If you plan to use the computer during a flight, check with the airline in advance. In-flight 
computer use is at the discretion of the airline. 
If the computer will be unused and disconnected from external power for more than 2 
weeks, remove the battery and store it separately. 
If you are shipping the computer or a drive, place it in a bubble-pack mailer or other 
suitable protective packaging and label the package “FRAGILE.” 
If the computer has a wireless device or a cell phone device installed, such as an 
802.11b/g, a Global System for Mobile Communications (GSM), or a General Packet 
Radio Service (GPRS) device, note that the use of these devices may be restricted in 
some environments. Such restrictions may apply onboard aircraft, in hospitals, near 
explosives, in hazardous locations, and so on. If you are uncertain of the policy that 
applies to the use of a particular device, ask for authorization to use it before you turn 
it on. 
If you are traveling internationally, follow these suggestions: 
◦ 
◦ 
Check the computer-related customs regulations for each country or region on 
your itinerary. 
Contact technical support to discuss power cord and adapter requirements for 
each location in which you plan to use the computer. Voltage, frequency, and plug 
configurations vary. 
WARNING! 
To reduce the risk of electric shock, fire, or damage to the 
equipment, do not attempt to power the computer with a voltage converter kit sold 
for appliances.
