3: Frame Screws
As shown in the picture, cautiously tilt the LCD screen forward, within its metal frame bracket. Remove the screws in the metal bracket framing either side of the screen. Note the position of the Wi-Fi antenna (and BlueTooth, if there's one), so that you'll know how it goes back together.
Once more, it will be helpful to put all the tiny screws and covers in one place, preferrably a small container in which they will not get lost or attached to your clothing.
