Warning High voltages can enter your notebook through
both the power cord and the modem connection.
To protect your notebook and avoid electrical
shock, use a surge protector. If you have a
telephone modem, use a surge protector that has
a modem jack. If you have a cable modem, use a
surge protector that has an antenna/cable TV jack.
During an electrical storm, unplug both the surge
protector and the modem.
