22Useful InformationOperation environment Place the computer on a flat stable surface not subject to shock, vibration, and danger of dropping. Do not place thecomputer upright or turn it over. If the computer is exposed to an extremely strong impact, it may become damaged. Operating environmentTemperature: Operation : 0 °C to 50 °C (IEC60068-2-1, 2) *1 -10 °C to 50 °C (IEC60068-2-1, 2) *1Storage : -20 °C to 60 °CHumidity: Operation : 30% to 80% RH (No condensation)Storage : 30% to 90% RH (No condensation) Even within the above temperature/humidity ranges, operation for a long time in extreme environments, smokingnearby, or operation in places where oil is used or where there is a lot of dust will result in the product deteriorationand will shorten the product life.*1 Do not expose the skin to this product when using the product in a hot or cold environment. ( page 4)If the computer is wet in temperatures of 0 °C or below, freeze damage may occur. Make sure to dry off the com-puter in such temperatures. Do not place the computer in the following areas, otherwise the computer may be damaged. Near electronic equipment. Image distortion or noise may occur. In extremely high or low temperature. As the computer can become hot during operation, keep it away from items that are sensitive to heat.Handling cautionsThis computer is designed to minimize shock to parts such as the LCD and the hard disk drive and equipped with adrip-proof keyboard, but no warranty is provided against any trouble caused by shock. Be extremely careful when han-dling the computer. When carrying the computer: Turn off the computer. Remove all external devices, cables, Smart Cards and other protruding objects. Do not drop or hit the computer against solid objects. Do not leave the display open. Do not grip the display part. Do not put anything (e.g., a piece of paper) between the display and keyboard. When you board an airplane, take the computer with you and never put it in your checked luggage. When using thecomputer on airplane, follow the airline’s instructions. When carrying a spare battery, put it in a plastic bag to protect its terminals. The touch pad is designed to be used by a finger tip. Do not place any object on its surface and do not press downstrongly with sharp-pointed or hard objects that may leave marks (e.g., nails, pencils and ball point pens). Avoid any harmful substances such as oil from getting into the touch pad. The pointer may not work correctly. Be careful not to get injured by dropping or getting hit when carrying the computer. Use only the included digitizer pen to touch the screen. Do not place any object on its surface and do not pressdown strongly with sharp-pointed or hard objects that may leave marks (e.g., nails, pencils and ball point pens). Do not use the screen when dust or dirt (e.g., oil) is on the screen. Otherwise foreign particles on the screen/digi-tizer pen can scratch the screen surface or obstruct the digitizer pen operation. Use the digitizer pen only for touching the screen. Using it for any other purpose may damage the digitizer pen andresult in scratches on the screen. The digitizer uses electromagnetic induction and may not work properly near strong electrical field or magnetic fieldsuch as: Near AM radio base station or relay station antennas Near CRT displays that generate strong electromagnetic field noiseMove the digitizer away from such locations so it will work properly. The pointer cannot follow the digitizer pen movement if you move the digitizer pen too quickly. When the battery indicator does not light onThe battery indicator may not light on even if the AC adaptor and the battery pack are correctly connected to the com-puter, due to the following reasons. The AC adaptor’s protection function may be working. In this case, pull out the AC cord and wait for more than1 minute before reconnecting the AC cord. When the battery is fully charged and the computer is not operating (i.e., it is turned off or in sleep mode), the pow-er supply from the AC adaptor stops and power consumption is inhibited (except when the Wake Up from LAN orthe Power On by LAN function is enabled). In this case, the indicator will light green upon connecting the AC adap-tor, but only for a moment.Handling and Maintenance
