Cause
"Sleep" is a Modern Standby session (Hibernate). It turns off the screen, disables some hardware, and leaves other hardware in low-power mode. It is intended to be used when you are traveling short distances, not overnight.
Hibernate offers a reliable method of saving battery power while preserving your session. However, it is the most time-consuming option to process a shutdown and resume.
The machine does not go into Deep Sleep and stays in Normal Sleep. Applications remain in Low-Power mode + Network Staying in Low-Power mode + Network. This allows the system to wake up instantly when needed. However, this can drain battery power.
