Just turn off tablet mode. A tablet is a small, portable personal computer that uses a touch screen as the basic input device. The start menu can automatically open and close the tablet mode. The touch screen of a tablet computer (also known as tablet technology) allows users to work with a stylus or digital pen instead of a traditional keyboard or mouse. Users can use built-in handwriting recognition, on-screen soft keyboard, voice Recognition or a real keyboard (if the model is equipped) for input.
