Is your laptop heating up or draining battery even when it’s asleep? Modern Standby (S0) might be the hidden culprit.

What Is Modern Standby?

“Modern Standby,” or S0 Sleep Mode, allows your PC to stay connected while sleeping—receiving emails, updates, etc.
It sounds helpful, but often results in:

• Overheating during sleep

• Faster battery drain

• Unresponsive wake-ups

Most users don’t know this feature exists, and Microsoft doesn’t offer a GUI to turn it off.
