This policy setting lets you configure when energy saver becomes active. By default, energy saver is set to 'BalancedSavings'. On devices with no battery, energy saver is disabled by default and does not become active. Please note that Windows Energy Saver settings can influence when energy saver becomes active on all devices. Individual sites may be blocked from participating in energy saver by configuring the policy 'SleepingTabsBlockedForUrls' (Block sleeping tabs on specific sites). Set this policy to 'AlwaysActive' and energy saver is always active. Set this policy to 'NeverActive' and energy saver never becomes active. Set this policy to 'ActiveWhenUnplugged' and energy saver becomes active when the device is unplugged. Set this policy to 'ActiveWhenUnpluggedBatteryLow' and energy saver becomes active when the device is unplugged and the battery is low. Set this policy to 'BalancedSavings' and when the device is unplugged, energy saver takes moderate steps to save battery. When the device is unplugged and the battery is low, energy saver takes extra steps to save battery. Set this policy to 'MaximumSavings' and when the device is unplugged or unplugged and the battery is low, energy saver takes extra steps to save battery. If the device does not have a battery, energy saver never becomes active in any mode other than 'AlwaysActive' unless the setting or 'EfficiencyModeEnabled' (Efficiency mode enabled) policy is enabled. This policy has no effect if the 'EfficiencyModeEnabled' policy is disabled.

BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
