Protecting Against Electrostatic

Discharge

Electrostatic discharge (ESD) events can harm electronic

components inside your equipment. To prevent ESD damage,

you should discharge static electricity from your body before

you interact with any of your equipment's internal electronic

components by touching a metal grounded object, such as

an unpainted metal surface on your computer's I/O panel.

In addition, as you work inside the equipment,

periodically discharge any static charge your body may

have accumulated.

General Power Safety

Observe the following guidelines when connecting your

equipment to a power source:

•

Check the voltage rating before you connect the equipment

to an electrical outlet to ensure that the required voltage

and frequency match the available power source.

•

Your device is equipped with either an internal power

source or an external adapter. For internal power sources,

your device is equipped with one of the following:

–

An auto-sensing voltage circuit - Devices with

an auto-sensing voltage circuit do not have

a voltage selection switch on the back panel and

automatically detect the correct operating voltage.

Safety, Environmental, and Regulatory Information

–

A manual voltage selection switch - Devices with a

voltage selection switch on the back panel must be

manually set to operate at the correct operating

voltage. Set the switch to the position that most

closely matches the voltage used in your location.

NOTE: The switch on your system may be different

than the one pictured.

CAUTION: To help avoid damaging a computer with a

manual voltage selection switch, set the switch for the

voltage that most closely matches the AC power available

in your location.

•

To prevent electric shock, plug the equipment power cables

into properly grounded electrical outlets. If the equipment is

provided with a 3-prong power cable, do not use adapter

plugs that bypass the grounding feature, or remove the

grounding feature from the plug or adapter.

•

To remove a portable computer from all power sources,

turn the computer off, disconnect the AC adapter from the

electrical outlet, and remove any battery installed in the

battery bay or module bay.
