■ It’s possible that a voltage spike, power outage, or brownout has occurred.
Symptoms of voltage spikes include a flickering video display, unexpected computer
startups, and the computer not responding to your commands. A voltage spike can

backup copies of your data files. Prevent voltage spikes by installing a surge
suppressor made for use with computers between the power outlet and the computer
power cord.
