Using the sensor data provided by the Active Protection System, the program will auto rotate the screen to the desired orientation.
Although IBM/Lenovo has software that does exactly this, it does not work for non-tablet versions. This program differs from the official one in that it allows you to customise the exact laptop orientation for the rotation to kick in. You can also select which orientation to (de)activate.
For non-Thinkpad machines, this tool can work as a regular screen rotation shortcut on the tray. See readme file for details.
Problems such as failure to rotate or blank screens may occur on certain systems. If you experience any issues, I appreciate it if you can post on the forum. Include your machine type, OS version, graphics card model and graphics driver version.
Requirements: Thinkpad Active Protection System driver. Windows XP or above. (32 and 64 bit supported)
