Important safety information
Correct usage procedures
Use ONLY the power cord, power adapter and battery pack shipped
with the computer. Never use these devices with another product.
Be sure the power outlet is suitable for the plug and provides the
correct voltage and current for the product you are using.
Danger:
• An unsuitable power supply may damage your computer and
can cause an electric shock or fire.
Do NOT use a power outlet, power cord, power adapter or battery
pack that appears to be damaged or corroded.
Do NOT share an electrical outlet with other home or commercial
appliances that draw large amounts of electricity.
If power strips are used, the load should NOT exceed the power strip’s
input rating. Unplug the power cord if there are any cracking, hissing,
or popping sounds, or if a strong odor comes from the computer.
Danger:
• Overloading the power supply may cause unstable voltages
which might damage the computer, data, attached devices, or
even cause a fire.
