I suspect that might argue for a micro-ITX or non-fan laptop, because they could be put in the sort of standby mode that would comsume the same power as a handful of LEDs, but which would keep their motherboards and/or cases warm enough to cook off moisture.
Strangely, one of the reasons I am wanting a large battery bank (three to four 8D AGMs) is so I can have the luxury not of running a bigger fridge, but to handle the "phantom power" requirements of running small electronics draws (SSB in receive mode, AIS, radar in "guard" mode, laptop), assuming I've made my amps via solar, wind and occasional alternator charge-ups.
