Power Protection Devices
Several devices are available that protect against power fluctuations and
failures:
• Surge protectors
• Line conditioners
• Uninterruptible power supplies (UPS)
Surge Protectors
Surge protectors and power strips equipped with surge protection help to
prevent damage to your computer from voltage spikes that can occur during
electrical storms or following power interruptions. The level of protection is
usually commensurate with the cost of the surge protector. Some surge
protector manufacturers include warranty coverage for certain types of
damage. Dell recommends that you carefully read the device warranty when
choosing a surge protector. Compare joule ratings to determine the relative
effectiveness of different devices.
NOTICE: Most surge protectors do not protect against lightning strikes. Dell
recommends that you disconnect your computer from the electrical outlet when
lightning occurs in your area.
NOTICE: Surge protectors do not protect against power fluctuations or power
interruptions.
