Attention: Before you start installing the wireless LAN 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.
To replace the wireless LAN card, do the following:
1. Disable the built-in battery. See "Disabling the built-in battery" on page 77.
2. Close the computer display, and turn the computer over.
3. Remove the base cover. See "Replacing the base cover" on page 79.
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 that secures the wireless LAN card.
