Not at all. If you want to put away some sensitive electronics for use after an EMP hit, you need to place them in a proper Faraday cage. If we really do experience EMP damage, I would recommend leaving the "good stuff" in the cage until you are very certain another EMP is not coming. It may be a VERY long time before replacement equipment could be manufactured again. Today's computers are designed and built with yesterday's computers. It's difficult to start from zip.
