Replacing the SIM card
Before you start, print these instructions.
If your computer is equipped with a SIM card slot, your computer might require a SIM card to establish
wireless WAN connections. Depending on the country of delivery, you might need to purchase a SIM
card or a SIM card might already be installed in your computer or is part of the shipping contents that
come with your computer.
If you find a SIM card included in the shipping contents, a dummy card is installed in the SIM card slot.
Note: The SIM card is identified by the IC chip mounted on one side of the card.
To replace the SIM card, 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 it over.
3. Remove the battery. See “Replacing the battery” on page 67.
