Make sure you know how to install and remove wireless cards, per 1101 exam Objective 1.1.

Mini PCIe Mini PCIe is based on the full-size PCIe expansion bus found in a desktop PC. They are both 64-bit interfaces; the Mini PCIe is just smaller. Depending on the manufacturer, this is also called PCI Express Mini Card, Mini PCI Express, Mini PCI-E, or simply MiniCard.

One of the most common uses for the Mini PCIe slot is for wireless network cards, such as Wi-Fi or Bluetooth. A cellular wireless card can also be Mini PCIe. Unlike on a desktop PCIe expansion card, there is no external access to a Mini PCIe card, so you can’t use it to add new external ports. There is usually a cover on the bottom of the laptop that you can remove to expose the Mini PCIe slot. There may be just a single connection for a card, or it may accept multiple Mini PCIe cards. Power down the laptop and remove the battery. Then expose the slot, pull an installed card straight out of the slot, and insert a new one straight in, keeping in mind that the card typically sits parallel to the motherboard and the slot is perpendicular to that.

Figure 14-2 shows a Wi-Fi wireless LAN adapter installed in a Mini PCIe slot. This particular adapter is actually two in one, as it is both a Wi-Fi adapter and a Bluetooth adapter. The antennas for this card run through the small black cable visible on the upper right of the card and running to the upper left. It leads up through the lid hinge into the lid behind the screen. If the antenna fails, it requires dismantling the screen of the laptop.
