Windows Low Battery Warning Registry Setting

Windows manages low battery alerts through power configuration settings stored in the Windows Registry. This article details the exact registry keys and GUID values responsible for toggling the low battery notification check, as well as the step-by-step process to enable or disable it using the Registry Editor (regedit).

Registry Path for Low Battery Notifications

Low battery notification settings are stored per power plan within the following registry path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes\<PowerScheme_GUID>\e73a048d-bf27-4f12-9731-8b2076e8891f\bcded951-187b-4d05-bccc-f7e51960c258

Understanding the GUIDs

• Subgroup GUID (e73a048d-bf27-4f12-9731-8b2076e8891f): Represents the Battery subgroup in Windows power management.
• Setting GUID (bcded951-187b-4d05-bccc-f7e51960c258): Controls the Low battery notification trigger.

Modifying the Setting

Inside the bcded951-187b-4d05-bccc-f7e51960c258 key, two DWORD (32-bit) values determine whether the check is active:

• DCSettingIndex: Controls the notification when running on battery power.
• ACSettingIndex: Controls the notification when plugged into AC power.

Value Definitions: * 0 = Low battery notification turned Off (Windows will not check/warn). * 1 = Low battery notification turned On (Windows will check/warn).

Making the Setting Visible in Windows UI

If the option is hidden inside the classic Power Options Control Panel menu, you can expose it using the master power setting key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\e73a048d-bf27-4f12-9731-8b2076e8891f\bcded951-187b-4d05-bccc-f7e51960c258

1. Locate the Attributes DWORD value.
2. Set Attributes to 2 to make the “Low battery notification” setting visible in Advanced Power Options.
3. Set Attributes to 1 to hide the setting.
