While the temperature will not feel hot to the touch, if you maintain physical contact with the computer for a long time, for example if you rest the computer on your lap or if you keep your hands on the palm rest, your skin might suffer a low-heat injury.

■If the computer has been used for a long time, avoid direct contact with the metal plate supporting the various interface ports as this can become hot.

■The surface of the AC adaptor can become hot when in use but this condition does not indicate a malfunction. If you need to transport the AC adaptor, you should disconnect it and let it cool before moving it.

■Do not lay the AC adaptor on a material that is sensitive to heat as the material could become damaged.
