Setting Up Your Computer

Surge protectors and power strips equipped with surge protection help 

prevent damage to your computer from voltage spikes that can occur during 

electrical storms or after power interruptions. Some surge protector 

manufacturers include warranty coverage for certain types of damage. 

Carefully read the device warranty when choosing a surge protector. A device 

with a higher joule rating offers more protection. Compare joule ratings to 

determine the relative effectiveness of different devices.

Most surge protectors do not protect against power fluctuations or 

power interruptions caused by nearby lightning strikes. When lightning occurs in 

your area, disconnect the telephone line from the telephone wall jack and 

disconnect your computer from the electrical outlet.

Many surge protectors have a telephone jack for modem protection. See the 

surge protector documentation for modem connection instructions.

Not all surge protectors offer network adapter protection. Disconnect the 

network cable from the network wall jack during electrical storms.

Line conditioners do not protect against power interruptions.

Line conditioners are designed to maintain AC voltage at a fairly constant 

level.

Loss of power while data is being saved to the hard drive may result in 

data loss or file damage.

 

To ensure maximum battery operating time, connect only your computer to a 

UPS. Connect other devices, such as a printer, to a separate power strip that 

provides surge protection.

A UPS protects against power fluctuations and interruptions. UPS devices 

contain a battery that provides temporary power to connected devices when 

AC power is interrupted. The battery charges while AC power is available. See 

the UPS manufacturer documentation for information on battery operating 

time and to ensure that the device is approved by Underwriters Laboratories 

(UL).
