Linux has a hibernate function, but the power button activates Sleep, which is higher-consumption. There may be a way to set it to actually hibernate on button press, but I’ve only seen Hibernation via Desktop Mode.
Sleep = keep processes in memory = more power consumption.
Hibernation = write most processes to disk and keep only vital system processes in memory = less power consumption.
