Setting Up the Computer
Before you set up the computer for the first time, ensure that
■ The computer is using AC power.
■ The computer is not docked in a docking station.
Charging the Battery Pack for the First Time
The battery pack begins to charge when the computer is connected
to external power.
Although a new battery pack can be used to power the computer
after receiving a partial charge, Compaq recommends that a new
battery pack be allowed to fully charge before the computer is
disconnected from external power or before the battery pack is
removed from the computer.
IMPORTANT:The battery charge level lights on a new battery pack
accurately display the percent of a full charge remaining in the
battery pack only after the battery has been fully charged.
A new battery pack fully charges in approximately
■ 2.5 hours when the computer is connected to external power
and not being used.
■ 4 hours when the computer is connected to external power and
being used.

Connecting the Power Cord
1 Place the computer on a flat surface near an electrical outlet.
2 Plug the power cord into the power connector on the rear
panel of the computer 1, then into the electrical outlet 2.
NOTE: In Japan, you must first plug the power cord into the 3-to-2-
prong plug adapter included with the computer. Ensure that the
ground wire is connected to a safe earth ground, then plug the 3-
to-2-prong plug adapter into the electrical outlet.
!WARNING: To reduce the risk of personal injury, electric shock,
fire, or damage to the equipment:
■ Do not disable the power cord grounding plug. The grounding
plug is an important safety feature.
■ Plug the equipment into a grounded (earthed) electrical outlet
that is easily accessible at all times.
■ Disconnect power from the equipment by unplugging the
power cord from the electrical outlet.
■ Do not place anything on power cords or cables. Arrange them
so that no one may accidentally step on or trip over them. Do
not pull on a cord or cable. When unplugging from the
electrical outlet, grasp the cord by the plug.
