Turning On and Turning Off Your Internet PC 2-5

Using a Surge Suppressor

Use of a surge suppressor, line conditioner, or uninterruptible power supply (UPS),
may help to protect your computer from damage that may be caused by power
surges or sags.

Restarting Your Computer After a Power Failure

If a power failure occurs or you accidentally disconnect the power cord while the
computer is turned on, turn off the computer until you are sure normal service has
been restored. The next time you turn on the computer, ScanDisk may run to check
the hard disk for errors that may have been caused by the improper shutdown.

Electrical Storms

If you are expecting an electrical storm to pass through your area, it is a good idea
to ensure that your Internet PC is turned off. You should disconnect the modem
line from the telephone wall jack and remove all the computer power cords from
electrical outlets.
