An introduction to Lenovo programs This topic provides a brief introduction to Lenovo programs. Depending on your computer model, some of the programs might not be available. 14 ThinkPad P70 User Guide Access Connections™ (Windows 7) The Access Connections program is a connectivity assistant program for creating and managing location profiles. Each location profile stores all the network and Internet configuration settings needed for connecting to a network infrastructure from a specific location such as a home or an office. By switching between location profiles as you move your computer from place to place, you can quickly and easily connect to a network with no need to manually reconfigure your settings and restart the computer each time. Active Protection System™ (Windows 7 and Windows 10) The Active Protection System program protects your internal storage drive (such as hard disk drive) when the shock sensor inside your computer detects a condition that could damage the drive, such as system tilt, excessive vibration, or shock. The internal storage drive is less vulnerable to damage when it is not operating. This is because when the internal storage drive is not operating, the system stops it from spinning, and might also move the read and write heads of the drive to areas that do not contain data. As soon as the shock sensor senses that the environment is stable again (minimal change in system tilt, vibration, or shock), it turns on the internal storage drive. Auto Scroll Utility (Windows 7) This program enhances your experience with window operation. The window position of a foreground application is automatically adjusted. The scroll bar on a user interface is also automatically adjusted. Communications Utility (Windows 7) The Communications Utility program enables you to configure settings for the integrated camera and audio devices.
