Adverse Power Protection
Power supplies have built-in protection against adverse power conditions. However, the best protection for a computer is to unplug it during a power outage or thunderstorm. Surge protectors and UPSs (uninterruptible power supplies) are commonly used to protect against adverse power conditions. A line conditioner can also be used. Each device has a specific purpose and guards against certain conditions. A technician must be familiar with each device in order to make recommendations for customers.
