Removal Procedure
1. Mini-PCI models only: release the latches at the sides of the card, so that its free edge pops up,
and carefully pull the card out of its connector.
2. Mini-PCI models only: disconnect the cables that connect the mini-PCI panel to the
motherboard, and remove the panel and the mini-PCI card (still connected) from the motherboard.

pressing down on the rear of the connector (near the wires) as you pull it out.
