This is one area where Apple has it pretty right. A Mac will do somethings when ‘asleep’ like download emails and texts. It also can broadcast its location if the ‘Find Me’ function is on. If it’s plugged into power then backups will also run, and background app updates will happen. It does this in a low power mode, so it won’t get hot enough to need fans. It’s worked flawlessly for 20 years. Meanwhile all our PCs are set to ‘never sleep’ and just get shutdown when not in use. I never trust a PC laptop to wake successfully from sleep just by closing the lid.
Great and all, but this is a literal press release. It could be PR spruiking, it could be pump’n’dump play, it could be friggin genuinely great. No way to know from a press release.
