-durable device comes in handy. If you look right above the F4 key, you'll see a little switch that needs to be flicked upwards in order to get it to release. Carefully stick the flat object in between the keyboard and laptop itself, and then pry the left side of the keyboard out of its holding position. While it's raised, hold it up with one hand and use the other hand to flick the release button right about where the F12 key is located.
Be extra careful with this, though: If you notice that the keyboard is not lifting out, don't force it. Go back and check to make sure both switches are fully flicked, and once you flick them properly, lift the keyboard all the way out. Don't pull too fast though, because there is still something holding it in.
