The Compaq nx9010 is a laptop computer with an Intel Pentium 4 or Celeron processor and a 15-inch flat-panel display. The nx9010 has an internal Ethernet adaptor and dial-up modem. It was released just before internal wireless adaptors became ubiquitous on laptops. Although the Compaq nx9010 has an internal mini PCI slot for a wireless adaptor, the wireless adaptor is an optional extra that may not be installed on your laptop. You can purchase this part and install it on your own.
Shut the Compaq nx9010 down and place it on a soft work surface that will not scratch it. Place the nx9010 on the surface facedown with the battery compartment facing away from you. Take the battery pack out of the nx9010 before continuing.
Remove the two Phillips-head screws from the plastic cover near the front of the nx9010. Remove the cover to reveal the empty mini PCI slot. You should see two small cables with metal connectors on the ends; move these aside so the wireless card will not cover them.
Install the wireless card with the label facing up so that the gold contacts on the bottom go fully into the slot while the top part of the card is over the metal clasps. Push the top part of the card down until the clasps lock into the notches in each side of the card.
Connect the two cables on the inside of the mini PCI compartment to the antenna posts on the wireless card.
Replace the mini PCI compartment cover and screw it down.
Replace the battery pack, return the nx9010 to its original position and reconnect all removed cables.
