Longer Battery Life
Windows 7 helps give portable computers longer battery life so that mobile users can be more productive and get more work done on a single battery charge. For example, integrated displays are the largest power consumer on typical portable computers. Adaptive Display Brightness automatically dims the display after a period of inactivity.
Windows 7 has enhanced processor power management to help deliver energy savings and performance on today’s mobile platforms. Windows 7 also provides users with a richer experience when travelling by focusing on performance optimizations and core infrastructure optimizations which provide benefit across several user scenarios. It helps common tasks, such as watching standard definition movies, use less power, enabling users to watch more movies on single battery charge. Windows 7 spins discs more efficiently during DVD playback; as a result, it consumes less processing power. Even with more efficient DVD playback, it gives users the same seamless DVD experience: The disc automatically starts without any user interaction.
The Windows Troubleshooting Platform helps users detect and repair power policy issues that cause poor power usage for their machine. Users can be more self-sufficient and productive by being able to quickly resolve their power issues.
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).
