In an airliner you're not likely to ever get a cold & dark aircraft unless you're the lucky schmuck who gets the first flight of the day out of Greenland after a week of sitting on the ramp.
Most will already have power applied and the packs will be blowing by the time you get to it, but not always. In the old days, the FFOTD had the engineer out on the ramp powering up the airplane, doing the walk around, setting radios, W&B, etc, etc, etc, ad infinitum, while the pilot and FO were getting weather and flight planning if they didn't already have a canned flight profile for their route.
Not sure how it's done today, but with crew changes, and almost non-stop running of the aircraft for revenue, C&D isn't as common as it was in the past.
When I get to the aircraft, it's already running on APU, packs are on...before start, and only minor set-up is needed on the FE panel. I expect my Virtual FE to have taken care of the mundane but important part of setting up the aircraft.
I still check everything including the FE panel by checklist, but it's usually pretty quick...unless I'm the unlucky schmo who gets the FFOTD!
