What is Modern Standby on Windows laptops?

Modern Standby (S0ix) keeps minimal activity for instant wake, like a phone — but drains battery from background network tasks.

How to check if my Windows laptop uses Modern Standby?

Run `powercfg /a` in admin Terminal; look for "S0 Low Power Idle: Supported".

Shutdown with fast boot on, or hibernate — both cut drain to under 2%, vs 15-25% sleep loss.

🛡️ Security Tools

Bag unpacked, laptop cold, battery at 100%. No more Modern Standby surprises. Here's the data-driven switch that's saving my Windows machine.
