power - Is it bad to leave your computer on during a thunderstorm?


Generally when I hear the crack of thunder, my PC goes off immediately. Today I'm working though, and wondered - how bad is it to leave it on? If the power goes out, will it kill it?


I use a power strip - that protects it, right?

Answer



Most power strips don't provide surge protection, and then those that do provide a very basic level of protection. UPS battery backup units usually provide far better protection, but they themselves can also be damaged.


The best approach is to shut off your computers during a storm, and disconnect all the power cords (computer, monitor, speakers, printers, and other connected peripherals, etc.).


The risk is serious, and taking a short break from the computer to enjoy nature's power can actually be a really nice change of pace once in a while.


(As per comments below, I've added a picture of a good power bar to my answer here...)
