AC A D A P T ER C O NN EC T O R — Attach the AC adapter to the computer.
The AC adapter converts AC power to the DC power required by the computer. You
can connect the AC adapter with your computer turned either on or off.
CAUTION: The AC adapter works with electrical outlets
worldwide. However, power connectors and power strips vary
among countries. Using an incompatible cable or improperly
connecting the cable to the power strip or electrical outlet may
cause fire or equipment damage.
NOTICE: When you disconnect the AC adapter from the computer, grasp the
adapter cable connector, not the cable itself, and pull firmly but gently to avoid
damaging the cable.
