The Reserve Battery Notification Level machine setting should be configured correctly. Specify the percentage of battery capacity remaining that triggers the reserve power mode. If you enable this policy setting, you must enter a numeric value (percentage) to set the battery level that triggers the reserve power notification. If you disable this policy setting or do not configure it, users can see and change this setting.
