Protecting against power source problems

Surge suppressors, line conditioners, and uninterruptible power supplies (UPS) can help protect your system against power source problems.

Surge suppressors

During a power surge, the voltage level of electricity coming into your system can increase far above normal for a few milliseconds. This may cause data to be lost or the system may be damaged as a result. To protect against power surges, use a surge suppressor. The surge suppressor absorbs voltage surges and prevents them from reaching your system.

A surge suppressor plugs directly into an electrical outlet. You should connect your computer, monitor, and other devices to the surge suppressor.

If you have a modem, make sure your surge suppressor has jacks for the telephone and modem cables. Power surges can pass through telephone wires as well as electrical wires.
