Protecting Yourself and the Computer

T±

Turn the computer off before disconnecting or installing any cables.

When the computer is connected to an AC power source there is always voltage applied to

the system board. You must disconnect the power cord from the power source before

opening the computer to prevent system board or component damage.

For personal safety and to ensure that the computer does not overheat, Compaq

recommends that you install the computer cover or access panel before turning on the

computer.
