• 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.
• Use appropriate virus detection software regularly to protect your notebook from computer
viruses.
• Place your notebook away from direct sunlight and extreme temperatures. Operate and
store your notebook within the recommended temperatures and humidity levels.
