• To help avoid possible damage to the system board, wait 5 seconds after turning off the 
computer before disconnecting a device from the computer.
• To avoid shorting out your computer when disconnecting a network cable, first unplug 
the cable from the network adapter on the back of your computer, and then from the 
network jack. When reconnecting a network cable to your computer, first plug the cable 
into the network jack, and then into the network adapter.
• To help protect your computer from sudden, transient increases and decreases in 
electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply 
(UPS).
• Ensure that nothing rests on your computer’s cables and that the cables are not located 
where they can be stepped on or tripped over.
• Do not push any objects into the openings of your computer. Doing so can cause fire or 
electric shock by shorting out interior components.
• Keep your computer away from radiators and heat sources. Also, do not block cooling 
vents. Avoid placing loose papers underneath your computer; do not place your computer 
in a closed-in wall unit or on a bed, sofa, or rug.
• Do not spill food or liquids on your computer. If the computer gets wet, consult your 
User’s Guide.
• Do not use your computer during an electrical storm unless the AC adapter cable has 
been disconnected from the electrical outlet.
• When you use the AC adapter to run the computer, place the AC adapter in a ventilated 
area, such as a desk top or on the floor.
• The AC adapter may become hot during normal operation of your computer. Use care 
when handling the adapter during or immediately after operation.
