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.
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.
If your computer uses an AC adapter:
Use only the provided Alienware AC adapter approved for use with this device. •
Use of another AC adapter may cause a fire or explosion.
Use only the following AC adapter family with your notebook:
•
-P01E: PA-9E
Place the AC adapter in a ventilated area, such as a desk top or on the floor, •
when you use it to run the computer or to charge the battery.
WARNING: Using an incompatible battery may increase the risk of fire or
explosion. Replace the battery only with a compatible battery purchased
from Alienware that is designed to work with your Alienware computer.
Do not use a battery from other computers with your computer.
