I have to face facts: I'll never know everything about Tablet PCs. Things change to fast and there is too much information about each one. Luckily, I have customers who ask great questions or tell me things I need to know. Here is one such item.
If you have a Motion F5v or C5v Tablet PC, you can choose an option to allow the display to rotate depending on which way you turn the device.
In the Taskbar (those icons in the lower, right hand corner of your display), you will see a letter M with a black swoosh on the top and a blue one on the bottom. If you don't see it, click the upward arrow on the taskbar. When you tap on this you'll see a menu. Choose Options and then click Automatic Display Rotation if it isn't already checked. Now you can turn your Motion F5v 90 degrees and the screen will automatically turn.
