My laptop is warm in my bag in the morning, or will not wake up

Modern Standby (S0) keeps background processes alive during 'sleep'. On some laptops it runs wild: the laptop never truly sleeps and overheats in the bag.

Try this first

  1. 1Shut down fully or use 'Hibernate' for long breaks. Closing the lid only for short moments.
  2. 2Check Settings > System > Power & battery > Sleep settings. Set 'On lid close' to Hibernate instead of Sleep for bag time.
  3. 3PowerShell as admin: powercfg /sleepstudy. Generates a report of what kept your laptop awake. Often a specific driver or app.
  4. 4Wake timers off: powercfg /waketimers. Shows processes allowed to wake the laptop.

When to bring us in

Modern Standby that is structurally broken: we can adjust by policy or, via laptop firmware, revert to old S3 sleep. Not possible on every model.
