11 Power cord set requirements
The power supplies on some computers have external power switches. The voltage select switch feature on
the computer permits it to operate from any line voltage between 100-120 or 220-240 volts AC. Power
supplies on those computers that do not have external power switches are equipped with internal switches
that sense the incoming voltage and automatically switch to the proper voltage.
The power cord set received with the computer meets the requirements for use in the country where you
purchased the equipment.
Power cord sets for use in other countries must meet the requirements of the country where you use the
computer.

2
