	If the offline and online computer are kept close together (in the same room) then theoretically information can still be transmitted past the air gap using certain sidechannels like: RF, audio, light, magnetic, thermal. For further details see the wikipedia article on [https://en.wikipedia.org/wiki/Air-gap_malware Air-gap malware]. For this reason it could be a good idea to keep the offline and online computers physically far apart, and unplug the power cable from the laptop so it runs on battery power only.
