Replacing a PCI Express Mini Card with three connectors
If your computer has a Multiple Input Multiple Output (MIMO) feature, a PCI Express Mini Card that has three
connectors comes with the computer. To replace the card for the MIMO feature, do the following:
1. Turn off the computer; then disconnect the ac power adapter and all cables from the computer. Wait
three to five minutes to let the computer cool.
2. Close the computer display, and turn the computer over.
3. Remove the battery. See "Replacing the battery" on page 71.
4. Remove the keyboard. See "Replacing the keyboard" on page 78.
5. If a tool for removing connectors is included in the package with the new card, use it to disconnect the
cables from the card. If no such tool is included, disconnect the cables by picking up the connectors
with your fingers and gently unplugging them.
