1) I turned off Hibernate in my Windows 11 - in order to prevent "Sleep" mode automatic switch to Hibernate after several hours of inactivity.

> powercfg /a
The following sleep states are available on this system:
Standby (S3)
Hibernate
Fast Startup
The following sleep states are not available on this system:
Standby (S1)
The system firmware does not support this standby state.
Standby (S2)
The system firmware does not support this standby state.
Standby (S0 Low Power Idle)
The system firmware does not support this standby state.
Hybrid Sleep
The hypervisor does not support this standby state.

Fast Startup
Hibernation is not available.

2) Disabling Hibernate - deleted hidden C:\hiberfil.sys file (13 GB).
How big is your C:\hiberfil.sys file?
3) Fast Startup also disappeared.
But Claude Code thinks it is the right trade-off to lose "Fast Startup" together with losing hibernate:

But Claude Code thinks it is the right trade-off to lose "Fast Startup" together with losing hibernate:
Option A — Nuclear (simplest, recommended): disable hibernation entirely.
No more slow wakes, ever.
Frees ~7 GB disk space.
powercfg /hibernate off Run in an elevated Command Prompt.
⚠️ Side effect: this also disables Fast Startup (boot-from-shutdown will be slightly slower — usually a few seconds).
Given you have an SSD-grade wake-from-S3 of ~3 seconds but hibernate wake of ~13–20 seconds, this is almost certainly the right trade-off.
