• PCI Express Mini Card for wireless WAN.
• Keyboard.s
• PCI Express Mini Card for wireless LAN.
• Keyboard bezel assembly, FPC cable, and Bluethooth daughter card (BDC-2.1).

When installing:

• Before you attach the fan assembly to the computer, apply thermal grease, at an amount of 0.2 grams, on the parts marked [a] as in the following figures. Either too much or too less application of grease can cause a thermal problem due to imperfect contact with a component. For the fan in the integrated graphics models, you need to peel the thin film off from the thermal rubber marked [b].

For Discrete graphics models:

• When attaching the fan assembly to the frame, take care not to damage the heat sink ([a]) of the fan assembly.

• Make sure that the fan connector is attached firmly.
