Your computer has a Modem Daughter Card (MDC) slot, in which you can install a Modem Daughter Card.


  • During electrical storms, do not connect the cable to or disconnect it from the telephone outlet on the wall.
  • Electric current from power, telephone, and communication cables is hazardous. To avoid shock hazard, disconnect the cables before opening the cover of this slot.
  • Before you start installing a MDC, touch a metal table or a grounded metal object. This action reduces any static electricity from your body. The static electricity could damage the card.

To replace the MDC, do as follows:

  1. Turn off the computer; then disconnect the AC adapter and all cables from the computer.
  2. Close the computer display, and turn the computer over.
  3. Remove the battery.
  4. Remove the keyboard.
  5. Remove the two screws securing the Card.
