DANGER
During electrical storms, do not perform any replacement and do not connect the telephone cable
to or disconnect it from the telephone outlet on the wall.
Attention: Before you start installing the 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.
Some computers might come with a wireless WAN card. To replace the wireless WAN card, do the following:
1. Disable the built-in batteries. See "Disabling the built-in batteries" on page 113.
2. Close the computer display, and turn the computer over.
3. Remove the bottom cover. See "Replacing the bottom cover" on page 114.
4. If a tool is provided with the new card to help you disconnect cables, use the tool to disconnect the
cables from the old card. If no such a tool is provided, hold the cable connector with your fingers and
gently disconnect each cable from the old card.
5. Remove the screw. The card is released from the secured position and pivots upward.
