Can I use my computer or laptop during a storm?
Can I use my computer or laptop during a storm? Is it safe to use laptops and desktops in a lightning storm? Do you need to shut down your computer in a thunderstorm?

It depends on what context you ask. A laptop or computer is unlikely to attract lightning. But it can burn if plugged into electricity during a storm.
If you have a laptop, charge it and disconnect it from the power supply during a storm. Then you can use it safely. A desktop computer is unlikely to have batteries, so it's better not to use it in this situation.
Get yourself a decent surge protector. Good slats even protect against storms. They must be equipped with a varistor.
Another option is to insure the equipment against overvoltage, but it is expensive.
I have everything at home on surge protectors, and in addition, when there is a storm, I disconnect everything from the power, except kitchen appliances. Fridge however, she better walk. I don't feel like setting the clock in the oven either.
Using a computer or laptop during a storm carries some risk, especially if the device is connected to the mains. The main threats are:
- Surges: Lightning striking a power line can cause a surge in voltage that travels along cables and can damage electronic devices connected to the grid. To minimize the risk, you can use surge protectors.
- Data corruption: a sudden power surge may result in the loss of data on your computer if it was being written to disk at the time.
- Personal safety: although less likely, there is a theoretical risk of electric shock if you are in contact with the device during impact lightning.
If your laptop is charged and you are using it on battery power, there is less risk, but there is still the possibility of damage from power surges on a telephone or internet network connected via cable.
To stay safe during a storm, it is best to:
- Disconnect the computer from the electrical network.
- Disconnect all wired connections to the Internet and other devices.
- If possible, stop working on the computer until the storm ends.
If you need to work on your computer during a storm, it is recommended to use a laptop on battery power and a wireless internet connection, which reduces the risk of damage from power surges.
