CPU/Coreboard

• Check for proper seating of the CPU coreboard.

WiFi Antenna

The WiFi antenna is attached to the door, facing outwards, covered by the GB label. The other end is a U.FL micro-coax cable fitting and it simply presses onto the socket located on the coreboard.

• REMOVAL: Gently lift the WiFi cable connection up & off with a screwdriver.

• ATTACHMENT: orient the fitting over the socket and press gently down. The cable should be oriented as shown for proper seating.

LCD display connectors:

The LVDS (Low-Voltage Differential Signaling) cable provides the screen details (pixel control).

• Possible symptoms of malfunction include: scrambled video, lines in video, missing colors.

The backlight cable provides power to the display panel.

• A typical symptom of malfunction is no video (a “dead screen”).

For the technically adept, the other ends of these 2 cables connect to the LED display panel.

2. Remove the four mounting nuts:
