#Power & Sleep

caffeinate holds sleep off while a command runs, or for a fixed number of seconds.

pmset -g batt shows charge state; system_profiler SPPowerDataType adds condition and cycle count.

Use systemctl suspend for sleep-to-RAM and systemctl hibernate for sleep-to-disk, plus hybrid-sleep and suspend-then-hibernate variants.

Restore the missing Hibernate option and the hiberfil.sys file it depends on, from an admin prompt.

Use shutdown /s /t to make Windows power off automatically after a chosen number of seconds, and shutdown /a to cancel it.

Disable adapter power management so Wi-Fi doesn't disconnect every time the PC sleeps.

Install and enable TLP so Linux automatically applies power-saving settings for battery operation; check results with tlp-stat.

Read the current battery percentage, charging status and estimated remaining runtime in PowerShell with Win32_Battery.

Disable or re-enable Windows Fast Startup (hybrid boot) with the HiberbootEnabled registry value to fix shutdown and dual-boot problems.

Reboot or power off macOS with the built-in shutdown command — handy when the menu bar or remote session misbehaves.

pmset -g custom prints the live sleep configuration separately for battery and charger.

pmset includes two one-shot commands: displaysleepnow blanks the screen, sleepnow puts the whole Mac to sleep.
