•Disconnect your notebook from telephone, LAN and power lines when an electrical storm threatens. If you have a fax/modem, lightning can travel in on the phone line and can damage both the fax/modem and the system unit. Lightning can also travel in on power lines and damage your monitor and system unit.

Note

Please note that the product warranty does not apply if damage to your notebook is the result of a lightning strike.

•Be sure that notebook power is off before you connect or disconnect a cable (except USB and IEEE 1394 devices, that can be hot-swapped and hot-plugged). Never make cable changes when the notebook power is on. Doing so could damage your notebook and its peripherals.

•Place your notebook away from direct sunlight and extreme temperatures. Operate and store your notebook within the recommended temperatures and humidity levels.
