Is it necessary to turn off the computer when it thunders?

It is best not to use a computer in a thunderstorm, because if there is lightning high voltage, it may lead to a short power outage, which may easily damage the hard disk or puncture the motherboard.

Lightning can be divided into direct lightning and inductive lightning. Lightning induction is the main "culprit" that affects the safety of household appliances in lightning season. The so-called lightning induction refers to the high-intensity electromagnetic induction generated by various metal pipes and wires entering the building when lightning occurs, which leads to a sudden increase in the conductor voltage of the wires, leading to the burning or even burning of household appliances.

Television sets, air conditioners, computers and refrigerators are the most vulnerable to lightning strikes. Due to the need of outdoor circuit and signal transmission, TV has become the "number one target" of lightning. An air conditioner consists of an outdoor unit and an indoor unit. When air conditioning is used in thunderstorm weather, lightning is easily transmitted from outdoor unit to indoor unit, causing short circuit and fire.

Lightning protection description

1. In case of lightning, thunder and rainstorm, visitors should immediately turn off the indoor TV, tape recorder, stereo, air conditioner and other electrical appliances to avoid using electricity. It's safer in the middle of the room when it thunders. Don't stay under the electric light, and don't lean against posts, walls, doors and windows, so as to avoid accidents caused by induced electricity when it thunders.

2. Don't use an umbrella with a metal handle in thunderstorm weather. Take off glasses, watches and belts with metal frames. If you travel by bike, you should leave the bike as soon as possible and stay away from other metal objects to avoid being struck by lightning.
