Your computer might be equipped with a wireless-WAN card. To replace the wireless-WAN card, do the
following:
Attention: Before you start installing a wireless-WAN card, touch a metal table or a grounded metal object.
This action reduces any static electricity from your body. Static electricity could damage the card.
1. Disconnect the ac power from the computer and turn off the computer. Close the computer display and
turn the computer over.
2. Remove the removable battery. See "Replacing the removable battery" on page 113.
3. Remove the bottom cover. See "Replacing the bottom cover" on page 116.
4. If a tool is provided with the new wireless-WAN card to help you disconnect cables, use the tool to
disconnect the cables from the wireless-WAN card. Otherwise, hold the cable connector with your
fingers and gently disconnect the cables from the wireless-WAN card.
Note: A Mylar film might cover the wireless WAN card. To access the wireless WAN card, open the film
first.
