How to Insert a PC Card into Your Laptop
This is cinchy. Just stick the PC Card into the slot on your laptop. It slides in only one way: The narrow edge with the holes goes in first.
If the computer is on, Windows recognizes the card instantly, similar to what's shown in the below figure. At that point, you can start using the card or whatever other features with which it just blessed your laptop.
Some cards may require extra software to make them go. It says so in the card's manual. Other cards, like many USB devices, can just be plugged in, and they're off and running.
The most common type of PC Card that’s available is a wireless networking card. Installing the card is only half the battle; the rest involves properly configuring your laptop to connect to a wireless network.
