The auto-rotate feature on the ThinkPad Twist running Windows 8 is controlled by the power manager module.    Early production models shipped with two different versions of this driver in the preload depending on date of manufacture (See details on versions GM6 and GM7 and initial functionality listed below).

UPDATED MODES OF OPERATION available NOV 30, 2012

Following the initial release of Twist, Lenovo updated the functionality to improve the customer experience in the 4 modes of operation - notebok/clamshell, stand, tablet, and tent mode.   These updates ensure the onscreen keyboard is more easily available, unwanted screen rotations / orientations eliminated, and the screen lock button functionality changes depending on mode.   These update require installation of GM8 version of the power manager and an updated BIOS version.   After these updates, the screen lock button will only lock the screen orientation while in tablet mode.   In other modes, this button will now flip the screen image - useful when shifting to tent mode.

To update, follow the instructions below to improve screen orientation in Microsoft Windows 8 on the ThinkPad Twist. For current users of the Twist, there is a new set of software updates that will enable better screen orientation and control operation. For new users to Twist, this same set of updates will insure consistent transitions to each of the four operating modes: Clamshell, Stand, Tablet, and Tent.  Full Tip with details available here on our support site.

Run ThinkVantage System Update to download driver updates. From the Start screen, type update. This will display the System Update App icon which will be located in the upper left corner of the display. Touch or click this icon to begin the update process.
