Windows 7 provides enhanced UI notifications to alert users when battery life notifications help users understand how much power is left in their portable computers’ batteries. In Windows 7, battery life notifications are more prominent, and they encourage users to connect to a power source before the computer automatically hibernates.
At 7 percent battery life, Windows 7 alerts users that the battery is entering Reserve Power mode and prompts them to connect to a power source.
Windows 7 automatically puts the computer in Hibernate mode when battery life is at 5 percent. IT pros can configure low battery thresholds by using Group Policy and Windows Management Instrumentation (WMI).
