You could keep it in a faraday cage. Along with a generator and batteries. And an antenna.
I am not being facetious. In the event they are describing the entire grid would be shot. In a CME event whatever side of the earth is pointed towards the sun would get fried.
If a CME event happen, the gas supplies will run out quickly. I am setting up an additional Solar panel system that will power all my HF/UHF/VHF Comms and Laptops.
I am off the grid more than half the year when I am boating. With lithium batteries NOW starting to become a reasonably priced alternative, the RV will be added to the list of Li batteries needed.
I am assuming that some of my flexible solar panels (and associated spare electronics) will survive as they are normally stored away (not connected but NOT in a Faraday shield). I could be unpleasantly surprised..... I don't think from what I have read that any CME event will be strong enough to get the not connected spares. The results from the N. Koreans may be different. And with any CME event, we should get plenty of warning. If you really like your electronics, then disconnect them before the event arrives.
Except for air conditioning and heat, solar works for someone who is electrically knowledgeable. I just took a set of AGM batteries off the sail boat that were 8 years old so if you don't abuse them, they will last.
