Use A Surge Protector
Even if you always follow the above advice about unplugging your computer during a storm, you still need to worry about power surges frying your computer.
Power surges can happen for many reasons, including bad wiring, transformer explosions, squirrels or possums eating through power lines, and problems with other large electrical appliances in your house. You also have to worry about thunderstorms that happen when you aren’t home to unplug your computer.
To protect against unexpected power problems, buy a surge protector. Some of them even come with guarantees to replace hundreds of thousands of nairas of computer equipment if an electrical surge gets past the surge protector. This is an important part of computer hardware maintenance.
