Can I turn on the computer indoors during a thunderstorm?

Summer is the season when thunderstorms are common. Home computers are prone to lightning strikes, causing damage to computer hardware and communication failures. In order to avoid this and protect your property from loss, we recommend that you continue reading below. Content:

Lightning strikes are generally divided into direct lightning strikes and induction lightning strikes. Installing lightning rods on buildings can only prevent direct lightning strikes, while induction lightning strikes can harm indoor household appliances, especially computers, through externally connected lines. Therefore, it is necessary to pay attention to lightning protection during thunderstorms. The following lightning protection methods are for your reference:

1. Pay attention to regularly checking the grounding wire used by the computer. The casing of most computers is almost connected to this ground wire. Its main purpose is to protect personal safety. In addition, the ground wire can also eliminate the impact of static electricity on the equipment.

2. Keep a certain distance between the computer and the exterior walls and pillars of the building. Especially in high-rise buildings in cities, there are a lot of steel bars inside the columns. Because when the building you live in is struck by direct lightning or side lightning, strong lightning current will flow into the ground along the outer walls and pillars of the building. During this process, because a strong lightning current flows through the outer wall or pillar of the building, electric and magnetic fields are generated in the surrounding space. If the computer is too close to the outer wall or pillar, the integrated circuit module in the computer will There is a possibility of damage.

3. Try not to surf the Internet during thunderstorms, because lightning strikes may be introduced through the power line, burning out the MODEM, or even burning out the computer's network card, motherboard and other components.

4. Even if lightning is not directly introduced, under normal circumstances, network cards, modems, and computer power supplies are easily damaged during thunderstorms. The reason is that the equipment is directly connected with long lines, similar to radios. Antennas are sensitive to lightning space electromagnetic field induction, and integrated circuit modules are easily damaged and damaged (failure occurs within a week) under the instantaneous induction of high voltages.

5. When a thunderstorm approaches, try to unplug all the lines connected to the computer (including power cords, network cables, telephone lines, etc.). Although you may not necessarily have professional lightning protection facilities installed at home, as long as you start with the above small things, you can protect the safety of your computer to the maximum extent and reduce losses caused by lightning.
