But it would also likely take out the grid itself. If all of the massive power cables strewn all over, connected to very large expensive power station transformers, become overloaded at the same time from a CME, I don't predict good things for those transformers and a lot of other things. The laptop would not be able to be recharged without solar or something. It takes a long time (1-2 years is my understanding) to get one single transformer at a power station, under ideal conditions. They are basically made to order, and backlogged.
