When the Active Protection system is enabled, it protects your hard drive when the shock sensor inside your ThinkPad computer detects a situation that could potentially damage the hard drive. The protection system stops your hard drive by moving the read/write heads of the hard drive to areas that do not contain data, and may also stop spinning the disks of the hard drive. The hard drive is less vulnerable to damage when it is not in operation. The protection system turns the hard drive on again once the shock sensor detects a stable environment (minimal change in system tilt, vibration, or shock). When the protection system detects system motion and stops your hard drive, the following message is displayed.
- The Active Protection system can be used only with the primary hard drive on Microsoft Windows XP or Microsoft Windows 2000. The protection system will not control a second hard drive that is either attached externally to your computer or installed in your computer's Ultrabay.
- The Active Protection system is enabled by default whenever the computer and operating system are operating.
- It is automatically disabled while the computer is:
- Loading the operating system
- Entering Standby or hibernation mode
- In standby or hibernation mode
- Resuming normal operation after being in standby or hibernation mode
- Being shut down
- Turned off
- The Active Protection system is supported on the following ThinkPad systems:
- ThinkPad R50, R51, and R52 systems
- ThinkPad T41/p, T42/p, T43/p, and T60/p systems
- ThinkPad X40, X41, X41 Tablet, X60, and X60s systems
- ThinkPad Z60m and Z60t systems
- The system will not be able to access the hard disk drive during the time that the Active Protection system has unloaded the hard disk drive heads due to a tilt or drop motion being detected. This can result in the operating system appearing to be temporarily sluggish or non-responsive.
The Active Protection system system tray icon (when selected to be displayed) shows the status of the shock sensor, as follows:
|The shock sensor is disabled (the Active Protection system is not activated).|
|The shock sensor is enabled, but no shock has been detected.|
|The shock sensor is enabled, and repetitive vibration is detected that does not cause the operation of the hard drive to be stopped.|
|The shock sensor is manually suspended, the hard disk drive is running.|
|The shock sensor is enabled. A shock has been detected, and the operation of the hard drive is stopped.|
To see the list of options for the protection system, double-click the icon on the system tray. The properties window is displayed, and the following check boxes are presented:
- The check box for enabling the Active Protection system
- If this check box is selected, the Active Protection system is enabled. If a shock is detected, the computer stops the hard drive operation to protect the drive from physical damage.
- The slider for adjusting the shock detection sensitivity
- The available settings are:
- The check box for temporarily ignoring repetitive, low level shocks
- Select this option to avoid frequent stops of the hard drive when you use the computer in an environment where the shock sensor detects repetitive, low-level shocks, such as those experienced when riding on a train or airplane. If enabled, this option functions when the ratio of the duration of stopping the hard drive caused by the protection system responding to low-level shocks exceeds a specific percentage within a certain amount of time (stop threshold). Once the shock sensor detects a stable environment for an extended amount of time, this option resets so that the sensitivity for received shocks returns to normal. In all cases, the protection system will always stop the hard disk when heavy shocks are detected.
- The check box for enabling the option to manually suspend the Active Protection System temporarily.
- The available settings are:
- 0.5 minute
- 1 minute
- 2 minutes
- 3 minutes
- The suspend now button will suspend the Active Protection System for the set amount of time.
- The check box for displaying the icon on the system tray
- If the check box is selected, the icon showing the status of the shock sensor is displayed on the system tray.
Select the About tab to view the version of the Active Protection System
To check the operational status of the Active Protection system, double-click the icon on the system tray. The properties window is displayed. Then select the Real-time Status tab.
The Status is displayed graphically, and changes with real-time inputs. The laptop graphic will move coinciding with movement of the system, and the status icon will change as the Active Protection system changes the operational status of the hard drive based on the prediction algorithm for shocks and/or vibrations in near future. See the following examples:
- The following is displayed when the system is tilted to the right and the hard drive is stopped..
- The following is displayed when the Active Protection system is disabled.
Click here to view How to test the Active Protection hardware.Both the hardware sensor integrated into the system board and the software are needed for the Active Protection system to function. If the software is not installed on a system that has the hardware, the Active Protection system will not function. If the Active Protection system software is installed on a system that does not have the Active Protection system hardware, an error message will be displayed stating that the system does not support the Active Protection system and it should be uninstalled.
