In order to enable auto rotate on a T10 Tablet you must enable it in the BIOS. By default the auto rotate option is disabled. Turn on the tablet or reboot the tablet and tap the delete key repeatedly until you get into the BIOS. Navigate to the Configuration tab and change Screen Rotation from disabled to enabled. Go to the Exit tab and choose Exit Saving Changes. Now when you boot into Windows you should be able to turn the tablet and see auto rotate work. This will only work for Windows 7, if using Windows 8 you must install the Windows 7 video driver before auto rotate will work. By installing the video driver in Windows 8 you will lose some features outlined here.
