Hi JennL,
This behavior is usually related to how Windows stores background battery policy settings. The option you’re changing in Power Options is only the visible toggle, and if the underlying policy or threshold values aren’t properly aligned, the setting may revert back to Off after sign-in or power state changes.
If you're on Windows Pro version, please ensure the low battery warning policy is enabled
- Press Win + R > type
gpedit.msc> Enter - Go to: Computer Configuration > Administrative Templates > System > Power Management > Notification Settings
- Set Low battery notification/warning = Enabled
You can also try these quick checking steps
1, Reset power plan
- Open Command Prompt (Admin)
- Run:
powercfg -restoredefaultschemes
2, Set a valid low battery level
- Go to Control Panel > Power Options > Change plan settings > Advanced
- Expand Battery and set:
- Low battery level = 10–20%
- Low battery notification = On (both options)
Once these values are consistent, the notification should remain enabled and behave as expected.
