The ThinkVantage(R) Active Protection System protects your hard disk drive when the shock sensor inside your ThinkPad(R) computer detects a condition that could damage the drive, such as system tilt, excessive vibration, or shock. The hard disk drive is less vulnerable to damage when it is not operating; so the system stops it from spinning, and may also move the read/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 the hard disk drive on.
